A basal diet (adaptation diet) which contained
MLM as the sole source of dietary
protein and DL- methionine was added at
0.12% in the basal diet. This diet was formulated
to contain 16 % CP, 2850 kcal ME/kg.
Assay diet was the same with basal diet except
for the elimination of synthetic methionine.
A protein-free diet was also formulated
specifically to allow the determination of
endogenous flows of amino acids. All diets
were fed in mash form. Chromic oxide was
included in all diets as an indigestible marker.
The composition of the basal, as say and
protein-free diet and its amino acid contents
are shown in Table 1 and Table 2 respectively
