Relationship between body ash weight and body protein weight at the time of slaughter weights in growing and finishing pigs; individual data points (n 211) represent mean values for each considered dietary treatment reported in twenty-five studies (see online Supplementary material for a list of included studies). The data were expressed on the natural logarithmic (ln) scale, under the following three ad libitum feeding schedules: (1) pigs were given protein-deficient feeds; (2) pigs were given nutritionally balanced feeds; (3) pigs were given phosphorus-deficient feeds. Data: Inline graphic, protein-deficient feed; Inline graphic, balanced feed; Inline graphic, phosphorus-deficient feed.
