A total of 523 sampes of the substrates and fluid rumen was tested using urea, NH4H2PO41 (NH4)2So4, NH4CI, NH40H, cotton seed meal (CSM) and soil bean meal (SBM), at doses of 1.0 and 1.5% of added N, supplement with starch at 15%, glucose at 10% or sucrose at 10%. Increase in digestibility (P < 0.05) were observed with energy source plus urea at 1.0 and 1.5%. Digestibility increased by 8.7; 7.2 and 9.4 percentage units (p.u) for milo stalk; 4.0; 4.2 and 6.1 (p.u) for bagasse and 2.3; 4.4 and 4.5 (p.u) for wheat straw with glucose, sucrose or starch, respectively. Differences (P < 0.05) were found with NH4NO3, NH4H2PO41 (NH4)2SO4 at 1.0 or 1.5% with glucose, sucrose or starch, and the ammonium chloride had an effect (P < 0.05), equivalent to 8.5% for milo stalk, 5% for bagasse and 1% for wheat straw plus glucose, sucrose or starch. Ammonium hydroxide reduced digestibility by 5.9% at 1% level. However, it showed an increment of 4.8% when sucrose was added. Reduction of 10.8% as an average was registered at 1.5% level with the three energy sources. On the other hand, increased (P < 0.05) on digestibility was observed using N from CSM or SBM. However, a better response (P <0.05) was found with N from SBM plus energy sources with milo stalk, bagasse or wheat straw supplemented with N at 1.0 or 1.5% levels. Se realizó un estudio sobre digestión in vitro para evaluar el efecto de ocho fuentes de nitrógeno (N) y Ia interacción con tres fuentes de energía sobre Ia digestibilidad del tallo de sorgo, bagazo de caña de azúcar y paja de trigo. En total se evaluaron 523 muestras de los diferentes substratos, adicionados con liquido ruminal y urea, NH4NO3, NH4H2PO4, (NH4)2SO4, NH4CI, NH40H y torta de algodón (TA) con dosis de 1.0 y 1.5% de N, más suplemento de almidón al 15%, glucosa al 10% y sucrosa al 10%. Aumentos significativos en digestibilidad (P < 0.05) en Ia digestibilidad, equivalente al 8.5% para el tallo de sorgo, 5% para el bagazo y 1% para Ia paja de trigo más glucosa, sucrosa y almidón. El hidróxido de amonio redujo Ia digestibilidad en 5.9% a nivel del 1%. Sin embargo, el mismo producto mostró un aumento de 4.8% al usar sucrosa. Una reducción promedia de 1 0.8% en digestibilidad se registró a niveles del 1.5% con las tres fuentes de energía usadas en el estudio. De otro lado, un aumento significativo (P <0.05) en digestibilidad se notó usando N de TA y torta de soya (TS). Sin embargo, una mejor respuesta se obtuvo con el N de Ia TS al 1.0 y 1.5%, más las fuentes energéticas con tallo de sorgo, bagazo de caña o paja de trigo.
