The study aimed to determine the optimal ratio for the mixture of forage cactus and corn stover silage, emphasizing the evaluation of fermentative profile, microbial populations, dry matter losses, chemical composition, and aerobic stability. A completely randomized design with four treatments and five replications was employed in this study. Treatments included varying proportions of forage cactus in corn stover at ensiling (0%, 10%, 20%, and 40% of fresh matter). After a 100-day fermentation period, the assayed variables underwent regression analysis. Forage cactus inclusion led to linear dry matter and ether extract reductions, with crude protein showing a negative quadratic effect (p < 0.05). The pH and water-soluble carbohydrates exhibited negative quadratic effects with the increasing proportion of forage cactus (p < 0.05). Lactic and acetic acids exhibited quadratic effects, reaching their peaks at approximately 20% forage cactus (p < 0.05). Lactic acid bacteria demonstrated a linear decrease, while yeasts/molds displayed a negative quadratic effect (p < 0.05). Dry matter losses followed a quadratic pattern, with the minimum values observed at 20% forage cactus (p < 0.05). Additionally, the inclusion of forage cactus significantly enhanced aerobic stability (p < 0.05). The incorporation of 20% forage cactus into corn stover silage markedly improved its quality.

该研究旨在确定饲用仙人掌和玉米秸秆青贮饲料混合物的最佳比例，重点评估发酵特性、微生物种群、干物质损失、化学成分和需氧稳定性。本研究采用完全随机设计，包括四种治疗和五次重复。处理方法包括青贮时在玉米秸秆中添加不同比例的饲料仙人掌（新鲜物质的 0%、10%、20% 和 40%）。经过 100 天的发酵期后，对测定的变量进行回归分析。饲料仙人掌含量导致干物质和乙醚提取物线性减少，粗蛋白呈现负二次效应（p  < 0.05）。随着饲用仙人掌比例的增加，pH 值和水溶性碳水化合物表现出负二次效应（p  < 0.05）。乳酸和乙酸表现出二次效应，在大约 20% 饲料仙人掌中达到峰值 ( p  < 0.05)。乳酸菌表现出线性下降，而酵母/霉菌表现出负二次效应（p  < 0.05）。干物质损失呈二次方模式，在 20% 饲料仙人掌中观察到最小值 ( p  < 0.05)。此外，饲料仙人掌的加入显着增强了有氧稳定性（p  <0.05）。玉米秸秆青贮饲料中掺入20%饲用仙人掌，其品质显着提高。
