Resumo: | The objective of this paper is to assess the effects of the inclusion of different levels of green propolis extract in the diet of lambs in feedlot on ingestive behavior, nutrients digestibility, physiological parameters and performance. Eight lambs were distributed in double Latin Square with four treatments, corresponding to the inclusion levels (4, 8, 12, 16 mL) of green propolis ethanolic extract (30 g of ground crude propolis was infused in a 100-mL hydroalcoholic solution, 700 mL/L). The diets were composed of Brachiaria brizantha cv. MG5 hay and a commercial concentrate (roughage:concentrate ratio was 50:50) in a dry matter basis. No effect was observed on dry matter (31.2 g/kg of BW), crude protein, ether extract, neutral detergent fiber, non-fibrous carbohydrates and total digestible nutrients content (TDN) intakes. No significant effect was seen on the digestibility coefficients, presenting an average of 65.94% of TDN. The green propolis extract levels do not have a significant effect on behavior or physiologic parameters. Seeking to maximize feeding efficiency, the inclusion of 7.60 mL/day (2.1189 mg of dry matter and 0.1123 mg of flavonoids) of green propolis extract in the diet of lambs in feedlot is recommended.
