Figure 2–The relationship of cholecalciferol content in yolk and dietary cholecalciferol level in the feed of diet 1 to 5. The data of week 3 to 40 from diet 1 to 4 were fitted in a generalized linear model with gamma distribution and identity link. The likelihood-ratio test for the lack of fit gave P = 0.985 (n = 4). The presented linear equation applies to diet 1 to
4, not to diet 5.
