Resumo: 	ABSTRACT This experiment was conducted to evaluate the effect of crude glycerin at differing inclusion levels on performance and carcass characteristics of broilers and litter moisture. 960 broilers of 21-42 days of age were used in a completely randomized design with six crude glycerin inclusion levels (0, 3, 6, 9, 12, 15%), with eight replicates containing 20 broiler chickens per experimental unit. There was a quadratic effect (p&lt;0.05) for weight gain, feed intake and feed:gain ratio from 21 to 42 days of age. Higher levels of crude glycerin in diets increased (40.24%, p&lt;0.05) the litter moisture and reduced (6.04%, p&lt;0.05) the viability of of the birds. There were no effects (p&gt;0.05) on carcass yield, breast, or liver percentages. However, there was an increase (6.17%, p&lt;0.05) in leg yield and a decrease in (p&lt;0,05, 7.05%) the drumstick yield. For the wing yield and abdominal fat, a quadratic effect (p&lt;0.05) was observed. The protein and fat deposition rates, as well as the dry matter content of the carcass, showed a quadratic effect (p&lt;0.05) due to the inclusion levels of crude glycerin. Crude glycerin may be used in broiler diets from 21 to 42 days, at up to 6% ​​without harming the performance of the broilers, the yield and carcass quality, litter moisture, and the viability of broilers. It is recommended that crude glycerin can be fed at 5.63% from 21 to 42 days, while for lower feed conversion it is recommended that the level of 3.72% is used.
