Swine dysentery was eradicated from a 270 sow herd by using medication in conjunction with cleaning and disinfection, without reducing the herd size. The feed conversion efficiency, cost per kg liveweight gain and veterinary costs in the herd were compared with similar Meat and Livestock Commission recorded herds before swine dysentery entered the farm, while it was present and after its eradication. During the four years when the disease was endemic in the herd the feed conversion efficiency deteriorated by 0.58, equivalent to 7.31 pounds per pig, the cost per kg liveweight gain was 15 per cent higher and the costs of veterinary care and medicines were 1.38 pounds per pig greater. Although there were pigs with clinical swine dysentery in the herd during the four year period, the poor production figures were attributed mainly to subclinical disease. The cost of eradicating the disease was more than 20,000 pounds but this sum was recouped within 12 months by the improved production and reduced drug usage. The chances of success of such a programme have been estimated to be between 54 and 90 per cent.
通过药物治疗结合清洁与消毒措施，在不减少猪群规模的情况下，从一个拥有270头母猪的猪群中根除了猪痢疾。将该猪群的饲料转化率、每千克增重成本以及兽医费用，与猪痢疾传入农场之前、存在期间以及根除之后，肉类与家畜委员会记录的类似猪群进行了比较。在该病在猪群中流行的四年里，饲料转化率下降了0.58，相当于每头猪增加7.31磅，每千克增重成本高出15%，兽医护理和药品成本每头猪增加1.38磅。尽管在这四年期间猪群中有猪出现临床猪痢疾，但生产数据不佳主要归因于亚临床疾病。根除该疾病的成本超过20,000英镑，但通过生产改善和药物使用减少，这笔费用在12个月内就得到了弥补。据估计，这样一个项目成功的几率在54%至90%之间。
