Abstract
Effects of standardized ileal digestible lysine level and added tribasic copper chloride on growth performance, carcass characteristics, and economics in finishing pigs (2014)
Highlights
Past experiments have suggested that feeding supplemental copper (Cu) in the form of copper sulfate (CuSO4) did not provide growth benefits beyond 135 lb (Hastad et al, 20014)
All diets were corn-soybean meal–based with 30% dried distillers grains with solubles (DDGS) and contained 17 ppm of Cu from copper sulfate (CuSO4) provided by the trace mineral premix
Overall (d 0 to 120), no tri-basic copper chloride (TBCC) × standardized ileal digestible lysine (SID Lys) interactions were observed for growth performance, final BW, or caloric efficiency
Summary
Past experiments have suggested that feeding supplemental copper (Cu) in the form of copper sulfate (CuSO4) did not provide growth benefits beyond 135 lb (Hastad et al, 20014). Supplementing finishing diets with 150 ppm of Cu from TBCC increased feed intake and gain, even after the pigs had reached 195 lb. These diets were formulated 0.05% below the estimated standardized ileal digestible (SID) lysine (Lys) level requirement, because previous work in poultry has suggested that when TBCC was added to diets containing marginal levels of Lys, growth performance of broilers was similar to those fed diets adequate in Lys with no additional Cu. A second, more recent study The objectives of this study were (1) to understand how a limited SID Lys diet affects the growth performance of pigs fed Cu from TBCC, and (2) to understand the effects of feeding TBCC during only early finishing or late finishing or for the entire finishing period
