Abstract:

Two Boer crossbred bucks aged between 41/2 and 5 years which are maintained at Frozen Semen Bank, Department of Veterinary Gynaecology and Obstetrics, Veterinary College and Research Institute, Namakkal were utilized for this study. The semen was collected from two adult Boer crossbred bucks. The collected ejaculates were immediately transferred to semen processing laboratory and kept at 34°C water bath. The semen collected from the two bucks were pooled in to a sterile glass tubes and immediately subjected to further processing and cryopreservation and finally stored in liquid nitrogen container. These semen straws were subjected evaluation by CASA at various storage periods. The sperm motility parameters decreased slowly as the duration increases. A total of 10 Tellicherry does were selected and all the does were inseminated with frozen thawed buck semen prepared from TRIS universal diluent and the pregnancy was confirmed by ultrasonography at 45 days of gestation. The fertility rate was 70 per cent using semen diluted with TEYG universal diluent. The survival rate and fertility rate was higher in cryopreserved Boer crossbred buck semen diluted with TEYG extender.
