EFFECT OF SEMEN COLLECTION FLOOR ON SEXUAL BEHAVIOUR AND SEMEN QUALITY OF SAHIWAL BULLS

摘要

A study was conducted on Sahiwal cattle bulls maintained at the artificial breeding complex, NDRI, Karnal, Haryana, India, to evaluate the influence of type of semen collection floor on sexual behaviour and semen quality. Semen was collected from sixbulls once a week (2 ejaculates), on three types of collection floors viz, concrete, brick clay and rubber mattress for a total of two weeks for each type of collection floor. Sexual behaviour and semen quality traits considered were: Reaction time (RT),Dismounting time (DMT), Total time taken in mounts (TTTM), Fiehmen's response (FR), Erection Score (ES), Protrusion Score (PS), Intensity of thrust (ITS), Temperament Score (TS), Libido Score (LS), Semen volume, Physical appearance, Mass activity, Initial progressive motility, Non-eosiniphilic spermatozoa count (NESC) and post thaw motility percent. Data were analysed by least squares technique. Libido score, temperament score and semen volume (ml) were significantly (p<0.01) higher in rubber mattressgroup bulls than others, whereas concrete floor showed significantly (p<0.01) higher values of erection score, protrusion score, intensity of thrust than brick clay and rubber mattress floors. The results suggested that collection of semen on rubber mattress would result in better libido and higher ejaculate volume in Sahiwal bulls.
