Data are given as tank means ± s.d. in μmol kg^-1 wet muscle mass (N=3).

Sums of DAA (dispensable amino acids), IDAA (indispensable amino acids) and total FAA (free amino acids) (mmol kg^-1 wet mass) represent the sum of FAA given here and in Fig. 2.

‡

Orn/Pro and Hyp/Pro data were calculated from values given in Fig. 2.

Superscript letters represent significant effects of dietary treatment;data within an experiment not sharing a superscript letter are significantly different at P<0.05.
