Enzymatic characterization of organic phosphorus in animal manure.
Information on the forms of P present in animal manure may improve our ability to manage manure P. In most investigations of manure P composition, only inorganic and total P are determined, and the difference between them is assigned as organic P. In this study, we explored the possibility of identifying and quantifying more specific organic P forms in animal manure with orthophosphate-releasin...
متن کاملPhosphorus composition of manure from swine fed low-phytate grains: evidence for hydrolysis in the animal.
Including low-phytic-acid grains in swine diets can reduce P concentrations in manure, but the influence on manure P composition is relatively unknown. To address this we analyzed manure from swine fed one of four barley (Hordeum vulgare L.) varieties. The barley types consisted of wild-type barley (CDC bold, normal barley diet) and three low-phytic-acid mutant barleys that contained similar am...
متن کاملComparative enzymatic hydrolysis of phytate in various animal feedstuff with two different phytases.
Bacillus amyloliquefaciens DS11 phytase (DS11 phytase) and Aspergillus ficuum phytase (AF phytase) activities were investigated by measuring the release of phosphate from phytate in animal feedstuff such as wheat bran, corn meal, soybean meal and rice flour at pH 5 and 7. In all the tested feedstuff, the enzymatic activity of DS11 phytase was more active at pH 7, but that of AF phytase was more...
متن کاملHuman and Animal Pathogens in Manure
Fecal wastes from domestic animals, wildlife and humans are applied to the soil surface and to varying extents are incorporated into the soil. These fecal wastes can also enter water systems by direct contamination of the water or through seepage or surface runoff. Humans contaminate water sources through poorly processed sewage effluents, malfunctioning septic tanks and seepage from sanitary l...
متن کاملThe influence of enzymatic pre-treatment of corn or soybean meal on their phytate content under different in vitro conditions
BACKGROUND: Phosphorous is one of the expensive nutrients in poultry feed. Therefore, improving the bioavailability of this nutrient in feed ingredients could be effective for lowering the cost of feed. OBJECTIVE: This study was performed to evaluate the effect of pre-treatment of feed ingredients by commercial enzymes and different levels of pH on releasing of phosphorus from phytate under in ...
