英文摘要 | In order to study forage mixture skills and solve livestock's nutrient deficiency for the adaptive development of grassland stockbreeding in the karst rocky desertification areas, this paper chose the alfalfa (Medicago sativa) and rescuegrass (Bromus catharticus) which grow well in the karst areas for the nutrition degradability measurements of six castrative Guizhou white goats installed perpetual rumen fistula by Nylon Bag Technique. Test group is 100% rescuegrass (Control group I), 10% alfalfa and 90% rescuegrass (Experiment group I), 30% alfalfa and 70% rescuegrass (Experiment group II), 50% alfalfa and 50% rescuegrass (Experiment group III), 70% alfalfa and 30% rescuegrass (Experiment group IV), 90% alfalfa and 10% rescuegrass (Experiment group V) and 100% alfalfa (Control group II). The results indicate that the degradation rate to dry matter (DM) of the mixed forage is bigger than that of single forage; the degradation rate of crude protein (CP) is increasing with percentage of legume; there is no obvious variation tendency of the degradability of neutral detergent fiber (NDF) and acid detergent fiber (ADF). However, the degradation rate in experiment group II is the biggest. The comprehensive analysis for digestion and utilization situations of the white goats with the forages above shows that the nutrition conversion of the mixed forage is bigger than that of the single forage; the best mixture percentage between legume and grasses forage is 3:7. As a result, we suggest this configuration proportion in the grass land construction and the grassland stockbreeding development of the national rocky desertification control. |
