摘要

Using lipids can correct energy deficiencies in pasture, boost weight gain in ruminants, and enhance profitability in farming activities. The objective of this study was to evaluate the energy losses in feedlot steers fed diets based on corn silage, with or without the addition of lipids in the form of soybean oil or ground soybean seeds. Eight steers were randomly assigned to two balanced 4 × 4 Latin squares. The experimental treatments were as follows: corn silage; corn silage and concentrate feed without lipid addition; corn silage and concentrate feed with 5% lipid (soybean oil) addition; corn silage and concentrate feed with 5% lipid (ground soybean seeds) addition. The results showed that steers fed only corn silage had (p < 0.001) lower dry matter intake (DMI) compared to other treatments. Gross energy intake and gross energy in feces mirrored DMI trends (p < 0.05). Diets with concentrate supplements resulted in higher digestible energy intake (p < 0.05) and increased gross energy in urine. Notably, adding lipids decreased (p < 0.05) methane energy losses, although the processing method did not (p > 0.05) impact these outcomes. In conclusion, adding lipids to the diet reduced energy losses through methane emissions, increasing steers’ energy efficiency. Therefore, the inclusion of lipids reduced enteric methane production in steers. Additionally, the method of lipid processing (soybean oil or ground soybean seeds) did not affect energy partitioning.

使用脂质可以纠正牧场中的能源缺陷，提高反刍动物的体重增加并提高农业活动的盈利能力。这项研究的目的是评估基于玉米青贮饲料的饲养场饮食中的能量损失，或者以大豆油或地面大豆种子形式添加脂质。将八个牛随机分配到两个平衡的4×4拉丁正方形。实验处理如下：玉米青贮饲料；玉米青贮饲料和浓缩饲料，而无需添加脂质；添加5％脂质（大豆油）的玉米青贮饲料和浓缩饲料；玉米青贮饲料和浓缩物加入5％脂质（地面大豆种子）添加。结果表明，与其他治疗相比，饲喂玉米青贮饲料的转向仅具有较低的干物质摄入量（DMI）（DMI）。粪便中的总能量摄入和总能量反映了DMI趋势（p <0.05）。浓缩补充剂的饮食会导致较高的消化能量摄入量（P <0.05），并增加了尿液中的总能量。值得注意的是，添加脂质降低（p <0.05）甲烷能损失，尽管加工方法没有影响这些结果。总之，添加脂质在饮食中添加脂质，通过甲烷排放减少了能量损失，从而提高了转向的能量效率。因此，包含脂质会减少转培训。此外，脂质加工方法（大豆油或豆种子）不会影响能量分配。
