Abstract This study was investigated to determine the faecal volatiles, steroid hormones and their correlation with behavioural signs during oestrous cycle in sheep (Ovis aries). This experiment was monitored from pro-oestrous to met-oestrous phases for correlation of endocrine dependence biochemical constituents in faeces and blood to detection of oestrous biomarkers. Medroxyprogesterone acetate sponges were used for 8 days to bring uniformity of oestrus in sheep.
