The Relation of IGF-1 Genotype with Weight in Etawah Grade Goats at Polewali Mandar Regency

Abstract

A study was conducted to the relation of IGF-1 genotype with weight in Etawah Grade goats at Polewali Mandar Regency. The object of this research used 22 Etawah Grade goats that had been weighed and their blood was taken for DNA and PCR-RFLP extraction to determine the diversity of the IGF-1 genotype. The data then calculated the allele frequency and genotype frequency, a simple linear regression analyis, the correlation coefficient, and the coefficient of determination. The research results obtained were that AA, AB, and BB genotypes of IGF-1 gene with the most allele frequency and genotype frequency is allele A and AB genotype, simple linear regression equation Y = 15,46 + 4,53X with a correlation coefficient of 0,67 and a coefficient of determination is 0,42. It was concluded that there was a strong the relationship of IGF-1 genotype diversity with weight in Etawah Grade goats.
