Diarrhea in pigs has the potential to have a serious economic impact on the swine industry. Previously, we suggested that the likely cause of the presence of non-infectious diarrhea in pigs characterized by lactate accumulation was dyspepsia. In this experiment, the prevalence of enteropathogens and hyper-lactate accumulation in feces of piglets in 4 distinct growth stages was examined. The feces were collected when veterinarian experts recognized abnormalities in sporadic outbreaks. Prevalence of enteropathogens in diarrheal feces was 100% in fattening pigs (FP), 75% in weaning pigs (WP), 50% in suckling pigs (SP), and 42% in growing pigs (GP). Prevalence of enteropathogens in loose feces was 53% in WP, 50% in SP, 40% in FP, and 28% in GP. Prevalence of hyper-lactate accumulation in diarrheal feces was 33% in GP, 33% in SP, 25% in WP, and 25% in FP. Prevalence of hyper-lactate accumulation in loose feces was 40% in GP, 0% in SP, 7% in WP, and 5% in FP. Accordingly, non-infectious dyspepsia is frequent in growing pigs. In this period, pigs are potentially exposed to needless antimicrobial therapeutic treatments in sporadic cases.
猪腹泻有可能对养猪业造成严重的经济影响。此前，我们认为，以乳酸积累为特征的非传染性腹泻的可能原因是消化不良。在本实验中，检测了 4 个不同生长阶段仔猪粪便中肠病原体和高乳酸积累的流行情况。当兽医专家发现散发性暴发异常时，采集粪便。在育肥猪（FP）中，腹泻粪便中肠病原体的流行率为 100%，在断奶仔猪（WP）中为 75%，在哺乳仔猪（SP）中为 50%，在生长猪（GP）中为 42%。WP 中稀便中肠病原体的流行率为 53%，SP 中为 50%，FP 中为 40%，GP 中为 28%。腹泻粪便中高乳酸积累的流行率为 33%，SP 中为 33%，WP 中为 25%，FP 中为 25%。稀便中高乳酸积累的流行率为 40%，SP 中为 0%，WP 中为 7%，FP 中为 5%。因此，非传染性消化不良在生长猪中很常见。在此期间，猪在散发性病例中可能会受到不必要的抗菌治疗。
