Abstract

Were carried two chemical analyses of the breast muscles without skin in fattening-type chickens Ross 308. 12 chickens were used for chemical analysis after feeding 42 days of body weight 1800.0 g in two cycles. In the breast muscle without skin was content dry matter 25.95 and 25.87 g.100 g^-1, protein 24.47 and 23.82 g.100 g^-1, and fat 3.34, respectively 3.49 g.100 g^-¹. Differences in these parameters between cycles were not statistically significant (P>0.05). Broilers were randomly selected in the hall on the farm. In the hall was a deep litter and breeding technology Big Dutchman with automatic feeding, watering, and automatically set lighting and temperature regimes. During the fattening of chickens have been relationship with recommended microclimate conditions and the length of the hall light and ventilation. The concentration of broilers per square one meter was 27.22, respectively. 29.34 kg. Broilers consumed of feed ad libitum.
