Abstract

Livestock plays an important role in sustaining rural livelihood, nutritional and environmental security and growth of Indian Agriculture. Fodder trees are an important feed for livestock, particularly during dry months and flood season when all the other fodder sources have been exhausted. Commonly available fodder tree leaves used as goat forage such as Ficus rumphii and Streblus asper and Litsea monopetela from flood plains of Assam were selected to determine the content of proximate principles, macro- and micro-nutrients and anti-nutritional factors. Considerable variations were observed in the nutrient profile of the studied species. Micro-minerals such as Cu, Zn and Co were lower than required level, while the content of macro-minerals viz ., Ca, Mg and P was higher than required level. Saponin was not detected in any of the three species. Based on the nutrient content of the three selected species, it was concluded that either of them can be used as a source of forage for ruminants, especially during the period of scarcity.
印度阿萨姆邦洪泛平原三种选定树种叶片的营养成分
牲畜在维持农村生计、营养和环境安全以及印度农业增长方面发挥着重要作用。饲料树是家畜的重要饲料,特别是在干旱月份和洪水季节,当所有其他饲料来源都已耗尽时。选取阿萨姆邦洪泛平原常用的山羊饲料树叶片,如榕叶、山杨叶和山核桃叶,测定其近似原理、宏量和微量营养素及抗营养因子含量。在被研究物种的营养状况中观察到相当大的变化。微量元素Cu、Zn、Co含量低于需要量,而大量元素Ca、Mg、P含量高于需要量。三种植物均未检出皂苷。根据所选三种植物的营养成分,认为它们都可以作为反刍动物的饲料来源,特别是在资源稀缺时期。
