A Consumer Study of the Eating Quality of Broiler Chickens Fed Rations Containing Low Glucosinolate Rapeseed Meal and Rapeseed Screenings Meal

Abstract

The eating quality of 8-week-old White Mountain × Hubbard broiler chickens fed four (Commercial-type) rations was evaluated by 110 consumer panelists. The rations were a soybean meal control ration (SBM), a 10% Tower rapeseed meal ration (RSM), a soybean meal ration with 10% rapeseed screenings meal (SBM + 10 RSSM), and a Tower rapeseed meal ration with 10% rapeseed screenings meal (RSM + 10 RSSM). Panelists received four coded frozen half chickens (one representing each ration treatment) and were instructed how to cook each defrosted chicken half. Consumer panelists scored the odor, flavor, and overall acceptability of the chickens and then ranked the chickens in order of preference. There were no significant differences in the odor, flavor, and overall acceptability of the cooked chickens attributable to ration. Mean scores given to each of the rations for preference rating of the cooked chickens show they were similar in eating quality, suggesting that the eating quality of chickens was not affected by the inclusion of 10% Tower rapeseed meal in the ration. Inclusion of 10% rapeseed screenings meal in either the SBM or RSM ration also had no effect on the eating quality of the broilers.
