Synchronization of Oestrus in Cattle, Sheep and Goats Using a Prostaglandin Analogue
Prostaglandin F~(Y, (PGF2a) causes luteolysis in several species of animals including cattle and sheep. This has led to investigations with PGF2a as an agent for the control of oestrus and ovulation in domestic animals (Inskeep 1973) and to comparison of PGF2a and progestins as practical methods of synchronizing oestrus in cattle (Smith 1973). This paper reports preliminary studies of the use o...

متن کاملSynchronization of parturition in beef cattle with prostaglandin and dexamethasone.
The effectiveness of dexamethasone and prostaglandin in combination for induction and synchronization of parturition in cattle was evaluated in 100 pregnant Angus, Hereford, Charolais and Simmental cows. Cows were distributed equally by breed, day of gestation and cow age to one of three treatments: 1) Control, 2) Dexamethasone (25 mg) plus prostaglandin F(2alpha) (25 mg) or 3) Dexamethasone (2...

متن کاملComparison of Different Methods of Oestrus Synchronization on Reproductive Performance of Farahani Sheep in Iran
This experiment was carried out on 123 Farahani ewes from a herd in Delijan city in Markazi province of Iran to determine the best short-term method for oestrus synchronization. Ewes were divided into five experimental groups randomly: group 1) use of controlled intervaginal drug release devices (CIDR) for 7 days with intramuscular (IM) injection of PGF2α on zero day and IM injection of 500 IU ...
