...Friesian) to compare the semen quality. Semen samples were individually diluted with egg yolk extender and tested for individual motility, progressive motility, plasma membrane integrity, acrosomal and DNA integrity, seminal pH and dead sperm percentage in fresh and thawed semen. Data were subjected to one way analysis of variance. High sperm individual motility (85.12 ± 0.51%), progressive motility (20.25 ± 0.47%), plasma membrane integrity (82....

...measured weekly, whereas semen quality, and histopathological profile were investigated at week 10.The obtained results reveal that under a long photoperiodthe sexual activity of the control lasted only 04 weeks, characterized by significant increase in the testicular volume, followed by spontaneous gonadal regressionup to week 10. Consequently, an azospermia and lack of germ cells in control birds was noticed,which confirm the testicular regression.In the tre...

...xamined for post chilled semen quality, motility% (74.75±1.9), morphology% (86.62±1.2), membrane integrity% (87.87±0.6), live dead ratio% (87.62±0.7). After that samples were frozen for 24 hours, frozen thawed results showed motility (57.00±0.5), morphology (73.50±1.5), membrane integrity (70.00±0.01), live dead ratio (72.00±0.8 were high in 2mM/ml concentration of selenium. Overall results showed that 2m...

...s does in the breed. The semen quality was high in different seasons. Dazu black goats might have shorter gestation period (147.9±1.7 days) and have longer kidding interval (237.8±4.6 days). The percentages of singletons, twins, triplets and quadruplets born were 1.98, 47.27, 40.02 and 10.29 %, respectively. The mean litter sizes (2.60±0.72) were the highest among the reported meat goat breeds in China. Dazu black goat reached the highest ...

A total of 8 adult (≥2 year) bulls (2 each from Jersey, Friesian, Sahiwal and cross bred) were selected with body condition score (BSC) at a scale of (0-5). The results showed that mean semen volume was significantly (P<0.05) high in Friesian bull. Sperm concentration and motility were significantly (P<0.05) high in Jersey bull while live sperm percentage was significantly (P<0.05) high in J...
