Fig. 2. — Body weight (BW)-scaled average daily feed intake (ADFI/BW; kg/kg per d) against feed standardised total tract digestible (STTD) phosphorus content (g/kg): individual data points (n 97) represent mean values for each considered dietary treatment reported in fifteen studies (see online Supplementary material for a list of included studies). The dotted line represents the overall predicted effect of feed STTD phosphorus content on the scaled ADFI. Probability (P) and coefficient of determination (R²) values are given for the overall fit and for fit within the included experiments. * P < 0·05; ** P < 0·01; *** P < 0·001.
