Abstract

Over the past decade the poultry industry has made tremendous improvements in production and efficiency that can be attributed to areas of nutrition. Feed additives are one area of nutrition that the poultry industry utilizes to improve performance and efficiency. Experiment 1 investigated the effects of two nutrient densities diets and three enzyme inclusion strategies on 59 d Ross x Ross 708 male broiler performance under a natural disease challenge. These data suggest that when supplementing EIS2 broiler performance and processing characteristics are improved. Additionally, HD also improved broiler performance. The objective of the second experiment was to examine the interactive effects of probiotic and copper inclusion on 42 d Ross x Ross 708 male broiler performance. The resulting data suggests that inclusion of Cu-H at 250 ppm enhances broiler performance while lowering E.coli presence. These data also suggests that BL and Cu-H interact, ultimately reducing the efficacy of BL.
