利用山区与平原气候差异生产优质肉羊

Production of Quality Lamb Meat by Use of Different Climatic Resources Between Mountain Areas and Flatlands

山区和平原的气候差异造成饲草资源量高峰期的季节差异。利用这种饲草资源量的时间差特点，夏季在山区繁育羔羊，秋季将断奶羔羊移至平原农区育肥，形成新的优质肉羊生产体系。具有下列特点：改善山区羊群结构，提高商品率，增加经济效益；减轻山区冬春季节草畜矛盾，保护生态环境；充分利用山区草场资源、平原农区秸秆资源，发展节粮型畜牧业；生产优质羔羊肉供应市场；秸秆过腹还田，培肥土壤，提高粮食产量。

There was an obvious seasonal difference for grass growth between mountain areas and flatlands due to the climatic differences.Thorefore,a new production system of quality lamb meat was developed,i.e., breeding lambs in summer in mountain areas,then transferring the weaned lands to flatlands to quickly fatten them after grass withered up in autumn .The advantages are as follows;a) to improve the goat population structure in mountain areas and increase commodity rate and economic benefit;b) to solve the problem of forage shortage in winter and spring,and protect the ecological environment in mountain areas;c) to fully utilize the grass resource in the mountain areas and the plant stalks resource in flatlands and develop animal husbandry for grain saving;d) to produce more quality lamb meat for the market;e)to return stalks to land after digested by animal,and fertilize the soil.
