项目摘要

This study investigates China's production and consumption of livestock food products, feed grain use during the 1979-99 period, as well as the effects of growing livestock product consumption on grain supply or farmland use.1. Using the adjusted 1996 livestock statistics by China's State Statistical Bureau, this study links the livestock statistics before and after 1996. By comparing the production with consumption of meat products, this study also examines the possibility and degree of over-estimation in livestock product statistics, and re-estimates the meat production, using the adjusted number of slaughtered animals and weight rates of dressed carcass to livestock. The estimated 1999 meat production is lower than livestock statistics by 4.4 million tons, or 7.4%.2. The feed efficiency is examined at province average and farm household levels. The results indicate that the ratios of average dressed carcass weight to feed grain use in swine and poultry (layers) have risen by 45% and 91% respectively, from 1979 to 1999. Technical progress, the share growth of herbivorous livestock, and a relatively large percentage of small farmers with traditional livestock practices that effectively use leftover food and farm by-products, have greatly contributed to feed grain saving.3. The estimation results show that the share of feed grain in grain production steadily increased by about 16% in 1979 to 35% in 1999.

本研究调查了1979-99年间中国畜牧产品的生产和消费、饲料粮的使用情况，以及不断增长的畜产品消费对粮食供应或耕地利用的影响。1．本研究利用中国国家统计局调整后的1996年畜牧业统计数据，将1996年前后的畜牧业统计数据联系起来。通过比较肉类产品的生产和消费，本研究还检验了畜牧业产品统计数据高估的可能性和程度。并使用调整后的屠宰动物数量和屠体与牲畜的重量比重新估计肉类产量。估计 1999 年肉类产量比牲畜统计数字低 440 万吨，即 7.4%。2。饲料效率是在全省平均水平和农户水平上进行检验的。结果表明，从 1979 年到 1999 年，猪和家禽（蛋鸡）的平均胴体重量与饲料用量的比率分别上升了 45% 和 91%。大量采用传统畜牧业的小农户有效利用剩余粮食和农副产品，为节省饲料粮做出了巨大贡献。3．测算结果显示，饲料粮在粮食生产中的比重稳步上升，从1979年的16%左右上升到1999年的35%。
