Preservation of Konkan Kanyal buck semen at refrigeration temperature

Abstract

Semen evaluation is essential to evaluate the buck potential of fertility before it is used to produce semen and perform artificial insemination. Therefore present study was carried out to investigate the preservation of the Konkan Kanyal buck semen at refrigeration temperature in egg yolk extender. Total seven semen samples, were collected from Konkan Kanyal bucks using an artificial vagina method. The collected semen sample was evaluated for macroscopic, microscopic and sperm function tests. For dilution 20% egg yolk extenders were used and the diluted semen samples were stored at 4°C, for 4, 12, 24, 48, and 72 hours. The post-preservation evaluation semen and CASA parameters revealed a decline in semen parameters with longer storage times. From the present study, it was concluded that, Tris egg yolk extender is a suitable dilutor to preserved Konkan Kanyal buck semen at acceptable range for Artificial Insemination (AI) upto 72 hours of refrigeration temperature.
