The Effect of Active Immunization against Inhibin and of Fsh Supplementation on Ovulation Rate in Heifers
Inhibin is released during late prophase by suppressing the FSH secretion without affecting LH secretion. Immunization against inhibin will increase FSH synthesis leading to ovulation rate. As both immunization against inhibin and FSH injection could increase ovulation rate, therefore, an interaction of both treatment should act synergically or addively. Immunized group (n=10) were immunized wi...
متن کاملOvarian and hormonal response of female goats to active immunization against inhibin.
This study was conducted to evaluate the effect of active immunization against inhibin on hormonal levels and the ovulation rate in goats. Ten adult Shiba goats (Capra hircus) in two groups were used in this study. The first group was injected with inhibin vaccine (immunized, n=5) and the second group was injected with Freund's adjuvant (control, n=5) followed by three booster injections at 4-w...
متن کاملDevelopment of embryos in superovulated guinea pigs following active immunization against the inhibin alpha-subunit.
Embryo recovery and subsequent embryonic development from guinea pigs treated with or without inhibin vaccines were compared to determine the effect of active immunization against the inhibin alpha-subunit. Twenty female guinea pigs of the Hartley strain were injected 3 times either with 1 ml inhibin vaccine (recombinant ovine inhibin a-subunit in oil emulsion: 50 microg/ml, inhibin-immunized g...
متن کاملPituitary and testicular responses of beef bulls to active immunization against inhibin alpha.
Prepubertal crossbred beef bulls served as controls or were actively immunized against the N-terminal, 30-amino acid synthetic fragment of porcine inhibin alpha, pI alpha (1-30). Antibody titers were detected in sera (greater than 40% B/BO in sera diluted 1,000-fold) but not in rete testis fluid of 390-d-old bulls. Serum FSH and inhibin remained static during a 5-h intensive bleed; inhibin was ...
متن کاملActive Immunization against Poliomyelitis
1. A single intracutaneous inoculation with a subinfective dose of the virus of poliomyelitis produces considerable immunity. 2. Virus-serum combinations produce an appreciable immunity, providing just sufficient serum is used to protect the animal from paralysis. If there is an excess of serum, the degree of immunity is considerably reduced.
