EFFECT OF DIFFERENT LEVELS OF NUTRITION ON THE EFFECTIVENESS OF INTERMEDIATE EXCHANGE ^{[№ 6 ' 2014]}
The paper presents data on the effect of phytase on the exchange of energy, nitrogen and productivity of broiler chickens at various NUTRIENT security. Found that in groups with fitazosoderzhaschim diet is a decrease of energy losses with the droppings on the background of increasing KPI OE and matching coefficient, which indicates the rational use of energy for the synthesis of tissues.

USING PCR FOR GENOTYPING CATTLE CAPN1 THE GENE USING GENETIC MARKERS ^{[№ 6 ' 2012]}
The paper presents results of experimental studies on the use of DNA technology in farming, on the basis of molecular genetic techniques that allow the testing of animals of any age and gender, to assess and predict their productivity. Revealed that the SS is the most desirable form of the gene allele CAPN1, responsible for the formation of the tenderness of meat.

EFFECT OF PHYTASE ON MORPHOFUNCTIONAL STATE OF INTESTINAL OF BROILER CHICKENS AT DIFFERENT LEVELS OF PHOSPHORUS IN THE DIET ^{[№ 6 ' 2012]}
The paper presents results of experimental studies on the morphofunctional stateof the intestine of the experimental birds by using an enzyme preparation RonozimNT (CT) at different levels of phosphorus in the diet. Histological analysis ofintestine (thin section) confirms the positive effect of the drug Ronozim NT (CT) on the morphological characteristics of the mucosal relief of the small intestine of broiler chickens.
