摘要
为了研究喀斯特山区常见野生牧草艾蒿、扁穗雀麦、早熟禾、牛筋草、荩草、地八角、马塘草、狗尾草与青贮饲料配合饲喂贵州无角黑山羊的增重效果,试验测定了各牧草品种的株高、产量、适口性以及营养成分,对比分析了A组(艾蒿+地八角+青贮料)、B组(扁穗雀麦+地八角+青贮料)、C组(早熟禾+地八角+青贮料)、D组(牛筋草+地八角+青贮料)、E组(荩草+地八角+青贮料)、F组(马塘草+地八角+青贮料)、G组(狗尾草+地八角+青贮料)7个饲喂组合对贵州无角黑山羊(每组10只)增重效果和经济效益的影响。结果表明:扁穗雀麦株高和产量最高,地八角、早熟禾、牛筋草适口性较好且蛋白质含量较高;以扁穗雀麦、艾蒿、牛筋草、早熟禾4种牧草搭配饲喂贵州无角黑山羊增重效果较好,日增重为143.90~163.70 g,日纯收入为4.03~4.74元,投出产出比为1∶5.12~1∶4.50。说明扁穗雀麦、艾蒿、牛筋草、早熟禾4种牧草作为饲养黑山羊的牧草资源具有较好的饲用价值,可应用于种草养羊示范与推广。
In order to investigate the weight gain effect of common wild pasture(Artemisia indica Willd, Bromus catharticus, Poa pratensis L, Elensine indica, Arthraxon hispidus(thumb) Makino, Astragalus bhotanensis, Digitaria sanguinalis and Setaria viridis) mixed with silage feed to Guizhou hornless black goat in the Karst Mountains, the effects of seven feeding combinations(10 in each group, group A: Artemisia indica Willd+Astragulus bhotanesis+silage, group B:Bromus catharticus + Astragalus bhotanesis + silage, group C: Poa pratensis L.+ Astragalus bhotanesis + silage, group D: Elensine indica + Astragalus bhotanesis + silage, group E: Arthraxon hookeri H. + Astragalus bhotanesis + silage, group F: Digrtaria sanguinalis+ Astragalus bhotanesis + silage, group G: Setaria viridis + Astragalus bhotanesis + silage) on weight gain effect and economic benefit of Guizhou hornless black goats were compared and analyzed based on the determination of plant height, yield, palatability and nutrient composition of each forage variety in this experiment. The results showed that the plant height and yield of Bromus catharticus were the highest, the appetites of Poa pratensis L., Elensine indica, and Astragalus bhotanesis were better, and the protein content of Poa pratensis L., Elensine indica, and Astragalus bhotanesis were higher, the weight gain effect of the combination of four kinds of herbage feed to Guizhou hornless black goat were better, daily gain was 143.90 g to 163.70 g, the daily net income was 4.03 to 4.74 yuan, and the input-output ratio was 1∶5.12 to 1∶4.50. These results indicated that these four kinds of pasture have good feeding value for black goats and can be used for demonstration and promotion.
