The aim of the study was to investigate the effect of dietary supplementation of vitamin E on the semen characteristics of the Markhoz goats. Eighth bucks were randomly allocated into two groups, and received two different diets: unsupplemented diet (control) and supplemented diet with vitamin E (0.30 g/Kg DM). All experimental diets were formulated according to AFRC 1998. Semen was collected at 14-days intervals from June 17, 2006 to September 2, 2006 (non-breeding season) using artificial vagina. Semen characteristics were evaluated including semen volume, sperm concentration, live sperm percentage, percentage of motility and progressive motility. This characteristics were evaluated at two weeks intervals the trial. The total number of spermatozoa per ejaculation was calculated by multiplication of the semen volume with sperm concentration. Sperm motility was also analyzed by placing a sample on pre-warmed (37 º C) microscope slide covered with a cover slip, and examined under a high power microscope at a magnification × 200. Data was analyzed using proc MIXED in SAS program. Significant effect (P≤0.05) of the week (sampling time) was observed for all the parameters except for semen volume. Vitamin E supplementation significantly improved (P≤0.05) total number (Control: 263.7 ×107±17.506 vs. Vit E: 320.95 ×107±17.506) and sperm concentration (Control: 301.79 ×107±13.657 vs. Vit E: 386.57 ×107± 13.657), motility (Control: 77.27% ±0.89 vs. Vit E: 82.6% ±0.89) and progressive motility (Control: 4.208 ±0.138 vs. Vit E: 4.229 ±0.138), percentage of viability (Control: 80.57% ±0.89 vs. Vit E: 85.9% ±0.89). The results suggested that the supplemental Vitamin E may improve the semen quality and fertility in the Markhoz goats.

The experiment was carried out to compare the semen characteristics of indigenous and Amo strains of cockerel at poultry unit of teaching and research farm of Federal University of Kashere, Gombe State, Nigeria. Semen samples were collected from nine indigenous and nine Amo breeds of cockerel at three days interval for two weeks using abdominal massage technique. Semen samples were examined macroscopically for semen colour, pH and ejaculation volume. Then, microscopic observation was carried for sperm concentration, mass motility, progressive motility, live and dead sperms percentage, normal and abnormal sperm, all for semen characteristics. The results showed a significant difference (P ≤ 0.05) between mass motility, progressive motility, sperm concentration and head defects of 4.85 ± 0.27 to 4.37 ± 0.19, 95.13 ± 0.43 to 81.63 ± 1.15%, 4.93 ± 1.84 to 3.40 ± 1.07×109/ml and 2.96 ± 0.17 to 3.44 ± 0.12% for indigenous and Amo breeds of cockerel, respectively. There were no significant differences observed as semen colour, ejaculate volume, semen pH, live / dead normal sperm neck (mid-piece), tail defects and sperm total abnormalities were found to be 2.85 ± 0.07 to 2.00 ± 0.090.21 ± 0.17 to 0.20 ± 0.02 /ml, 88.85 ± 0.58 to 72.70 ± 0.54% /ml, 11.14 ± 0.58 to 27.29 ± 0.54%, 81.00 ± 0.78 to 66.22 ± 0.61%,9.03 ± 0.42 to 13.96 ± 0.47%, 9.70 ±  to 13.00 ± 0.30 and 21.70 ± 0.59 to 30.40 ± 0.53% for the indigenous and Amo breed groups of cockerel, respectively. It was concluded that semen quality characteristics could be differed between genetically improved (Amo strain) and indigenous breed of cockerels.

Abstract STUDY QUESTION How does age affect various semen parameters? SUMMARY ANSWER For most semen parameters, the nomogram of the entire population was biphasic, peaking around the fourth decade of life. WHAT IS KNOWN ALREADY In clinical practice, semen quality is examined by using the WHO 2010 reference limits but these limits do not account for male age. A percentile-based, large-scale nomogram describing how different semen parameters change throughout reproductive life has been lacking. STUDY DESIGN, SIZE, DURATION A retrospective study was conducted with 12 188 sperm samples, obtained from individuals who attended the McGill University Health Centre reproductive clinic between 2009 and 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS One sample from each individual who attended the clinic during the study period was analysed by using computer-assisted sperm analysis (CASA). The analysed parameters were human-verified and included sperm concentration, motility, progressive motility, total count, morphology and semen volume. Based on this analysis, the entire dataset (n = 12 188) was further divided into two groups of samples: samples that surpassed the WHO 2010 lower reference limits (‘above reference limits’ group, ARL; n = 6305), and samples that did not (‘below reference limit’ group, BRL; n = 5883). Regression quantiles were fitted as a function of age to generate age-dependent nomograms, and these quantiles were divided into 5th, 25th, 50th, 75th and 95th percentiles. MAIN RESULTS AND THE ROLE OF CHANCE In the entire dataset, age had a significant influence (P &lt; 0.001) on all parameters (except morphology) which demonstrated a biphasic trend peaking in the fourth decade of life. In the ARL group, age had a significant influence (P &lt; 0.01) on all semen parameters except sperm concentration and morphology. However, unlike in the entire dataset, only semen volume demonstrated a biphasic trend in the ARL group (peaking in the fourth decade of life), whereas other parameters either remained unchanged (concentration and morphology) or consistently declined with age (sperm motility, progressive motility and total sperm count). Percentile-based nomograms were generated for individuals between the ages of 20 and 60 years in the entire dataset and in the ARL group. LIMITATIONS, REASONS FOR CAUTION First, the semen samples were obtained from individuals who were referred to a fertility clinic, such that the entire dataset does not necessarily represent the general population. Second, the cross-sectional sampling design increases variance, and the nomograms are less accurate in the 5th and 95th percentiles and at the extremes of the age distributions. Third, the observed age-dependent changes in semen parameters do not necessarily indicate changes in fertility, as not all factors that affect male fertility were analysed. Fourth, some of our semen analyses employed CASA, which can have variability issues. Finally, our models did not incorporate possible secular trends. WIDER IMPLICATIONS OF THE FINDINGS We provide the first nomogram that correlates age with semen quality parameters in different population percentiles, thus complementing the current reference limits set by the WHO in 2010. Most examined semen parameters in our study changed non-linearly with age; therefore, age should be regularly employed as a factor in the clinical analysis of semen samples.

Time Of Collection

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.

(Effect of supplementation of vitamin E, Selenium and Zinc mineral against to nutrient consumption, production and quality cement simental cow)ABSTRACT. Simental bulls often experience a decline in production and semen quality in the rainy season, which have a higher humidity and high rainfall. This study aims to maintain nutrient consumption, production and semen quality Simental bulls during the rainy season through the supplementation of Vitamin E, Selenium and Zinc Minerals. The study was conducted in July-December 2012 at the Artificial Insemination Center (BIB) Unggaran. The research material used in this study were 12 males Simental cows BIB Unggaran grouped by age. The experimental design used in this study is a randomized block design (RBD) with 3 treatments T1 (ration + Vit. E), T2 (ration + Vit. E + Se), T3 (ration + Vit. E + Se + Zn) and 4 groups as replicates. Parameters measured were dry matter intake and nutrient consumption, production and semen quality. Cement production was measured from fresh semen volume during the study, whereas semen quality measured motility and concentration of spermatozoa from fresh semen. Data consumption of dry matter and nutrient intake obtained were processed using analysis of variance, followed by Duncan test. While data on production and semen quality were analyzed descriptively. The results showed that the combination of vitamin E supplementation, minerals Selenium and Zinc did not affect dry matter intake, total digestible nutriens and crude protein, but resulted in a decrease in the percentage of shelter, semen volume, sperm motility and concentration smaller than before treatment. Treatment T1, T2 and T3 resulted in a decrease in the number of shelter respectively 41,55%, 19,56% and 13,63% compared to before treatment, whereas a decrease in semen volume unchanged at 44,9 %, 43,7% and 40,99%. Sperm motility due to treatment T1, T2 and T3 respectively decreased by 55,87%, 22,10% and 13,63% compared to before treatment. In line with sperm motility, sperm concentration in treatment T , T2 and T3, respectively decreased by 49,16%, 22,85% and 14,88%. The conclusion is a combination of vitamin E supplementation, minerals Selenium and Zinc can prevent the decline in cement production, sperm motility and sperm concentration Simental bulls during the rainy season.

The purpose of this study was to examine sperm quality after cryopreservation of ejaculates collected as a bulk sample, which is routinely part of semen collection, and to compare this quality with the sperm-rich fraction in boars. Ejaculates were collected as sperm-rich fractions (SRF) and bulk samples (BE) using a gloved-hand technique. Fresh semen quality in terms of semen volume, sperm concentration, total sperm motility and pH were conventionally evaluated. Then, semen was cryopreserved using the liquid nitrogen vapour method. The post-thaw sperm quality was evaluated by assessing sperm motility, live sperm with normal apical ridge and high mitochondrial energy status, lipid peroxidation was evaluated using CASA and fluorescent multiple staining and MDA levels were determined using a spectrophotometer, respectively. In terms of fresh semen quality, sperm motility in fresh semen did not differ significantly between the two groups. The treatment with the greater mean volume (BE; P &lt; 0.05) had a lower mean sperm concentration (P &lt; 0.05); meanwhile, the mean ejaculate pH collected as BE was more basic compared with SRF (P &lt; 0.05). However, there were no significant post-thaw quality changes between sperm-rich fractions and bulk samples of semen. In conclusion, ejaculates can be collected as bulk samples without the need to classify fractions for boar semen cryopreservation.

Abstract This study was designed to evaluate the effects of electronically-controlled floor cooling pads on thermoregulatory and reproductive parameters in boars during heat stress (HS). Boars (n = 24) were randomly assigned to crates with non-functional pads (CON) or pads that were flushed in either 8-min intervals or when the pad reached 28.5°C (FLUSH). For 3 d, boars were subjected to cyclical HS (28 to 35°C; &gt;65% relative humidity). Boars were fed 2.4 kg/d and daily feed intake was recorded. Respiration rate (RR), rectal temperature (Rtemp) and skin temperature were recorded every 2 h during HS (via IR camera), testicular temperature was recorded twice daily. Semen was collected d7 and d14 before HS, the day following HS and weekly for 6 weeks and evaluated for volume, sperm concentration, motility, progressive motility, morphological abnormalities, and viability. After 2 h of HS, FLUSH boars had reduced RR (P &lt; 0.001) and RTemp (P &lt; 0.001) when compared to control boars, and this difference was maintained throughout HS. Skin and testicular temperature were reduced in FLUSH vs. CON boars after 6 h of HS (P &lt; 0.05). Semen volume was greater in FLUSH vs CON boars (P = 0.01) resulting in a tendency for an increase in total sperm per ejaculate (P = 0.075). From weeks 2 to 5 post-HS, FLUSH boars had increased motility (P = 0.006) and progressive motility (P = 0.001), with corresponding increases in sperm kinematic motion parameters when compared to CON boars. The number of morphologically normal sperm cells were increased (P = 0.006) in FLUSH vs CON boars due to reduced distal droplets (P = 0.033) and proximal droplets (P &lt; 0.001). Abnormal acrosomes were reduced (P &lt; 0.001) in FLUSH vs CON boars at week 3 post-HS. In summary, electronically controlled cooling pads effectively reduced negative thermoregulatory indicators of HS and minimized or removed the negative impacts of HS on semen quality in boars.

In poultry breeding program the success of artificial insemination (AI) is highly influenced by  the quality of semen. The aim of the present research was to evaluate the variations in semen characteristics of three phenotypes of chicken of the same specie raised in Akko, Nigeria. A total of 9 cocks from threedifferent phenotypes; Red feathered (n = 3), White feathered (n = 3) and Black feathered (n =3). The semen was evaluated for macroscopic (i.e. semen volume and colour) and microscopic (i.e. sperm concentration, motility and morphology) criteria after being collected by abdominal massage method. There were phenotypes variation (P > 0.05)effects on semen motility, number of live/dead sperm and sperm abnormalities. No differences(P>0.05) were observed on volume, colour, concentration, mass motility and pH of semen. The observed sperm progressive motility was ranged from 90.5 ±1.21% to 95.09±0.82%. The White feathered strain had the highest sperm progressive motility (P<0.05)and highest value for live and normal sperm (93.5±0.63% and 87.90±0.25%), while the black feathered had the least and (92.4±0.73% and 85.5±0.50%) respectively. The Red feathered strain had the highest value for both dead and sperm head defect (9.2±0.33%and 7.0±0.52%). Whilst, the Black feathered strain scored the highest percentage of both sperm tail and neck defects with values ranged from 11.4±0.43%to 14.2±1.08% and 19.4±0.53% to 23.6±0.69%, respectively. This study suggests that there are large variations present in semen characteristics of different phenotypes of cocks; White feathered strain is likely have better semen characteristics compared to Red and Black feathered strains. Therefore, White feathered strain can potentially be used in artificial insemination (AI) for chicken production and improvement.

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.
