Abstract:

The aim of our study was to examine how different gelatin concentrations affect ram semens viability in liquid storage at 5 oC for five days. Our hypothesis was if we add gelatin to the semen extender, than the viability of ram semen will be better in the extenders containing gelatin, than the control. We used two different semen extenders:1.5% UHT milk and 1.5% UHT milk + 5% egg yolk. We added 0; 0.5; 1.0; 1.5; 2.0% Dr. Oetker gelatin to the semen extenders. We stored the semen for five days at 5 oC and in every 24 hour we made sampling.We stained the smears with Kovács-Foote staining and evaluated them with light-microscope. We categorized the cells in five groups like: live and intact cells, live cells with injured acrosome, dead cells, live head with dead tail and live tail with dead head. We used one-way analysis of variance (ANOVA) to assign how gelatin concentration affects the number of the categorized cells. On the fifth day, the viability was the best in the following semen extenders: 1.5% fat UHT milk + 1.0% gelatin and 1.5% fat UHT milk + 1.5% gelatin, but it was not significant (p>0.05).

Abstract:

Penelitian penggunaan slag semen pada campuran beton sebagai cementious telah dimulai sejak tahun 1774. Saat ini di negara-negara maju slag semen telah dimanfaatkan pada setiap campuran beton, bahkan persentasenya mencapai 30% dari cementious, hal ini dapat dilihat dari produksi slag semen yang terus meningkat dari tahun ke tahun. Pembuatan beton dengan menggunakan slag sement sebagai campuran agregat halus untuk subtitusi terhadap semen yang selanjutnya dilakukan pengujian terhadap benda uji beton untuk mengetahui seberapa besar pengaruhnya terhadap nilai kuat tekan pada beton, serta bertujuan juga untuk mendapatkan campuran bahan beton dengan biaya yang lebih efisien dibandingkan beton non-slag. Kuat tekan Beton akan mengidentifikasi mutu dari sebuah konstruksi, semakin tinggi kekuatan struktur yang direncanakan , maka semakin tinggi pula mutu beton yang harus di hasilkan. Beberapa faktor yang mempengaruhi kuat tekan beton, yaitu faktor air semen (w/c), jumlah air, jumlah dan kualitas semen, kualitas agregat, umur beton, serta perawatan beton. Apabila w/c tidak sesuai dengan beton yang direncanakan maka beton akan mengalami perubahan kekuatan. Hubungan antara kuat tekan beton dengan nilai w/c berbanding terbalik, kuat tekan akan menjadi tinggi apabila angka w/c kecil dan sebaliknya kuat tekan akan rendah apabila w/c makin besar. Hasil penelitian ini menunjukan bahwa perbandingan komposisi untuk memperoleh mutu yang sama didapatkan hasil pada beton slag ada penambahan air 7 liter/m³ terhadap non-slag, dan mengurangi sementious sebesar 2 kg/m³, serta slag semen memberikan kontribusi terhadap kuat tekan lebih besar dari pada beton non-slag sebesar 4,3%, akan tetapi dalam mencapai hal itu, slag semen membutuhkan air yang lebih banyak, sedangkan dari segi biaya, dibandingkan beton non-slag, slag semen dapat menekan biaya sebesar Rp 15.354,00/m3.

Abstract:

Sperm cryopreservation is the best technology for long-term storage of the semen. However, the damage of boar spermatozoa by cryopreservation is more severe than in other animal species and a standardized freezing protocol for efficient cryopreservation has not been established yet. Semen quality and freezability vary greatly between breeds as well as between individual boars and even the season. Boar spermatozoa are sensitive to low temperatures; they sustain damage and a high rate of mortality and freezing/thawing the boar semen may strongly impair the sperm function and decrease the semen quality. The freezability of boar semen can be influenced by a cryopreservation procedure, and also by using various additives to freezing and thawing extenders such as antioxidants. In order to obtain acceptable results after thawing the boar semen, it is necessary to combine an optimal amount of additives (glycerol, egg yolk, sugars, antioxidants), cooling and warming velocities.

Abstract:

This study was conducted to examine testosterone concentrations its relationship with the scrotal circumference and physical characteristics of semen in aceh bulls. Semen samples were collected weekly from jugular vein of three aceh bulls aged 4-5 years old for 10 weeks. Testosterone concentration was measured by enzyme-linked immunosorbent assay (ELISA) method. Semens were collected by using artificial vagina and evaluated for physical characteristics namely ejaculatory volume, pH, and sperm motility, concentration, and abnormalities. Data were analyzed using correlation-regresion test. Testosterone concentrations showed a positive correlation with scrotal circumference (r = 0.799), number of sperm (r = 0.703), sperm motility (r = 0.857) and sperm abnormalities (r = -0,877). No correlation, however, was found between testosterone concentrations with semen volume (r = 0.038) and pH (r = 0.418). It can be concluded that testosterone concentrations correlated positively with scrotal circumference, numbers of sperm, sperm of motility and sperm of abnormality.

Abstract:

Semen is a pale whitish fluid secreted by male during ejaculation and containsspermatozoa which are male gametes essential of fertilizing the oocytes which are femalegametes. In a quest to evaluate male’s fertility potential semen is analyzed to look into some ofits characteristics and of the sperms contained within the semen analyzed. Method of collectioninfluences the results of Semen analysis as does the technique of analysis. Spermatozoa areexamined for number (count), shape (morphology) and movement (motility) in order to assesstheir quality. Non sperm cells, volume, Fructose level, pH, liquefaction are also checked asa part of routine analysis. Objectives: To describe the pattern of semen parameters in subfertilemales. To look into frequency and distribution of abnormal semen parameters in a groupof Pakistani males in Lahore. Methods: In this Retrospective, cross sectional, observationalstudy all males undergoing for evaluation and treatment for sub-fertility at a private AssistedReproductive Technology clinic in Lahore, Pakistan were included. Approval of the IRB wassought and data collection instrument was a specially designed Performa which was validatedby the biostatistician of LIFE research cell. Data was extracted from the files of LIFE (LahoreInstitute of Fertility and Endocrinology) and entered in SPSS version 15. Sampling techniquewas non-probability, consecutive. Semen analysis was done by methods defined by the WHO(World Health Organization). Results: Of total patient (n=679) 92.2% (626) males passed sampleat LIFE (Lahore institute of fertility and endocrinology) and (7.8%) 53 brought sample fromhome. Of the males who passed sample at LIFE (78.8%) 535 collected semen by masturbation,(11.9%) 81 by coitus; the source of sample of (9.3%) 63 males was not known. As 2-6 ml semenwas consider to be normal by WHO criteria, (80.6%) 547 males were in normal range (14.1%)96 found to be less than 2-6 ml and (5.3%) 36 found to be more than normal range. Accordingto WHO criteria 15 million/ml count is said to be normal, in our research (82.0%) 557 were foundto be normal, in (2.9%) 20 count was found to be less than 15 million/ml and in (5.9%) 40 countwas less than 1 million/ml. In (9.1%) 62 counts was found to be abnormally low. In this research(66.1%) 449 had normal sperm motility, (21.8%) 148 had less than 40% and abnormally lowsperm motility was found in (12.1%) 82 males. Conclusion: The results of the single semenanalysis are of limited utility and no decision should be taken on the bases of these results interm of diagnosis and treatment strategies.

Abstract:

Background: Male infertility is a frequent reproductive health problem in the world. It is usually related to abnormal spermproduction or function and these abnormalities can occur anywhere in the production of sperm including hormonal regulation, storage andtransport of sperm. Various factors are known to be responsible for seminal fluid abnormalities. Usually the first step in evaluating for maleinfertility is semen analysis. Setting: The study was conducted at Muhimbili National Hospital mainly in the department of Pathology laboratory,cytology unit. Study design: The study was a hospital based cross-sectional type. Objective: To determine semen pH in patients presenting withinfertility complains and relate how pH of seminal fluid and other semen parameters influence each other. Material and methods: Beforesemen collection, patients were instructed to abstain from sexual intercourse for a minimum of 48 hours to 7 days and collect semen bymasturbation and transport it to the laboratory through shirt pocket. Semen was to reach the laboratory for examination in not more than onehour from time of collection. Semen was examined macroscopically for volume, colour, viscosity and pH by using a pH meter (Consort C830)followed by microscopic examination which included motility of spermatozoa and sperm count by using Neuber counting chamber. The smearwas made on glass slides, fixed in 95% ethyl alcohol for 30 minutes then stained by using Papanicolaou’s staining technique and then analyzedmicroscopically for morphological examination. Results: In the analysis of the influence of semen parameters on semen pH, there wasdecrease in seminal fluid pH with age whereby as age increased the pH of seminal fluid decreased.. The general trend observed was that thepH of seminal fluid tended to decrease with an increase in the days of abstinence. pH tended to decrease with an increase of seminal fluidvolume. The pH of seminal fluid also increased with an increase in viscosity (Hyperviscosity >Hypoviscosity). The pH of seminal fluid in patientswith less than 50% forward progressive movement of spermatozoa was higher when compared to those with more than 50% forwardprogressive movement. pH had an influence on the motility of spermatozoa. Conclusions and recommendation: pH and other parameterstended to have an influence each other during seminal analysis in our study. There is a variation of pH in different parts of the World according tothe studies done. It is recommended that pH should be included during seminal analysis because our study has shown that it affects most of theseminal fluid parameters in and contribute to the problem of infertility.

Abstract:

Objective: The objective of this study was to study the semen parameters and its relation to hormonal status in infertile men. Study Design: Cross sectional study. Period: March 2015 to April 2017. Setting: Jinnah Hospital Fertility Centre; Department of Obstetrics and Gynecology, Lahore. Method: A total of 70 infertile men were included in this study. Semen samples for semen analysis and serum for hormonal analysis were obtained and further tests were performed. Results: The results of our study show that 28.57% were Normospermic, 18.56% were azoospermic and 52.85% were Oligospermic. In Oligospermic and azoospermic patients significant low levels of testosterone and prolactin were noticed. The results indicate that along with semen parameters hormonal levels should also be assessed to diagnose the underlying cause of infertility. Conclusion: It is concluded from our study that both quality of semen and hormonal levels cause infertility in men. Therefore the patients should be properly investigated and should be treated accordingly to the underlying abnormality. This is a regional study and further studies should be conducted to have a conclusive evidence at national level.

Abstract:

The aim of the present study was the modification and evaluation of three different semen extenders for cockatiel semen in order to achieve a long survival time for transport, examination purpose and for potential cryopreservation, respectively. Therefore, individual and pooled semen samples of 30 cockatiels (Nymphicus hollandicus) were investigated for pH and osmolality values and subsequently pH and osmolality values of the semen extenders were adjusted to those values in the semen. Pooled semen samples were then partitioned into four equal parts and diluted with the three different semen extenders in 1:4 and 1:8 dilution. 1 % glucose-Ringer’s solution was used as control, respectively. A total of 64 incremental diluted semen samples were obtained for investigation. Each dilution was investigated regarding sperm motility immediately after dilution and another four times every 30 minutes. Sperm viability was evaluated 0 and 120 minutes after dilution via eosin B-stain on the diluted semen samples and in pure semen samples. Additionally, the fluorescence stain SYBR® Green/propidium iodide was used to assess sperm viability. The results indicate that cockatiel spermatozoa are highly sensitive to variations in pH and osmolality, requiring adjustment of commercial diluents to pH = 7.42 and osmolality = 300 mOsm/kg. Modified Lake diluent maintained higher viability and motility than other diluents tested. Sperm morphology was indicated to be least adversely affected by modified Lake diluent in 1:4 concentration compared to other semen extenders and concentrations used.

Abstract:

Bata ringan dalam pelaksanaannya dilakukan pemasangan dengan menggunakan perekat bata ringan, namun di berbagai tempat khususnya di kabupaten Sumenep pemasangan bata ringan menggunakan semen biasa atau yang banyak beredar dipasaran seperti semen PPC. Berdasarkan perbedaan tersebut penelitian ini akan membandingkan syarat mutu fisika antara semen PPC dengan semen mortar (lem bata ringan) yang ada di kabupaten Sumenep. Tujuan penelitian membandingkan syarat mutu fisika semen PPC dengan semen mortar (lem bata ringan) yaitu untuk mengetahui waktu pengikatan, penurunan atau pengerasan dan kuat tekan antara semen PPC dan semen mortar (lem bata ringan). Penelitian ini merupakan penelitian eksperimental. Benda uji untuk waktu pengikatan dan pengerasan semen baik semen PPC dan semen mortar (lem bata ringan) dengan membuat bola pasta, sedangkan benda uji untuk kuat tekan dengan membuat benda uji berbentuk kubus 5 x 5 x 5 cm. Semen PPC menunjukkan terjadi penurunan pada menit 105 sebesar 4.1 mm dan waktu pengikatan awal terjadi pada menit 139 dengan penetrasi 25 mm. Semen PPC memenuhi syarat fisika SNI. Semen mortar (lem bata ringan) selama 150 menit tidak terjadi penurunan dan pengerasan sama sekali, sehingga waktu pengikatan awal semen mortar (lem bata ringan) memenuhi syarat SNI. Kuat tekan semen PPC mempunyai kuat tekan rata – rata sebesar 26.33 MPa, sedangkan semen mortar (lem bata ringan) sebesar 4 MPa. Kuat tekan semen PPC memenuhi syarat SNI, sedangkan semen mortar (lem bata ringan) tidak memenuhi syarat SNI. Semen mortar (lem bata ringan) lebih tepat digunakan dalam pelaksanaan pemasangan bata ringan dan semen PPC lebih kuat jika dibandingkan dengan semen mortar (lem bata ringan).

Abstract:

Semen quality traits such as semen volume, sperm motility, sperm concentration, pH, and color are very important, since they can determine the fertility potential of the semen. The objective of this study was to compare the semen quality traits of Thai Native chickens (Pradu Hang Dam and Chee) producing high and low semen volume. Semen was collected from 24 roosters (12 reps) and divided into two groups of roosters producing high semen volume (>0.3 mL) and those producing a low amount of semen (<0.3 mL). Fresh semen quality parameters (semen volume, sperm motility, viability, concentration, and pH) were measured and compared between groups. It was found that semen volume showed a positive correlation with sperm concentration, mass movement, motility, viability, and pH of fresh semen. There was no significant difference in fresh semen parameters between Pradu Hang Dam and Chee roosters with either high or low ejaculate semen, except for sperm concentration. Sperm concentration was significantly higher in Chee compared with Pradu Hang Dam in both high and low ejaculate semen. The semen quality parameters between groups of chickens producing high and low ejaculate semen were significantly different except for sperm viability. In conclusion, it was found that chickens producing high volumes of semen have better sperm quality than those producing a low semen volume. Therefore, these results provide a possible consideration that the amount of semen production among chickens can be used as a tool in selecting Thai native roosters for breeding.

Abstract:

One of the important and underappreciated reproductive health problems in developing countries is the high rate of infertility and childlessness. A cross-sectional type of descriptive study was conducted to evaluate the male fertility status by the conventional semen analysis. This study was conducted in which 100 men with age ranged from 20 to 45 years of a primary and secondary infertile couple of more than one year, in the Infertility OPD of Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka during October 2012 to March 2013. They were divided into two groups depending on the results of their semen analysis: 35 with abnormal semen and 65 with normal semen profile. The mean (±SD) age was 34.0±4.7 years in patients with abnormal semen and 33.9±5.6 years in patients with normal semen. Nearly one-third (31.42%) of the patients was a farmer in abnormal semen and 7.7% in normal semen. The majority (62.85%) of the abnormal semen patients worked in hot environments, STD was found 20.0% in patients with abnormal semen and 3.1% in patients with normal semen, mumps observed 8.6% in abnormal semen and 3.1% in normal semen patients. Surgical history was found 11.4% in abnormal semen and 1.5% in normal semen patients. Positive family history of infertility was found in 8.6% of abnormal semen patients but no positive family history of infertility was found in normal semen patients. Varicocele was found 25.7% in patients with abnormal semen and 21.5% in patients with normal semen. Primary subfertility was 91.4% in abnormal semen patients and 58.5% in normal semen patients. Farmer, hot working environment, STD, surgical history, positive family history, primary subfertility were significantly (p<0.05) higher in patients with abnormal semen. The highest number of patients were oligospermic (51.4) followed by azoospermia 22.9%, asthenozoospermia 17.1%, teratozoospermia 5.7% and aspermia 2.9%.

Abstract:

Despite the advances in reproductive technology, there is still a considerable number of low sperm quality cases in stallions. Recent studies in humans have detected several seminal microflora–spermatozoa associations behind some idiopathic infertility cases. However, no studies are available on horses, and there is limited information on the microflora present in stallion ejaculates. Accordingly, the objective of this study was to examine associations to the presence of bacteria families with five sperm quality parameters: concentration, total number of spermatozoa, total and progressive motility, and DNA fragmentation. Samples were cryopreserved after their extraction. High-speed homogenization using grinding media was performed for cell disruption. Family identification was performed via 16S rRNA sequencing. Bacterial families were only considered if the relative abundance was higher than 1%. Only two families appeared to have a correlation with two sperm quality parameters. Peptoniphilaceae correlated positively with total sperm motility, whereas Clostridiales Incertae Sedis XI correlated negatively with progressive motility. No significant differences were found for the rest of the parameters. In conclusion, the seminal microbiome may affect spermatozoa activity. Our findings are based on statistical associations; thus, further studies are needed to understand the internal interactions between seminal flora and cells.

Abstract:

Semen quantity and quality are affected by transportation and frequent semen collection in ram when they are transported from nucleus flock to target farms for in situ artificial insemination (AI) of ewes with fresh semen. The current study was designed to introduce the best method of fresh semen preservation for fixed time AI in Karakul sheep. The adult Karakul ewes were allocated to 6 groups (30 ewes in each group) during the breeding season and each group was inseminated with one of the following treatments, viz. fresh semen without extender, fresh semen diluted with Tris-egg yolk or milk, cooled semen (stored at 10°C for 8 h) without extender, and cooled semen diluted with Tris-egg yolk or milk. Lambing and fecundity rates were the highest when ewe was inseminated with undiluted fresh semen (71.42 and 85.71%, respectively). These reproductive indices in ewes, which were inseminated with diluted fresh semen or undiluted cooled semen were significantly lower than those recorded in inseminated ewes with undiluted fresh semen. The type of extender and storage of diluted semen at 10°C for 8 h did not significantly affect lambing rate of Karakul ewe. Results suggested that use of undiluted fresh semen and diluted fresh semen in milk or Tris-egg yolk extenders are preferable for fixed time AI in ewes of genetic improvement center and Karakul sheep flocks located near to this center, respectively.

Abstract:

Semen merupakan bahan dasar utama konstruksi bangunan, sehingga menjadikan semen sebagai komoditi yang strategis. Semen PCC (Portland Composite Cement) merupakan jenis semen varian baru yang mempunyai karakteristik mirip dengan semen Portland, tetapi semen jenis ini mempunyai kualitas yang lebih baik, ramah lingkungan dan mempunyai harga yang lebih ekonomis. Penambahan limestone sebagai aditif berfungsi meningkatkan kuat tekan pada semen. Tujuan penelitian ini adalah mengetahui pengaruh penambahan limestone dengan berbagai variasi terhadap kuat tekan dan menentukan massa limestone yang dapat memberikan kuat tekan maksimum pada semen Portland komposit. Pembuatan semen Portland komposit dilakukan dengan penambahan limestone sebagai aditif. Variasi limestone yang ditambakan adalah 0, 5, 10, 15, 20 dan 25%. Pengaruh penambahan limestone dapat diketahui dari hasil uji kehalusan, uji residu, uji komposisi kimia semen dan uji kuat tekan semen. Hasil penelitian menunjukan bahwa semakin besar persentase pemakaian limestone di dalam blended cement maka nilai residu dan nilai kehalusan akan semakin besar namun nilai kuat tekan akan semakin rendah. Kuat tekan semen yang tertinggi yaitu nilai kuat tekan pada umur 2 hari. Komposisi terbaik aditif limestone di dalam blended cement adalah 77% klinker, 15% lime stone, 3% gypsum dan 5% blast furnace slag

Abstract:

Horizontal attenuation total reflection-Fourier transformation infrared spectroscopy (HATR-FT-IR) is used to measure the Mid-IR (MIR) of semen armeniacae amarum and its confusable varieties semen persicae. In order to extrude the difference between semen armeniacae amarum and semen persicae, discrete wavelet transformation (DWT) is used to decompose the MIR of semen armeniacae amarum and semen persicae. Two main scales are selected as the feature extracting space in the DWT domain. According to the distribution of semen armeniacae amarum and semen persicae’s MIR, five feature regions are determined at every spectra band by selecting two scales in the DWT domain. Thus, ten feature parameters form the feature vector. The feature vector is input to the back-propagation artificial neural network (BP-ANN) to train so as to accurately classify the semen armeniacae amarum and semen persicae. 100 couples of MIR are used to train and test the proposed method, where 50 couples of data are used to train samples and other 50 couples of data are used to test samples. Experimental results show that the accurate recognition rate between semen armeniacae amarum and semen persicae is averaged 99% following the proposed method.

Abstract:

Systemic lupus erythematosus (SLE) is a chronic inflammatory disease that can affect fertility. There is currently little information regarding the semen profile of males with SLE. Moreover, there is no consensus on an appropriate period of sexual abstinence for semen analysis and on the use of DNA fragmentation assay, together with multiple semen analyses to document the semen profile in this clinical population. In this case report, multiple semen analyses, with DNA fragmentation assays, were performed for a male with SLE undergoing fertility treatment at our andrology unit. A 4-day period of abstinence improved the semen concentration, total sperm count, total progressive motile sperm, and sperm morphology, with minimal DNA fragmentation. In conclusion, multiple semen analyses obtained after different periods of sexual abstinence, together with DNA fragmentation assays, may be useful to develop a semen profile for patients with SLE, providing information on the optimal abstinence period to yield the best semen quality for subsequent fertility treatment. For patients with fluctuating semen results, concomitant semen cryopreservation should be considered to preserve the better quality semen before starting assisted reproductive technologies if pregnancy is planned in the future.

Tujuan dari penelitian ini adalah menganalisis perbedaan kualitas semen beku yang sudah memiliki sertifikasi Standar Nasional Indonesia (SNI) dengan semen beku yang belum memiliki sertifikasi SNI. Penelitian dilakukan dalam dua tahap, tahap pertama adalah analisis data manajemen produksi semen beku di tempat produksi dengan melihat proses produksi semen beku mulai dari pra produksi dilanjutkan ke proses produksi sampai dengan post produksi, tahap kedua adalah evaluasi kualitas semen beku di laboratorium reproduksi LIPI dengan melihat parameter motilitas, viabilitas, abnormalitas, membran plasma utuh, konsentrasi dan fragmentasi DNA. Data laboratorium dianalisis dengan menggunakan analisis ragam dilanjutkan dengan uji Duncan, sedangkan data manajemen dianalisis dengan menggunakan skoring dan metode deskriptif komparatif. Hasil uji laboratorium menunjukkan bahwa kualitas semen beku yang sudah memiliki SNI lebih baik dibandingkan dengan semen beku yang belum memiliki SNI, analisis manajemen juga menunjukkan korelasi positif dengan hasil uji lab dimana manajemen produksi semen beku yang sudah ber SNI menghasilkan kualitas semen beku yang lebih baik. Dalam kesimpulannya, manajemen produksi semen beku sangat erat kaitannya dengan kualitas semen beku yang dihasilkan oleh produsen. Untuk bisa meningkatkan kualitas, maka diperlukan juga peningkatan manajemen produksinya.

Abstract:

Indonesia has two National Artificial Insemination Centers (AIC) and more than 15 Regional Artificial Insemination Centers (RAIC) spread across several provinces. Bulls in the AIC must have a high libido and produce good quality semen. This study examines the correlation between libido with semen quality and testosterone concentration to determine potential frozen semen production from Bali bulls in South Sulawesi RAIC. Ten Bali bull were used in this study. Semen collection was carried out twice a week with semen evaluation following the RAIC protocol. At the same time, blood samples and libido measurements were carried out from each bull. The frozen semen production potential was calculated by multiplying the semen volume, motility, and sperm concentration. The results showed that the quality of fresh semen and testosterone concentrations did not differ between high and low libido of Bali bulls. Libido has a positive correlation with semen volume (r= 0.52) and sperm motility (r= 0.62), while testosterone concentration has a negative correlation with semen volume (r= -0.65), sperm motility (r= -0.60), and libido (r= -0.48). Bulls with high and low libido have good frozen semen production potential, ranging from 19,755 – 21,640 straws per year. Bali bulls in RAIC have fresh semen quality and testosterone concentrations under normal conditions, with high potential for frozen semen production, although only 60% of Bali cattle have high libido and 40% have low libido.

Abstract:

This study evaluated how semen selection by single layer centrifugation (SLC) with Canicoll affects semen freezability in dogs. A total of eighteen ejaculates, collected from dogs with optimal and suboptimal semen quality (optimal: normal morphology (NM) ≥ 80%, n = 9; suboptimal: NM between 60 and 79%, n = 9), were divided into two aliquots and subjected to standard centrifugation or SLC before cryopreservation. Motility, NM, membrane integrity, mitochondrial membrane potential (MMP), and DNA integrity were improved in fresh samples after SLC, regardless of semen quality, but at the expense of some good quality spermatozoa. After thawing, NM and membrane integrity were improved in SLC-selected semen in both semen qualities. Interestingly, MMP was also higher but only in optimal quality semen. Still, spermatozoa from suboptimal quality semen did not survive freezing to the same extent as spermatozoa from optimal quality semen, even after selecting superior spermatozoa. Semen selection with Canicoll is, therefore, an effective technique to isolate a subpopulation of high-quality spermatozoa and obtain sperm samples of better quality after thawing, but is not sufficient to improve the intrinsic inferior freezability of suboptimal quality semen. So far, eighteen pups were born after insemination with SLC-selected frozen-thawed semen, proving that these selected spermatozoa remain fertile.

Abstract:

Abstract Kinematic parameters of thawed ram semen frozen under field conditions were analysed with the use of two commercial (egg yolk vs egg yolk free) semen extenders in different year-seasonal periods. The semen was collected from Suffolk (n = 2) and Charollais (n = 1) rams kept in private breeding farm on 3 test days (pre-mating, at mating, post mating) during year 2016. Two commercial semen extenders (egg yolk-based BullXcell® or egg yolk-free AndroMed®) were used for semen processing. Processed semen was frozen in 0.25 ml plastic cryostraws using the custom-made portable freezing box for ram semen cryopreservation under field conditions. Thawed semen characteristics were evaluated using computer-assisted semen analysis (CASA) system immediately after thawing and after 2 h of heat incubation (±38°C). Significantly higher total motility (+12.3%), straight line velocity (+5.6 μm s−1), and average-path velocity (+6.9 μm s−1) were detected for the semen processed and cryopreserved using egg yolk-based semen extender. Year-seasonal variation and introducing the ram to service had shown to have a significant effect on the cryopreserved ram spermatozoa. These preliminary results confirmed the feasibility of ram semen processing and cryopreservation under field conditions.

Abstract:

The objective was to analyze the effect of the type of semen, conventional and sexed, on the in vitro production of embryos. A total of 1,285 oocytes and 1,155 oocytes with sexed semen were matured and fertilized with conventional semen, obtaining 1,167 (90.55%) and 1,051 (90.68%) zygotes in fertilization with conventional and sexed semen, respectively (P=0.8411). In in vitro culture, embryo cleavage was evaluated in 769 (67.42%) of zygotes from conventional semen and 540 (55.12%) from zygotes from sexed semen (P=0.8411). There was no statistical difference in both analyzed variables. On day 7, the number of viable embryos produced was evaluated, being 428 (53.55%) conventional embryos and 138 (30.64%) viable embryos from sexed semen (P=0.0001). There was a significant difference, therefore, it obtained better embryonic conversion with conventional semen in relation to sexed semen of Nelore bulls.

Abstract:

FRESH SEMEN CHARACTERISTICS OF LIMOUSIN AND SIMMENTAL BULLS AT THE ARTIFISIAL INSEMINATION CENTER, LEMBANG. This study was conducted to evaluate the characteristics of fresh semen in Limousin and Simmental bulls at the artificial insemination center in Lembang. Results of this study showed that ejaculation frequency of Simmental bull was significantly higher than that of Limousin with the average of 5.37 and 4.60, respectively. Variables of volume, pH and motility were not significantly different between both bulls with volume ranging of 7.17 – 7.20 ml, pH ranging of 6.65 – 6.66 and motility ranging of 58.08 – 59.29%, respectively. The fresh semen colour of Limousin and Simmental bulls were indicated by dominant color of milk white color. Semen consistency of fresh semen from both bulls was moderate. The ejaculation frequency and pH variables indicated the correlation of -0.32 in Limousine bulls, meaning that the higher the ejaculation frequency, the lower the pH (acid), but the ejaculation frequency and motility of semen had the correlation of 0,34, indicating the more the semen ejaculation frequency, the higher the motility of spermatozoa. The motility of semen had the negative correlation with pH (-0.49). The higher the pH (base), the motility of spermatozoa tended to decline. Simmental bull showed also that semen ejaculation frequency with volume had correlation of -0.40, indicating that the higher the semen ejaculation frequency yakni, the lower the semen volume. Semen ejaculation frequency had correlation of 0.5 with mortality, indicating that the higher the semen ejaculation frequency, the higher the motility of spermatozoa.Keywords: Semen, ejaculation, volume, color, consistency, pH, motility

Abstract:

ABSTRAKSemen adalah cairan yang dikeluarkan oleh organ kelamin ternak jantan yang secara normal diejakulasikan ke dalam saluran reproduksi ternak betina melalui kopulasi. Evaluasi semen merupakan alat utama untuk memprediksi kinerja reproduksi ternak ayam jantan. Evaluasi kualitas semen penting dilakukan untuk menyelesaikan salah satu masalah utama dalam peternakan pembibitan ayam, yaitu rendahnya fertilitas. Faktor terbesar dari sumber masalah tersebut terkait dengan rendahnya kualitas semen ayam. Kualitas semen ayam lebih banyak dipengaruhi oleh faktor non genetik, seperti faktor pakan dan nutrisi. Tujuan dari penulisan makalah ini adalah untuk mengkaji hasil-hasil studi terkait pengaruh pakan terhadap kualitas semen ayam. Hasil studi menunjukkan bahwa faktor pakan sangat mempengaruhi kualitas semen ayam, terutama imbangan energi metabolis-protein dalam pakan ayam jantan sangat penting diatur untuk menjaga berat badan ayam jantan agar tidak terjadi kelebihan atau kekurangan berat badan yang sangat mempengaruhi kualitas semen ayam. Suplementasi suplemen dan imbuhan pakan menjadi upaya yang dapat dilakukan untuk meningkatkan kualitas semen ayam. Jenis suplementasi yang dapat dilakukan dengan bahan sumber antioksidan, asam amino, mikromineral, bahan mengandung bioaktif tanaman, bahan sumber asam lemak dan probiotik. Disimpulkan bahwa faktor pakan sangat menentukan terhadap kualitas semen ayam.Kata kunci: ayam jantan, kualitas semen, pakanABSTRACTRooster semen is a liquid released by the genitals of the roosters which is normally ejaculated into the female reproductive tract during copulation. Semen evaluation is the main way to predict the reproductive performance of roosters. Semen quality evaluation is important to solve one of the main problems in poultry breeding farms, namely low fertility, whereas the biggest factor of this problem source is related to the poor of roosters’ semen quality. The quality of roosters semen is more influenced by non-genetic factors, such as feed and nutrition. The purpose of this paper was to examine the results of studies so far related to the effect of feed on the roosters’ semen quality. The results of the study indicated that the feed factor greatly influences the quality of roosters semen. The metabolic energy-protein balance in the rooster's feed was very important to regulate to maintain the weight of the rooster so as not to overweight and underweight because bodyweight greatly affects the quality of roosters semen. Supplementation of feed supplements and feed additives was an effort that can be done to improve the roosters semen quality. The kind of supplementation that could be done was supplementation of antioxidant sources, amino acids, microminerals, materials containing plant bioactive, fatty acid source ingredients, and probiotics. It was concluded that the feed factor was crucial to the quality of semen quality produced by the roosters.Keywords: feed, rooster, semen quality

Abstract:

This study evaluated the use of cooled semen in a fixed-time artificial insemination (FTAI) program compared with frozen–thawed semen to improve pregnancy rates in beef cattle. Ejaculates of three bulls were collected and divided into two treatments: (1) frozen–thawed semen and (2) cooled semen. Egg-yolk extender without glycerol was used for the cooled semen treatment. Straws (25 × 106 spermatozoa) were submitted to cooling for preservation at 5°C for 24 h, after which FTAI was performed. Nelore cows (n = 838) submitted to FTAI were randomly inseminated using frozen–thawed semen or cooled semen. There was a 20% increase in the pregnancy per AI (P AI–1) using cooled semen compared with frozen–thawed semen (59.9 ± 4.7 vs 49.4 ± 5.0%; P < 0.005). There was no difference in P AI–1 among the bulls (P = 0.40). The frozen–thawed semen had fewer functional spermatozoa than did the cooled semen when evaluated by sperm motility (61.7 vs 81.0%), slow thermoresistance test (41.7 vs 66.7%) and hypoosmotic swelling test (38.3 vs 53.7%; P < 0.05). The percentage of sperm abnormalities did not differ between the freeze–thawing and cooling processes (18.6 vs 22.1%; P > 0.05). Because there was less damage to spermatozoa and improvement in P AI–1, the use of cooled semen instead of frozen–thawed semen is an interesting approach to increase reproductive efficiency in cattle submitted to a FTAI protocol.
