Influence of excercise and by-pass protein feeding on seminal attributes of Mehsana buffalo bulls.

摘要

Twenty-four adult Mehsana buffalo bulls (2.5-5.0 years old) were subjected to 4 treatments: control (T1), exercise (T2), bypass protein feed (T3) and exercise with bypass protein feed (T4). Initial seminal attributes such as ejaculate volume, mass activity, initial motility, sperm concentration and total sperm output per ejaculate showed improvements (5.5 to 33.5%) in T4 compared with the control. Sperm concentration significantly improved in T2 and T3 bulls compared with the control. Semen qualityparameters (sperm abnormality, live/dead sperm and acrosomal integrity) showed maximum improvement (3.6 to 43.2%) in T4 followed by T2 (1.5 to 31.5%) and T3 (2.5 to 29.6%) over the control. Semen volume, and sperm quantity and quality were better duringwinter, initial motility was better during summer and acrosomal integrity was maximum during the monsoon. A combination of exercise and bypass protein feeding had a beneficial effect on semen quality and quantity in Mehsana bulls.
