Fig. 2From: Determination of the dietary lysine requirement by measuring plasma free lysine concentrations in rainbow trout Oncorhynchus mykiss after dorsal aorta cannulationBroken line analysis of post-absorptive plasma lysine concentrations (nmol/mL) in rainbow trout fed graded levels of dietary lysine. Values of the X-axis are the lysine levels in the experimental diets. Values are means ± SD of 5 replicates. Y = 75.25× + 98.22, Y’ = 263.5, R 2 = 0.9813Back to article page
