AbstractEnterotoxigenic Escherichia coli (ETEC) F4ac is a major constraint to the development of the pig industry, which is causing newborn and post-weaning piglets diarrhea. Previous studies proved that FaeG is the major fimbrial subunit of F4ac E. coli and efficient for bacterial adherence and receptor recognition. Here we show that the faeG deletion attenuates both the clinical symptoms of F4ac infection and the F4ac-induced intestinal mucosal damage in piglets. Antibody microarray analysis and the detection of mRNA expression using porcine neonatal jejunal IPEC-J2 cells also determined that the absence of FaeG subunit alleviated the F4ac promoted apoptosis in the intestinal epithelial cells. Thus, targeted depletion of FaeG is still beneficial for the prevention or treatment of F4ac infection.

Abstract A total of 38 mixed parity sows were used from 28-d of gestation until weaning to determine the effects of medium chain fatty acids (MCFA) in sow and nursery pig diets on litter characteristics and growth performance. On 28-d of gestation, sows were blocked by parity and body weight (BW), and allotted to either a control diet (UNSUP) or a control diet plus 0.3% inclusion of DaaFit Plus (MCFA) fed during gestation and lactation. At weaning, piglets (n=432) were allocated in a 2x2 factorial based on maternal diet (UNSUP or MCFA) and post-weaning diet (UNSUPnurs or MCFAnurs) in a 3-phase nursery pig feeding program lasting 42 days. Individual piglets were weighed at birth, 7-d, at weaning and every 2 weeks post-weaning. A flu outbreak occurred during the latter part of gestation leading to high overall stillborn rate (11%). There was no impact of MCFA supplementation on sow performance (P>0.14). During the suckling period, MCFA fed to sows had no impact on piglet weights or ADG (P>0.82). In the nursey period, overall gain (0.112±0.02 kg) was low in the first two weeks possibly due to health challenges. Supplementation of MCFA to sows or nursery pigs had no impact on body weights during the nursery period (P>0.32); however, absolute differences between groups increased with week [wean, 0.10kg; wk 2, 0.14kg; wk 4, 0.71kg; wk 6, 0.83kg) to the advantage of MCFA fed pigs. Pigs from MCFA fed sows had greater feed intake (P< 0.02) from 14 to 28-d and decreased gain:feed (P < 0.04) from 28 to 42-d compared to pigs from UNSUP sows. Overall, sow and nurser-y pigs fed MCFA had numerically greater 42-d BW, ADG, and ADFI. In conclusion, despite health challenges, supplementation with MCFA in gestation, lactation or in the nursery period improved piglet performance.

Weaning Piglets

Recently, we have proved that the early-life galactooligosaccharides (GOS) intervention could improve the colonic function by altering the bacterial composition in the suckling piglets. However, whether the early-life GOS (ELG) intervention could have a long influence of the colonic microbiota, and the ELG and post-weaning GOS (PWG) combined intervention would have an interaction effect on maintaining colonic health in weaning piglets remain to be explored. Thus in this study, we illustrated the differential effect of ELG and PWG intervention on colonic microbiota and colonic function of weaning piglets. Our results showed that both the ELG and PWG intervention decreased the diarrhea frequency of weaning piglets, while the PWG intervention increased colonic indexes. After 16S rRNA MiSeq sequencing of gut bacteria belonged to colonic niches (mucosa and digesta), the PWG increased the α-diversity of colonic mucosal bacteria was revealed. In addition, we found both the ELG and PWG intervention enriched the abundance of short chain fatty acids (SCFAs) producer in different colonic niches and increased total SCFAs concentrations in colonic digesta. These changes selectively modulated the mRNA expression of pattern recognition receptors and barrier proteins in the colonic mucosa. Of note, the combined effect of ELG and PWG effectively enhanced colonic SCFAs producer enrichment and up-regulated the butyrate concentration. Meanwhile, the gene expression of MyD88-NFκB signaling and the pro-inflammatory cytokines contents were markedly reduced under the combined effect of ELG and PWG. Importance Reducing the disorders of gut ecosystem is an effective way to relieve weaning stresses of piglets and save economic losses in the modern swine industry. To this end, prebiotics were often added in diet during the weaning transition. In present study, we demonstrated that the ELG and PWG intervention had shown different effects on the bacterial composition of different colonic niches and colonic function in the weaning piglets. Especially under the combined effect of ELG and PWG intervention, the gene expression of MyD88-NFκB signaling and the contents of pro-inflammation cytokines decreased with the increasing concentration of butyrate, which is one of the important microbial metabolites in the colon of weaning piglets. These findings further provided new insights into nutritional interventions to alleviate intestinal ecosystem dysbiosis and gut dysfunction in the piglets during the weaning transition.
