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 کاملEffect of selection for litter size and body weight on hormone-induced ovulation rate in mice.
Genetic differences in natural vs hormone-induced ovulation rates were compared in immature female mice from five lines that had undergone long-term single-trait and antagonistic index selection for litter size and(or) 6-wk BW. Lines used were control (K); high litter size (L+); high BW (W+); low litter size and high BW (L-W+); and high litter size and low BW (L+W-). Natural ovulation rate at a...
متن کاملPolymorphisms in GDF9 Gene and Its Relationship with Litter Size in Five Breeds of Black Goats
In this study, we investigated the relationship between the genetic polymorphism of growth differentiation factor 9 (GDF9) genes and the litter size in 384 individuals of five breeds of black goats. Four pairs of primers were designed to detect single nucleotide polymorphism of GDF9 gene in goats by PCR-SSCP. The least square was used to analyze the relation between different genotypes and the ...
متن کاملOvulation rate in sheep selected for weaning weight or litter size.
Ovulation rate was measured by laparoscopy at two consecutive cycles on 366 ewes 2 yr old and over and 85 yearling ewes of five lines of Targhees from the base base population; 53 yearling linecross ewes were also included. The lines were two unselected controls (HCl and DC), two selected for 21 yr for increased 120-d weight (HW and DH) and one selected for 19 yr for multiple births (T). Ewes w...
