Leptinreceptorgenepolymorphism and its relationship with functional traits in Baluchi sheep using PCR- SSCP


In this study of 70 Baluchi sheep blood sample collection and DNA extraction was performed by SSCP. The purpose of this study was to evaluate the effect of leptin receptor gene and its relationship with functional traits in Baluchi sheep. The results showed that the haplotype Type I, Type II, Type III mutated haplotype the fourth type of mutation was observed. Weaning weight compared to that between three and four there is no haplotype but the average weaning weight of all of them with a second haplotype statistically different. Seemed to mean sexual relationship with the physiological effects of male and female sex chromosome, especially "sexual hormones this can differ significantly between male and female lambs during the growth of the show. Twin lambs weighing more than two twins, twins and triplets are more, the difference is due to the characteristics of good nutrition and energy and nutrients by the mother during pregnancy and lactation animals. Generally, given that in most seasons sheep pastures are becoming a significant factor in increasing the growth traits not unexpected.
