Associations of SREBP1 Gene polymorphisms with fatty acid composition in Simmental
The aim was to investigate the effect of the genetic polymorphisms of sterol regulatory element binding fac- tor 1（SREBP1） gene on the fatty acid （FA） composition of the muscle of 165 Simmental bulls. The polymorphisms in the intron 5 of bovine SREBP1 was genotyped by PCR to investigate the association. The results showed that the 84bp indel mutation in intron 5 was significantly associated with palmitc acid（C16：1）, stearic acid（C18：0） ,oleic acid （C18 ： 1）, SFA, triglycerides, C16 index. Cattle with LL genotype had higher palmitc acid （C16 ： 1）, triglycerides and C16 index than those of the LS genotype,on the contrary,lower stearic acid（C18：0） and SFA than LS genotype.
