摘　　要：用PCR-RFLP法对13 头大约克母猪的RYR1 基因分型。用数学模型分析3 种基因型的82 头仔猪生长发育情况,发现仔猪正常生长规律符合指数模型, 断奶到断奶应激结束时间内的生长符合二次多项式模型。RYR1NN 型母猪所产仔猪从初生到65 日龄的体重均显著低于RYR1Nn和RYR1nn型母猪的仔猪(P< 0.05)。3 种基因型母猪的仔猪间断奶应激差异不显著(P> 0.05)。A total of 13 Large White sows were genotyped for ryanodine receptor gene by PCR RFLP.Mathematics models were established to analyze the growth and development of 82 piglets from three genotypes of sows.The piglets grew at exponential pattern in their early stage and at binomial model during weaning stage.The results indicated that piglets from sows with genotype RYR1 Nn or RYR1 nn grew faster than those from sows with genotype RYR1 NN (P<0 05).The weaning stress values had not significant difference between genotypes(P>0 05).
