Detection of MC4R Gene Genotypes and A Relationship SNP13 to Productive and Reproductive Performance in Iraqi Local Goats and Shami Goats

Abstract

Abstract The study was conducted at the Ruminant Research Station of the Agricultural Research Department / Ministry of Agriculture, for the period from 1/12/2021 - 30/10/2022, the current study revealed the relationship between the genotypes of the MC4R gene and its relationship with the productive and reproductive traits in goats. Using 50 goats under the same breeding conditions (25 Syrian goats and 25 Iraqi goats). The results showed that the 13SNP mutation in the MC4R gene in the mothers of Shami goats showed a significant relationship, where the genotype GA was significantly (P≤0.05) superior to the genotype GG in this strain for the characteristic of the daily milk production rate (kg), as well as for the characteristic of the length of the peak of production (day), as well as the characteristic of the percentage of protein in milk (%), and the characteristic of the weight gain of the mother between birth and weaning, with an average of (541.07, 426.76), (43.01, 34.17), (3.16, 3.01), respectively. Conclusion it is the Mutations in genetic and environmental factors play an essential role in livestock animals in terms of productive and economic traits. Thus, the effects of mutations in the MC4R gene were found to have an impact on some productive and reproductive traits in goats.
