The growth rates of 458 finishing pigs between 25 kg and 107 kg liveweight, which were offered finely ground pelleted feed ad libitum, were determined and their stomachs were examined at slaughter. Two herds were involved and a macroscopical examination of the mucosal lesions in the pars oesophagea revealed a prevalence of 75 per cent of the 274 pigs in herd A and 89 per cent of the 184 pigs in herd B with hyperkeratosis of the pars oesophagea, and approximately 11 per cent of the pigs in both herds with extensive erosions and/or ulceration; on average the pigs with extensive lesions gained 50 to 75 g/day less weight than the pigs with no lesions in the pars oesophagea. There was no difference between the prevalence of the oesophagogastric lesions of different severity between barrows and gilts, but there was evidence for differences between litters.
测定了458头体重在25千克至107千克之间的育肥猪的生长速度，这些猪随意采食精细粉碎的颗粒饲料，并在屠宰时检查它们的胃部。涉及两个猪群，对A群274头猪和B群184头猪食管部黏膜病变进行宏观检查发现，A群猪食管部角化过度的患病率为75%，B群为89%，两群中约11%的猪有广泛糜烂和/或溃疡；平均而言，食管部有广泛病变的猪比食管部无病变的猪每天少增重50至75克。阉猪和后备母猪之间不同严重程度的食管胃病变患病率没有差异，但有证据表明不同窝之间存在差异。
