作者利用舍饲全收粪法进行绵羊对红豆草青干草的消化试验,收集喂前草样,剩余草样和粪样;用自动绝热测热仪测定热能;计算红豆草的能量消化率和可消化能。营养期的能量消化率为63.16％,可消化能为11.56兆焦/公斤干物质;盛花期稍低为58.91％和10.86兆焦/公斤干物质;秸秆最低为44.70％和8.15兆焦/公斤干物质;衣子最高为79.12％和13.75兆焦/公斤干物质。明显表现出随红豆草的生长其能量消化率降低,可消化能减少。
The authors used the method of feeding and keeping all manure to carry out the digestion experiment of the sheep on the hay to the hay, and collected the grass samples, the remaining grass samples and the feces sample; the heat energy was measured by the automatic adiabatic calorimeter; the energy digestibility of the sainfoin was calculated Digestion energy. During the vegetative period, the energy digestibility was 63.16% and the digestible energy was 11.56 MJ / kg dry matter. The slightly lower flowering stage was 58.91% and 10.86 MJ / kg dry matter. The minimum straw was 44.70% and 8.15 MJ / kg dry Substances; Clothing up to 79.12% and 13.75 MJ / kg dry matter. Significantly reduced the digestibility of digestible energy as the saponin grows.
