Comparative appraisal of physicomorphological and enzymatic attributes of semen and their interrelationships in ox and buffalo bulls

Abstract

The seminal attributes, enzymatic profiles and their interrelationships were studied in 36 ejaculates each from 3 HF and 3 Murrah buffalo bulls during winter season. Ejaculate volume, abnormal sperm percent and G. O. T. values were higher in Friesian bulls semen, whereas, sperm concentration, live sperm percent, AKP, ACP and LDH activities were higher in Murrah bull semen. Sperm density, pH, mass activity, initial motility, GPT activity, freezability and fertility rates were of the same order in the two species. Most of the seminal attributes except ejaculate volume were interrelated in both the species. The semen enzymes were generally not correlated with seminal attributes in exotic bull semen, whereas, in Murrah, these with the exception of AKP were highly correlated with most of the seminal attributes. The semen quality in two species varied distinctly in respect of most traits. © Taylor & Francis Group, LLC.
