Conteúdo: 	The objective of this trial was to evaluate the effect of crude glycerin (CG) inclusion on feeding behavior of feedlot lambs. Forty Santa Ines intact males lambs were assigned in a completely randomized block. The diets presented 18% of roughage and 82% of concentrate. Five treatments were used: 0%
CG, 7.5% CG, 15% CG, 22.5% CG and 30% inclusion of CG on dry matter basis, whereas, the diet with 30% of CG promoted a total replacement of corn. The diets were offered twice daily at 0700 and 1600 h with 50% of total in each meal. Feeding behavior was performed during 48 h by 2 trained observers that made visual observations every 5 min of feeding, drinking, ruminating, resting and other activities. Further, the ruminating efficiency was determined. The means of 2 d were calculated expressed in 24 h. The data were analyzed using the MIXED procedure of SAS and the treatments were compared using orthogonal contrasts (linear and quadratic) considering 5% of significance level. There was no difference treatments among the variables measured (P > 0.05). The exception was drinking activity that showed a quadratic response (P = 0.04). On average, the animals presented 16.6 min drinking, 234.4 min eating, 428 min ruminating, 535 min resting and 226.8 in other activities. The ruminating efficiency was 325 (min of ruminating/kg DMI). In conclusion, crude glycerin in feedlot lambs influences only time spent drinking.
