Polymorphism of caprine SLC11A1 gene and relationships with hygienic characteristics of milk

"\"Th e solute carrier family 11 member A1 (SLC11A1) gene is associated with resistance. to infectious diseases. Genetic variability at the 3’ untranslated region (3’-UTR) of. this gene is due to the presence of a polymorphic microsatellites that contain a (GT) n. dinucleotide repeat. Th e microsatellite variability and relationships with milk yield. and composition, somatic cell count (SCC) and total microbic count (TMC) were investigated. in 260 goats of Sarda breed. Genotyping of the upstream guanine-thymine. repeat (GT)n revealed twenty diff erent genotypes and eight alleles (GT11, GT12,. GT14, GT15, GT16, GT17, GT18 and GT19). Th e present study confi rmed the high genetic. variability of the Sarda goat and that the genotype of the microsatellite at. 3’-UTR SLC11A1 aff ected many chemical and hygienic characteristics of milk as fat,. protein and SCC\""
