Evaluation of seminal parameters associated with subfertility in sahiwal bulls

Abstract

The present study was conducted on Sahiwal bulls maintained at Artificial Breeding Research Centre (ABRC), National Dairy research Institute (NDRI), Karnal, with an objective to evaluate seminal parameters associated with sub-fertility. Based on the available record at ABRC, 9 sahiwal bulls were selected and classified into three categories, viz, 3 bulls in poor semen freezability, 3 bulls in poor semen quality and 3 bulls in normal. All the seminal parameter evaluated under study i.e., mass motility, individual motility, live percent (non-eosinophilic) count, sperm concentration, hypo-osmotic swelling test, and post-thaw motility showed significant association between different categories of bull (P
