Table 4. Formula that calculate lysine content of soybean meal and corn from crude protein content

Ingredient	Linear regression equation Lysine/% CP content1)	Standard error	Correlation coefficient
Dehulled soybean meal (N = 175)	Y = 0.264 + 0.60(X)	0.175	0.57
Corn (N = 95)	Y = 0.049 + 0.026(X)	0.018	0.66

Y = A + BX: where Y = % amino acid, A = intercept, B = slope, X = % CP content.
