The impact of Sarcoptic mange on sows and on performance of their offspring from birth to slaughter was determined. Sows naturally infested with Sarcoptic mange were paired, mated to the same boar, and assigned randomly to treated or control farrowing groups. Treated sows received ivermectin s.c. at 300 micrograms/kg body weight; control sows received the vehicle s.c. Sow performance was evaluated via sow feed consumption, litter size, litter birth weights, litter weaning weights and piglet death loss from birth to weaning. Seven replicates (farrowing groups), each with six sow pairs, were included in the trial. Offspring from treated and control sows, 35 head/group, were fed to slaughter weights. Untreated sows had litters that weighed 4.14 kg less than ivermectin-treated sow litters at 21 d (P less than .07). Treated sows consumed 1.95 kg less feed per weaned piglet and .13 kg less feed per kilogram of weaned piglet (P less than .05). Piglets from treated sows were 5.79 kg/head heavier at slaughter (P less than .05) and had a .05 kg/d superior average daily gain (P less than .05).
确定了疥螨病对母猪及其后代从出生到屠宰性能的影响。将自然感染疥螨病的母猪配对，与同一头公猪交配，并随机分配到治疗组或对照组产仔群。治疗组母猪皮下注射伊维菌素，剂量为300微克/千克体重；对照组母猪皮下注射赋形剂。通过母猪采食量、产仔数、仔猪出生体重、仔猪断奶体重以及从出生到断奶的仔猪死亡损失来评估母猪的性能。试验包括7个重复（产仔群），每个重复有6对母猪。将治疗组和对照组母猪的后代各35头饲养至屠宰体重。未治疗的母猪所产仔猪在21日龄时比伊维菌素治疗组母猪所产仔猪轻4.14千克（P小于0.07）。治疗组母猪每头断奶仔猪的采食量比对照组少1.95千克，每千克断奶仔猪的采食量少0.13千克（P小于0.05）。治疗组母猪的仔猪在屠宰时体重比对照组重5.79千克/头（P小于0.05），平均日增重比对照组高0.05千克/天（P小于0.05）。
