In order to evaluate the effect of ammonization in the production residue of Brachiaria brizantha seeds in the performance and in vivo biometric measurements of sheep, 19 Santa Inês lambs (females and non-castrated males) were used, with initial weight of 15kg, confined in individual cages until reaching 28kg. Animals were arranged into two groups, receiving isoenergetic and isoproteic diets with 40:60 volumous:concentrate ratio, being diet 1 (D1) made up with non-treated volumous with urea + addiction of urea in concentrate and diet 2 (D2) with treated volumous with addiction of 2% urea in MS + concentrate without urea. Dry matter consumption was similar between diets and sexes (0.85 kg/day, 3.28%/BW e 73.15 g/kg0,75/day); however, the remaining performance parameters were affected by the different sexes of animals. There was not interaction between diet and sex in biometric measurements; however, body length was higher for females (66.50 cm) compared to males (61.12 cm). We conclude that the effect of ammonization in diet volumous did not affect performance and biometric measurements of sheep terminated in confinement, being that some changes occurred due to the different sexes of the animals.KEY WORDS: Chemical treatment, nutritional value, sheep, urea, volumous.
