Resumo: | ABSTRACT: The aim of this study was to measure the nitrogen (N) balance of pigs fed with lysine-limiting diets containing practical levels of wheat bran (WB) or soybean hulls (SH). Twelve pigs with average weights of 57.36±2.01 and 72.68±3.24 kg were used in trials 1 and 2, respectively. In trial 1, treatments were CT1 - control diet and WB - diet with inclusion of 15% WB. In trial 2, CT2 - control diet and SH - diet with inclusion of 6% SH. Fibrous diets increased (P<0.05) the fecal N in 63.54 and 60.55% in relation to CT1 and CT2, respectively. The urinary N was higher (P<0.05) in pigs receiving the WB diet, but was not influenced in the trial with SH. The N retention (NRET) was higher (P>0.05) in pigs ingesting the WB diet; although, when the proportion of NRET was expressed relative to N ingested (NING) there was no difference (P>0.05) between treatments. Inclusion of SH did not affect (P>0.05) the NRET when the result was expressed in absolute or proportional terms. In conclusion, inclusion of practical levels of WB and SH does not significantly affect the metabolic costs involved with nitrogen metabolism. However, only WB was able to contribute to the N balance of pigs, while the relative amount of N added by SH was fully recovered in feces. |
