Weanling pigs (total of 560) were used in two experiments to determine the effects of poultry meal in nursery diets on pig performance. In Exp. 1,210 barrows and gilts (initially 7.4 kg and 21 +/- 2 d of age) were fed one of five diets, which included a control diet with no specialty protein products or (as-fed basis) the control with 2.5 or 5.0% fish meal, or 2.9 or 5.9% poultry meal (11.8% as...
The purpose of this study was to determine the feasibility of estimating the total and phytate P content of common poultry feed ingredients by near-infrared reflectance spectroscopy (NIRS). Samples of 8 plant-origin feedstuffs were collected from poultry producers in the USA and Canada during the summer of 2009: corn (133), soybean meal (114), corn distillers dried grains with solubles (DDGS; 8...

The proximate composition, pepsin digestibility, gross energy and macro mineral contents of 12 composite samples of poultry offal meal produced in Sri Lanka were analyzed. The average dry matter, ash, crude protein, crude fiber, ether extract, in vitro pepsin digestibility and gross energy of poultry offal meal were 92.3, 6.9, 48.9, 2.1, 32.4, 83.8% and 23.6 MJ kg, respectively. The average Ca,...
Two experiments were conducted to determine the concentration of DE and ME and the standardized ileal digestibility (SID) of AA in chicken meal, poultry byproduct meal, hydrolyzed porcine intestines, a spent hen–soybean meal (SBM) mixture, and conventional SBM fed to weanling pigs. In Exp. 1, 48 barrows (initial BW: 14.6 ± 2.2 kg) were placed in metabolism cages and allotted to 6 diets with 8 r...
In situ, digestion, and growth studies were conducted to evaluate four meat and bone meals and six poultry by-product meals as sources of escape protein and to predict the first-limiting amino acid for growing calves. Escape protein values, determined by 12-h in situ incubation, ranged from 41.7 to 51.0% of CP for meat and bone meals; poultry by-product meals ranged from 32.0 to 39.8%. True pro...

Organoarsenical drugs are widely used in the production of broiler chickens in the United States. Feathers from these chickens are processed into a meal product that is used as an animal feed additive and as an organic fertilizer. Research conducted to date suggests that arsenical drugs, specifically roxarsone, used in poultry production result in the accumulation of arsenic in the keratinous m...
