平原农区商品肉牛生产发展模式探讨（上）

Studies On Commercial Beef Cattle Production Models In Rural Areas In The Plain

平原在区肉牛生产正从传统、分散经营向商品化、规模化、集约化和系列化方向转化．已初步形成场户结合就地服育、异地肥育、生产－加工－销售一体化和商品肉半繁殖育肥场四种经营模式；氨化（碱化）秸秆＋糖料、青贮饲料＋材料、槽渣类饲料＋精料等三种有效饲养模式．本文在分析现有模式的基础上提出四种经营模式的适应区域、推广条件和发展趋势．并根据本人试验研究结果，参考国内外有关资料，提出完善上述三种饲养模式应以研制专用饲料添加剂、合理科学地使用埋植剂为主，并阐述了各种专用饲料添加剂的使用原理和组成。

The beef cattle production of the agricultural area in the plain is becoming from traditional and discrete to commercial,intensive,and integral.Four management models for beef cattle fattening came into being:Fattening beef cattle on the farm,of the farm,integration of production-processing-marketing, and commercial beefcattle breeding and fattening.Three feeding models were used,: ammoniated(alkalized)straw+concentrate,silage +concentrate and offal feed+concenrtate.On the basis of theanalysis of the present models,the authors suggested suitable areas,extension conditionsand future development for the four management models.On the basis of the trial resultsand with reference to information from home and abroad,the authors concluded that theabove-mentioned three feeding models should be perfected by mainly developing specific feed additives,and by scientifically using implants,and explained the action mode composition of various specfic feed additives.
