Abstract


Buffalo is an important worldwide species in terms of milk and meat production as well as draft. The majorconstraints to full exploitation of the productive potential of buffalo are its inherent low reproductive efficiency due todelayed puberty, higher age at first calving, long post partum anoestrus period, long intercalving period, silent heatcoupled with poor expression of oestrus, seasonality in breeding and low conception rate. Reproductive cycles in buffaloare regulated by endocrine-neuroendocrine interactions between hypothalamic, gonadotropic, gonadal and otherhormones. To improve the buffalo reproductive efficiency, the investigation on endocrine aspects is useful to gain abetter knowledge of buffalo reproduction. This review is focused on the information available on various basic hormones(Melatonin, Progesterone (P4), Estradiol 17B (E2), Follicle stimulating hormone (FSH), Luteinizing hormone (LH)) and onnew hormones (Inhibin, Glycoproteins associated with pregnancy (PAGs), Leptin) related to reproductive function.
