Semen was collected from four rams, using artificial vagina and viability%, motility% and plasma membrane integrity% were measured. Fresh ejaculates (n = 32) were separated by modified swim-up separation using modified human tubal fluid medium. Four fractions of supernatant were collected at 15-minute intervals. The mean volume, mass activity, concentration, motility%, viability%, normal morphology and membrane integrity% (HOST +ve) of fresh semen were 1.0 ± 0.14, 4.1 ± 0.1 × 109 spermatozoa/ml, 85.0 ± 1.3, 89.4 ± 1.0, 85.5 ± 0.7, 84.7 ± 0.5 respectively. There was no significant (P>0.05) difference in fresh semen quality parameters between rams. The motility%, viability% and HOST +ve % of first, second, third and fourth fractions were 53.4 ± 0.5, 68.2 ± 0.3, 74.8 ± 0.3 and 65.5 ± 0.4; 55.5 ± 0.4, 66.2 ± 0.4, 74.5 ± 0.3 and 73.6 ± 0.3 and 66.7 ± 0.5, 66.8 ± 0.5, 65.2 ± 0.4 and 74.7 ± 0.5 respectively. The motility%, viability% and membrane integrity% of separated semen samples differed significantly (P<0.05) between four fractions. The mean motility% and viability% were significantly higher (P<0.05) in third fraction (74.8 ± 0.3%), whereas the mean HOST +ve% was significantly higher (P<0.05) in fourth fraction (74.7 ± 0.5). All quality parameters of separated spermatozoa were significantly (P<0.05) lower than that of fresh semen. The pregnancy rates were higher with fresh semen (71%) in comparison to that of separated sample (57%).Bangl. vet. 2016. Vol. 33, No. 2, 62-70

First Time

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.

The experiment was conducted in a well-known private livestock research and development farm in Bangladesh to find out the variation of semen quality parameter among three generations (F1, F2 and F3) of Holstein Friesian upgraded breeding bulls. A total of 312 ejaculates were collected from 6 upgraded breeding bullsthrought the experimental year. The recorded data were summarized using Microsoft Excel 2010 and analyzed using GraphPad Prism 5 softwere. Out of the 312 ejaculates, 273 (87.50%) were found to be creamy in color followed by 26 (8.33%) and 13 (4.17%) as yellowish and watery, respectively. Generation had significant (P<0.05) effect on ejaculate volume, consistancy, mass activity, sperm concentration, initial and post freezing motility. The highest (7.389±0.19ml) and the lowest (5.156±0.13ml) volume of semen were found in third (F3) and first generation (F1), respectively. The mass activity ranges from 3.74±0.04 to 4.30±0.05. Sperm concentration and pH varied insignificantly (p>0.05) but initial motility and post freezing motility had the significant differences among the three generations. Initial motility ranges from 75.87±0.32 to 78.40±0.38 percent and the post freezing motility ranges from 50.38±0.41 to 52.16±0.43 percent. It could be concluded that most of the semen quality parameters were influenced by generation and freezing. Semen characteristics were better in F2 followed by F3 and F1 generation in upgraded Holstein Friesian bulls. Res. Agric., Livest. Fish.7(3): 457-463,  December 2020

Dietary Total Antioxidant Capacity

Abstract Study question Is there any association between dietary total antioxidant capacity (TAC) and semen quality parameters in male partners of couples attempting fertility? Summary answer Greater adherence to diets high in TAC was significantly associated with higher total sperm count, sperm concentration, and sperm motility. What is known already Among multiple factors that affect the etiology of poor semen quality and male infertility, dietary factors have an important contribution. Also, chronic oxidative stress negatively effects semen quality. Whether adherence to the diet rich in antioxidants is associated with better semen quality remains largely unexplored.The concentration of single antioxidant cannot show the total antioxidant power of the diet, therefore the concept of dietary total antioxidant capacity (TAC) was invented.Dietary scores are useful approach to evaluate the degree of adherence to specific dietary pattern and its benefits in regard to health Study design, size, duration This was a cross-sectional study of 350 men from couples attending a fertility center in Tehran, Iran, recruited between June 2015 and September 2019. Men aged 25–50 years with complete dietary data were analyzed. Participants/materials, setting, methods Diet was assessed via a reproducible and valid 168-item semi-quantitative food frequency questionnaire to determine the entire antioxidants of the usual diet in order to calculate dietary TAC. Semen quality was assessed according to World Health Organization 2010 guidelines. The association between dietary TAC and semen parameters were assessed adjusting for potential confounders through multiple logistic regression analysis. Main results and the role of chance The average age of study participants was 34.9 ± 7.6 years and their BMI was 28.5 ± 4.3 kg/m2. Participants in the lower tertile of the dietary TAC were lower educated (p &lt; 0.01), more physically active (p &lt; 0.05), and predominantly had abnormal sperm progressive motility (p &lt; 0.01). In the multivariable adjusted models, men in the lowest tertile of the dietary TAC Score had 2.9 times higher likelihood of having abnormal sperm motility, total sperm count and concentration, compared to men in the highest tertile of the TAC score (p &lt; 0.05). Limitations, reasons for caution The main limitation of our study was its cross-sectional design, limiting our ability to derive causal association. Wider implications of the findings: Our study suggests that dietary pattern comprising mainly of antioxidant nutrients may help improve semen quality. Our results are consistent with previous studies showing that plant-based diet contains higher levels of antioxidants are associated with better measures of semen quality.

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.
