Research note: The effects of genotype, sex, and feeding regime on performance, carcasses characteristic, and microbiota in chickens
Original language description
The aim of the present study was to evaluate the effects of quantitative feed restriction (FR) in fast, medium, and slowgrowing meat-type male and female chickens on their growth, feed consumption, economic efficiency, carcass composition, and gastrointestinal microbiota. In the experiment, fast-growing Ross 308, medium-growing Hubbard JA 757 and slow-growing ISA Dual chickens of both sexes were exposed to quantitative FR between 14 and 21 d of age. During the FR, restricted chickens received 70% of the amount of feed consumed by the ad libitum (AL) group. Live weight at the end of the experiment was affected by genotype (P lower than 0,001), sex (P lower than 0,001), feeding regime (P lower than 0,001), and their interaction (P lower than 0,001). The highest final weight was in AL and FR ISA Dual males and the lowest was in AL and FR females of the same genotype. A similar tendency was observed in daily weight gain and feed intake. Carcass traits were predominantly affected by genotype. However, int
