STUDY FOR FECB AND GDF9 AS CANDIDATE GENES FOR PROLIFICACY OF TWO TYPES OF CROSSBREED SHEEP
Litter size is an important economic trait in sheep breeding and reproduction. It has been reported that the FecB gene mutation was responsible for the high prolific acyassociatedin Booroola Merino sheep and growth differentiation factor (GDF9) control the fecundity of Belclare and Cambridge ewes. FecB gene can affect the number of ovulation. GDF9 is a growth factor secreted by oocytes in growthing ovarian follicles, which is essential for growth and differentiation of early ovarian follicles. FecB gene and GDF9 gene were studied as candidate genes on the prolificacy of Sheep. The aim of this experiment was in crossbreeds of Small-tails Sheep×Tan Sheep×Germany Merino Sheep and Small-tails Sheep×Tan Sheep×Dorset Sheep to study FecB gene and GDF9 gene as candidate genes on the prolificacy of two types of crossbreed sheep so that it will be provided scientific support for breeding new breed of China mutton sheep.
