The incidence of delayed puberty was studied in 500 cattle heifers in and around Jabalpur. The heifers with history of non-exhibition of estrus and smooth ovaries (without follicles or corpus luteum) during gynaecological examination were considered as delayed pubertal. The overall incidence of delayed puberty was found 44.44%. The analysis of result on breed wise incidence revealed 52.92%, 29.21%, 57.89% and 41.67% in non-descript, crossbred, Gir and Sahiwal breeds, respectively. The results revealed higher incidence of delayed puberty (68.92%) in heifers with body condition score (BCS) below 2 as compared to BCS more than 2 (31.08%). It can be concluded from this study that delayed puberty is one of the cause of anoestrus and thus prolonged calving interval in rural cattle. Further, higher incidence of delayed puberty persists in indigenous and nondescript rural cattle heifers of poor body condition score.
