Processing Yields and Meat Flavor of Broilers Fed a Mixture of Narasin and Nicarbazin as an Anticoccidial Agent

Processed yields (percent hot carcass) and cooked meat flavor of broilers fed 100 ppm of an anticoccidial agent (a mixture of 50 ppm narasin and 50 ppm nicarbazin) were compared with yields of birds fed a ration without the anticoccidial agent. Broilers were processed at 7 wk of age (49 days) after a 4-day withdrawal from the anticoccidial agent for the treated birds. The flavor of meat was evaluated by a 12-member sensory panel. Meat was either deep fat-fried or oven roasted. Sensory evaluations were made on freshly cooked samples and on cooked meat refrigerated for 24 h and reheated. The anticoccidial agent did not produce a difference (P greater than .05) in the hot carcass yields of the broilers as compared with control birds fed the nonmedicated diet. Analyses of triangle test data for flavor evaluations by two statistical methods indicated that there were no detectable differences (P greater than .05) in flavor between broilers fed the anticoccidial agent in the diet and those fed the control diet.
