Effects of Direct-Fed Microbial Products, Butyrate, and Botanicals on Performance and Health of Broilers Raised on Used Pine Shaving Litter
… and NC + 0.40% DFM2). Experimental diets were fed to broilers over a 42-day period. Body weight gain (BWG) was depressed from d 0-28 and d 0-42 with supplementation of 0.10% DFM1 and 0.05% DFM2 compared to NC fed birds (P ≤ 0.05), with no differences among the remaining treatments and the NC …

Effects of Nutritional Manipulation on Poultry under Normal and Stressful Conditions
… dissertation was to investigate the effects of a direct fed microbial (DFM) on broilers exposed to a cyclic heat stress in 2 consecutive experiments. In this experiment, the heat stress treatment reduced body weight gain and lean tissue accretion from 0 to 35 d in both experiments. In Experiment …
