为提高昭苏马场牧草供应并改善牧草品质及消化能,于2013年对昭苏地区不同混播比例下的燕麦(Avena sativa)与箭筈豌豆(Vicia sativa)混播牧草的产量、营养品质及马对牧草的消化能进行了研究。结果表明,随着箭筈豌豆比例的增加,牧草产量、叶茎比、粗蛋白、Ca含量与消化能浓度呈上升趋势,而中性洗涤纤维、酸性洗涤纤维和粗脂肪含量呈下降趋势,P含量变化不明显;与单播相比,各混播组合牧草产量、粗脂肪显著高于单播箭筈豌豆(P<0.05),而粗蛋白、Ca含量显著高于单播燕麦,各混播组合的土地当量比均高于单播。营养物质产量与消化能产出具有相似规律。此外,利用不同类型马的营养物质需求对燕麦与箭筈豌豆混播草地进行生产性能评价,其结果与用牧草产量评价是有差异的。本研究表明,利用草地消化能产出及营养物质产量与马日需求量的相对差额评价草地生产性能,其结果可较好地反映燕麦-箭筈豌豆混播草地与马营养需求间的关系。
In order to improve pasture supply and improve forage quality and digestion energy in Zhaosu Farm, in 2013, the yield, nutritional quality and quality of mixed forage grasses (Avena sativa and Vicia sativa) The digestion energy of forage was studied. The results showed that the forage yield, leaf-stem ratio, crude protein, Ca content and digestible energy concentration increased with the increasing proportion of arrowhead pea, while the content of neutral detergent fiber, acid detergent fiber and crude fat decreased. P Compared with unicast, the forage yield and crude fat of the mixed-cropping forage were significantly higher than that of the uniaxial arrow Pea (P <0.05), but the content of crude protein and Ca was significantly higher than that of the unicast oat The land equivalent ratio is higher than unicast. Nutrient yield and digestible energy output have similar rules. In addition, the production performance of oat and arrow 筈 peas mixed grassland was evaluated by different types of horses. The results were different from those of forage grazing. The results showed that using the relative difference between the output of digestive energy of grassland and the yield of nutrients and the demand of horse day to evaluate the performance of grassland, the results could well reflect the relationship between the nutrition requirement of oat-arrowhead pea mixed-sown grassland and horse.
