摘要: Phosphorus is an essential mineral for growing poultry, and the consequences of a failure to provide adequate quantities this nutrient are physiologically economically disastrous. Therefore, nutritionists margin safety in their diets. However, because concerns regarding potential contribution P poultry excreta on eutrophication surface waters, increasing pressure being placed limit amount excess diets thus reduce fecal output. In order significantly while maintaining economic productivity, nutritionist must establish maintain integrated program activities, including effective quality control incoming animal protein feeds, selection supplements highest biological value, use phytase enzymes, judicious dietary levels. Potential benefits newer isomers vitamin D commercial development grains with high levels nonphytate offer promise future. Whatever measures taken increase availability phytate-bound portions diet, commensurate reductions overall content be made.
