Thirty-two male Santa Inês sheep with an average body weight of 20.09 ± 2.0 kg were distributed in a completely randomized block design with four treatments (0, 33.3, 66.6, and 100 % of substitution of corn silage with buffel grass silage) and eight animals per treatment. Dry matter intake, apparent nutrient digestibility, water balance, nitrogen balance, and productive performance of animals were evaluated. The different levels of substitution of corn silage by buffel grass silage promoted a linear decrease in the consumption of ether extract (P=0.001) and non-fibrous carbohydrate (P&lt0.001), apparent digestibility of non-fibrous carbohydrate (P=0.019), water intake via food (P&lt0.001), total water intake (P=0.008), water excretion via urine (P=0.004), total water excretion (P=0.001), among which the highest values were observed in animals fed 100% corn silage. Water excretion via feces (P=0.017) and nitrogen balance (P=0.047) showed a quadratic function, increasing as substitution with buffel grass silage increased from 0 to 33.3 %. No significant differences (P&gt0.05) were observed in sheep productive performance, with an average daily weight gain of 140.16 g/d. The replacement of 66.6 % of CS for BGS provides satisfactory results for dry matter and nutrients intake, and water intake, with weight gain of up to 155 g/d for Santa Inês crossbred sheep in Brazilian semi-arid.  aAnimal nutrition  aSheep  aCapim Buffel  aOvino  aPastagem  aSilagem  aOvinos confinados  aOvinos mestiços  aRaça Santa Inês  aSemiarido  aSilagem de milho1 aARAUJO, G.
