Abstract

This paper investigates the effect of extruded rapeseed grain on production parameters, carcass and breast meat quality of broiler chicken. There were three levels mixture of extruded rapeseed grain and corn meal used included with 10, 15 and 20%. Rapeseed grain is extruded with corn meal in ratio of 50:50%. At the beginning of the fattening period, four groups with 75 day-old chicks of hybrid Ross 308 were formed in four replications. The experiment lasted for 42 days. At the end of the experimental period, eight chickens from each group were sacrificed for the purpose of testing the carcass quality and breast meat of broilers. Inclusion of various amounts of this mixture in the diet for broilers resulted in a statistically significant difference in body weight of chickens. At the end of the experiment, control group achieved body weight of 2115.80 g and the experimental groups in a row, 2018.17, 2036.49 and 2047.32 g respectively. Feed conversion was increased from 2.5 to 3.5% in groups with extruded rapeseed grain. Partial substitution of soybean meal with extruded rapeseed grains did not significantly affect the carcass quality of chickens, or the nutritional quality of breast meat.

Key words: Extruded rapeseed, feeding, chicken, carcass quality, meat quality.
