为了解湖南省娄底市调入活羊及产品的来源和去向，对2018—2021年通过合法途径进入娄底市的活羊及产品进行市场链调查。结果显示：2018—2021年娄底市累计调入活羊637批次45 764只，其中省外调入248批次30 591只，涉及17个省（自治区、直辖市），有7个属布鲁氏菌病一类地区；14.3%的调入活羊再次进入饲养环节，其余全部用于屠宰。共调入羊产品1 430批次1 460.4 t，绝大部分为省外调入（1 411批次1 451.6 t），涉及17个省（自治区），其中14个属于布鲁氏菌病一类地区；调入产品以羊肉为主，占调入总数量的98.0%。活羊及产品调入均有明显季节性，每年从八九月份开始调入，数量及批次迅速增加，至次年1月达到高峰。结果表明：娄底市活羊及产品调入量较大，以省外为主，部分活羊及产品来自布鲁氏菌病一类地区，且有少量活羊进入饲养环节，由此带来的重大动物疫病传入风险不可忽视。建议加强活羊及产品的产地检疫，尤其是动物疫病多发地区，在秋冬季节加强对活羊及产品流通的管控，以降低小反刍兽疫、羊布鲁氏菌病等重大动物疫病的输入风险。
In order to investigate the source and destination of live sheep and their products introduced into Loudi City，Hunan Province，the market chain during 2018 to 2021 was investigated via legal means. The results showed that a total of 637 batches of 45 764 live sheep were introduced into Loudi，including 248 batches of 30 591 sheep from other provinces，involving 17 provinces（autonomous regions or municipalities），in which，7 were listed as brucellosis class I regions；14.3% introduced sheep were for feeding again，and others were for slaughter. A total of 1 430 batches and 1 460.4 tons of sheep products were introduced，most of which were from other provinces（1 411 batches of 1 451.6 tons），involving 17 provinces（autonomous regions），in which，14 were brucellosis class I regions；mutton was in the majority，accounting for 98.0%. Live sheep and their products were introduced depending on different seasons，which rapidly increased in quantity and batches since August or September every year and peaked in January next year. In conclusion，live sheep and their products were largely introduced into Loudi，mainly from other provinces，some of them from brucellosis class I regions，and a small number of live sheep were for feeding，which brought non-negligible entry risk of major animal diseases. Therefore，it was recommended to strengthen quarantine for live sheep and their products at the place of origin，especially in the areas where animal diseases were prevalent，and strengthen control over the circulation of live sheep and their products in autumns and winters to reduce potential entry risk of major animal diseases including peste des petits ruminants（PPR）and sheep brucellosis.
