Seminal Attributes and their Correlations in Surti Bucks
Keywords:
Correlations, Seminal Attributes, Surti bucksAbstract
The present work was carried out to study seminal attributes of fresh ejaculates of Surti bucks and their correlations. Four healthy mature Surti bucks (aged >2 years) were selected. Fresh semen was collected twice a week for 8 weeks from each buck, i.e., 64 ejaculates (16 from each buck). Fresh semen was analyzed for color, pH, volume, density, mass activity/motility, sperm concentration/mL, and total sperm count/ejaculate. Fresh semen was pale yellow in color and its pH ranged from 6.7 to 6.9. The overall mean values of semen volume, density, mass activity/motility, sperm concentration, and total sperm count recorded were 0.47 ± 0.02 mL, 3.31 ± 0.08, 3.39 ± 0.08, 3932.81 ± 43.25 million/mL, and 1839.69±72.75 million, respectively. The ejaculate volume and sperm concentration/mL only varied significantly among bucks. Ejaculate volume was negatively correlated with sperm concentration/mL (r = -0.302), and positively with total sperm output/ejaculate (r = 0.961) and density score (r = 0.604), while the latter two were significantly interrelated (r = 0.605). The study established the normal values of fresh semen quality parameters of Surti bucks and their interrelations.
