Abstract：The experiment was to determine the effect of dietary protein on the expression of red wool color gene,body size index and wool production of Joda multiparous red sheep.A total of 42 adult Joda multiparous red sheep were selected for the feed utilization effect test,which were randomly divided into control group and experimental group,with three replicates in each group and seven sheep in each replicate.The crude protein content in the control group and experimental group feed as 12.5%and 13.5%,respectively.The mRNA expression differences of the STX17,LEF1 and BMP7 genes in skin tissues of Joda multiparous red sheep were determined by the fluorescence quantitative method,and the significant differences in data between the two groups were calculated by the independent sample t-test method.The results showed that compared with the control group,LEF1 mRNA expression in skin tissues of Joda multiparous red sheep in the experimental group was significantly increased(P<0.05).The body weight,body height,body length and chest circumference of Joda multiparous red sheep in the experimental group were significantly higher than those in the control group(P<0.05).The shearing weight of Joda multiparous red sheep in the experimental group was 32.17%higher than that in the control group(P<0.05),and the gross fat weight was 21.40%higher than that in the control group(P<0.05).The study indicates that under the experiment condition,the body size index,shearing weight and gross fat weight are positively correlated with the dietary protein content.
