Impact of Housing Management Systems on Seminal Characteristics and Semen Freezability in Sirohi Bucks

Abstract

This study was conducted to determine the effect of the management system (semi- intensive and intensive) on Seminal Characteristics and semen freezability in Sirohi bucks. A total of 6 Sirohi bucks were randomly allotted into two groups, viz., Group 1 (semi-intensive system, 3 bucks) and Group 2 (intensive system, 3 bucks). The results showed that in the fresh semen the ejaculate volume and mass motility were significantly (p<0.05) higher in Group I (0.88±0.03 ml, 4.69±0.08) compared to Group II (0.73±0.04 ml, 4.39±0.11) respectively. The sperm concentration, total sperm output per ejaculate, initial progressive motility, sperm livability, acrosomal integrity and plasma membrane integrity were found to be significantly higher (p<0.05) in Group 1 compared to Group 2. The enzyme leakage (AST and ALT) level were found to be significantly higher (p<0.05) in Group 2 compare to Group 1. Similar patterns were also seen in post-thaw seminal parameters too. Based on the findings of the study, it was concluded that the housing plays a crucial role in determining the seminal parameters. The value for different parameters of superior semen was recorded to be highest during semi-intensive system as compare to intensive system.
