Estimation of standardized phosphorus retention for corn, …
The determined value of SPR of the C-SBM diet was lower (P<0.001) than the predicted summation of SPR from corn and SBM (39.7 vs. 46.0%), which might be due to the effect of higher total P intake. The results from the current study demonstrated that the P-free diet could be used for measuring basal EPL in broilers and then estimating the SPR ...
