Xinong Saanen dairy goat breed in China who characterized by large body size, high milk
yield, strong adaptation. However, few know that Xinong Saanen dairy goat is also one of
breeds with high litter size, with a kidding rate of 200% (Zheng, 1988). High litter size
contributes to goat production (meat and velvet). Hence, increase of litter size contributes to improve productivity in the goat industry. Research on litter size of Xinong Saanen goat is important to improve productivity of the goat industry and to get new knowledge on the
molecular mechanism and major genes influencing ovulation rate, an active area of research since 1980s. The objective of this work was to test the influence of two casein genes (CSN3 and CSN1S2) on the litter size of the Xinong Saanen goat. We are not aware of recent research related to the influence of milk protein polymorphism on goat litter size. The results indicate that CSN3 and CSN1S2 gene have significant effects on goat litter size. Significant gene effects of CSN3 and CSN1S2 on lambs possibly resulted from FecB (Fecundity Booroola) gene which is possibly linked to casein genes (Montgomory et al., 1994). Therefore, CSN3 gene and CSN1S2 gene can be regarded as effective molecular markers on litter size of goats. The results presented here should be confirmed with more data. |
