The effect of amaranth as a resource of proteins on the growth, carcass characteristics and meat quality of broiler chickens was assessed in a feeding trial. Experimental animals were fed compound feeds with either crude amaranth grain (AC) or heat processed amaranth grain (AP) or dried above-ground biomass (AB). Control animals (C) received a diet containing animal proteins. There were no significant differences between the groups studied. On day 42 of the experiment, live weight of female broilers ranged from 2,205.1+/-152.5 g (AP) to 2,254.0+/-136.5 g (C), and that of male broilers from 2,375.1+/-233.0 g (AC) to 2,506.0+/-286.0 g (C). Feed conversion efficiency ranged from 1.80 kg in C male chickens to 1.91 kg in AB male chickens. Carcass yield ranged from 70.8+/-1.74% (AB) to 72.4+/-3.34% (AC) or 72.4+/-1.98% (C) in females, and from 72.8+/-3.55% (AP) to 75.1+/-2.44% (AB) in males. Amaranth can fully replace meat-and-bone meals in the diets for broiler chickens.
