The Codes of Recommendation for the Welfare of Livestock : Pigs (1991) suggest that the minimum total floor space for pigs growing to 20 kg should be 0.15 m2 per pig. This space allowance should be adequate for sleeping, feeding, dunging and exercise. However, no allowance has been made for the space the pig needs to signal submission during an aggressive interaction, and it may be that this is one of the reasons why weaning is associated with such a high level of aggression and a reduction in growth rate. The objective of this experiment was to try to reduce aggression and belly-nosing and to improve weight gain by building a hide area (using a barrier) into conventional weaner pens. The steel-framed barriers that were used took up very little space in the pens. Three trials involving 120 Large White X Landrace piglets were carried out. In each trial, piglets were weaned at 24 days and were assigned at random to one of four treatments; straw pen with a barrier, straw pen with no barrier, flatdeck cage with a barrier, flatdeck cage with no barrier, each group contained ten piglets.

The intestinal microbiota plays several important roles in pig health and growth. The aim of the current study was to characterize the changes in the fecal microbiota diversity and composition of weaned piglets following an oral challenge with an ETEC: F4 strain and/or a treatment with colistin sulfate (CS). Twenty-eight piglets were used in this experiment and were divided into four groups: challenged untreated, challenged treated, unchallenged treated, and unchallenged untreated. Rectal swab samples were collected at five sampling times throughout the study. Total genomic DNA was used to assess the fecal microbiota diversity and composition using the V4 region of the 16S rRNA gene. The relative abundance, the composition, and the community structure of piglet fecal microbiota was highly affected by the ETEC: F4 challenge throughout the experiment, while the oral treatment with CS, a narrow spectrum antibiotic, resulted in a significant decrease of E. coli/Shigella populations during the treatment period only. This study was the first to identify some gut microbiota subgroups (e.g., Streptococcus, Lachnospiraceae) that are associated with healthy piglets as compared to ETEC: F4 challenged animals. These key findings might contribute to the development of alternative strategies to reduce the use of antimicrobials in the control of post-weaning diarrhea in pigs.

AbstractThe aim of the study was to assess the effect of fermented dried soybean (FSBM) and/or fermented rapeseed meal (FRSM) in diets for weaned piglets on production results, nutrient digestibility, gastrointestinal tract histology, and the composition of the gut microbiota. Piglets in the control group received standard diets with soybean meal. Animals in all experimental groups received diets in which a portion of the soybean meal was replaced: in group FR—8% FRSM; in group FR/FS—6% FRSM and 2% FSBM; in group FS/FR—2% FRSM and 6% FSBM and in group FS—8% FSBM. The use of 8% FRSM or 6% FRSM and 2% FSBM in the piglet diets had a positive effect on average daily gains. Piglets from the FR and FR/FS groups had the highest feed conversion rate. Group FS/FR and FS piglets had significantly lower mortality and lower incidence of diarrhoea. Piglets fed a diet with the fermented components, in particular with 8% FRSM or 6% FRSM and 2% FSBM, exhibited a positive effect on the microbiological composition and histology of intestines, which resulted in improved nutrient digestibility coefficients (ATTD and AID).

Abstract Benzoic acid (BA) and essential oils (EO) can minimize growth performance losses due to the removal of antibiotics and change the intestinal health of weaned piglets. The objective of this study was to evaluate the effects of BA and EO on inflammatory response, diarrhea incidence, and growth performance of the nursery phase. One hundred and twenty barrows were weaned at 23 days (6.40 ± 0.53 kg) and assigned into 3 treatments (10 replicates) in randomized block design: basal diet without additives (NC), basal diet with 200 ppm of colistin sulphate (PC), and association of 0,3% benzoic acid and essential oil (BA+EO). The feed intake and body weight were recorded at 0 and 42 days. The feces were assessed daily (per animal) and graded as normal feces (no diarrhea) or liquid or pasty stools (presence of diarrhea). On days 1, 3, and 9, blood samples were collected (5 replicates) for white blood cells (WBC) counts. Growth performance was analyzed by MIXED procedure (SAS, 2009) and the Tukey test was used to compare the means (P < 0.050). The WBC counts were analyzed by repeated-measures analysis of variance, by MIXED procedure. Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The BA+EO treatment showed a similar body weight (P = 0.014) and average daily gain (P = 0.012) than the PC group and lower feed conversion ratio (P = 0.037) compared to the NC group. The pigs of the BA+EO treatment had the lowest diarrhea incidence during the total period (P < 0.001). The supplementation with BA+EO or antibiotics reduced the counts of total WBC (P = 0.008) and neutrophils (P = 0.003). In conclusion, supplementation with BA+EO reduces the inflammatory response and the incidence of diarrhea in the nursery phase, that may be related to the improvement in the FCR.

This study investigated the effects of dietary C. butyricum ZJU-F1 on the apparent digestibility of nutrients, intestinal barrier function, immune response, and microflora of weaned piglets, with the aim of providing a theoretical basis for the application of Clostridium butyricum as an alternative to antibiotics in weaned piglets. A total of 120 weanling piglets were randomly divided into four treatment groups, in which piglets were fed a basal diet supplemented with antibiotics (CON), Bacillus licheniformis (BL), Clostridium butyricum ZJU-F1 (CB), or Clostridium butyricum and Bacillus licheniformis (CB-BL), respectively. The results showed that CB and CB-BL treatment increased the intestinal digestibility of nutrients, decreased intestinal permeability, and increased intestinal tight junction protein and mucin expression, thus maintaining the integrity of the intestinal epithelial barrier. CB and CB-BL, as exogenous probiotics, were also found to stimulate the immune response of weaned piglets and improve the expression of antimicrobial peptides in the ileum. In addition, dietary CB and CB-BL increased the proportion of Lactobacillus. The levels of butyric acid, propionic acid, acetic acid, and total acid were significantly increased in the ceca of piglets fed CB and CB-BL. Furthermore, we validated the effects of C. butyricum ZJU-F1 on the intestinal barrier function and immune response in vitro and found C. butyricum ZJU-F1 improved intestinal function and enhanced the TLR-2-MyD88-NF-κB signaling.
