常绿岩垂草饲料营养价值研究

Study on the Nutritive Value of Lippia nodiflora(L. ) Greene as Feed

[目的]分析常绿岩垂草和过江藤的饲料营养价值。[方法]剪取过江藤和常绿岩垂草的地上茎叶,测定其营养指标,并与常用饲草进行比较,分析其作为饲草的开发价值。[结果]与过江藤相比,常绿岩垂草具有明显的速生与丰产能力。常绿岩垂草的粗脂肪、粗纤维、粗灰分、赖氨酸、维生素C、Ca、Fe含量明显高于过江藤,粗蛋白和全P含量明显低于过江藤。与常用饲草黑麦草、紫花苜蓿、谷草、玉米秸杆相比,常绿岩垂草具有较高的粗脂肪、粗灰分含量和较低的粗纤维、粗蛋白质含量。[结论]常绿岩垂草具有较高的饲料开发价值。

[ Objective ] The research aimed to analyze the feed nutritive value of Lippia nodiflora （ L. ） Greene and Lippia nodiflora （ L. ）. [ Method] The overground stem and leaves of L. nodiflora Greene and L. nodiflora were cut to measure the nutritive indices. And they were compared with common forage grass and the development value of L. nodiflora Greene was analyzed. [ Result] Compared with L. rwdiflora, L. nodiflora Greene had obvious fast-growing and high-yield abilities. The contents of crude fat, crude fiber, crude ash, lysine, vitamin C, Ca, and Fe in L. nodiflora Greene were obviously higher than that in L. nodiflora arm the content of crude protein and total P in L. nodiflora Greene were significantly lower than that in L. nodiflora. Compared with common forage feed ryegrass, alfalfa, aspartate and corn straw, L. nodiflora Greene had higher contents of crude fat and crude ash and lower contents of crude fiber and crude protein. [ Conclusion] L. nodiflora had higher development value as feed.
