Proliferative enteropathy (PE) is an enteric disease of pigs that results in diarrhoea, reduced growth rate, reduced feed conversion efficiency and sometimes death. A survey of 13 pig veterinary practitioners in Australia was conducted to determine: (1) PE control strategies (antibiotics and vaccination), (2) how the efficacies of these strategies are evaluated and (3) how reliance on antibiotics could be reduced by increasing vaccine adoption. Antibiotics were routinely prescribed in the diets of weaner, grower and finisher pigs by 9/13, 10/13 and 8/13 veterinarians, respectively, if vaccination was not implemented. Water-soluble antibiotics were prescribed less frequently than in-feed antibiotics. Efficacy of control strategies was assessed most often through reduced clinical signs (diarrhoea, 'tail-ender' pigs, death) and reduced lesion incidence at abattoir postmortem inspection. Twelve practitioners had recommended PE vaccination to their clients in the previous 6 months. Barriers to continued vaccine implementation included perceived lack of efficacy for pigs housed in bedded systems, high cost relative to medication and difficulties in vaccinating pigs post-weaning.
增生性肠炎（PE）是一种猪的肠道疾病，可导致腹泻、生长速度减慢、饲料转化率降低，有时还会导致死亡。对澳大利亚13名猪兽医从业者进行了一项调查，以确定：（1）PE控制策略（抗生素和疫苗接种），（2）如何评估这些策略的效果，以及（3）如何通过增加疫苗接种来减少对抗生素的依赖。如果不实施疫苗接种，断奶仔猪、生长猪和育肥猪日粮中分别有9/13、10/13和8/13的兽医常规开具抗生素。水溶性抗生素的开具频率低于饲料中添加的抗生素。控制策略的效果最常通过临床症状减轻（腹泻、“掉队”猪、死亡）和屠宰后尸检时病变发生率降低来评估。在过去6个月中，有12名从业者向其客户推荐了PE疫苗接种。持续实施疫苗接种的障碍包括认为对饲养在垫料系统中的猪无效、相对于药物成本高以及断奶后给猪接种疫苗存在困难。
