ABSTRACT
Abu
Atiah EF, Said Abdel Ghaffar
AE, Nabil GM., Progesterone in milk and oestrone sulphate in whey for diagnosis of postpartum ovarian
activity and pregnancy in Camelus dromedaries. 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.
