Correlation Coefficient Matrix of Surti Buck Semen Parameters

Abstract

The present work was carried out to study seminal parameters of fresh ejaculates of Surti bucks and their correlations. Four healthy mature Surti bucks above one years of age 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, volume, density, mass activity, sperm concentration/mL, and total sperm count/ejaculate. In the present study, the fresh semen colour was pale yellow in all ejaculates of Surti buck. The overall mean values of semen volume, density, mass activity/motility, sperm concentration, and total sperm count recorded were 0.53±0.02 mL, 3.23±0.08, 3.34±0.09, 3683.36±60.17 million/mL, and 1880.8±29.51 million, respectively. All the parameters of ejaculate semen were non-significantly differed among bucks. Correlation coefficients (r) between various parameters of Surti buck fresh semen revealed that the semen volume showed significant (p<0.01) positive correlation with total sperm count (r=0.851) and significant (p<0.01) negative correlation with sperm concentration (r=-0.896) whereas, non-significant negative correlation with semen density (r=-0.092) and mass activity (r=-0.064). The study established the normal values of fresh semen quality parameters of Surti bucks and their interrelations. By understanding the interrelations between these parameters, breeders can now make informed decisions and achieve better breeding outcomes.
