Abstract

An experiment was conducted to compare the responses of young broiler chickens to corn-soybean meal diets supplemented with flaxseed or camelina meal versus a corn-soybean meal control and the factorial effect of 150 mg/kg of Cu supplementation on per-formance and processing yield. A randomized complete block design with a 2 × 3 factorial arrangement was used with 7 replicates from hatch to 21 d of age (n = 294; 7 chicks per replicate). Body weight of birds fed 10% camelina meal or 10% flaxseed was significantly reduced compared with the control birds. Addition of Cu significantly increased BW and feed consumption of the birds fed the control diet throughout the study. Copper supplementation to the 10% camelina meal diet also increased BW (P < 0.001) with no effect on feed consumption or feed conversion at 21 d. In addition, hot carcass weight, yield, and carcass parts were significantly improved among birds fed the Cu-supplemented control diet. A significant Cu × diet interaction was observed for hot carcass weight and yield, indicating Cu supplementation to the control diet was superior for carcass weight to the other treatments. However, yield was greater for the camelina diets and the control + Cu versus the other treatments. Results from the present study demonstrated that either 10% camelina meal or 10% flaxseed diets will reduce broiler BW when fed the first 3 wk of life. However, birds fed the cameli-na diet responded to Cu sulfate supplementation with improved live performance and carcass characteristics. Birds fed the 10% flaxseed diets showed no beneficial effect resulting from Cu supplements.
