The objective of this study was to evaluate the effect of different levels of crude glycerine in the rations on the performance of growing and finishing pigs. 60 F1 pigs (30 males and 30 females), deriving from the cross between Naima females and commercial line P76males, with an initial weight of 18.46 ± 1.38 kg, distributed in a completely randomized design, with 4 treatments and 5 replications, with 3 animals per experimental unit. The rations were formulated on the basis of corn and soybean meal, with the inclusion of 0, 5, 10 and 15% of crude glycerine. The performance characteristics evaluated were: weight gain, feed intake and feed conversion. There was no influence (p>0.05) found in the inclusion of crude glycerine in the rations on the performance characteristics evaluated in the phases of growth and termination. The inclusion of up to 15% of crude glycerine in the diets of growing and finishing pigs is recommended, without harmful effects for productive performance.
