“…Enterotoxigenic Escherichia coli proliferation is considered as one of the main causes of post-weaning diarrhea in pigs [33]. However, Campylobacter species, especially C. coli was also isolated from piglets and grower/finisher pigs with diarrhea [34,35]. In agreement with these studies, we also found a significant increase in Campylobacter in 7-day post-weaned pigs with diarrhea.…”

Weaning is a crucial period when piglets have to cope with sudden dietary, social, and environmental stressors that often lead to serious intestinal dysbiosis and mortality. In this study, five mucosal and five digesta samples from each proximate jejunum, distal jejunum, and mid-colon were collected from 7- and 27-day post-weaned pigs and subjected to microbiota analysis using 16S rRNA gene profiling. Taxonomic analysis at phylum level revealed that Proteobacteria was significantly higher at 7 days (13.54%), while Bacteriodetes was higher at 27 days (30.72%) post weaning. Genera such as Campylobacter, Veillonella, Helicobacter, and Blautia that were previously reported in intestinal dysbiosis were significantly enriched in seven-day post-weaned pigs. However, microbial communities shifted as post weaning age increased with a significant increase in alpha diversity, and genera such as Moryella, Dialister, Clostridium, Streptococcus, Prevotella, and Bacteroides become significantly abundant in 27-day post-weaned pigs. Interestingly, the genus Campylobacter was significantly abundant on seven-day post-weaning in two piglets with diarrhea, implicating its role in post-weaning diarrhea. The results of this study suggest that gut microbiota in pigs with dysbiosis on 7-day post weaning undergoes significant changes toward a more normal state as the post-weaning age reaches 27 days.

“…Genus Campylobacter spp. is known to play a role in the aggravation of diarrhea and thus, is relatively abundant in piglets suffering from diarrhea [ 42 , 43 ]. In addition, De Rodas et al [ 44 ] reported that Campylobacter was negatively correlated with body weight in growing pigs.…”

Sow productivity, that is, the number of weaned piglets per sow per year, depends on their health status. The gut microbiota is considered a crucial factor in the health of pigs and may affect sow productivity. In the present study, we aimed to investigate the relationship between productivity and the fecal microbiotas of sows in different farms. Feces of sows were collected from 18 farms (10 samples/farm). A total of 90 fecal samples of high-reproductive performance farms were labeled as group H, and 90 fecal samples from low-reproductive performance farms were labeled as group L. Fecal microbiotas were analyzed by 16S rRNA metagenomics, and the organic acids and putrefactive metabolites of the microbiotas were measured. β-diversity was significantly different between groups H and L (p < 0.01), and the relative abundances of 43 bacterial genera, including short-chain fatty acid-producing and fiber-degrading bacteria such as Ruminococcus, Fibrobacter and Butyricicoccus, significantly differed between groups (p < 0.05). In addition, the concentrations of acetate, propionate and n-butyrate were significantly higher in group H than in group L (p < 0.05). In conclusion, sow productivity in farms was likely associated with the compositions of the fecal microbiotas.
