Influence of Lipoprotein lipase (LPL) gene polymorphism on production traits in dairy goats

Abstract

The objective of this study was to investigate the influence of LPL gene polymorphism on production traits in dairy goats. Materials and Methods. The polymorphism of the goat was analysed in 272 unrelated individuals belonging to three pure goat breeds (Saanen, n=104; Anglo Nubian (Fig. 2), n=88 and Alpine, n=80) (Fig. 1) in Lithuania. All investigated goats were raised in the same feeding and housing conditions. Milk yields were recorded by monthly control milking during the period of 2018-2019. The milk samples were analysed for milk fat, milk protein, lactose and urea concentrations. The analysis was carried out using spectrophotometers LactoScope 550 andLactoScope FTIR (Delta Instruments, the Netherlands). The somatic cell count (SCC) in milk was determined by flow cytometry method using the Somascope CA-3A4 (Delta Instruments, The Netherlands). The method of polymerase chain reaction and restriction length polymorphism were used to genotype the LPL gene G50C polymorphism. [...].
