Modern broiler production is based on exploitation of meat type hybrids which are characterized by intensive growth, excellent food efficiency, strong constitution and excellent body conformation. In Serbia, many foreign proveniences are present and therefore there is a need to define a hybrid which in existing production conditions would realize the best fattening results. Objective of the study was to determine the production results of two most present line hybrids on our market, Cobb-500 and Ross-308. The following production parameters: body mass, gain, feed consumption, feed conversion, mortality and production index were monitored. One day old chickens were distributed randomly in two groups with 4 repetitions per each hybrid. In nutrition of broilers complete pellet mixtures were used, which ensured that all broiler requirements in energy, proteins, mineral substances, vitamins and essential amino acids were met. Higher final body mass was realized by Ross-308. In regard to feed conversion, mortality, feed consumption and value of production index, it is observed that Cobb-500 broilers realized better feed conversion (1,78), lower mortality (7,00%), lower consumption of feed per chicken (4238g) and higher value of production index with 316 index points compared to Ross-308 (1.82; 9,00%; 4407g; 309). Obtained production indexes for both hybrids were very high, so it can be concluded that there are no statistically significant differences between these two hybrids. It can be concluded that achieved results are satisfactory, and that hybrids have high genetic potential.
