Studies on Fresh and Cryopreserved Seminal Attributes in Beetal Bucks Outside their Breeding Tract

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.
