Abstract

A study was conducted to assess the hormonal status in 70 repeat breeder and 14 regular breeder cows and buffaloes in
Chennai, Tamilnadu. Circulating progesterone level was higher on day 0 and lower on day 7 in repeat breeder than in regular breeder.
Estrogen level was lower on day 0 and day 7 in repeat breeder than regular breeder cows and buffaloes. Regular breeder cows had a
significant higher level of T3 and T4 on day 0 than the repeat breeder cows and buffaloes. It is concluded from the study that this
difference in hormonal concentration of repeat breeders from regular breeders might be resJf<>nsible for the reproductive disorders in
cows and buffaloes.
