This experiment was conducted to evaluate effects of different sources of natural pigments on yolk color and laying hen performance. A completely randomized design with six treatments and six replicates was used.The six experimental treatments were: a control diet containing yellow corn grain, a reference diet containing wheat and barley grain instead of corn; a red pepper diet composed of refe...

the effects of different sources of carbon, nitrogen and some of trace elements on cultivation of bacillus thuringiensis h14 were studied. glucose, glycerol, sodium acetate, (nh4)2so4, corn steep liquor, yeast extract, hydrolyzed casein, ca2+, mg2+ and mn2+ were the main parameters evaluated by plackett-burman statistical method. all elements have insignificant effect on germination while spore...

Paddy rice is rarely used as a feed because of its high fiber content. In this study, two experiments were conducted to study the effects of supplementing an enzyme complex consisting of xylanase, beta-glucanase and cellulase, to paddy-based diets on the performance and nutrient digestibility in meat-type ducks. In the both experiments, meat-type ducks (Cherry Valley) were randomly assigned to ...

The feeding value of extruded and nonextruded wheat and corn distillers dried grains with solubles (DDGS) for broilers was evaluated in 2 experiments. In experiment 1, male broilers (n=360) housed in battery cages were fed assay diets that included either 15 or 30% wheat or corn DDGS (extruded or not) in relation to a basal diet from d 21 to 28. Birds were killed on d 28 and ileal digesta was c...

This experiment was conducted to study the effect of Aflatoxins (AF) on broiler performance, organ weight, plasma characteristics, protein digestibility, and metabolizable energy of the diets. Dietary treatments were: 1) control diet based on corn and soybean meal; 2, 3 and 4) control diet plus 1 mg kg-1 AF, 1 mg kg-1 AF and 0.25% mycosorb, and 0.25% Mycosorb, respectively. The results in the A...

Three experiments were conducted to determine the efficacy of limit-feeding corn-based diets as an alternative to hay for beef cows in gestation and early lactation. Seventy or 71 mature, pregnant Simmental crossbred cows (average weight = 589 +/- 10 kg) were used in each trial. Each of 29 or 30 cows was fed approximately 5 kg of whole shelled corn, 1.2 kg of a pelletted supplement, and 1 kg of...

Two experiments were conducted to determine the standardized total tract digestibility (STTD) of P and the concentration of DE and ME in corn, hominy feed, bakery meal, distillers dried grains with solubles (DDGS), corn gluten meal, corn gluten feed, and corn germ meal fed to growing pigs. In Exp. 1, 84 barrows (initial BW: 13.7±2.3 kg) were placed in metabolism cages and allotted to 14 diets w...
