项目摘要

In the present experiment, the changes in mineral contents of soil, natural forages and blood of goats in and around Padang were investigated to clarify the constraint factors in animal production, in particular small ruminants in West Sumatra, Indonesia during consecutive 3 year, and the following results were obtained.1). The soils sampled in and around Padang were relatively low in the contents of nitrogen and phosphorus, and also thought to be poor in organic matter available for plant growth.2). In the nutrient contents of natural forages collected in and around Padang, there were no clear levels below critical level required for normal animal growth. However, Fe content in natural forages was clearly higher than that in other tropics and/or sub-tropics in the world. The S content in the forages was also quite high, and then a possibility was suggested that there would be low absorption of Cu in this area.3). In the mineral concentrations of blood of goats raised in and around Padang, Fe level is thought to be high, being rather excess level. The plasma levels of Cu and Mn in goat' blood collected in some areas were lower than the range suggested as normal level. In blood Se level, there was a quite big valiance, and then, in dry season the level in about 40 % of total animals subjected was deficient, and that in about 24 % of total animals subjected was excess. The plasma levels of Ca, S, Zn, Cu, Mo and Co were significantly different in the 2 seasons.4). From the results obtained in the feeding diets supplemented with legume tree leaves, there was obvious improvement in daily gain of growing kids due to increase in digestibility of crude protein and crude fiber. These findings clearly suggest that an efficient utilization of local feed resources would fairly contribute to improve an animal production in this area.These findings would contribute to make feeding systems for improving animal production in tropical areas in the world.

本试验连续3年对印尼西苏门答腊省巴塘及其周边地区的土壤、天然牧草和山羊血液中矿物质含量的变化进行了调查，以阐明影响畜牧业生产的制约因素，特别是小反刍动物生产的制约因素。巴塘及其周边土壤的氮、磷含量相对较低，可供植物生长的有机质含量也较低。在巴塘及其周边地区采集的天然牧草中，没有明显的营养水平低于动物正常生长所需的临界水平。然而，天然牧草中的铁含量明显高于世界上其他热带和/或亚热带地区。牧草中S含量也较高，说明该地区对Cu的吸收较低。在巴塘及其周边地区饲养的山羊血液中的矿物质浓度中，铁水平被认为是高的，是相当过量的水平。部分地区采集的山羊血液中铜、锰含量低于正常值范围。血硒水平有一个较大的波动，在旱季约有40%的动物血硒缺乏，约有24%的动物血硒过量。2个季节的血浆Ca、S、Zn、Cu、Mo、Co含量差异显著。从添加豆类树叶的饲粮中获得的结果来看，由于粗蛋白质和粗纤维消化率的增加，生长期羔羊的日增重有明显的改善。这些发现清楚地表明，有效地利用当地饲料资源将有助于提高该地区的动物生产，这些发现将有助于制定提高世界热带地区动物生产的饲养系统。
