Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth‘s surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a ‘capital reserve‘ that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world‘s meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo | | 出版日期 | Conference proceedings 1980 | | 关键词 | physiology | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-011-8067-2 | | isbn_softcover | 978-94-011-8069-6 | | isbn_ebook | 978-94-011-8067-2 | | copyright | MTP Press Limited 1980 |
