ABSTRACT
The objective of this study was to evaluate the nitrogen metabolism of lambs fed diets containing peach palm meal substituting maize (0, 10, 40, 60, and 85 % DM). Thirty Santa Inês uncastrated lambs with an average initial body weight of 21.6 ± 0.87 kg were distributed in a completely randomized design with five diets and six replicates. The nitrogen (N) intake (g/day, %BW) and the fecal N decreased linearly as the peach palm meal was added to the concentrate. The urinary N, however, responded quadratically, with maxima at the level of 29.97 and 40.44 % of substitution of maize for peach palm meal when expressed in g/day and %BW, respectively. The substitution of maize for peach palm meal reduced the retention of nitrogen and the microbial protein synthesis in the lambs.
