Contents Ovulation rate and litter size are important reproduction traits in sheep and are of
high economic value. Reproduction traits typically have low to medium heritabilities and do …

Breeding for higher prolificacy may improve lamb production efficiency in semi-intensive and
intensive sheep-production systems. Crossbreeding of native breeds with exotic prolific …

The intactness of DNA is the keystone of genome-based clinical investigations, where rapid
molecular detection of life-threatening bacteria is largely dependent on the isolation of high …

BMPR-1B and GDF9 genes are well known due to their important effects on litter size and
mechanisms controlling ovulation rate in sheep. In the present study, polymorphisms of …

The objective of this study was to investigate association between GDF9 and BMP15 gene
polymorphism and litter size in fat-tailed sheep, a total of 97 mature ewes from four breeds …

Reproductive traits are extremely important to the goat industry because moderate increase
in litter size can lead to large profit. Traditional selection for improving litter size is difficult …

The exons 1, 2 and flanking region of growth differentiation factor 9 (GDF 9) gene in five
randomly selected does of Jining Grey, Boer and Liaoning Cashmere goats were amplified …

Background Genetic variants of the GDF9 gene were considered to be the potent gene
markers for improving fecundity traits in Egyptian sheep and goats. Also, these favorable …

The mutation types GDF9 S395F and S427R increase the ovulation rate in heterozygotes,
while the homozygous form leads to infertility. This study presents a meta-analysis of GDF9 …

The existence of major genes affecting fecundity in sheep flocks throughout the world has
been demonstrated. Three major genes whose mutations can increase ovulation rate have …
