In four experiments a total of 288 individually fed pigs were given barley-based diets for about 100 days from about 20 kg liveweight. Fine grinding of barley increased the number and severity of oesophagogastric lesions. Pelleting a diet based on coarsely ground barley had a similar effect. Coarser grinding of the barley and substituting small proportions of oat husk, but not of bran, gave lower incidences and severities of lesions. The performance responses of the pigs differed and give a framework for deciding on the balance to be struck between optimal performance and the risk of lesion development.
在四项试验中，共有288头单独饲养的猪从约20千克活重开始，食用以大麦为基础的日粮约100天。大麦的精细研磨增加了食管胃病变的数量和严重程度。将基于粗磨大麦的日粮制成颗粒饲料也有类似效果。大麦的粗磨以及用小比例的燕麦壳而非麸皮替代，可降低病变的发生率和严重程度。猪的生产性能反应有所不同，为在最佳生产性能与病变发生风险之间达成平衡的决策提供了一个框架。
