COMPARATIVE APPRAISAL OF PHYSICOMORPHOLOGICAL AND ENZYMATIC ATTRIBUTES OF SEMEN AND THEIR INTERRELATIONSHIPS IN OX AND BUFFALO BULLS

The seminal attributes, enzymatic profiles and their interrelationship s were studied in 36 ejaculates each from 3 HF and 3 Murrah buffalo bu lls during winter season. Ejaculate volume, abnormal sperm percent and G.O.T. values were higher in Friesian bulls semen, whereas, sperm con centration, live sperm percent, AKP, ACP and LDH activities were highe r in Murrah bull semen. Sperm density, pH, mass activity, initial moti lity, GPT activity, freezability and fertility rates were of the same order in the two species. Most of the seminal attributes except ejacul ate volume were interrelated in both the species. The semen enzymes we re generally not correlated with seminal attributes in exotic bull sem en, whereas, in Murrah, these with the exception of AKP were highly co rrelated with most of the seminal attributes. The semen quality in two species varied distinctly in respect of most traits.
