Metabolism and Nutrition: Nutrition II

A 14-d trial was conducted to determine the effect of dietary protein concentration on performance and health in Pekin ducks during aflatoxicosis . The 4 dietary treatments were arranged in a 2 × 2 factorial with 2 CP concentration (20 and 24% on analyzed basis) with or without 0 .20 mg/kg AFB1 (0 .21 mg/kg analyzed) . Each diet was fed to 6 replicate cages per diet (6 ducks per cage) from 0 to...
