Evaluation of near-infrared reflectance spectroscopy (NIRS) techniques for total and phytate phosphorus of common poultry feed ingredients.
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...
متن کاملP122 Effects of phytase supplementation on ileal digestibility of phytate phosphorus and total phosphorus of feed ingredients for broiler chickens
This study aimed to evaluate the effect of a heat stable phytase derived from Citrobacter braakii on true digestibility of P and on phytate dephosphorylation at the terminal ileum segment in broiler chickens. Four semi-synthetic diets, each containing either wheat, maize, soybean meal or rapeseed meal as the only source of phosphorus and calcium were supplemented with microbial phytase at 1000 ...
متن کاملPhytase transgenic corn in nutrition of laying hens: residual phytase activity and phytate phosphorus content in the gastrointestinal tract.
The residual activities of transgenic corn-derived and 2 commercial microbial phytases (PA and PB) along the gastrointestinal tract (GIT) of laying hens were compared to evaluate their relative resistance to hydrolysis in the GIT when added to P-deficient diets. The treatments consisted of a negative control (NC) diet containing 0.10 nonphytate P and an NC diet supplemented with transgenic corn...
متن کاملApproaches and challenges to engineering seed phytate and total phosphorus
About 75% of seed total phosphorus (P) is found in a single compound, phytic acid (myo-inositol1,2,3,4,5,6-hexakisphosphate or InsP6). Phytic acid is not efficiently utilized by monogastric animals (poultry, swine, fish), which creates phosphorus management and environmental impact problems in animal production. Phytic acid also functions as an antinutrient when consumed in human and animal die...
متن کاملMeasurement of inorganic phosphorus in soybeans with near-infrared spectroscopy.
This study explored the feasibility of near-infrared (NIR) quantitative and qualitative models for soybean inorganic phosphorus (Pi), which is complementary to phytic acid, a component of nutritional and environmental importance. Spectra, consisting of diffuse reflectance (1100-2500 nm) of ground meal and single-bean transmittance (600-1900 nm) of whole seed, were collected on 191 recombinant i...
