一、发达的畜牧业是经济发展的必然结果 农业是人类社会最古老的生产部门。农业生产的实质就是人运用生物进行再生产的过程。人类文明就从农业开始。它经过漫长的发展历史,经历了原始农业、传统农业和现代农业三个阶段。 农业生产以生物作转化工具,将农业资源转化成农产品,形成农业的转化系统。向农业系统中输入的基本资源是光、热、水、气和各种养份,输出的产品是粮食、牧草、油料、肉、奶、蛋和畜力。这种输入和输出的转化过程不断循环。所以叫农业循环转化系统。
First, advanced animal husbandry is an inevitable result of economic development Agriculture is the oldest production sector in human society. The essence of agricultural production is the process by which people use organisms for reproduction. Human civilization begins with agriculture. After a long history of its development, it has experienced three stages: primitive agriculture, traditional agriculture and modern agriculture. Agricultural production is a biological conversion tool that converts agricultural resources into agricultural products and forms a system of agricultural transformation. The basic inputs to the agricultural system are light, heat, water, gas and various nutrients, and the output is food, pasture, oil, meat, milk, eggs and animal power. This input and output conversion process is constantly cycling. So called agricultural cycle transformation system.
