Abu Atiah EF, Abdel Ghaffar AES, Nabil GM., Milk Progesterone and whey oestrone sulphate for diagnosis of postpartum ovarian activity and pregnancy in camels (Camelus dromedarius), Onl J Vet Res., 22 (5):425-433, 2018. Twenty four normal parturient camels were subjected to assay of milk progesterone and whey oestrone sulphate. Results showed significant (P< 0.05) reductions in milk progesterone and rises in whey oestrone sulphate during the 1st and 2nd postpartum estrus compared with days 7 and 15 after parturition and 10 days after the 1st and 2nd breeding. By days 30 and 45 after the last breeding milk progesterone increased in camels without heat compared with those in heat. However, milk whey oestrone sulphate did not vary significantly between any group. Milk progesterone and whey oestrone sulphate increased in pregnant camels compared with non-pregnant ones. As gestation progressed, the concentration of progesterone in milk did not vary whereas whey oestrone sulphate increased to a maximum at 6 months of pregnancy. We surmise that milk progesterone with whey oestrone could be used to diagnose 1st and 2nd postpartum estrus, 1st luteal phase and early pregnancy. Our findings suggest that milk progesterone and whey oestrone sulphate may reflect postpartum ovarian activity in camels.
