Onl J Vet Res., 22 (1): 71-82, 2018. Milk from 24 normal parturient camels was subjected to assays for progesterone and oestrone sulphate. Progesterone declined but whey oestrone sulphate increased during the 1st and 2nd postpartum estrus compared with levels found on days 7 and 15 after partus and day 10 after the 1st and 2nd mating. At day 30 and 45 after the last mate, progesterone increased in non-estrus camels compared with those in estrus whereas, whey oestrone sulphate did not vary. However, both hormones increased in pregnant camels compared with non-pregnant ones. During gestation, progesterone did not vary whereas whey oestrone sulphate increased to a maximum during the 6th month. Results suggest that progesterone in milk could be used determine early pregnancy in camels and 1st and 2nd postpartum estrus, 1st luteal phase and early pregnancy.
Key words: Progesterone, whey oestrone sulphate, milk, camels, pregnancy.
