مستخلص: The objective of the current study was to evaluate the effects of soybean oil inclusion in diets on feeding behaviour, digestibility, performance, and blood metabolites of feedlot lambs. Forty non-castrated Santa Inês lambs with a mean age of 5 months and initial body weight of 34.88 ± 3.19 kg were used in a 40-day feeding trial. The lambs were distributed in five experimental diets with the inclusion of increasing soybean oil (SO) levels: 0, 30, 60, 90, and 120 g/kg DM. The SO inclusion promoted a linear reduction in DM intake ( p < 0.001), crude protein (CP, p < 0.001), non-fibrous carbohydrates (NFC, p < 0.001), and total digestible nutrients (TDN, p = 0.004). There was an increasing quadratic effect on the intake of ether extract (EE; p = 0.002) and decreasing for neutral detergent fiber ( p = 0.005). The soybean oil inclusion promoted the greater apparent digestibility of CP ( p = 0.016), EE ( p = 0.005), NDFom ( p < 0.001), and TDN ( p < 0.001); on the other hand, the apparent digestibility of NFC ( p = 0.005) was decreased. The average daily gain decreased ( p < 0.001) with SO inclusion. The SO inclusion increased feeding time ( p = 0.004), reduced the efficiency of DM rumination ( p = 0.001), and reduced the concentration of blood N-ureic ( p < 0.001). Considering the productive parameters, SO can be included in diets and it is recommended that we include SO of up to 41 g/kg DM in diets for fattening lambs as the ideal maximum level. The strategy implemented to adapt lambs to increasing levels of high-fat diet mitigated the detrimental effects of lipids on the rumen, with high-density energy intake being the constraining factor on performance.
