The nutritional quality and potential use of apple bagasse (BM) in diets for ruminants when silage (microsilos) with two nitrogenous sources (FN) [urea (U), sow (C)], a commercial inoculant (I) was evaluated and Chloris gayana as moisture adherent [80/20 w/w, dry matter (MS)]. The study was conducted in Aguascalientes, Mexico (2014-2016). The treatments: a) BM; b) BM+I; c) BM+U; d) BM+U+I; e) BM+C and f) BM+C+I were analyzed in a completely randomized design (DCA) with factorial arrangement [3 FN (U, C, without FN) × 2 I (with I, without I)]. At 45, the MS of silage was similar between treatments, and lactic and acetic acids increased in greater proportion to propionic and butyric acids. The addition of C (BM+C and BM+C+I) increased the final crude protein (PC) (increments of 8 and 7.44 g 100 g-1 MS) although the pH increased (4.33 and 3.91 vs. 3.41 ±0.03) of the ensilage. Considering the content of PC and fermentation standards, the BM silage with C has the stability and sufficient quality to be used in the feeding of ruminants.
