Influence of supplemental manganese and zinc on live performance and carcass quality of broilers

An experiment was conducted to evaluate the influence of varying levels of dietary manganese (Mn) and zinc (Zn) on broiler production. Corn-soybean me al type feeds were supplemented with either 0:0, 60:50, or 180:150 ppm inor ganic Mn:Zn and fed throughout 49 days of production. At 49 days of age, al l birds were subjected to pre-slaughter handling typical of industry practi ce, processed on automated equipment, and manually deboned on stationary co nes. Measurements assessed live performance, carcass quality, and skeletal integrity. Supplemental levels of Mn:Zn did not influence either broiler pe rformance or carcass quality. Skeletal integrity was similarly unaffected.
