Effect Of Age

Objective: To determine the effect of age and frequency of collection on quality parameters of Jersey bull semen at National Livestock Breeding Center (NLBC), Pokhara. Materials and Methodology: Nine Jersey bulls were selected randomly from NLBC. To obtain the effect of age, six bulls of three different age interval (3-4, 5-7 and 8-9 years) were selected randomly. Remaining three bulls were used to determine the effect of frequency of collection on semen quality. Studies were conducted for three months (Nov/Dec to Dec/Jan, 2016). Semen quality was analyzed using CASA system and SMILE software. ANOVA and paired t- tests were applied to find out level of significance. All the statistical analyses were done using SPSS 17.0 Results: Sperm concentration, post- thaw motility, live sperm, and abnormal sperm were significantly affected by the age of the bulls. Semen quality was found superior in the bulls belonging to 5-7 years of age intervals. Significantly higher value for semen volume, sperm concentration and post- thaw motility was obtained on second collection (P<0.05). However, volume initial motility, pre-filling motility, live sperm and abnormal sperm percentage did not differ significantly among different age intervals and between the frequencies of collection. Conclusion: Different quality parameters of semen like volume, concentration, initial motility, pre-filling motility, post thaw motility, live and normal spermatozoa percentages were higher in 5-7 years old bulls and in second collection of semen.

Effect Of Age

The present study was undertaken to determine the effect of age and frequency of collection on quality parameters of Jersey bull semen at National Livestock Breeding Center (NLBC), Pokhara, Kaski district. Nine Jersey bulls were selected randomly from NLBC. To obtain the effect of age, six bulls of three different age interval (3- 4, 5-7 and 8-9 years) were selected randomly. Remaining three bulls were used to determine the effect of frequency of collection on semen quality. Studies were conducted for three months (Nov/Dec to Dec/Jan 2017). Semen quality was analyzed using CASA system and SMILE software. ANOVA and paired t- tests were applied to find out level of significance. All the statistical analyses were done using SPSS 17.0. Sperm concentration (0.551 ±0.004 to 1.084 ± 0.014x109), post- thaw motility (42.44±0.11 to 51.72±0.03 %), live sperm (45.62 ± 0.13 to 51.23±0.15 %), and abnormal sperm (11.57±0.12 to 19.59±0.24%) were significantly affected by the age of the bulls. Semen quality was found superior in the bulls belonging to 5-7 years of age intervals. On the other hand, volume (3.98±0.09 to 6.72±0.06 ml), initial motility (72.68±0.02 to 78.64±0.15 %) and pre-filling motility (71.34±0.17 to 77.62±0.02 %) did not differ significantly among different age intervals. Significantly, higher value for semen volume (3.98±0.12 to 6.02±0.14 ml), sperm concentration (0.572±0.119 to 1.095±0.015) and post- thaw motility (40.34±0.21 to 48.54±0.06% was obtained on second collection. However, initial motility (70.58±0.06 to 75.64±0.13 %), prefilling motility (68.11±0.12 to 71.62±0.02 %), live sperm (53.27±0.54 to 56.17±0.02 %) and abnormal sperm (12.31±0.12 to 14.3±0.47 %) did not differ significantly between the frequencies of collection. Different quality parameters of semen like volume, concentration, initial motility, pre-filling motility, post thaw motility, live and normal spermatozoa percentage were higher in 5-7 years old bulls and in second collection of semen.

A study was carried out on semen ejaculates (40) of five healthy Surti buffalo bulls during favourable breeding season. The ejaculates with >70% IM were diluted @ 100 million sperms/ml in Tris-fructoseegg yolk-glycerol (TFYG) diluent supplemented with L-cysteine @ 1 mg/ml, and examined for quality parameters such as sperm progressive motility, viability, morphology, acrosomal and plasma membrane integrity. A part of the extended semen was preserved at 5°C and another was processed for ultra-low temperature (-196°C) preservation in LN2 using biofreezer after filled in French mini straws. The mean values of ejaculate volume, sperm concentration, mass activity (0-5 score), individual sperm motility, live sperm, abnormal sperm, intact acrosome and HOS reactive sperms observed in fresh semen were 3.04±0.11 ml, 963.05±50.97 million/ml, 2.97±0.06, 75.00±0.69 %, 88.22 ±0.48 %, 4.40±0.26 %, 93.67±0.31 % and 89.17±0.57 %, respectively. Just after dilution the percentages of progressively motile, live & abnormal sperms, intact acrosomes and HOS reactive sperms were 80.51±0.65, 85.95±0.65, 4.92±2.20, 91.00±2.30, 85.72±0.67, respectively. The corresponding values after 48 hrs of refrigeration (5°C) were 61.75±0.85, 67.85±0.85, 6.45±0.27, 89.05±0.32, 67.30±0.96%, the values at pre-freeze stage (after equilibration) were 72.62±0.69, 78.97±0.93, 5.45±0.25, 90.90±0.35, 78.12±0.79% and at post-thaw stage (37°C/30 sec) 46.50±0.72, 52.97±0.79, 7.10±0.26, 85.73±0.18, 51.62 ±0.82%, respectively. The mean motile spermatozoa observed after 1, 2 and 3 h of post-thaw incubation at 37°C in water bath were 32.75±0.82, 18.88 ±0.70 and 8.88±0.66% (P<0.01), respectively. The semen quality parameters, fresh and cryopreserved were acceptable for artificial breeding use. The seminal traits in initial, 48 hrs refrigerated, pre-freeze and post-thawed samples revealed significant (p<0.01) interrelationships (r = 0.44 to 0.84) between progressive motile sperm, live sperm and HOST reactive sperm directing more emphasis on these quality parameters for better semen evaluation.

A total of sixteen rabbits sourced from two locations in Southeastern Nigeria were used for this study. Semen was collected from all the rabbits twice weekly for eight weeks using an artificial vagina while observation on the effect of time of collection on semen quality were also made. The results obtained indicated that time of collection had no significant effect (P > 0.05) on all the seminal characteristics measured. However, source of the animals showed significant effect (P < 0.05) on semen volume, sperm concentration, total sperm per ejaculate and proportion of abnormal sperm. Average semen volume, sperm concentration and total sperm per ejaculate were: 0.69±0.007 ml, 104.0±1.44 x 106/m1 and 71.40±0.90x106 respectively for the rabbits sourced from Port Harcourt. The corresponding values for rabbits sourced from Owerri were: 0.66±0.008m1, 96.02 ±1.63x106iml and 63.49±1.50 x 106 respectively. Abnormal sperm proportions were 11.05±0.22% and 1216 ± 032% for the rabbits sourced from Port Harcourt and Owerri respectively. There were no significant (P> 0.05) differences observed between locations in live sperm concentration and sperm motility. Live sperm concentration and sperm motility were 87.75±1.09% and 71.62±0.74% for the Port Harcourt group, while the values obtained for the Owerri group were 88.06±034% and 71.19±0.89% respectively.

Selection of high fertile bulls with the help of marker assisted selection has gained importance in recent years. The low heritability of fertility traits hampers improvement of these traits by conventional selection based on phenotypic records. No information is available on the role of SNPs in KiSS1 gene in cattle on semen quality parameters in bovines. KiSS1 genes code for Kisspeptin, which are essential upstream regulators of neurons secreting gonadotropin-releasing hormone and play crucial role in reproduction.The coding regions along with exon-intron boundaries of KiSS1 gene, was characterized using PCR-SSCP method and direct sequencing. Two genotypes were observed which were represented as SSCP pattern 1 and pattern 2 and found to carry one SNPs (T153C) and one insertion of G at 291_292bp. The bulls with pattern 2 were heterozygous with respect to the transition T153C and pattern1 bulls were homozygous with TT genotype. The transition was predicted to cause amino acid change from Valine to Alanine. The frequency of bulls with pattern1 and pattern 2 were 0.67 and 0.33 in 67 Holstein Friesian bulls and 0.73 and 0.27 in 13 Khillari bulls. The association study of genotypes with semen quality parameters revealed significant association of genotypes with acrosome integrity in fresh semen (P less than 0.05) and no association with sperm concentration, volume per ejaculate, percent live sperm and Hypo Osmotic Swelling Test (HOST) with higher acrosome integrity in bulls with pattern2. Upon validation of the results in larger population and identifying the exact role of the novel SNP T153C and insertion of G at 291_292bp, they could be incorporated in selection programme for improving fertility in bulls.as markers for acrosome integrity in cattle.

The present study was carried out on 80 ejaculates, 20 each from four healthy Jaffrabadi breeding bulls to see the relationship betweensexual behavior and semen quality parameters. The results depicted that the overall mean values of libido score, mating ability score andsexual libido score between bulls. The overall color of semen ranged from thin white to very thick creamy. The overall values for semen volume(ml), pH, sperm concentration (million/mL), mass activity, individual sperm motility (%) and live spermatozoa (%) were 2.99 ± 0.12, 6.80 ± 0.01, 1439.68 ± 48.46, 3.94 ± 0.03, 89.51 ± 0.21 and 95.00 ± 0.19, respectively. The values for semen volume, sperm concentration,mass activity (%) and live sperm (%) differed significantly (p less than 0.05) between bulls. There were significant positive correlations (p LESS THAN 0.01)of libido with mating ability, sexual behavior score and ejaculate volume of semen (r = 0.37 to 0.87), while a negative correlation wasfound with sperm concentration (-0.30). Mating ability was significantly (p less than 0.01) correlated with sexual behavior score and ejaculatevolume (0.78, 0.67), and sexual behavior was correlated with semen volume (0.84). Sperm concentration was significantly (p less than 0.05 correlated with mass activity (0.29), while individual sperm motility was positively (p less than 0.05) correlated with live sperm percentage (0.25).Correlations of libido, reflected the importance of sexual behavior of Jaffrabadi bulls in predicting their future utility as a proficient breeder under AI program.

The aim of study was to examine the effect of the boar ejaculate collection frequency on the parameters of its quality. The research covered a three-year period, and four most common boar breeds in our area. A total of 1705 ejaculates were taken from Yorkshire boars, 1693 ejaculates from Landrace boars, 1106 ejaculates from Pietrain boars and 669 ejaculates from Duroc boars. Within each breed, groups were formed according to the frequency of ejaculate taking (once, twice, three, four, five, or six times a month). Evaluation of ejaculate quality was performed in a reprocentre laboratory, according to their quality standards. Quality parameters that have been determined were the volume of ejaculate, sperm concentration, progressive sperm motility, live sperm count, the number of doses per ejaculate and the overall assessment of ejaculate. Results of this study show that the volume and progressive motility increase with the increase of frequency in ejaculate taking, while the sperm concentration drops, except for the Pietrain boars. The best results were observed in ejaculates collected 5-6 times during the month. The highest mean volume of ejaculate was found in the Landrace boars (292.22 ml), in ejaculate taking frequency of five times per month. The highest average progressive sperm motility was 92% in the Yorkshire boars, on collection frequency of six times a month, while the highest concentration of spermatozoa was found in the Duroc boars in collection frequency of one taking per month (447.32 mil/ml). The results of this study indicate that the frequency of ejaculate taking affects the boar semen quality parameters.

The present study was undertaken to elucidate the effect of age on semen quality of naked neck and dwarf chicken lines under tropical climatic conditions. Semen collected by abdominal massage at 4-week intervals from 24 to 48 weeks of age was evaluated for different semen quality parameters. Except sperm concentration and appearance, all other parameters were significantly (P < 0.05) affected by the age of the birds. The semen volume, motility, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide dye reduction test and percentage of live sperm were significantly (P < 0.05) lower at 24 weeks of age compared with 40 weeks of age. At 24 weeks of age the dead sperm percentage was significantly (P < 0.05) high and with advancing age it decreased. There was a significant difference (P < 0.05) between the gene lines for volume, appearance, motility, sperm concentration, and percentage of live and dead sperm. Except for sperm concentration, significant (P < 0.05) interaction between gene lines and age was observed in other parameters. In conclusion, semen quality was different between naked neck and dwarf line males and age affected semen quality of the gene lines studied in different manners.

The current study was planned to evaluate the supplementation of Polyvinylpyrrolidone in extender on cryopreservation of Nili-Ravi buffalo bull semen. The semen samples were collected from Nili-Ravi buffalo (Bubalus bubalis) bull kept at SPU Qadirabad, District Sahiwal, Pakistan. Qualifying semen ejaculates having motility >60%, volume >5-6ml and concentration >0.5 billion/ ml were diluted 50 × 106 motile sperm ml approximately at 37°C in Tris-citric acid extender supplemented with different concentrations of PVP (0.01, 0.05, 0.1mM). The extender without PVP was kept as control. Semen was stored at 4°C for a period of 2 h and kept at 4°C for 4h. Semen was filled in 0.5 ml French straws using suction pump at 4°C, plunged and stored in liquid nitrogen (-196°C). Semen straws were rewarmed at 37°C for 30 seconds and assessed for sperm motility, plasma membrane integrity (PMI), dead sperm percentage and the live sperm percentage. The data on the role of PVP on different parameters of semen quality were analyzed by using ANOVA and RCBD. Higher percentage (P< 0.05) of sperm motility (66.1±7.51 and 59.4±10.72) and PMI (72.9±5.39 and 75.7±6.5) was observed in extenders having 0.05 mM and 0.1mM PVP compared to extenders having 1.5mM PVP and control. The percentage acrosomal integrity was observed greater (P< 0.05) in extended semen containing 0.1mM (68.2±0.50) PVP compared to extenders having 0.01 and control.

In order to evaluate the results of reproductive cows and heifers, different parameters of fertility are used, such as the service period, insemination index, intercalving time and others, and of the breeding bulls the values obtained through non-return. An ejaculate is taken up for further processing by veterinary centres only provided it meets the prescribed quality parameters. Rating semen parameters includes a macroscopic (volume, colour, consistency, smell and pH) and a microscopic evaluation (mobility, density, percentage of live sperm and abnormal and damaged sperm). In addition to sperm quality and the fertility of the female animal, the results of the non-return method are also influenced by a number of exogenous causes (season, age, race, insemination techniques) that have no small impact on the end result of insemination - pregnancy. In order to obtain more objective results of the fertility of bulls the following tasks were undertaken, namely: 1. to calculate with the non-return method the fertility of bulls in over 10,000 cows inseminated for the first time during a period of 6 years; and 2. to analyze the impact of semen quality, season, age of cow and bull, and the bull breed on the results of fertility.
