1 PC = Positive control; NC = Negative control, SP = Soy protein concentrate, SB = Soybean meal, XLA = X-low-protein + amino acids. 2 Standardized ileal digestible = SID: The content of SID CP and amino acids were calculated based on analysed total values of the six dietary treatments and on SID digestibility coefficients of the feed ingredients from Danish Agro (Sjölund, Denmark).
