摘要: Abstract A variable TG-repeat polymorphism was found in the goat growth hormone receptor (GHR) gene 5′-noncoding region. In total 235 goats belonging to two dairy breeds were genotyped, 10 alleles of GHR detected. The length repeat region variants (alleles) from 305 346 bp. Among identified, eight occurred homozygous systems. frequency genotypes 0.25 for Polish White Improved breed and 0.28 Fawn breed. mean heterozygosity (H) polymorphic content coefficients (PIC) at this locus similar both breeds. association studied with milk production traits 157 using REML method repeatability, multi-traits Animal Test-Day Model. No associations traits—milk yield major components (fat, protein, lactose). Also, no effect shown genotype on somatic cell count (SCC).
