| Summary: | The study of the link between genes controlling protein polymorphism and milk
performance traits of domestic animals has great economic importance from a
selection point of view, as it reduces the generation interval, leading to
increased productivity in livestock. The objective of this paper was to
establish the influence of genetic β -lactoglobulin polymorphism on the
quantity and quality of milk of the simmental breed in Serbiа. For the
research blood samples were taken from a total of 157 Simmental cows. The
genotypes of Simmental cows for β-lactoblobulin and their effect on
quantitative milk performance traits were determined using the PCR-RFLP
analysis. The variability of traits influenced by the genetic polymorphism
of β-lactoblobulin was statistically very highly significant (p <0.0001) for
milk yield in standard lactation and milk fat and protein yields, while it
showed no statistically significant variability (p> 0.05) for content of
milk fat and protein. The genotype cows achieved a 121 kg and 338 kg
increase in milk production compared to the BB genotype and AA genotype
cows, respectively. |
