Bioactive Compounds of Barbatimão (Stryphnodendron sp.) as Dietary Additive in Lamb Diets. Agriculture 2023, 13, 664.http://hdl.handle.net/10919/114200This study aimed to evaluate barbatimão bark extracts as a feed additive and substitute for lasalocid sodium (LAS) for feedlot lambs. Lambs were distributed into three treatments: LAS (0.018 g of lasalocid sodium), DBB (1.500 g of dried and milled barbatimão bark), and BHE (0.300 g of barbatimão hydroalcoholic extract). There was no effect (<i>p</i> = 0.32) of the inclusion of DBB and BHE extracts on the average daily gain. Inclusion of BHE in lamb diets reduced (<i>p</i> &lt; 0.05) the fatness score compared to LAS, which was similar to DBB. The BHE decreased the yellowness intensity and hue angle (<i>p</i> &lt; 0.05) of meat compared to the LAS. Animals that consumed DBB and BHE had a reduced (<i>p</i> = 0.04) total cholesterol level. Thus, the use of barbatimão bark extracts can replace lasalocid sodium in the diet of feedlot lambs, with no detrimental effects on performance or metabolic parameters.application/pdfenCreative Commons Attribution 4.0 Internationalruminantstanninsbioactive compoundssaponinsfeed additivesArticle - Refereed2023-03-28https://doi.org/10.3390/agriculture13030664
