A telephone survey of farmers was conducted to determine current internal parasite control practices on sheep farms in Spain; the farmers were interviewed by their veterinarians. Anthelmintic choice was largely on veterinary advice and dominated by benzimidazoles and macrocyclic lactones. Anthelmintic rotation was separated into: no rotation (42% of farms); annual rotation (36%); rotate within year (20%); and rotate every second year (2%). The mean annual number of treatments varied subtly by region; ewes and rams 1.6-2.1, replacement lambs 1.7-2.1. Anthelmintics are administered primarily during spring and early summer (47% of treatments), and autumn (41%). Thirty-two percent of farmers introduced sheep to their properties and more than half did not quarantine drench the arrivals.
对西班牙绵羊养殖场的农民进行了电话调查，以确定当前的内部寄生虫控制措施；农民由他们的兽医进行了访谈。驱虫药的选择主要取决于兽医的建议，以苯并咪唑类药物和大环内酯类药物为主。驱虫药的轮换分为：不轮换（42%的农场）；每年轮换（36%）；年内轮换（20%）；每两年轮换（2%）。按地区划分，每年的平均治疗次数略有不同；母羊和公羊 1.6-2.1，后备羔羊 1.7-2.1。驱虫药主要在春季和初夏（47%的治疗）和秋季（41%）使用。32%的农民将绵羊引入他们的农场，超过一半的农民没有对新来的绵羊进行检疫和驱虫。
