Sažetak
This research aimed at investigation of growth phases of male broilers and establishment of qualitative characteristics of carcasses, as well as of chemical content of breast muscles and thighs. The research was carried out on 45 male broilers of Ross 208 provenience, which were divided into 3 groups. Broilers were fed with starter and finisher diets containing 22.67%/20.43% of crude proteins and 14.19 MJ/kg/14.18 MJ/kg ME, respectively. After 35 days of fattening broilers gained weight of 2065.75 ± ; ; ; 100.36 g. Asymmetric S-function was used for estimation of the growth phases, and parameters of the used model were the following: A=3.8 kg, b=1.41969, c=2.69601 and g=0.18. Average weight of carcasses was 1815± ; ; ; 25 g. Portions in the whole carcass were as follows: breasts 33.75%, thighs with drumsticks 30.35%, wings 11.15% and backs 22.40%. Breast muscles differed statistically (P<0.05) than thigh muscles in the content of proteins (23.03% : 19.42%), fats (1.32% : 4.51%) and ashes (1.23% : 1.10%). Breast muscles contained more SFA (39.48% : 33.83%) and PUFA n-3 (6.02% : 3.71%), but less MUFA (29.61% : 35.63%) and PUFA n-6 (17.70% : 19.85%) when compared to the thigh muscles. Ratio PUFA n-6 / PUFA n-3 was better in the breast muscles than in the thighs.
