ABSTRACT
Asgari Safdar AH., Effect
of calcium salt of palm oil, gonadotrophins, selenium, vitamin E and B12
supplement on reproductive performance in uni and
multiparous ewes. Onl J Vet Res., 23 (5):395-406,
2019. Twenty uniparous and multiparous
48-50kg 3-4 year old ewes were fed a basal diet supplemented
6% calcium salt of palm oil and injected 500IU human chorionic gonadotrophin
(HCG) intramuscularly. Another 20 ewes were given selenium, injected vitamin E
and B12 with equine chorionic gonadotrophin (ECG). Ten control ewes were fed
basal diet. Estrus was then synchronized by intravaginal progesterone controlled
release (CIDR). Thirty six hours after CIDR removal ewes were bred with rams. Blood
was taken for determination of insulin, glucose, estrogen, progesterone and
cholesterol 24 hours before and after CIDR removal, and 14 days after breeding.
Compared with controls, we found higher (P < 0.05) fertility and lambing in
ewes given supplements and gonadotrophins with higher levels of estrogen,
progesterone, and insulin after flushing.
