EFFECTS OF PLANTING DENSITY BROILERS AT EXTENSION, SEXING GROWING IN CELLS ON PRODUCTIVE PERFORMANCE

Highlights the problem of influence stocking density in cages broiler crosses «SK-61 3 Rus» and «Ross-308», separated by gender, on the productivity indicators at the extended fattening (7–8 weeks). Given productive indicators and biochemical analysis of muscle males and females compared crosses. Set the difference in body weight during the extended broiler crosses between the «SK-61 3 Rus» and «Ross-308», which was within 5,3–6,2 % (P < 0.05) in favor of the former. The average daily weight gain had the same dynamics. The cost of feed per unit of production at the extended broiler depended on their genotype. So, cockerels and hens cross «SK-61 3 Rus» on this indicator had values of 8.0 and 8.8 %, respectively, lower than the cocks and hens cross «Ross-308». On the content of histidine meat chickens cross «SK-61 3 Rus» in all the samples exceeded the meat cross” Ross-308 “on 34,4–37,1 %. By the sum of the content of linoleic and linolenic fatty acids poultry cross «SK-61 3 Rus» on 15,1–19,2 % higher than poultry cross «Ross-308». Thus, for large carcasses intended for downstream recommended in fattening cages domestic broiler cross «SK-61 3 Rus» and obtain good results, while the females grow to 8 males and – up to 7 weeks of age.
