-derived feeds have been recognized for their economic and environmental benefits in ruminant nutrition. However, their utilization is constrained by the presence of glucosinolates and sulfur-containing compounds that exhibit both beneficial and adverse effects. This meta-analysis included 36 studies that evaluated the impact of glucosinolate intake on ruminant performance, nutrient digestibility, milk composition, and methane emissions. This analysis, conducted in accordance with PRISMA guidelines, revealed that glucosinolate supplementation resulted in a quadratic increase in milk urea nitrogen concentration ( = 0.017). Additionally, significant interactions between glucosinolate level and source influenced crude protein digestibility ( = 0.026). Milk composition parameters, including 4% fat-corrected milk, energy-corrected milk, milk protein, and lactose proportions, were significantly affected ( < 0.05). Furthermore, methane emissions (g/kg DMI) decreased quadratically with increasing glucosinolate intake ( = 0.003), with additional interactions observed between dietary treatments and animal species ( = 0.029). Propionate and isobutyrate concentrations increased in a quadratic and linear manner, respectively ( < 0.05). These findings suggest that glucosinolate-containing feed can enhance nutrient utilization and mitigate methane emissions in ruminants. However, the magnitude of these effects is dependent on the glucosinolate dosage, source, animal species, and dietary composition, necessitating further research to optimize their use in ruminant nutrition.
衍生饲料因其在反刍动物营养中的经济和环境效益而得到认可。然而，它们的利用受到硫代葡萄糖苷和含硫化合物的限制，这些化合物既具有有益作用，也具有不利影响。这项荟萃分析纳入了36项研究，评估了硫代葡萄糖苷摄入量对反刍动物生产性能、养分消化率、牛奶成分和甲烷排放的影响。根据PRISMA指南进行的这项分析表明，补充硫代葡萄糖苷导致牛奶尿素氮浓度呈二次方增加（P = 0.017）。此外，硫代葡萄糖苷水平与来源之间的显著相互作用影响了粗蛋白消化率（P = 0.026）。包括4%脂肪校正乳、能量校正乳、乳蛋白和乳糖比例在内的牛奶成分参数受到显著影响（P < 0.05）。此外，随着硫代葡萄糖苷摄入量的增加，甲烷排放（克/千克干物质采食量）呈二次方下降（P = 0.003），在日粮处理和动物种类之间还观察到额外的相互作用（P = 0.029）。丙酸和异丁酸浓度分别以二次方和线性方式增加（P < 0.05）。这些发现表明，含硫代葡萄糖苷的饲料可以提高反刍动物的养分利用率并减少甲烷排放。然而，这些影响的程度取决于硫代葡萄糖苷的剂量、来源、动物种类和日粮组成，需要进一步研究以优化它们在反刍动物营养中的使用。
