Relationship of FABP2 (-561A> C) gene polymorphism with abdominal fat content in сhickens of meat poultry production

Poultry farming is one of the most dynamic, highly developed and knowledge-intensive branches of domestic livestock production. In recent years, in the meat balance the poultry meat level has reached more than 33% in the world and 40% in Russia, especially by means of growing chicken broilers. At the same time, it has become evident that the lipid nutritional value of poultry meat needs correction in order to increase its biological value. About 15-20% of the modern broiler carcass is fat.

Influence of various diets on association of polymorphism in MSTN gene and live weight increase in young cockerels of pushkin breed

The effect of different diets on the growth rate of Pushkin breed cockerels depending on the genotype in substitution of rs313744840 in the myostatin gene has been analyzed. In cockerels grown on feed for broilers (n = 52) the AG heterozygotes have had the biggest weigh gain, which began to differ significantly (p <0.05) from their peers from the 14th day of life. In cockerels grown on feed for young laying hens (n = 46) the AA homozygotes have had an advantage in growth, but the difference between the groups has proved to be unreliable.
