Abstract
The objectives of the present research were to assess fresh and cryopreserved. seminal characteristics of breeding Beetal buck semen outside of its breeding tract. Semen was collected twice in a week from twelve Beetal bucks for 6 weeks. The mean value of ejaculate volume(ml), mass motility(o-5 scale), progressive motility(%), sperm viability (%), intact acrosome(%), sperm abnormality(%) and plasma membrane integrity(%) were ranged from 0.73 ± 0.08 ml to 1.17 ± 0.27 ml; 4.17+ to 4.67+, 80.83 ± 1.54 to 87.50 ± 2.14; 83.83 ± 0.95 to 90.33 ± 0.80; 87.00 ± 0.86 to 94.67 ± 0.33; 6.83 ± 0.31 to 10.33 ± 0.67 and 59.33 ± 1.52 to 66.67 ± 1.17, respectively. The mean value of post thaw sperm motility, post thaw sperm viability, post thaw acrosome integrity, post thaw sperm abnormalities and post thaw plasma membrane integrity were ranged from 52.50± 1.12 to 66.67 ± 1.67; 60.00 ± 1.24 to 69.67 ± 1.05; 66.00 ± 0.77 to 78.83 ± 2.15; 9.00 ± 0.45 to 12.83 ± 0.60 and 41.50 ± 1.18 to 53.50 ± 1.23, respectively. It was determined that, even outside of the breeding tract, the foundational characteristics of Beetal bucks are within the range defined for other Indian breeds of goat.
