Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...

Corn gluten meal (CGM) is a major coproduct of corn wet milling; it has value because of high protein. However, variation in composition and high P content reduce market value. Data that characterize gluten streams would be helpful in identifying key processing steps that could be modified to improve the quality of CGM and increase processing efficiency. Few data are published in the literature...

Objective: The aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (CGM) and its effect on growth performance of broiler chicks. Methods: Chemical composition and nitrogen corrected true metabolizable energy of CGM was determined by standard and precision-fed cockerel assay methods.  For evaluating of protein quality, 90 male broiler chicks in a com...

Sixty multiprious Holstein cows were fed treatment diets from 11 to 40 d postpartum with corn silage as the forage. Treatment diets each contained a different supplemental protein: 1) solvent soybean meal; 2) extruded soy product; 3) combination of corn gluten meal and distillers dried grains with solubles; and 4) a combination of protein sources from diets 2 and 3. Covariate adjusted means for...

an experiment was conducted to evaluate the extracted (es) and mechanical (ms) soybean meals two levels 25% and 35% in broiler chicken feeding. three hundred and fifty two one-day-old unsexed lohman chickens were placed in four treatments by 4 replicates and 22 chickens in each in a 2×2 factorial arrangement. feed intake was increased significantly in starter period by es in comparison with ms....

An amino acid deletion assay, a protein efficiency ratio (PER) assay, and a slope-ratio growth assay were used to establish the limiting order of AA, and to determine the effects of microbial phytase on protein utilization in corn gluten meal (CGM) fed to chicks during the period of 8 to 21 d posthatching. In Assay 1, a 12% CP CGM diet was fortified with AA to fulfill the digestible AA ideal pr...

Twenty-five (10 ruminally cannulated) Holstein cows averaging 82 +/- 34 d in milk were assigned to 5 x 5 Latin squares (21-d periods) and fed diets supplemented with one of four different proteins to assess effects on production, ruminal metabolism, omasal flow of N fractions, and degradation rates of protein supplements. Total mixed diets contained (dry matter basis) 44% corn silage, 22% alfal...

Three experiments were conducted to evaluate the efficacy of replacing corn and dried whey with corn gluten meal (CGM) and lactose, and to evaluate two sources of edible-grade dried whey that elicited different postweaning pig growth performances. In Exp. 1, two corn-soybean meal (C-SBM) diets without or with 20% dried whey (C-SBM-DW) were formulated to contain 1.15% lysine. A third diet replac...

Eight dual-flow continuous-culture fermenters were used in four replicated periods to compare the effects of diet and microbial marker on estimates of N metabolism in continuous culture of ruminal microorganisms. A basal diet was supplemented with urea and tryptone, soybean meal (SBM), lignosulfonate-treated SBM, corn gluten meal, blood meal (BM), hydrolyzed feather meal, fish meal (FM), or mea...

Partial or total replacement of fish meal by a mixture of plant protein (PP) sources (corn gluten, wheat gluten, extruded peas, rapeseed meal and sweet white lupin) balanced with indispensable amino acids was examined in juvenile gilthead sea bream over the course of a 6-month growth trial. A diet with fish meal (FM) as the sole protein source was compared to diets with 50%, 75% and 100% of rep...
