研究了肥厚相关瘦素基因（lEP）的hini多态性，并对其与白种改良猪群体中重要的经济肉制品性状的关系进行了分析。96头母猪的PCr-rFlP基因分型数据显示，等位基因T和C的频率分别为0.71和0.29。GlM分析结果表明，LEP基因对平均日增重（ADG）有影响，但对背膘厚（ABF）和瘦肉（LM）无显著影响。LEP基因型与平均日增重之间存在极显著差异（P≤0.01），其中等位基因C与日增重增加相关。对所选动物脂肪组织中瘦素mrNa水平的统计分析表明，瘦素mrNa水平不受lep - hini基因型的影响。
The HinfI polymorphism in fatness related leptin gene (lEP) has been characterized and evaluated for its association with eco nomically important meat production traits in the population of White Improved pig breed. The data obtained from the PCr-rFlP genotyping of 96 sows indicate the frequencies of 0.71 and 0.29 for allele T and C, respectively. The results of GlM analysis demonstrate, that the LEP gene contributes to average daily gain (ADG) but no significant effect was shown in case of backfat thickness (ABF) and lean meat (LM). Highly significant differences (P ≤ 0.01) were found between LEP genotypes and aDG, where allele C is associated with increased daily gain.The statistical analysis of leptin mrNa levels in adipose tissue of selected animals demonstrates that leptin mrNa level is not altered by lEP-HinfI genotype.
