Follicular development in heifers infused with follicle-stimulating hormone.
Follicle-stimulating hormone from different species has been used to increase ovulation and calving rates in cattle, injections proving to be most successful when given during the late follicular phase of the oestrous cycle or in combination with progestagens (Willett & Buckner, 1953; Bellows, Anderson & Short 1969). Some investigations have resulted in substantial increases in ovulation and ca...
متن کاملFollicular characteristics and luteal development after follicle-stimulating hormone induced multiple ovulations in heifers.
A protocol based on small doses of FSH was examined for the induction of double or triple (multiple) ovulations in cattle. Ovulation rate, follicular characteristics, and luteal responses were determined. In Exp. 1, three groups of estrous-synchronized, cyclic Holstein heifers were treated once daily, on d 3 to 6 of the cycle, with a FSH product (Folltropin-V): large FSH dose (total of 150 mg; ...
متن کاملO-20: The Combination of Basic Fibroblast Growth Factor and Follicular Stimulating Hormone Promotes Human Follicle Development In Vitro Culture
Background Fertility preservation is an important part of scientific study in the field of reproductive medicine. Ovarian cryopreservation and in vitro follicles culture provide option for fertility conservation in older women or cancer patients. Basic fibroblast growth factor (bFGF) or FGF-2, is member of fibroblast growth factors family which play critical roles in cell migration proliferatio...
متن کاملOvarian follicular characteristics, embryo recovery, and embryo viability in heifers fed high-fat diets and treated with follicle-stimulating hormone.
Postpubertal beef heifers (n = 55) were used to examine the effects of high-fat diets, independently of energy intake, on nonesterified fatty acid and lipoprotein metabolic patterns, ovarian follicular dynamics, and embryo recovery/viability after FSH superstimulation. High-lipid (HL) diets (5.4% added fat) increased (P < .01) serum concentrations of cholesterol, but not of nonesterified fatty ...
متن کاملSuperstimulation of Follicular Growth in Thai Native Heifers by a Single Administration of Follicle Stimulating Hormone Dissolved in Polyvinylpyrrolidone
This study was undertaken to determine whether a single i.m. injection of FSH dissolved in 10 ml of 30% (wt/vol) polyvinylpyrrolidone (PVP; MW=40,000) to form FSHp would induce follicular growth in Thai native heifers and to determine its optimal dose. In Group 1, heifers (n=4) were given multiple i.m. injections of FSHp every 12 h for 3 days at decreasing doses, for a total of 100 mg (control)...
