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.
