Innovative strategies for superovulation in cattle
Although superstimulatory protocols in cattle are usually initiated during mid-cycle, the elective control follicular wave emergence and ovulation have had a great impact on the application of on-farm embryo transfer. However, the most commonly used approach for the synchronization of follicular wave emergence involves the use of estradiol which cannot be used in many parts of the world. Theref...
متن کاملRecent advances in the superovulation in cattle.
The variability in the superovulatory response continues to be one of the most frustrating problems with embryo transfer in cattle. The removal of LH from pituitary extracts has tended to reduce the variability in response, and several studies involving the use of the purified porcine pituitary extract. Folltropin-V are reviewed. The major source of variability in the superovulatory response in...
متن کاملInter relationship between some routine semen evaluation parameters in Jersey X local hill cattle crossbred bulls
The present study was conducted with an objective of establishing a relationship between various routine semen evaluation parameters. Work was conducted at Sperm Station Palampur, Himachal Pradesh, on the semen from five Jersey X local hill cattle crossbred breeding bulls. A total of 40 ejaculates (8 from each bull), were analysed at five different stages of processing namely post dilution, pos...
متن کاملEffects of Morphine Dependency on the Ovarian Folliculogenesis Following Superovulation in Mice
Background: Opioids may affect hypothalamic GnRH secretion and Hypothalamic-Pituitary- Gonad axis, resulting in reproductive disturbances. Current study investigates the effects of morphine on structure of ovary following superovulalion through morphologic/morphometric studies. Methods: Twelve young female NMRI mice were allocated into treatment and control groups. Treatment group received oral...
متن کاملSuperovulation in cattle: practical aspects of gonadotropin treatment and insemination.
Embryo transfer (ET) in cattle has been used for the realisation of breeding programmes world-wide for more than 20 years. The efficiency of breeding technology, i.e. the breeding progress and costs, depends to a large extent on the results of superovulatory treatment and artificial insemination (A.I.). The results of this step are characterised by a high degree of variation. Numerous attempts ...
