Fermented liquid feed (FLF) protects broiler chickens against colonisation with Salmonella. While Campylobacter causes more disease cases in humans than Salmonella, the effect of FLF on Campylobacter was assessed. The fermented liquid feed is a moistened feed with a high number of lactobacilli, a high concentration of lactic acid, and a pH of 4. In three experiments Campylobacter was orally applied to individually housed 9-day-old broiler chickens. A significant reduction of susceptibility, as determined by cloacal swabs, was observed. At any moment where an animal has not started to shed Campylobacter yet, the probability to start shedding Campylobacter in a subsequent small time interval was nine times as high for the control chickens than for the animals that were fed FLF. FLF did not consistently change the Campylobacter colonisation level in the caeca. It was concluded that FLF could reduce the probability of introduction of Campylobacter in broiler flocks. In an experiment where some chickens were simultaneously inoculated with Salmonella enteritidis and Campylobacter, no interaction on susceptibility or caecal colonisation level was observed.
发酵液体饲料（FLF）可保护肉鸡免受沙门氏菌的定植。虽然弯曲杆菌在人类中引起的疾病病例比沙门氏菌更多，但评估了FLF对弯曲杆菌的影响。发酵液体饲料是一种含有大量乳酸杆菌、高浓度乳酸且pH值为4的湿润饲料。在三项实验中，将弯曲杆菌口服接种到单独饲养的9日龄肉鸡中。通过泄殖腔拭子检测发现易感性显著降低。在任何动物尚未开始排出弯曲杆菌的时刻，在随后的小时间间隔内开始排出弯曲杆菌的概率，对照鸡是喂食FLF的动物的九倍。FLF并未持续改变盲肠中弯曲杆菌的定植水平。得出的结论是，FLF可以降低肉鸡群中引入弯曲杆菌的概率。在一项实验中，一些鸡同时接种肠炎沙门氏菌和弯曲杆菌，未观察到对易感性或盲肠定植水平的相互作用。
