Abstract
Puberty in females is described as the attainment of a developmental stage that allows for normal ovarian cyclicity (follicular development and ovulation) and the potential to get pregnant. Delayed puberty is one of the major reproductive disorders seen under organized and unorganized rearing conditions, especially due to poor body condition score animals. So, the study was conducted for the incidence of delayed puberty in cattle heifers. The incidence of delayed puberty was studied in 107 cattle heifers in and around Jabalpur, Madhya Pradesh. The age, body weight and body condition score (2-4 out of 5 scale) was recorded. The suspected delayed pubertal heifers were examined per rectally to ascertain the ovarian function i.e., the presence of follicles or corpus luteum. The heifers with a history of non-exhibition of oestrus since birth and smooth ovaries (without palpable follicles or corpus luteum) in two consecutive gynaecological examinations at 10 days apart were considered as delayed pubertal animals. The incidence of delayed puberty was studied in 107 cattle heifers and 53 were found to be delayed pubertal. The overall incidence of delayed puberty was found 49.53 per cent, however, the breed-wise incidence was found 47.82%, 46.15%, 57.17%, and 48.64% in Non-descript, Sahiwal, Gir and Crossbred heifers, respectively.
