Leptin Receptor gene -Awasi sheep-Production traits.Abstract
This study had been conducted in the First Research Station for Agriculture College Muthana University and the laboratory of biological technique & practical analysis - Ministry of Science and Technology through the period 1/11/2015 to 1/07/2016. The aims of this study was to determine the genetic components of Leptin receptore gene and explore the relationship of these components with a some of production for local Awasi sheep. The genotype distribution ratios had been contrasted TT, TV and VV for Leptin gene receptor (LEPR) significantly (P<0.01) in the studied sample, where there ratios had reached 8.33, 55.00 and 36.67% in series with allele frequency was 0.36 and 0.64 for each T and V allele in series. The current study results showed that the total milk production and milk season duration period for Awasi sheep had been significantly influenced (P<0.05) by genotype for LPR gene and for the sheep that had structure VV for milk and for TT genotype was the milk season duration. The studied milk component ratio had not been influenced by the variation of genotype except for fate ratio. It can be concluded through the study of the genotype of Leptin gene and its future it adoption to set the genetic rehabilitation strategies for sheep to maximize their economic income of sheep genotype selection and interaction breading projects which already achieved best economic parameters, Additionally, the application of this study on larger sample for many production seasons can give more accurate results to adopt exclusion and replacement strategy.
