The objective of this study was to evaluate the effect of inclusion of pineapple (Ananas comosus L.), banana (Musa sp.), mango (Mangifera indica), and passion fruit (Passiflora sp.) residue in replacement of 75% corn silage in diets for confined sheep on nitrogen balance. Twenty 5 Santa Ines crossbred sheep male, rumen fistulated, castrated were used with approximate initial age of 24 mo, and initial body weight of 45.4 ± 6.1 kg. Experiment was conducted in Latin square design (5 ×5), with 5 treatments, 5 animals, and 5 experimental periods of 13 d each. The diets were formulated to contain approximately 72% total digestive nitrogen, and 14.7% crude protein. The forage: concentrate diet was 40:60 (% dry matter), and the forage in the control diet was composed of 100% corn silage. We carried out daily records of food provided and the remains of these, to ensure 10% of leftovers. To estimate the fecal nitrogen, total feces were collected during 96 h, using bag collectors. The urinary nitrogen were estimated collecting urine during 72 h. Nitrogen balance was measured by subtracting the total nitrogen intake and total nitrogen excreted in feces, and urine. The results were analyzed by ANOVA, and Dunnett test at 5% probability, using the Statistical Analysis System. There was no difference (P > 0.05) among fruit residue, and corn silage for nitrogen values (intake, fecal, urinary, absorbed, and retained). N itrogen balance was positive, and presented a mean value of 15.73 g day of nitrogen retained in animal body, representing 51.27% ingested nitrogen, indicating better utilization of nitrogen by sheep. The amount of nitrogen intake averaged 30.69 g day⁻¹, and fecal and urinary losses represented, respectively, 28.87 and 19.87% ingested nitrogen. We conclude that the use fruit residue to replace 75% corn silage DM is viable and do not interfere the nitrogen balance and nitrogen retention.
