Characterization of the fecal microbiota of Pampa Rocha pigs, a genetic resource endemic to eastern Uruguay.

ABSTRACT: Pampa Rocha (PR) is a breed of pig that emerged in eastern Uruguay during the 18th century. They represent an important resource for non-intensive production using purebred or crossbred animals. However, productive activities have been oriented towards intensive production using commercial breeds, abandoning, except by some academic and educational institutions, the promotion of this creole breed. Thus, a population of few animals is still maintained, which could be in danger of disappearing. This work focuses on the fecal microbiota of these animals, which is related to the animal genetic background but also to their grazing capacity and resistance to weather. The structure and diversity of bacterial communities in the intestines of four PR adult females and of other breeds, including crosses, reared under non-grazing conditions, were analyzed and compared. Results obtained indicate that PR fecal microbiota is clearly different from those of other animals analyzed. Some sequences, corresponding to particular groups apparently related to the consumption of fiber, were strongly associated with PR pigs.

Project description:The present study was conducted to investigate the effects of early fecal microbiota transplantation on gut development in sucking piglets. A total of 24 3 day-old DLY sucking piglets (2.11 ± 0.15) kg were randomly divided into four groups (TMP, YMP, RMP and control group (CON)), which were transplanted with intact fecal microbiota of Tibetan pig (TP), Yorkshire pig (YP), Rongchang pig (RP), and without transplantation, respectively. The whole trial lasted for 56 d. The results are as follows: when compared with the YMP and RMP treatments, TMP and CON had a lower diarrhea index (P < 0.05), TMP and CON had higher GLP-2 and ANG4 mRNA abundances in the ileum (P < 0.05), and the TMP had a higher jejunal villus height: crypt depth and a higher colonic GLP-2 mRNA abundance (P < 0.05). Moreover, when compared with the YMP and RMP treatments, TMP had an enhanced DMT1 mRNA abundance in the duodenum (P < 0.05), TMP and CON had a greater lactase activity and a higher DMT1 mRNA abundance in the jejunum (P < 0.05), and CON had a higher γ-GT activity in the jejunum (P < 0.05). The jejunal Ca2+, Mg2+-ATPase activity in TMP was higher than that in CON, and the jejunal Na+, K+-ATPase activity in TMP was higher than that in the other three treatments (P < 0.05). Besides, when compared with the YMP and RMP treatments, TMP had a lower MDA content and a higher MUC1 mRNA abundance in the jejunum (P < 0.05); CON had a higher SOD activity in the jejunum (P < 0.05), whereas TMP and CON had a higher butyric acid concentration in the colon and a lower LPS content in the serum (P < 0.05). Finally, when compared with the TMP treatment, the other three treatments had an enhanced IL-10 mRNA abundance in the colon (P < 0.05), YMP and CON had higher counts of Escherichia coli in the colonic digesta (P < 0.05), and the CON had lower counts of Lactobacillus spp in the cecal and colonic digesta (P < 0.05). These data indicated that early transplantation of the fecal microbiota from the Yorkshire pigs and Rongchang pigs to DLY suckling piglets would destroy the gut microbiota balance and thus damage intestinal health.

Project description:BackgroundThe application of fecal microbiota transplantation (FMT) to improve swine growth performance has been sporadically studied. Most of these studies used a single microbiota source and thus the effect of donor characteristics on recipient pigs' fecal microbiota development and growth performance is largely unknown.ResultsIn this study, we collected feces from six donors with heavy (H) or light (L) body weight and different ages (d 42, nursery; d 96, growing; and d 170, finisher) to evaluate their effects on the growth performance and fecal microbiota development of recipient pigs. Generally, recipients that received two doses of FMT from nursery and finisher stages donor at weaning (21 ± 2 days of age) inherited the donor's growth pattern, while the pigs gavaged with grower stage material exerted a numerically greater weight gain than the control pigs regardless of donor BW. FMT from heavier donors (NH, GH, and FH) led to the recipients to have numerically increased growth compared to their lighter counterparts (NL, GL, and FL, respectively) throughout the growing and most finishing stages. This benefit could be attributed to the enrichment of ASV25 Faecalibacterium, ASV61 Faecalibacterium, ASV438 Coriobacteriaceae_unclassified, ASV144 Bulleidia, and ASV129 Oribacterium and decrease of ASV13 Escherichia during nursery stage. Fecal microbiota transplantation from growing and finishing donors influenced the microbial community significantly in recipient pigs during the nursery stage. FMT of older donors' gut microbiota expedited recipients' microbiota maturity on d 35 and 49, indicated by increased estimated microbiota ages. The age-associated bacterial taxa included ASV206 Ruminococcaceae, ASV211 Butyrivibrio, ASV416 Bacteroides, ASV2 Streptococcus, and ASV291 Veillonellaceae. The body weight differences between GL and GH pigs on d 104 were associated with the increased synthesis of the essential amino acid, lysine and methionine, mixed acid fermentation, expedited glycolysis, and sucrose/galactose degradation.ConclusionsOverall, our study provided insights into how donor age and body weight affect FMT outcomes regarding growth performance, microbiota community shifts, and lower GI tract metabolic potentials. This study also provided guidance to select qualified donors for future fecal microbiota transplantation.
