Abstract:
An experiment was conducted to assess the hormonal profile in normal and repeat breeding buffaloes. Eight clinically healthy normal breeding and eight repeat breeding buffaloes presented to the Veterinary Dispensaries in and around Bidar were selected for the study. Hormonal parameters viz., estrogen, progesterone, tri-iodothyronine (T3), thyroxin (T4) were estimated during different phases viz. 0 day (day of oestrus), 11th day (mid luteal phase) and 16th day (early follicular phase) of the oestrus cycle. On the day of oestrus higher progesterone, in mid luteal phase higher estrogen and in early follicular phase lower progesterone was observed in repeat breeders. T3 and T4 levels were significantly lower on the day of oestrus in repeat breeders. It may be concluded that the altered hormonal profile may predispose the buffaloes to repeat breeding.
