Abstract
Purpose. The present study is pigs streschutlyvist the Large White and Poltava meat breeds. The aim of the study was to study the effect streschutlyvosti quality pork using DNA - tests. Stressensitivity pigs was determined by identifying mutant RYR1 allele halothane gene, which was isolated from the blood DNA. Methods.Study of stress sensitivity the quality of pork was conducted in terms of commodity loudspeakers in Poltava region and pig APV Institute of NAAS of Ukraine. DNA isolation was performed using blood cell reagent “Chelex – 100”. Results. It was found that in stress sensitivity pigs in response to the unfavorable conditions of increased muscle stiffness, caused by suffocation, skin flushing, pyrexia, expressed oppression. Pigs that have been exempted from the mutant gene that determines stress sensitivity had better meat quality parameters for such features as pH, color intensity, tenderness, loss during cooking, but the figure of “water retention capacity” was a little bit worse. Conclusions. Thus, one can conclude that pigs Poltava meaty breed had better quality meat because they were free of the mutant allele halotanovoho RYR1 gene that is responsible for streschutlyvist pigs.
