Abstract

Forty-five crossbred bulls were categorized into good (n=20) and poor libido (n=25) on the basis of their reaction time (good <3 min, poor >3 min). Serum prolactin and thyroid hormone profile was similar (p>0.05) in both the categories, whereas, serum testosterone was high (p<0.05) and serum estradiol was low (p<0.05) in good libido bulls. In brief, testosterone to estradiol ratio is a differential feature between good and poor libido crossbred bulls.
