Extruded rapeseed and rapeseed meal in nutrition of broilers.

This paper investigates the effect of extrusion of grain and rapeseed meal on production parameters, the carcass and meat quality of broilers chest. At the beginning of fattening, six groups with 75, day-old Ross 308 chicken hybrids were formed, with four repetitions. The control group was based on soybean meal and the experimental groups included three levels of extruded mixtures of rapeseed with corn 10, 15 and 20%, and two levels of extruded rapeseed meal 4 and 8%. The mixture is extruded in the ratio 50:50%. The experiment lasted 42 days. At the end of fattening period 8 chicks from each group were sacrificed for examination of quality of broiler’s carcass and chest meat. Inclusion of extruded mixture in nutrition resulted in highly significant differences in body mass of chicks (P 0.05). Changes in nutrition of chickens had no influence (P> 0.05) on the nutritional quality of chest meat.
