The study was care out to evaluate the consumption and digestibility of rations with increasing levels of coconut meal by sheep. Eight sheep between six and ten months old installed in metabolism cages were use. The statistical design was a randomized blocks made by SISVAR 3.0 program. To calculate the nutrients consumption, the quantities supplied and the leftovers were weighed to form at the end of the period, a composite sample for laboratory analysis. There was significant difference (P 0.05%) between treatments to digestibility coefficients of DM, OM, energy, HEM, Cellular Content (CC), NFC and total digestible nutrients (TDN). Regarding the coefficient of digestibility of the ether extract (EE), as the by-product was included in the diet, increased the digestibility of this parameter. The digestibility of ADF and NDF decreased as it did the inclusion of the by-product of coconut. Thus, the use of byproduct over 6% of complete feed based on corn and soybeans meal is not recommended.
