加快四川省优质黄羽肉鸡的发展

“十五”期间，国家对西部地区开发战略的倾斜与实施，给优质黄羽肉鸡生产发展提供了一个新的机遇。由于西部开发战略的切入点是生态环境保护和建设，开发的关键是产品结构调整，这方面尤以畜牧业的发展引人关注。其中的黄羽肉鸡更有节粮型畜牧业之优点。四川省畜牧业产值占西部地区10省中畜牧业总产值的41％，表明四川省畜牧业的作用和贡献是很大的。因此，在今后的几年中，抓住大好时机，努力发展肉鸡生产，特别是优质黄羽肉鸡业，使其尽快走上一个新的台阶，这是养鸡工作者的一大光荣之事。     

试论我国西部地区绿色肉兔生产基地建设

畜牧业作为我国西部地区农村经济的重要支柱，产值在西部地区农业总产值中占相当大的比重。肉兔养殖仍然是畜牧业的重头戏。但是，随着中国“入世”，人民生活水平的提高和人们对食品安全、身体健康的关注．我国西部地区养兔业已很不适应日趋激烈的市场竞争和广大城乡居民日益提高的消费需求。一是兔品种改良步伐缓慢，肉品质量差，导致外销不畅，价格低迷；

怎样从根本上治理被破坏的草地

西部地区是我国天然草地资源集中分布的地区,有天然草地3.273亿公顷,占西部国土面积的一半,占全国草地资源面积的83.32％,是我国传统的畜牧业基地,也是长江、黄河的上游区和发源地。草地畜牧业一直是我国西部地区的主体产业之一,为边疆建设、牧区繁荣和中华各民族团结进步,做出了突出贡献;作为我国主要陆地生态系统之一的西部地区天然草地,     

以科技和现代管理方式来提高西部地区畜牧业的发展

畜牧业已经成为推动农业和农村经济发展的主力，尤其西部地区的畜牧业发展，在我国畜牧业中占有重要地位。但是在西部地区的畜牧业发展中还存在一些急需解决的问题：畜牧业生产不适应规模化、产业化大发展的要求；优质畜禽产品少，品种单一，不能满足市场需求；西部一些地区由于薄弱的经济基础和粗放的经营管理，草地畜牧业经济还比较落后，与快速的经济发展不相适应，影响了该区内经济发展。因此，加快转变发展方式，科学确定以科技和现代化管理的手段，促进西部地区草地畜牧业的产业化发展，建立新型畜牧业科技研发、转化和推广体系，对促进民族地区经济又好又快发展具有重要的战略意义。
