An experiment was carried out to compare the use of fresh cactus with cactus ensiled with and without a microbial inoculant in sheep diets by examining their feed intake, nutrient digestibility, nitrogen balance, and microbial protein synthesis and counting fecal enterobacteria. Twenty uncastrated mixed-breed sheep at approximately six months of age, with an average initial weight of 23.48 ± 2.40 kg, were used in the study. The animals were assigned to four treatments [fresh spineless cactus processed twice daily at the time of supply (FC2); fresh spineless cactus processed only once, in the morning, and supplied twice daily (FC1); spineless-cactus silage without inoculant (CS); and spineless-cactus silage with microbial inoculant (CSI)] in a completely randomized design with five replications per treatment. The experimental period was 21 days. The use of spineless cactus in the form of silage (CS and CSI) resulted in higher (P < 0.05) intakes of dry matter, organic matter, neutral detergent fiber, ether extract, non-fibrous carbohydrates, and total digestible nutrients; and higher digestibility coefficients of dry matter, organic matter, and total digestible nutrients. Lower counts of fecal enterobacteria were also observed with the ensiled cactus. By contrast, the diets did not influence (P> 0.05) nitrogen balance, microbial efficiency, urinary nitrogen losses, or fecal nitrogen losses. Regardless of inoculation, the ensiling of spineless cactus improves the sanitary quality of the diet, reducing the amount of enterobacteria in the cactus and resulting mainly in improved nutrient intake by sheep.

进行了一项实验，通过检查饲料中的饲料摄入量，养分消化率，氮平衡和微生物蛋白合成并计算粪便肠细菌的数量，来比较新鲜仙人掌和含或不含微生物接种剂的青贮仙人掌的使用。在研究中使用了大约六个月大的二十只未cast割的混种绵羊，平均初始体重为23.48±2.40 kg。将动物分配至四种处理[在供应时每天两次处理的新鲜无脊椎仙人掌；新鲜的无脊椎仙人掌在早上只加工一次，每天供应两次（FC1）；无接种物的无脊椎青贮（CS）; 和无菌仙人掌青贮与微生物接种剂（CSI）]，采用完全随机设计，每次处理重复五次。实验期为21天。以青贮饲料（CS和CSI）的形式使用无脊椎仙人掌会导致摄入更多（P <0.05）的干物质，有机物质，中性洗涤剂纤维，乙醚提取物，非纤维碳水化合物和总可消化营养素；以及较高的干物质，有机物质和总可消化营养物的消化系数。青贮的仙人掌也观察到粪便肠细菌的数量减少。相比之下，饮食不影响（P> 0.05）氮平衡，微生物效率，尿液氮损失或粪便氮损失。无论接种何种疫苗，无脊椎仙人掌的集装都可以改善饮食的卫生质量，减少仙人掌中肠细菌的数量，并主要提高绵羊的营养摄入量。
