Genetic diversity of chinese pig breed in different ecological environment

Abstract

Abstract: The relationships between gene frequency of the serum protein loci Tf, Am, Pa and Cp of some local pig breeds in china and ecological environment, and their variation patterns were studied by least square analysis. There were 3 alleles at Tf, Am, and Cp loci, respectively, and 2 alleles at Pa locus. The gene frequencies among6 geographical pig types and among8 ecological areas varied significantly (p<0.05), indicating that the effects of geographical type and ecological environment on the gene frequency and heterozygosity were obvious. Dongting Hong Lake area, Xianjiang River Poyang Lake area, and Taihu Lake area could be regarded as the starting point of up and downward frequency in chinese pig breeds.
