Current experiment evaluated the inclusion effect of crude glycerin levels in the diet on the feeding behavior of confined dairy cows. Fifteen crossbred Holsteinx Zebu cows were used, divided into three 5 x 5 Latin squares, with treatments: control (no addition of glycerin) and inclusion of 50, 100, 150 and 200 gcrude glycerin per kg of dry matter (DM) in the diet. The animals were subjected to five visual assessments of feeding behavior for 24 hours in each period. Linear increase on feeding time and rumination and on decrease of idle time with the inclusion of crude glycerin levels (p 0.05). Crude glycerin did not drastically affect the feeding behavior of dairy cows.
