1凉山州乡镇畜牧兽医站的现状 1.1机构的设置及管理方式凉山州共有17个县(市),675个乡镇畜牧兽医站,其中中心站65个,乡镇站610个,设置原则是一乡镇一站.有11个县由于地域辽阔,交通不便,为了便于管理,设置了65个中心站.在管理体制上,"三权"归县的乡镇站有556个,"三权"下放的有119个.除西昌、昭觉、甘洛三县(市)外,其余14个县都实行"条块结合,以条为主"的管理模式.

凉山州是我国最大的彝族自治州,又是攀西地区的重要组成部分.位于四川省西南部,青藏高原东南部,属横断山脉、攀西大裂谷地带.由于地形复杂,立体气候明显,呈现出河谷南亚热带、中亚热带、北亚热带、山地暖温带、山地凉温带、高山寒冷带等多种不同的气候带.具有发展畜牧业得天独厚的自然条件.据2002年统计:全州大牲畜存栏150万头、猪存栏376.12万头、羊存栏467.97万只、禽存栏863万只;大牲畜出栏16.3万头,猪出栏328.56万头,羊出栏166.38万只,禽出栏1447万只;肉类总产量36.75万吨;牧业产值22.07亿元,占农业总产值的40%.

凉山州畜牧业已连续21年持续、稳定增长,为农村经济发展和社会稳定做出了重大贡献.然而,动物疫病仍是阻碍和制约凉山畜牧业健康发展的关键因素.当前,凉山州畜牧业的重点之一应是减少动物因疫病造成的损失.动物疫病防制是畜牧业面临的一项紧迫而又艰巨的任务.
