RESUMO
The objective of this study was to evaluate the effects of the inclusion of different levels of licuri cake on the consumption of dry matter and nutrients and ingestive behavior of feedlot crossbred steers. Forty-four crossbred steers with an average age of 24 months and a mean live weight of 358.19 ± 41.57 kg were used in the study. The animals were aleatorically distributed in a completely randomized design made up of four treatments, with 11 animals used per treatment: the control treatment (without the inclusion of licuri cake in the diet) and treatment with the inclusion levels of 8.5, 17, and 25.5% of licuri cake, respectively, in the total dry matter of the diet. The inclusion of licuri cake influenced the intake of dry matter, crude protein, ether extract, neutral detergent fiber corrected for ash and protein, and non-fibrous carbohydrates corrected for ash and protein, each of them showing quadratic behavior. There was an effect of the tested diets on the time spent on food intake and number of idle periods, which presented a quadratic effect, with maximum and minimum values obtained for the inclusion levels of the licuri cake of 16.92% and 11.00%, respectively. There was no effect of the tested diets on the time spent on rumination and idleness. The feed efficiency of the dry matter, the duration of the feeding period, and the duration of the idleness period were influenced by the inclusion of the licuri tart in the diet, presenting a linear decreasing effect. There was an increasing linear effect for the number of feeding periods and the duration of rumination periods. Given the results obtained, it can be concluded that the licuri cake changes the consumption and behavioral parameters of feedlot steers, being recommended its use in up to 8.5% of inclusion in the total dry matter of the diet.
