متن کاملOvarian response and conception rate following oestrus synchronization using three protocols in Egyptian buffalo heifers.
OBJECTIVE The aim of this study was to monitor the ovarian response and conception rate following estrous synchronization using CIDR, Ovsynch and double prostaglandin F2α protocols in Egyptian buffalo heifers. MATERIAL AND METHODS A total of 80 cyclic buffalo heifers were divided into four equal groups: CIDR (intravaginal progesterone releasing device, EAZI-BREEDTM CIDR®), Ovsynch (GnRH, PGF2...
متن کاملSynchronization 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 کاملPregnancy Rates in Repeat-breeder Heifers Following Multiple Artificial Inseminations during Spontaneous Oestrus
Hormonal asynchronies during oestrus, related to the presence of suprabasal plasma-progesterone (P4) concentrations and a delayed ovulation, interfere with the fertility of repeat-breeder heifers (RBH). Since tubal dysfunction can occur in connection with hormonal asynchronies and constrained availability of fertile spermatozoa at the time of ovulation, the present study tested the hypothesis t...
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 ...
