Abstract:

The present study was undertaken to compare the performance of 8 (eight) breeding bulls of three different genetic groups such as Brahman × local (4 bulls), Holstein Friesian × local (2 bulls) and Red Chittagong (2 bulls) based on libido, semen quality and fertility. Semen parameters were evaluated from 30 ejaculates from each bull and fertility rate was calculated based on 60-days non-return rate via AI using these semen samples. Genetic group of breeding bulls had significant (p<0.05) effect on libido. Holstein Friesian cross breeding bulls showed significantly (p<0.05) highest libido (3.77±0.15) followed by Brahman cross (3.38±0.07) and lowest in Red Chittagong (RC) breeding bulls (2.96±0.11). Semen attributes also significantly affected by the different genetic group of bulls. Holstein Friesian crossbred breeding bulls with highest libido provided significantly (p<0.01) highest volume of semen (5.63±0.16 ml) per ejaculate, progressive motility (74.73±0.76%), live sperm (84.18±0.62%) and normal sperm (83.18±1.47%) whereas these parameters were significantly (p<0.01) lowest in RC breeding bulls. Moreover, libido showed a strong and positive correlation with all these semen parameters. The fertility rate was also significantly highest (p<0.05) in Holstein Friesian crossbred breeding bull (63.67±1.46%), followed by Brahman crossbred (58.86±1.05%) and lowest in RC breeding bulls (53.42±0.85%). These results suggested that semen quality is positively correlated with the libido of breeding bulls and quality is important for higher fertility. Therefore, libido as well as semen quality evaluation may be important criteria to discard the breeding bulls with poor fertility in an AI program. Bang. J. Anim. Sci. 2018. 47 (2): 61-67

Abstract:

The present study was conducted to evaluate the frozen semen quality in terms of different motility patterns and fertility of imported pure Holstein Friesian and Sahiwal breeding bulls maintained under farming condition of Bangladesh. 100% pure Holstein Friesian and Sahiwal breeding bulls were imported and thereafter reared in the American dairy limited (ADL). Semen samples were collected once a week, processed and frozen in the laboratory of ADL. On the day of collection, semen volume and sperm concentration measured immediately after collection. Different motility patterns of spermatozoa (progressive, fast, slow, local, immotile) were measured by Computer Assisted Semen Analyzer (CASA). Effect of breed was found significant (p<0.05) on semen volume and sperm concentration. The semen volume (ml/ejaculate) and sperm concentration (×106) were found to be 6.13±0.28 and 1664.28±62.41 in Holstein Friesian breeding bulls whereas 5.26±0.17 and 2036.00±43.99 in Sahiwal bulls, respectively. The progressive motility, fast motility, slow motility and local motility were significantly (p<0.05) higher in Holstein Friesian bulls than that of Sahiwal bulls both before and after freezing. Different motility patterns such as progressive, fast, slow, local and immotile motility were found to be 89.22±0.45%, 75.97±0.67%, 9.10±0.36%, 4.25±0.15% and 10.05±0.41% in Holstein Friesian bulls whereas 84.98±0.89%, 65.99±0.92%, 11.88±0.37%, 5.65±0.19% and 15.69±0.54% in Sahiwal breeding bulls, respectively before freezing. On the other hand, after freezing, the progressive, fast, slow, local and immotile spermatozoa were found to be 68.19±0.46%, 53.39±2.01%, 9.21±0.46%, 8.47±0.72% and 26.76±2.01% in Holstein Friesian bulls whereas 56.54±0.25%, 42.52±0.67%, 11.11±0.55%, 13.04±1.24% and 30.45±1.58% in Sahiwal bulls, respectively. Non-return rate was found insignificant between the breeds and it was 64.19% in Holstein Friesian and 64.71% in Sahiwal bulls. In conclusion, frozen semen quality of Holstein Friesian pure breed is better than that of Sahiwal breeding bulls but fertility of both breeds are similar. Therefore, frozen semen of both breeds can be used in the field level for the genetic improvement of cattle. Asian Australas. J. Biosci. Biotechnol. 2020, 5 (1), 33-41

Abstract:

In order to increase milk production per cow, Friesian cows are being bred to Holstein bulls. As yet, there are few pure-bred Holsteins in commercial production in Ireland but there are increasing numbers of Holstein x Friesian and Holstein x (Holstein x Friesian) calves available for beef production. The main difference between Holstein and Friesian steers is that the former have poorer carcass conformation. The use of anabolic agents and an increase in slaughter weight might improve carcass conformation. The objectives of the present experiment were (1) to compare the growth and carcass composition of 3/4 Holstein and Friesian steers, (2) to measure the effects of implantation with anabolic agents in both these breed types, (3) to determine the effects of a higher feeding level and delayed slaughter on carcass traits.

Abstract:

AbstractThe increased use of Holstein genetic material in the Irish dairy herd has consequences for beef production. In all, 42 spring-born steers [14 Holsteins (HO), 14 Friesian (FR) and 14 Charolais × Holstein-Friesian (CH)] were reared to slaughter at between 26 and 37 mo of age. Carcass weight was higher and the lipid concentration of m. longissimus thoracis et lumborum was lower (P < 0.05) for CH than the dairy breeds. Overall acceptability tended to be lower (P = 0.055) while tenderness, texture and chewiness were lower (P < 0.05) for CH compared with the dairy breeds. The proportion of C16:1 in the total lipid tended to be lower (P = 0.055) for CH than the dairy breeds. Replacing male offspring of traditional “Irish” Friesian bulls with offspring from a genetically superior (from a dairy perspective) strain of Holstein bull had no commercially important impact on beef nutritional or eating quality.

Abstract:

Records collected over a period of four months from October 1978 to January 1979 from four Holstein-Friesian and four N'dama hulls, were used to study the relationship between testicular size and sperm output. Semen samples were collected from the bulls twice a week using the artificial vagina and non-oestrous female teasers. The means (± s.e.) of testicular measurements for Holstein-Friesian and N'danta, respectively, were 35.6 ± 1.8 and 7.9 ± 0.3cm. for scrotal circumference, 12.6 ± 0.3 and 7.7 ± 0.8cm for testis length, 6.7 ± 0.3 and 3.7 ± 0.2em for testis diameter. Calculated mean testicular volumes were 296.8 I 22.2 and 57.4 ± 10.1m1 respectively for Holstein-Friesian and N'dama bulls. T-he mean total sperm per ejaculate were 8.80 t 3.045 x 109 for (be Holstein-Friesian and 3.03 ± 0.905 x 109 for the N'dama bulls. Simple correlations for Holstein-Friesian and N'damn in the same order, were between body weight and scrotal dr. rumference 0.49 and 0.66, body weight and sperm output/einculate 0.48 and 0.88, scrotal circumference and testicular volume 0.74 and 0.60. scrotal circumference and sperm outpuilejactilete 0.18 and 0.69, and testicular volume and sperm output/ejaculate —.45 and 0.84. Regression equations for predicting sperm oatput/ejaculate from testicular volume are given as Y = .13.458 — .031 X and Y' = - .650 + 0,038 x respectively, for holstein-Friesian and N'dania bulls.

Abstract:

Slaughter Value of Young Polish Black-and-White, White-Backed, Polish Holstein-Friesian and Limousin Bulls Under Semi-Intensive FatteningThe objective of the present study was to compare the slaughter value of young bulls of two breeds included in the genetic resources conservation programme, namely Polish Black-White and White-backed with young Polish Holstein-Friesian (dairy type) and Limousin (beef type) bulls. This is the first study to evaluate the meat performance traits of White-backed cattle in several-centuries history of the breed in Poland. It was determined that populations of White-backed and Polish Black-and-White cattle represent the dual-purpose type desirable in the genetic resources conservation programme. The indices obtained for the analysed traits of slaughter value from young Polish Black-and-White and White-backed bulls were intermediate between Polish Holstein-Friesian (dairy type) and Limousin (beef type), but closer to those of the Polish Holstein-Friesian breed. The analysed muscles of young bulls had a very similar content of basic chemical components. The relatively high amount of proteins (22.85-23.23%) in musculus longissimus lumborum and in musculus semintendinosus (22.43-23.06%) should be emphasized.

Abstract:

Crossing of Friesian-Holstein dairy cows with beef breed bulls is widely practised. Recently the Italian Piemontese and Romagnola beef breeds have been imported into Ireland, but they have not been evaluated. The objective of this study was to compare the progeny of these breeds and Friesians for carcass traits. General productivity traits have been reported elsewhere (Keane, 2001).

Abstract:

Pedigree data from national breeding value evaluations were used in calculation of the coefficient and rate of inbreeding, average coefficient and rate of relationship and generation intervals for the Finnish Ayrshire and Holstein-Friesian dairy cattle populations. The data had 1,366,555 Ayrshire and 377,869 Holstein-Friesian animals. The mean coefficient of inbreeding for Ayrshire and Holstein-Friesian animals born in the 1990s was 2.29% and 0.90%, respectively, and the trend was towards higher inbreeding values. The average coefficient of relationship, mean increase in inbreeding and generation interval was calculated for bulls born between 1976 and 1999, and for cows born between 1986 and 1999. The mean coefficient of relationship of Ayrshire bulls increased 2.22 %-units per generation and inbreeding increased 0.20 %-units per generation during the years studied. The mean coefficient of relationship of Finnish Holstein-Friesian bulls increased 0.96 %-units per generation and inbreeding 0.17 %-units per generation. The mean coefficient of relationship and inbreeding of Ayrshire cows increased 0.38 %-units and 0.31 %-units per generation, respectively. For Holstein-Friesian cows the mean coefficient of relationship and inbreeding increased 0.25 %-units and 0.11 %-units per generation, respectively. Results show that inbreeding is low and it is increasing slowly in both breeds. However, especially the coefficients of relationship of Ayrshire bulls are high in some age classes and this may lead into faster increase in coefficients of inbreeding.;

Abstract:

With the current situation of low profitability in the beef industry, producers must aim to produce beef efficiently and at minimum cost. In view of the ready availability of Holstein Friesian bull calves as a by-product of the dairy industry, the rearing and finishing of these animals offers a possible source of income to beef producers. The objective of the present study was to examine the influence of slaughter weight on feed efficiency and production characteristics of Holstein-Friesian bulls offered a cereal-based diet.

Abstract:

The objective of this study was to determine beef production traits of purebred Holstein-Friesian (Hol) and Hol×beef breed crossbred bulls. The data collected from slaughterhouses included observations of 87323 purebred Hol, 783 Hol×Aberdeen angus (Hol×Ab), 621 Hol×Blonde d’Aquitaine (Hol×Ba), 562 Hol×Charolais (Hol×Ch), 349 Hol×Hereford (Hol×Hf), 1691 Hol×Limousin (Hol×Li) and 570 Hol×Simmental (Hol×Si) bulls. For estimating valuable cuttings also a separate dataset was collected and included observations of 8806 purebred Hol, 57 Hol×Ab, 29 Hol×Ba, 22 Hol×Ch, 15 Hol×Hf, 111 Hol×Li and 58 Hol×Si bulls. Crossbreeding Hol cows with late maturing breeds (Ba, Ch, Li, Si) had favorable effects on carcass gain, conformation and proportion of high value joints of the progeny when compared to purebred Hol bulls. No advantages in proportion of valuable cuttings seemed to be obtained by crossbreeding with Ab or Hf breeds, while the improvements in gain and conformation were intermediate compared to the late maturing crossbreds.

Abstract The aim of the study was to find out whether carriers of new genetic defect Cholesterol Deficiency (CD) occur in the population of Polish Holstein-Friesian bulls. Twenty seven bulls were included in the analysis. Bulls were selected as having in the pedigree known carrier of CD (Maughlin Storm CANM000005457798). All bulls were diagnosed by the test described by Menzi et al. (2016) by using allele-specific PCR. Among 27 bulls, 9 new CD carriers were found. Our results show that causal mutation for CD is already transmitted to Polish Holstein-Friesian cattle. The results are sufficient ground to take practical action in order to avoid further spreading of mutation causing CD.

Abstract:

This study aimed to investigate the effects of breed, age, scrotal circumference, Body Condition Score (BCS), season and nutrition on bull semen quality at breeding bull station of Ejab Alliance Limited, Thakurgaon, Bangladesh. A total of 777 ejaculates were collected from 25 bulls (Holstein-Friesian-10; Sahiwal-15). All semen parameters were significantly (P<0.05) higher in Sahiwal bulls than in Holstein-Friesian. The volume, individual motility, mass activity and sperm morphology were significantly (P<0.05) higher in bulls aged >3.5 - 4.5 years than in younger (2.5 - 3.5 years) and older bulls (>4.5 years). Scrotal circumference significantly (P<0.05) affected all the parameters of semen quality. The highest values were observed in bulls with scrotal circumference 31.1 - 33.0 cm and the lowest in bulls with scrotal circumference of 33.1 cm and less. The volume, individual motility, mass activity and sperm morphology were higher (P<0.05) in bulls with BCS of 4 to 4.5 than in bulls with BCS of >4.5 to 5. Significantly (P<0.05) highest values regarding semen quality were in winter and the lowest in summer. Vitamin ADE supplementation significantly (P<0.05) improved the semen quality. It is suggested that Sahiwal breeds may be reared at the bull station in the subtropical climate of Bangladesh. Semen should be collected during winter in bulls of >3.5 to 4.5 years of age with moderate scrotal circumference and BCS. The Bangladesh Veterinarian (2018) 35(1&2): 32-39

Abstract The aim of this study was to evaluate the effect of C/T missense mutation (SOX5) gene on selected parameters of non-frozen semen in Polish Holstein – Friesian bulls. Three hundred and sixty eight bulls were genotyped by the PCR-Rsa I technique. Semen was collected and evaluated by standardized procedure used in an AI station. Significant associations were found between SOX5 genotypes and sperm concentrations (p=0.020) and sperm motility (p=0.014). Bulls with TT genotype had the lowest values of both traits. Our results demonstrate that C/T missense mutation within the SOX5 gene is involved in bull sperm quality.

Abstract The objective of this study was to determine the effect of genotype and carcass conformation class on the slaughter quality of 200 young bulls, including 108 crossbred beef bulls and 92 Holstein- Friesians (HF), aged 21-22 months, selected in the lairage. The lean meat content was estimated and body measurements were taken before slaughter. After slaughter, the carcasses were graded according to the EUROP system, and carcass quality parameters were determined. Intramuscular fat was extracted from samples of m. longissimus dorsi, and the fatty acid profile of extracted fat was determined by gas chromatography. 61.11% carcasses of crossbred beef bulls were graded in the conformation class R, and 56.53% carcasses of Holstein-Friesians were classified as O. The majority of carcasses belonged to fat class 2, which was not consistent with intramuscular fat content. Within the same conformation classes, crossbred beef bulls were characterized by higher slaughter quality than Holstein-Friesian bulls. Meat from hybrid beef bulls had a higher (by 0.42% on average) content of fat with a more desirable composition. Since the population size of beef cattle will probably not increase in the nearest future, efforts should be continued to optimize the production of high-quality beef from dairy cattle herds.

Abstract:

The continuing trend for increased use of Holstein genetics in dairy herds has resulted in a large number of Holstein-Friesian bull calves becoming available, at low cost, as a potential resource for the beef industry. However, whilst these calves have been bred for dairy traits, which are negatively correlated to many important beef traits (e.g. carcass conformation), it is important to determine the potential yield of boned out joints from these animals, in order to facilitate an assessment of commercial carcass value. The objective of the present study was to evaluate the effect of slaughter weight on yield of boned out joints from Holstein-Friesian bulls and steers offered a cereal-based diet.

Abstract:

Abstract The aim of this paper was to verify the hypothesis whether carriers of genetic defect Brachyspina occur in the Polish Holstein-Friesian Cattle. PCR method was used to screen 78 Polish Holstein-Friesian bulls. Eight bulls were identified as heterozygotes for 3,3 kb deletion in the FANCI gene – the mutation causing Brachyspina defect. All carriers were sons of 3 sires: Cleitus Jabot, Sandy-Valley Bolton ET and Coyne-Farms Dorcy ET which were descendants of the US sire Sweet Haven Tradition (HOUSAM 1682485). Systematic screening of young bulls having in the pedigree Barchyspina carrier is necessary to prevent spreading of the recessive mutation in the dairy cattle population in Poland.

Abstract:

SUMMARYGenetic changes have taken place in the Spanish cattle population as a result of breed replacement and crossbreeding as well as from H61stein-Friesian strain influence. In the last 20 years interest in the Holstein (Canada, and the USA) has increased, so that the North American strain today contributes to a high percentage of the genes in the Spanish Friesian herd. It is not yet clear what effect the introduction of quotas will have on the breed and strain composition of the Spanish dairy population, but in view of the role that Friesian type animals play in beef production, any major change in milk price will affect the genetic make-up. Estimated percentages of Holstein genes (bull catalogue, bulls, genetic evaluation and utilized semen doses) are given.

Abstract:

This study aimed to investigate the effects of slaughter age (young vs. old), muscle type (Longissimus dorsi (LD), Gluteus medius (GM)) and fat deposits (kidney knob and channel fat, subcutaneous fat, intramuscular fat) on chemical, organoleptic, textural characteristics and fatty acid composition of Holstein Friesian bull meat. For this purpose, the carcasses of 26 Holstein Friesian bulls that had been fattened on the same private farm were assigned to two experimental groups based on their age at slaughter: a young group (YG) (average age: 17.0 ± 1.0 months old) and an old group (OG) (average age: 22.0 ± 1.0 months old). The percentage of crude protein, panel tenderness score, polyunsaturated fatty acid (PUFA) and saturated fatty acid (SFA) content, the PUFA/SFA ratio and the hypocholesterolemic fatty acid (DFA)/hypercholesterolemic fatty acid (OFA) ratio of the bull carcasses decreased significantly with increasing slaughter age. By contrast, the OFA content of the carcasses significantly increased (p < 0.05) with increasing slaughter age. Advanced slaughter age resulted in lower panel tenderness scores. Additionally, the meat of the bulls in the OG was considered to be less healthy because of the less desirable fatty acid composition and nutritional indices, such as the PUFA/SFA and hypocholesterolemic/hypercholesterolemic ratios, compared to the meat from the bulls in the YG. Furthermore, the intramuscular fat and internal fat contained high percentages of PUFA and SFA and high PUFA/SFA and hypocholesterolemic/hypercholesterolemic ratios. Interestingly, the percentage of OFA content in the internal and intramuscular fat tissues decreased with increasing slaughter age. In conclusion, this study provided evidence that slaughter age and muscle and fat type are essential sources of variations in the textural characteristics, sensory panel attributes and fatty acid profile of meat from Holstein Friesian bulls.

Abstract:

In this study, we characterized genetic diversity in the gene bank for Dutch native cattle breeds. A total of 715 bulls from seven native breeds and a sample of 165 Holstein Friesian bulls were included. Genotype data were used to calculate genetic similarities. Based on these similarities, most breeds were clearly differentiated, except for two breeds (Deep Red and Improved Red and White) that have recently been derived from the MRY breed, and for the Dutch Friesian and Dutch Friesian Red, which have frequently exchanged bulls. Optimal contribution selection (OCS) was used to construct core sets of bulls with a minimized similarity. The composition of the gene bank appeared to be partly optimized in the semen collection process, i.e., the mean similarity within breeds based on the current number of straws per bull was 0.32% to 1.49% lower than when each bull would have contributed equally. Mean similarity could be further reduced within core sets by 0.34% to 2.79% using OCS. Material not needed for the core sets can be made available for supporting in situ populations and for research. Our findings provide insight in genetic diversity in Dutch cattle breeds and help to prioritize material in gene banking.

Calculations were based on a sample of 100 non-sib artificial insemination bulls. Assuming one known parent the nine loci suggested for routine testing exhibited exclusion probabilities of 99.84% in the Ayrshires and 99.91% in the Holstein-Friesians. The addition of markers INRA23 and TGLA53, recommended for further investigations, increased the attained values to 99.94% in Ayrshires and to 99.98% in Holstein-Friesians. The recommended core set of six microsatellites provided a combined exclusion probability of 98.25% in Ayrshires and 99.32% in Holstein-Friesians. Although the combined values were high in general, a relatively low level of polymorphism was detected in some instances.;

Abstract:

Over the past 10 years, dairy breeding in the United Kingdom has switched from British Friesian to the North American type Holstein. Many of the bulls entering progeny testing in the UK in that period were sourced from overseas bull mothers, especially from the US. The aim of this study was to compare current predictions of the genetic merit of those bulls, using pedigree information, with the performance of their UK daughters.

Abstract:

Holstein-Friesian bull calves, although bred for dairy traits, are available at low cost as a potential resource for the beef industry. Finishing of these cattle on intensive feeding regimes has become more attractive in recent years reflecting, inter alia, the reduction in cereal prices and availability of subsidy payments. However, in the future, market-driven economy, production systems must become more efficient if they are to remain viable. The objective of the present study was to evaluate the effect of slaughter weight on production characteristics of Holstein-Friesian bulls offered cereal-based diets, whilst also evaluating the effects of sexual status on performance attributes.

Abstract:

Meat from Holstein-Friesian bulls, which are bred for dairy traits, is generally regarded as low quality and is usually destined for the commodity (mince) market. However, given their ready availability as a by-product from the dairy herd, it is important to determine if meat from these animals would be suited to higher-priced markets. Furthermore, meat from bulls is generally considered to be lower quality than that from steers, though there is a paucity of data comparing meat from both sources. Hence, the objective of this study was to evaluate the effect of slaughter weight on meat quality characteristics of Holstein-Friesian bulls and steers offered a cereal-based ration.

Abstract:

Meat from commercial breed cattle are very often used to crossbreed with dairy breeds. The effect of heterosis is most evident when crossbreeds are genetically different from each other. Therefore, the aim of the study was to determine the influence of breed types on the nutritional and pro-health quality of beef. The experiment was conducted on 62 bulls from three breeds: Limousin, Polish Holstein-Friesian, and Polish Holstein-Friesian (PHF) × Limousin. During the fattening period, the animals were fed ad libitum using the same diet. Bulls were slaughtered at 21–23 months of age. The meat of PHF × Limousin hybrids was characterized by the lowest level of SFA and the highest content of n-3 PUFA fatty acids, carnosine, and α-tocopherol compared to the values obtained for the Polish Holstein-Friesian and Limousin breeds. In the case of PHF × Limousin hybrids, there was a 6% increase in n-3 PUFA, 21% in carnosine, and 66% in α-tocopherol compared to the Polish Holstein-Friesian breed. Commodity crossbreeding significantly improved the quality of beef analyzed in this study, resulting in similar or even better results than purebred cattle. This meant that beef from the hybrids with PHF was of the best nutritional and health-promoting quality.

Abstract:

he aim of this study, conducted under identical environmental conditions and the stanchion barn housing system, was to compare milking performance traits and somatic cell count in milk of daughters sired by Holstein-Friesian Black-and-White bulls from various origin groups. Cows were divided into three groups depending on the region of sire's origin, i.e. Polish bulls, bulls from other European countries (the Czech Republic, France and Germany) and bulls from the USA. Analyses were conducted applying the following experimental conditions: the age group of cows (primiparous vs. multiparous), stage of lactation (≤ 40 days, from 41 to 100 days, from 101 to 200 days and > 200 days) and season of the year (spring, summer, autumn and winter). Results of this study indicate that at the stanchion barn housing system of dairy cows in order to increase milk yields the use of semen from bulls of imported Holstein-Friesian Black-and-White bulls seems to be beneficial. However, daughters of US bulls may be prone to elevated somatic cell counts in milk. In turn, cows sired by Polish bulls can be characterised by favourable milk solids contents.

Abstract:

Abstract The objective of this study was to estimate the genetic parameters of conformation traits in Polish Holstein-Friesian bulls evaluated for registration in the herd book and for entry into progeny testing. Data were 8 linearly scored (1-9 scale) and 6 composite (scored from 50 to 100) conformation traits of 2,738 young bulls born between 2001 and 2011. The multiple-trait REML method was applied for (co)variance component estimation. The linear model included fixed linear regressions on age at evaluation (from 10 to 23 months), fixed effects of year of birth, fixed effects of herd-classifier, and random animal effect. Heritability estimates for all analysed traits were within the range of 0.04-0.37. Among the 6 composite type traits, heritability was highest for size and for overall conformation score. The lowest heritability was for feet and legs. Among the linearly scored traits, heritability was the lowest for rear legs - side view and foot angle, and the highest for rump angle and muscularity of front end. Composite traits showed the highest genetic correlations with muscularity and final score playing the dominant role. Genetic correlations among linear traits were low and moderate (0.02-0.53). The relatively low genetic and phenotypic correlations indicated that no conformation trait of bulls can be improved by indirect selection alone. More research is needed to establish relationship between bull conformation traits and the conformation of their progeny.

Abstract:

This study aimed to determine the post-thawing spermatozoa quality of Holstein-Friesian (HF) bulls at different ages. The samples were HF frozen semen of 3, 5, and 8-years -old age group produced by the Singosari National Artificial Insemination Center. Nine samples of each group were randomly purposive sampling, thawed in 37ºC water for 15 seconds, and assessed on the percentage of viability, motility, and abnormality of spermatozoa. The obtained data were analyzed using the ANOVA method, followed by Duncan's multiple range test at a 95% confidence level. The result showed that post-thawing spermatozoa viability in 5 and 8-year-old HF bull were 67 ± 6.67%, and 78 ± 7.59, both were higher (p <0.05) compared to 62.78 ± 5.76% in HF bulls 3-yearsold group. Likewise, the motility of those bull aged 5 and 8 years (69.44 ± 6.82 and 65.00 ± 9.68%, respectively) were higher (p <0.05) compared to 55, 56 ± 5.83% in 3-year-old HF bull. Meanwhile, the percentage of post-thawing spermatozoa abnormalities in the three age groups were 4.33 ± 1.96%, 5.89 ± 1.90%, and 5.33 ± 1.41%, not significantly different (p> 0.05) respectively. It concluded that the best quality of post-thawing HF semen based on the percentage of viability, motility, and morphologic abnormality was collected from 5-8 years old bull. Nevertheless, spermatozoa from the three age goups still meet the Indonesia standard quality of frozen semen for artificial insemination.

Abstract:

Protein and lipid molecules in seminal plasma (SP) collected from fertile bulls were investigated. Semen was collected from 10 bulls (2 ejaculates each) and examined for standard semen analysis. Raw SP was recovered by centrifugation and total protein (TP) concentration was determined using a refractometer. Raw SP was desalted using a Sephadex G-25 desalting column then both raw and desalted SP was subjected to SDS-PAGE. Neutral lipids and phospholipids of raw and desalted SP were separated by thin-layer chromatography (TLC). The results revealed that, all bulls had normal semen characteristics and TP concentration in SP ranged from 7.0 to 10.4 g/dL except bull No. 6 had a relatively low concentration of 4.9 to 6.8 g/dL. Neither proteins nor lipids species were different between raw and desalted SP. Seventeen proteins were detected ranging from 8.5 to 185.8 kDa, and those of 12, 13.5, 15, 21, 23 and 38 kDa were predominant. Notably, proteins of 10, 17.5, 19, 21, 80 and 185.8 kDa might be new candidates of SP proteins (SPPs). The detected neutral lipid spots corresponded to cholesterol, 1,2-dimyristoyl glycerol, 1,2-dioleoyloglycerol, 1,3-dimyristoyl glycerol and 1,3-dioleoyloglycerol. The detected phospholipids spots corresponded to non-migrating phospholipids, sphingomyelin (SM), phosphatidylcholine (PC), phosphatidylserine (PS), phosphatidylinositol (PI), phosphatidylethanolamine (PE), cerebroside and polyglycerol phosphatide. Cholesterol represents the major molecule of neutral lipids, whereas SM, PC, PI and PE represent the major phospholipids. Noteworthy, there were 2 species of diacylglycerol (DAG) and 3 species of PI in bovine SP. In conclusion, this study gave a general picture of SP protein and lipid species in fertile bull semen, which might serve as fundamental knowledge for either semen analysis or prediction of male fertility.

In 1983 a linear assessment evaluation scheme was introduced in order to describe the conformation of animals in a more objective way. In conjunction with the Holstein Friesian Society it was agreed to score 16 main traits in the assessment scheme. The MMB also included a seventeenth trail, Beef Shape. The linear assessment scores are analysed by Best Linear Unbiased Prediction to provide sire evaluations on the bulls in the progeny testing scheme. The purpose of this study was to evaluate the environmental and genetic parameters for the traits assessed in the scheme during the first two years.

Abstract:

Bacterial contamination of semen is an important factor connected to the health status of bulls that may significantly affect semen quality for artificial insemination. Moreover, some important bovine diseases may be transmitted through semen. Up to now, only a very limited number of complex studies describing the semen microbiome of bulls have been published, as many bacteria are hard to cultivate using traditional techniques. The 16S rRNA high-throughput sequencing strategy allows for the reliable identification of bacterial profiles of bovine semen together with the detection of noncultivable bacterial species. Fresh samples from Holstein Friesian breeding bulls (n = 55) were examined for the natural variability in the present bacteria. Semen doses were selected randomly from Slovak Biological Services in Nitra, Slovak Republic. The most predominant phyla within the whole dataset were Firmicutes (31%), Proteobacteria (22%), Fusobacteria (18%), Actinobacteria (13%) and Bacteroidetes (12%). Samples of semen were divided into two separate clusters according to their microbiome compositions using a cording partition around a medoids analysis. Microbiomes of the first cluster (CL1) of samples (n = 20) were based on Actinobacteria (CL1 average = 25%; CL = 28%) and Firmicutes (CL1 = 38%; CL2 = 27%), while the second cluster (CL2; n = 35) contained samples characterized by a high prevalence of Fusobacteria (CL1 = 4%; CL2 = 26%). Some important indicator microbial groups were differentially distributed between the clusters.

The study was conducted to find out the effect of beef cattle diet on the performance of upgraded Holstein Friesian bulls at BAPARD cattle farm in Bangladesh. For this purpose, twelve Local x Holstein-Friesian upgraded bulls (L×F) of average 20 months of age and 213 kg live weight were divided into three equal groups. Three different diets such as (i) a mixed concentrate ration (T1), (ii) mixed concentrate ration and UMS at a ratio of 1:1 on DM basis (T2) and (iii) green Grass based ration without concentrate and UMS. The results found that the average daily live weight gains of three groups was 350g, 330g and 340g respectively, which were not differ significantly (P<0.05). Daily DM intake was significantly higher in T3 but the digestibility found lower than other treatments. In case of feed conversion ratio (FCR), the highest FCR was found in T1 (2.96) but cost of per kg live weight gain was the lowest in T3 (BDT 90) compared to T1 (BDT 140) and T2 (BDT 142). Therefore, considering the FCR and cost of per unit beef production, a beef diet of green grass might be the appropriate diet for the floodplains area for Local x Holstein-Friesian upgraded bulls.

Abstract The effectiveness of a program aimed at eradicating carriers of the recessive disorder Complex Vertebral Malformation (CVM) from the population of Holstein-Friesian bulls is reported. Among 1823 bulls, 1268 young and 555 proven bulls were examined. Three hundred and three bulls appeared to be CVM carriers (16.62%). The highest number of carriers occurred in the sons of a CVM sire, 55.51% and 61.90%, for proven and young bulls, respectively. This very high incidence of CVM carriers forced us to implement a strategy of screening young bulls offered by individual breeders to insemination centers. In effect, the number of CVM carriers dramatically dropped among proven bulls born in 2004 and disappeared in bulls born in 2006.

Abstract The material for the study consisted of 80 samples taken from the longissimus lumborum (LL) and semitendinosus (ST) muscles of young bulls of five breeds (8 samples of each muscle per breed), including three native breeds included in the genetic resources conservation programme, i.e. Polish Red, White-Backed and Polish Black-and-White, which together with the Simmental and Polish Holstein-Friesian breeds. The content of the elements (K, Na, Mg, Ca, Zn, Fe, Mn, and Cu) analysed in the meat of the young bulls (fattened in a semi-intensive system on fodder from permanent grassland) was found to depend (in varying degrees) on the breed of cattle. The greatest differences (P<0.01 and P<0.05) were noted between the Polish Holstein-Friesians (PHF) and the remaining breeds, mainly in the content of Mg, Ca, Zn and Mn. The results obtained in the four other breeds for most of the macro- and microelements were more uniform, with the highest content noted in the muscles of the young bulls of the native breeds.

Abstract The aim of the study was to find out whether the single nucleotide polymorphism (SNP) within arylsulfatase D (ARSD) gene is associated with kinematic parameters of sperm motility in Holstein- Friesian bulls. 367 Holstein-Friesian bulls kept in one AI center were included in the study. Point mutation C/T at position 139037255 on chromosome X (rs42207167) was identified by PCR-RFLP method (Pflm I). Significant associations were found between ARSD genotypes and CASA-derived sperm motility parameters: average TM (Total Motility), average VSL (Straight Velocity), average VCL (Curvilinear Velocity) and for fraction of sperms showing progressive motility (a) of sperms (VSLa, VCLa and BCFa -Beat Cross Frequency). Most significant differences were observed between alternative homozygotes (CC vs TT). Our results suggest new role of arylsulfatase D gene as being involved in sperm motility.

Abstract:

Oestradiol 17β (Compudose-365 ) is widely used as a growth promoter in steers and the daily gain response is well known. However, for bull beef production the efficiency of the hormone implant is not so well researched, particularly in Great Britain, where there is not yet a product licence for use in bulls. Work in the U.S.A. has shown that Oestradiol 17β implants in bulls stimulate daily gain and improve carcass shape, but at the same time increasing subcutaneous fat levels (Johnson et al, 1984). The trial described here was designed to study the effect of Oestradiol 17β under a range of farm conditions in Great Britain.Sixteen groups of bulls on 14 farms, totalling 450 bulls, were selected. Fourteen of the groups were wholly British Friesian, the remainder Friesian/Holstein or Limousin cross. The bulls were weighed at 3-4 months of age and paired by weight. One of each pair was implanted subcutaneously in the ear with a silastic rubber implant containing 45 mg Oestradiol 17β (Compudose-365, Elanco Products Ltd.). The bulls were weighed after three and six months (mean 108 and 180 days respectively), and about half were weighed within four days of slaughter (mean 222 days).

Abstract:

Silk sericin plays a protective role in a variety of mammalian cells during cryopreservation. This study aimed to determine the effects of sericin supplementation to a freezing extender on sperm quality and lipid peroxidation in dairy bull sperm cryopreservation. Each semen sample of five Holstein-Friesian crossbred bulls was divided into four aliquots and diluted in a tris-egg yolk extender supplemented with different concentrations of sericin [0%, 0.25%, 0.5%, and 1.0% (wt/vol)]. Sperm motility (CASA), viability, acrosome integrity, mitochondrial membrane potential (fluorescent staining) and lipid peroxidation (malondialdehyde – MDA test) were analysed. The results show that the 0.25% and 0.5% sericin groups had the highest total sperm motility (P < 0.05). Sperm viability, acrosome integrity, and mitochondrial function were higher in the group supplemented with 0.25% sericin compared to the control and 1.0% (P < 0.05). Sericin supplementation with 0.25% and 0.5% significantly decreased MDA concentrations compared with the control (P < 0.05). In conclusion, supplementation of the semen freezing extender with sericin at the concentration of 0.25% significantly improved the post-thaw semen quality and reduced lipid peroxidation in Holstein-Friesian crossbred bulls.

Abstract:

Whilst it is well recognised that there is considerable within-breed variation in growth performance and body composition of cattle it is unusual for sire origin to be taken into account when designing nutritional studies. In planning an experiment on the effects of plane of nutrition and slaughter weight on the body composition and energy metabolism of Friesian steers it was recognised that the increased incidence of the Holstein gene pool in many AI bulls could have serious implications for interpretation of the results. Hence AI bulls of low Holstein content were identified and an attempt was made to obtain calves from a small number of bulls of uniform conformation.

Abstract. Title of the paper: Effect of feeding on the composition of the intramuscular fat in longissimus muscle and different fatty tissues of Hungarian Grey and Holstein Friesian bulls. 1. Fatty acid profile The aim of this study was to analyse the effect of nutrition, genotype and nutrition x genotype interaction on the fatty acid composition of intramuscular fat from longissimus dorsi muscle and different fat deposits using Hungarian Grey cattle bulls (HG) in comparison to Holstein Friesian bulls (HF) kept under extensive and intensive conditions. The extensive group was kept on pasture and was fed a concentrate supplemented with linseed meal in the last month of the trial. The extensive diet influenced the linoleic and linolenic acid ratio and the CLA content of longissimus muscle more advantageous concerning human nutrition. The meat from HG contained more CLA and less n-6 fatty acids also in case of the intensive diet than that of HF bulls. In the fat deposits from HF the PUFA mainly the linoleic acid was in a significant higher proportion available, however in the fat deposits of HG was the percentage of linol- and linolenic acid favourable. The extensive nutrition resulted in a lower linoleic acid and a higher linolenic acid content in both breeds and all three fat deposits. The PUFA content in the fat samples was altered contrary in both analysed breeds because of the different diet. In case of the extensive UG was the PUFA higher in all three fat deposits. In conclusion, the fatty acid composition of beef can be modified favourably by extensive feeding and concentrate which is rich in unsaturated fatty acids, however the beef of Hungarian Grey has a more wholesome influence on human health, than that of Holstein-Friesian bulls.

Abstract:

Recent years have seen increasing interest in the conservation and use of native breeds of livestock raised in traditional farming systems. The experience of many European countries shows that promotion of raw materials and products derived from these breeds through a labelling system has a beneficial effect on the sustainable development of rural areas, contributes to preservation of the cultural heritage of the countryside, and increases the population of the breeds. As yet no beef produced in Poland has been included on the European list of traditional and regional products. For this reason we conducted a study to evaluate selected physicochemical properties of the meat of young bulls of three native breeds, Polish Red, White-Backed and Polish Black-and- White, compared with the meat of young Simmental and Polish Holstein-Friesian bulls, during a 14-day ageing of vacuum-packed meat. The following parameters were measured in m. longissimus lumborum (MLL) taken from half carcasses of 50 young bulls (10 from each breed): pH, electrical conductivity (45 min., 24 h, 2, 7 and 14 days post mortem), colour (according to CIE L*a*b*), shear force and energy. The water-holding capacity of the meat (drip loss, cooking loss and free water by the Grau-Hamm method), TBARS value (on days 2, 7 and 14) and content of haem pigments were determined as well. The physicochemical parameters of the MLL muscle obtained from the native Polish breeds of bulls (Polish Red, White-Backed and Polish Black-and-White) had intermediate values between those of Polish Holstein- Friesian (dairy type) and Simmental (dual-purpose) cattle. No qualitative deviations, such as those associated with DFD syndrome (pH 48 h in the range of 5.51-5.72), were found in any of the samples, which indicates that the raw material is well suited to the production of beef for culinary purposes. The breed of cattle was found to significantly influence the water-holding capacity parameters. The highest (P < 0.001) drip loss was reported on the 14th day post mortem for the MLL of young bulls of the Simmental (6.89%) and Polish Red breeds (6.47%). The highest cooking loss was found on the 7th day post mortem in the MLL of young bulls of the Polish Holstein-Friesian (30.66%) and Simmental breeds (30.92%). Significantly (P < 0.01) the least favourable water-holding capacity (the largest amount of free water) was shown by the muscle of young bulls of the Simmental breed on the 2nd day post mortem (75.31 mg) and the Polish Red breed on the 7th and 14th days post mortem (67.42 mg and 60.36 mg, respectively). On the 2nd and 7th days post mortem, the most tender MLL muscle was found (according to WBSF shear force) in the Polish Holstein-Friesian (76.8 N and 69.3 N) and Polish Black-and-White breeds (89.5 N and 59.1 N). On the last, 14th day of ageing, the instrumental WBSF shear force for the breeds evaluated was definitely more homogeneous and did not differ significantly (shear force in the range of 56.3-65.7 N; P > 0.05). Compared to the muscle of native breeds, that of the Polish Holstein-Friesians showed significantly lower haem pigments (on average 35 ppm less; P < 0.01) and a lower proportion of redness (a*) (P < 0.01) on the 2nd and 7th days post mortem. The MLL muscle of young bulls of the Polish Red breed had the lowest (P < 0.01) percentage content of yellowness (b*) during the whole ageing period. Significantly (P < 0.01) lower oxidative stability (higher TBARS value) was found in the meat from young bulls of the Polish Holstein-Friesian breed (on the 2nd and 7th days post mortem) and the White-Backed breed (on the 14th day) compared to all other breeds analysed. In general, the ageing time had a positive influence on the muscle quality, as the determinants of the visual and sensory attractiveness of the meat, which are also important in the meat industry, remained stable (pH), improved (colour and water-holding capacity G-H) or became more similar among the breeds (tenderness assessed on the basis of shear force, cooking loss)....

Abstract:

The aim of this study was to compare Aberdeen Angus (AA) and Holstein Friesian (HF) bulls in Turkey based on fattening performance, carcass properties, and production costs. In the trial, 105 AA and 105 HF 10- to 12-month-old bulls with a mean initial bodyweight (IBW) of 302 kg were used. The bulls were distributed into 14 paddocks in groups of 15 based on their IBW at an open-shed facility in İzmir. The bulls were fed different rations for the grower and finisher periods for 90 days each, but otherwise were kept under similar conditions. At the end of the finishing period, the animals were slaughtered and carcass characteristics, organ weights, quality of meat, and meat production costs were evaluated. In terms of fattening performance, the AA bulls were superior to the HF bulls. The ultimate pH of the Longissimus dorsi in the AA bulls was lower than in the HF bulls and the sensory characteristics of the AA bulls were higher. Production costs were higher for the AA bulls, but so too were income over feed costs (IOFC), making the AA bulls more profitable. Thus, it might be concluded that beef breed bulls that mature quickly, such as AA, are more advantageous for meat production in Turkey than HF bulls, which are a by-product of the dairy industry.

Abstract:

The quality of beef is determined, among others, by factors such as breed, age and sex of slaughtered animals and fattening intensity. The aim of the study was to assess carcass quality of young cattle purchased by a selected domestic meat processing plant. The study included a group of 300 bulls and 300 heifers with selected genotypes (Limousine breed; crossbreds – Charolaise, Limousine, Simental × Polish Holstein-Friesian; Polish Holstein-Friesian breed). The following were determined for each animal: body weight before slaughter (kg), hot carcass weight (kg), hot carcass quality index (%), carcass conformation class and carcass fatness class according to the EUROP system. The mean body weight of slaughtered animals was found to be 650 kg. Carcass yield of the assessed young cattle was on average 54%. Carcasses of bulls (non-castrated males) were on aver- age 90 kg heavier and had 3 pp. higher carcass yield than carcasses of uncalved females (P < 0.05). The conformation classes of the EUROP system showed that almost 48% of the carcasses of young Limousine bulls reached the highest classes, i.e. E− and U. Limousine bulls (57.2%) had the highest carcass yield among the determined genotypic groups. The desired lowest degree of fatness was found in carcasses of bulls of all genotypes (an average of 2.9 points).

Abstract:

The intensive breeding work of Holstein-Friesian cattle has led to the decrease in the diversity within the population and to inbreeding depression, which may impair its functional traits. In addition, as shown by the research, production traits are negatively correlated with functional traits such as reproduction, health, and longevity, which have a very strong impact on the profit of dairy farms. The aim of this study was to compare milk yield traits of hybrids obtained by crossbreeding of Polish Holstein Friesian (PHF) cows and Swedish Red (SRB) bulls with values obtained for pure PHF cows. For the study, 100 primiparous cows were selected and divided into two groups. The experimental group consisted of 50 crossbreds (PHF×SRB), while the control group consisted of 50 purebred PHF cows. The study showed a higher content of milk components (fat by 11.78 %, protein by 9.06 %, dry matter by 5.75 %) in PHF×SRB, as compared to PHF. A lower level of SCC (by 38.94 %) has also been shown in hybrids, which indicates their higher resistance to udder diseases. The experiment demonstrated a highly significant impact of heterosis on performance parameters and technological quality of milk in F1 generation obtained as a result of crossbreeding between PHF cows and SRB bulls.
