Abstract: Age at puberty has an influence on the lifetime productivity of the animal. The heifer which has attained puberty earlier will also have its first conception earlier and a greater number of calving can be obtained during the lifetime of the animal. The incidence of delayed puberty was studied in 117 buffalo heifers in and around Jabalpur. The age, approximate body weight, the first sign of oestrus and body condition score was recorded during the study. The suspected delayed pubertal heifers were examined per rectally to ascertain the ovarian function i.e. the presence of follicles or corpus luteum. The buffalo heifers with smooth ovaries (without follicle or corpus luteum) were considered as delayed pubertal. The overall incidence of delayed puberty was found to be 60.68 percent. The age-wise incidence of delayed puberty was recorded 76.00%, 45.00% and 55.55% in 2-3, 3-4 and more than 4 years of age, respectively which was higher (53.52%) in poor BCS (below 2) than above 2 (46.47%).
