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 BMPRIB gene is one of the main genes that can be used as a molecular genetic marker
for the early selection of highly productive ewes. It is well-documented that the p. Q249R (g …

Simple Summary GDF9 and BMPR1B are two important reproduction genes. In this study,
the whole coding region of GDF9 was sequenced, of which the mutations were detected in …

Sheep were one of the earliest domesticated animals. Both artificial and natural selection
during domestication has resulted in remarkable changes in behavioral, physiological, and …

Reproductive performance is a complex quantitative trait, that is determined by multiple
genes, regulatory pathways and environmental factors. A list of major genes with large effect …

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 …

Litter size is one of the crucial factors in livestock production and is of high economic value,
which is affected by ovulation rate, hormones, and growth factors. Growth factors play a …

Background As an important reproductive hormone, melatonin plays an important role in
regulating the reproductive activities of sheep and other mammals. Hu sheep is a breed …

Simple Summary Increasing litter size is critical for the intensive sheep production system.
Genetic marker-assisted selection (MAS) based on proven molecular indicators could …

The aim of this study was to investigate the selection signatures at a genome-wide level in
'Pishan'sheep using Specific Locus Amplified Fragment (SLAF)-seq. Blood samples from …
