Resumo: 	Dry fecal matter production was estimated from neutral detergent indicators on indigestible fiber, indigestible acid detergent fiber, indigestible dry matter, incubated for 144 hours and 288 hours, as well as chromium oxide (Cr2O3) and enriched and purified isolated lignin (LIPE®) in two sampling schemes (3 and 5 days) on buffaloes. Sample consisted of five castrated animals with average weight of 300 ± 0.6 kg fed on elephant grass cv Cameroon (Pennisetum purpureum). Experimental design consisted of randomized blocks in subdivided plots. Production of dry fecal matter was overestimated when using Cr2O3, indigestible acid detergent fiber 144 hours, indigestible neutral detergent fiber 144 hours, indigestible neutral detergent fiber 288 hours and indigestible dry matter 144 hours, while indigestible acid detergent fiber 288 hours, indigestible dry matter 288 hours and LIPE® did not differ from total collection. The same result was observed for apparent digestibility of nutrients. There was no difference in dry fecal matter production and digestibility between both collection periods of 3 and 5 days, demonstrating that a collection period of three days can be used to estimate dry fecal matter production in buffaloes. A three-day period of sample collection, in order to estimate dry fecal matter production and apparent digestibility coefficients, is therefore recommended. The use of LIPE®, fibers in indigestible acid detergent and indigestible dry matter as indicators, both latter incubated for 288 hours, result in accurate estimates of dry fecal matter production in confined buffaloes, fed on a forage based diet.
