传染性细菌性疾病、腐蹄病和烫伤病仍然是英国羊群跛行的最常见原因，估计有 300 万只羊曾一度跛行（农场动物福利委员会 (FAWC) 2011）。跛行是整个绵羊行业面临的主要动物福利和经济挑战，估计给该行业造成了 2400 万英镑的损失（Nieuwhof 和 Bishop 2005），并且可以被视为可持续生产的巨大障碍。 2011 年 FAWC 关于绵羊跛行的意见设定了到 2016 年将跛行率减少到 5% 以下、到 2021 年减少到 2% 以下的目标 (FAWC 2011)。本研究的目的是开发和验证可实现的农场级解决方案，即“五点计划”，以将跛行水平降低到 FAWC 目标。“五点计划”是利用现有已发表的有关绵羊跛行的科学知识以及实现持续低跛行水平的农民的实践经验制定的。五点计划有五个行动点，以三种不同的方式支持动物：增强抵御能力、减少疾病挑战和建立免疫力（图 1、表 1）。随后，“五点计划”在英国一家养羊场实施了为期四年的研究（2009-2013 年）。研究时间的长短考虑到了跛行水平自然发生的季节性和年度变化。
The infectious bacterial diseases, footrot and scald, are still the most prevalent causes of lameness in sheep flocks in the UK, with an estimated 3 million sheep being lame at any one time (Farm Animal Welfare Council (FAWC) 2011). Lameness constitutes a major animal welfare and economic challenge across the sheep sector, costing an estimated£ 24 million to the industry (Nieuwhof and Bishop 2005), and can be seen as a considerable barrier to sustainable production. The 2011 FAWC opinion on sheep lameness set a target of reducing lameness to less than 5 per cent by 2016, and to less than 2 per cent by 2021 (FAWC 2011). The aim of this study was to develop and validate an achievable farm-level solution, the Five Point Plan, to reduce lameness levels to FAWC targets.The Five Point Plan was developed using existing published science on sheep lameness, and practical experience from farmers who had achieved sustained low levels of lameness. The Five Point Plan has five action points that support the animal in three different ways: building resilience, reducing disease challenge and establishing immunity (Fig 1, Table 1). The Five Point Plan was then implemented on a UK sheep farm over a four-year study period (2009–2013). The length of the study period allowed for naturally occurring seasonal and annual variations in lameness levels.
