In the experimental conditions production efficiency of commercial feed-mix for broiler chickens feeding on three hybrids (Ross, Vedette, Hybro) was tested. Feed-mix were analysed for protein and amino acid content, and energetic value. In the experiment were used HYD-01, HYD-02 (loose and granulated) and HYD-03 (granulated) mixtures. According to the analysis there were deficiencies in protein content as well as in aminoacids and energy value. This deficit was negatively demonstrated on final live weight of chickens at the age of 44 days, when the chickens reached lower weigh of 55-330 g in relation to quaranted values. Even the composition of feeds for kilogramm of gain was higher, especially in the starting period. In this period was recorded the highest defficiency differencies in content of nutrients from the recommendation. From statistical analysis came out, that among chicken hybrid combinations was found a different intensity of growth in relation to intake of lysin and energy in different stage of feeding. The best growth was achieved by Hybro chickens in comparison to Vedette and Ross chicken the differences climbed to the border of statistical significancy. In no case chicken weight have achieved the weight declared and quaranted by breeders. Chicken of Ross were 1550 g in weight, chicken of Vedette achieved 1540 g and Hybro 1650 g at the age of 44 days. The feed consumption per kg were 2.15-2.34 kg (in the same order of groups)
