Metabolism and Nutrition V: Energy and Enzymes
Feed ingredient costs have been a concern to the U.S. broiler industry. Some integrated operations have reduced apparent metabolizable energy (AMEn ) values to decrease live production costs. Our laboratory has previously determined that 36 to 47 d feed conversion and caloric conversion were optimized with broilers fed diets formulated at 3,200 kcal/ kg. Finishing broilers may respond to diets ...

The urease activity index (UI) is a laboratory test to identify underprocessed soybeans. An experiment was conducted to compare the cor relation coefficient of laboratory test with some biological experiment to evaluation of extruded full fat soybean (EFFSB). One hundred fortyfour day-old male broiler chicks were divided into 12 groups including 3 treatments with 4 replicates and fed 3 diets c...

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...

The utilizable energy content of wheat distillers dried grains with solubles (wheat-DDGS) without or with supplementation of enzyme containing xylanase, amylase and protease (XAP) activities was deter mined for turkeys using linear regression method. A total of 126 BUT 10 male turkeys were fed a nutrient-adequate starter diet from d 1 to 14. On d 14, the birds were assigned to 6 dietary treatm...

higher NDF content than samples from C with samples from A being intermediate (12.0 vs. 8.4 vs. 9.3%; P ≤ 0.001). The Ca (0.43 vs. 0.31 and 0.40%) and K (2.52 vs. 2.11 and 2.21%) content were higher in A samples than in B samples, with C samples being intermediate (P ≤ 0.01). The C samples had higher PDI (22.6 vs. 15.2 vs. 20.1%) and TI content (3.9 vs. 2.8 and 3.4 g/kg) than B samples with A s...
