烧焦的平原仙人掌被评估为牛 饲料在为期84天的饲养试验中， 分别饲喂2.3%的干草和棉籽粕的基础日粮 初始体重。每对中的一只小母牛也吃烧焦的 仙人掌随意提供。花椒增加总干 物质消耗43%，增重72%。小母牛 在试验期间或随后的60天内， 在仙人掌山脉的日子化学分析和微量消化 试验表明，刺梨的消化率相等， 上级优于优质苜蓿干草。含有花椒 比苜蓿干草多40%的可溶性碳水化合物， 仅含有3.4%的可消化蛋白质。因此，含有 仙人掌通常需要补充蛋白质。 我们得出的结论是，烧焦的仙人掌是一个可口的 和营养饲料，应作为额外的评估 在短草区觅食。
Singed plains pricklypear was assessed as a cattle forage. In an 84-day feeding trial, six pairs of heifers were individually fed a basal ration of hay and cottonseed meal at 2.3% of initial bodyweight. One heifer in each pair also ate singed pricklypear offered ad libitum. Pricklypear increased total dry matter consumption 43% and weight gain 72%. The heifers experienced no digestive problems during the trial or ensuing 60 days on pricklypear range. Chemical analyses and microdigestion trials indicated that digestibility of pricklypear was equal or superior to that of high quality alfalfa hay. Pricklypear contained about 40% more soluble carbohydrates than alfalfa hay, but contained only 3.4% digestible protein. Therefore, rations containing pricklypear would usually require protein supplementation. We concluded that singed pricklypear was a palatable and nutritious feed and should be evaluated as an additional forage on shortgrass range.
