| Abstract: | The objective of this study was to evaluate the correlation among total phosphorus,phytate phosphorus and true availability of phosphorus in adult Cherry Valley ducks,and the regression models of true available phosphorus in common feedstuffs were established,which could provide scientific evidence for an exact feed formula in ducks.Common feedstuffs for ducks were collected from the country,and 30 feedstuffs were selected as the representative samples according to the chemical composition and variation.The... |
