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:
In dairy cattle, treatment with exogenous growth hormone (GH) affects growth and function of mammary gland. The actions of GH are mediated via interaction with GH receptors (GHR). The first step in signal transduction is homodimerization of two GHR molecules by GH. This step is critical since mutation in either GH or GHR can block dimerization and thus target cell activation. However, association between milk related traits and combination of GH and GHR variations are not known. Accordingly, DNA genotypes in the GH and GHR genes were investigated for association with milk, fat and protein lactation yields in Holsteins. The marker data were obtained on 873 progeny tested bulls by using PCR-RFLP and PCR-SSCP analysis. There were five markers in GH and three in GHR. Estimated breeding values (EBVs) were obtained from Canadian Dairy Network for milk, fat, and protein lactation yields for the 873 genotyped bulls.
There was significant difference among GH6.1 alleles (C-to-G transversion at position 2141) for the milk yield (P < 0.05) and protein yield (p < 0.05). There were significant differences in GHR AluI (A-to-T transversion at -1182) for milk (p < 0.05) and fat (p < 0.05), and GHR StuI (C-to-T transversion at -232) for fat (p < 0.0001) and protein (p < 0.05). Allele frequencies for GH6.1 (C), GHR AluI (A) and GHR StuI (C) alleles in bulls genotyped were 0.95, 0.63 and 0.95, respectively. Bulls with GH6.1 (C/G) genotype had higher milk EBV (p < 0.05) compared to C/C bulls. Bulls with GHR AluI (A/A) genotype had higher milk EBV (p < 0.01) and fat EBVs (p < 0.05). Bulls with StuI (C/C) genotype had higher fat EBV (p < 0.0001) and protein EBV (p < 0.05) compared to StuI (C/T). This study indicates that the combination of GH and GHR markers could serve as a tool to aid in selection for improving milk, fat, and protein production.
