Looking Back and Leaping Forward the Animal Husbandry Engineering

Intensive animal production has developed rapidly in the suburb of big cities in the past ten years, and also taken a great advance in engineering-technology in this field in China. It means that Chinese agricultural engineers have the ability to design, construct, and manufacture all the modernized buildings and facilities for factory animal production.Complete confinement system, high investment, high energy consumption and fine concentrated feed are not fit the conditions of China at present time. All the costs for the engineering measures to be used in the animal industry in China at present time should be paid by the industry itself. So, the agricultural engineer has to consider what kind of engineering measures can be used on a certain factory animal farm.As a great amount of animal wastes will be excreted from factory animal farm every day, there must be certain appropriate facilities to treat them to avoid the environmental pollution of the city. If there are no or not enough such facilities it will be dangerous to extremely stress the self-supporting of meat, eggs and milk for the city itself.The efficiency of animal industry should only be measured by the performance of livestock or poultry production, but not by the level of machinization on the farm in any cases.The best way of developing the animal industry in China is to combine it with agriculture in the same region.
