This study investigated the effects of Clostridium butyricum (C. butyricum) use on growth performance, serum immunity, intestinal morphology, and microbiota as an antibiotic alternative in weaned piglets. Over the course of 28 days, 120 piglets were allocated to four treatments with six replicates of five piglets each. The treatments were: CON (basal diet); AGP (basal diet supplemented with 0.075 g/kg chlortetracycline, 0.055 g/kg kitasamycin, and 0.01 g/kg virginiamycin); CBN (basal diet supplemented with normal dosage of 2.5 × 108 CFU/kg C. butyricum); and CBH (basal diet supplemented with high dosage of 2.5 × 109 CFU/kg C. butyricum). Body weight (BW) and feed consumption were recorded at the beginning and on days 14 and 28 of the experiment, and representative feed samples and fresh feces were collected from each pen between days 26 and 28. Average fecal score of diarrhea was visually assessed each morning during the experimental period. On the morning of days 14 and 28, blood samples were collected to prepare serum for immune and antioxidant parameters measurement. One male piglet close to the average group BW was selected from each replicate and was slaughtered on day 21 of the experiment. Intestinal crypt villi, and colonic microbiota and its metabolites short-chain fatty acids were measured. Compared to the CON group, the CBN and AGP groups significantly decreased (p < 0.05) the ratio of feed to weight gain by 8.86% and 8.37% between days 1 and 14, 3.96% and 13.36% between days 15 and 28, 5.47% and 11.44% between days 1 and 28. Dietary treatment with C. butyricum and AGPs significantly decreased the average fecal score during the experimental period (p < 0.05). The apparent total tract digestibility of dry matter, organic matter, and total carbohydrates in the CBH group were higher respectively at 3.27%, 2.90%, and 2.97%, than those in the CON or AGP groups (p < 0.05). Compared to the CON group, the CBH group significantly increased short-chain fatty acids in colon and villus height in the jejunum (p < 0.05). The CBN group had higher serum levels of immunoglobulins, interleukin 2 (IL-2), and glutathione peroxidase (GSH-PX) activity, but lower serum levels of IL-1β and IL-6, and a lower aspartate aminotransferase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transpeptidase (γ-GT) activity (p < 0.05), while compared to the CON group. Dietary treatment with C. butyricum significantly increased the relative abundance of Streptococcus and Bifidobacterium (p < 0.05). In summary, diet with C. butyricum increased the growth performance and benefited the health of weaned piglets.

This study was conducted to evaluate the effects of dietary FVS supplementation on growth performance, nutrient digestibility, biochemical profile of serum and fecal short chain fatty acids (SCFAs) production in weaned piglets. In Exp.1, 150 weaned pigs (initial body weight: 6.89 ± 1.17 kg) were allotted to five dietary treatments. The treatment diets included a basal diet and four experimental diets supplemented with 2.5%, 5.0%, 7.5% and 10.0% FVS respectively. The animal trial lasted for 28 days. In Exp.2, 72 piglets (initial body weight: 8.20 ± 1.67 kg) were allotted to three dietary treatments. The treatment diets included a basal diet and two experimental diets supplemented with 1.5% and 3.0% FVS, respectively. The animal trial lasted for 56 days. The results showed that pigs fed dietary FVS with 3% or lower inclusion levels had no significant difference (p > 0.10) on growth performance compared with pigs fed the control diet during day 1–28 and day 1–56. Dietary FVS supplementation decreased the apparent total tract digestibility (ATTD) of nutrients on day 28, day 35 and day 56, but no significant changes (p > 0.05) of nutrient digestibility were observed on day 14. Although piglets fed diets with higher levels of FVS showed impaired growth performance and ATTD of nutrients, dietary FVS supplementation improved the fecal SCFA production, antioxidant capacity, interleukin-2 and growth hormone levels in serum, and reduced the harmful low-density lipoprotein levels in serum on day 56. In conclusion, as a promising alternative fibrous ingredient, FVS could be supplemented in diets of weaned piglets with a proportion under 3%.

Abstract This study was conducted to determine the effects of organic and medium chain fatty acids (OMCFA) as antibiotic substitutes on growth performance, immune function, intestinal morphology, and ileum microbiota of weaned piglets challenged with Escherichia coli K88. Over 28 days, 150 weaned piglets (28-day old, 8.80 ± 0.19 kg) were allocated to five treatments (with five replicates of six piglets each): negative basal diet (NBD), positive basal diet (PBD), antibiotic growth promoters diet (AGPD, BD+0.04 g/kg zinc bacitracin, 0.03 g/kg chlortetracycline, and 0.05 g/kg kitasamycin), OMCFA 1 diet (BD+0.2% OMCFA, OMCFA is a synergistic blend of a phenolic compound, slow release C12, target release butyrates, formic, acetic, lactic, propionic, citric, sorbic acid), and OMCFA 2 diet (Day 1 to 14: BD+0.8% OMCFA, Day 15 to 28: BD+0.6% OMCFA). On the 15th day, piglets in the PBD, AGPD, OMCFA 1, and OMCFA 2 treatment groups were orally challenged with 20 mL Escherichia coli K88 (108 CFU/mL). Body weight on day 14 and average daily gain from 1st to 14th day of the subjects in the AGPD and OMCFA 1 groups were higher than those in the NBD and PBD groups (P &lt; 0.05). Diarrhea rate after challenge was lower in the AGPD group than PBD one, and there was no significant difference between the AGPD and OMCFA 1 group. OMCFA decreased total leukocytes and the percentage of neutrophils (P &lt; 0.05), increased the percentage of lymphocytes (P &lt; 0.05), on day 14, and increased villus height and villus height/crypt depth ratio in the duodenum, jejunum, and ileum, compared with PBD group. 16S rDNA sequencing showed that OMCFA might stabilize the ileum microbiota caused by E. coli K88 challenge. These results indicated that OMCFA could be used as potential alternatives to AGPs in weaned piglets.

Abstract This experiment evaluated the effect of dietary protease supplementation on pig’s growth performance and post-weaning diarrhea in a 43-d trial. A total of 936 weaned pigs [21 d of age, initial BW 5.87 ± 0.31 kg] were used in a 2 × 2 factorial design (2 nutritional levels × 2 protease levels). The nutritional levels corresponded to a standard feeding program and a reduced feeding program (15% lower SID Lys) and without or with protease supplementation (0.0125% inclusion). Piglets were distributed in 36 pens with 26 pigs per pen and 9 replicates per dietary treatment. Pigs received a common Phase 1 diet and experimental diets in Phase 2, 3, and 4, (0.91, 3.4, 4.5, and 24.0 kg/pig, respectively). Phytase was included at 2,500 U in Phase 2 – 4, all diets met energy and AA:Lys requirements for nursery pigs. Feed intake and body weight were determined every 2 weeks. A pen fecal score assessment was performed at d7, 10, and 14. Performance data were analyzed using the PROC MIXED procedure and fecal score data using the PROC FREQ procedure (SAS Inst., Inc., Cary, NC). No significant interactions (P &gt; 0.05) were observed between dietary treatments. From d15 to 43 and during overall experimental period, pigs fed standard diets had greater BW, ADG, and G:F (P &lt; 0.05) than pigs fed deficient diets (Table 1). On d7, pigs fed deficient diet had more (X2 &lt; 0.05) soft and watery feces, and consequently less normal feces compared to pigs fed standard diets (Figure 1). On d7, 10, and 14, pigs fed diets with protease supplementation had more (X2 &lt; 0.05) normal feces compared to control pigs. Overall, effects of dietary protease supplementation on growth performance were not expressive under the conditions of this study but protease addition benefited intestinal health of nursery pigs.

We aimed to investigate the effects of Clostridium butyricum-, Bacillus subtilis-, and Bacillus licheniformis-based potential probiotics on the growth performance, intestinal morphology, immune responses, and caecal short chain fatty acids (SCFAs) and microbial structure in broiler chickens. Three treatment groups containing a total of 1200 one-day-old AA broilers were included: birds fed with a basal diet only (Con), birds fed with added 1010 probiotics cfu/kg (ProL), and birds fed with added 1011 probiotics cfu/kg (ProH). The dietary probiotics significantly improved the final and average body weights and serum immunoglobulins A, M, and Y. The probiotics also enhanced the ileal morphology and improved the caecal acetate, butyrate, and propionate contents. Furthermore, 16S rRNA sequencing revealed that dietary compound probiotics modulated the caecal microflora composition as follows: (1) all birds shared 2794 observed taxonomic units; (2) treatment groups were well separated in the PCA and PCoA analysis; (3) the relative abundance of Parabacteroides, Ruminococcaceae_UCG-014, Barnesiella, Odoribacter, [Eubacterium_coprostanoligenes_group], [Ruminococcus]_torques_group, and Butyricimonas significantly varied between treatments. The compound probiotics improved the growth performance, serum immune responses, the ratio of ileal villus height to crypt depth, and major caecal SCFAs in broiler chickens. The dietary C. butyricum-, B. subtilis-, and B. licheniformis-based probiotics improved overall broiler health and would benefit the poultry industry.

Abstract Vitamin B6 (VB6), which is an essential functional substance for biosome, plays an irreplaceable role in animal health. However, there are few studies that focus on the correlation between VB6 and intestinal health in weaned piglets. This study was conducted to investigate the effects of VB6 on the growth performance, intestinal morphology, and inflammatory cytokines and amino acid (AA) transporters mRNA expression in weaned piglets that are fed a low crude-protein (CP, 18%) diet. Eighteen crossbred piglets with initial body weights of 7.03 ± 0.17 kg (means ± SEM), weaned at 21-d age, were randomly assigned three diets with 0, 4, and 7 mg/kg VB6 supplementation, respectively. The experimental period lasted 14 days. Our results showed that there were no significant differences in growth performance, diarrhea rate, and biochemical parameters among the three treatments. In the jejunum, dietary VB6 supplementation did not affect the morphology and positive Ki67 counts. Dietary supplementation with 4 mg/kg VB6 decreased the mRNA expression of COX-2, IL-10, and TGF-β (P &lt; 0.05). Dietary supplementation with 7 mg/kg VB6 increased the mRNA expression of SLC7A1, SLC7A6, SLC16A14, and SLC38A5 (P &lt; 0.05) and 4 or 7 mg/kg VB6 decreased SLC36A1 mRNA expression (P &lt; 0.05). In the ileum, VB6 supplementation did not affect positive Ki67 counts but significantly decreased villus area (P &lt; 0.05) and tended to decrease villus height (P = 0.093). Dietary supplementation with 4 mg/kg VB6 had significantly increased the mRNA expression of IL-1β, TNF-α, COX-2, IL-10, and TGF-β (P &lt; 0.05). Dietary supplementation with 4 or 7 mg/kg VB6 had significantly decreased SLC6A20, SLC7A1, SLC7A6, SLC16A14, and SLC38A5 mRNA expression (P &lt; 0.05). These findings suggest that dietary supplementation of VB6 mainly down-regulated inflammatory cytokines and up-regulated AA transporters mRNA expression in jejunum, while up-regulated (4 mg/kg) inflammatory cytokines and down-regulated AA transporters mRNA expression in ileum, which may provide a reference for the intestinal development of weaned piglets that are fed a low-CP diet.

Abstract Background: Probiotics seem to be an alternative to antibiotics for improving animal's health and intestinal development. Saccharomyces boulardii ( S. boulardii ) is a well-known probiotic. However, only few studies have been performed examining the effects of S. boulardii on weaned piglets . Therefore, this study was conducted to investigate the effects of dietary S. boulardii mafic-1701 on growth performance, antioxidant parameters, inflammation and intestinal microbiota in weaned piglets, using aureomycin as positive control. One hundred and eight piglets were randomly divided into three dietary treatment groups: (1) basal diet (CON); (2) basal diet supplemented with 75 mg/kg aureomycin (ANT); (3) basal diet supplemented with 1 × 10 8 CFU/kg S. boulardii mafic-1701 (SB). Results: Compared to CON, the supplementation with S. boulardii mafic-1701 improved feed efficiency over the entire 28 days ( P < 0.01) and decreased the rate of diarrhea during the first week ( P < 0.05). Total superoxide dismutase concentration was markedly increased in piglets with S. boulardii mafic-1701 ( P < 0.01). Moreover, compared with CON, SB increased the concentration of interleukin-4 in ileum ( P < 0.05), while the level of pro-inflammatory cytokines interleukin-6 ( P < 0.01) and tumor necrosis factor ( P < 0.01) were decreased in jejunum. SB increased the abundance of Bacillus and Ruminococcaceae ( P < 0.05), whereas the population of Clostridiaceae were decreased ( P < 0.05). Furthermore, the analysis of microbiota metabolites showed that S. boulardii mafic-1701 administration increased the concentration of formate and isobutyrate in cecum to maintain a stable microbiota and gut health ( P < 0.05). Conclusion: This study indicated that S. boulardii mafic-1701 supplementation could improve growth performance, alleviate the severity of diarrhea in weaned piglets, which may be associated with S. boulardii mafic-1701 promoted antioxidant activity, anti-inflammatory responses and microbi al ecology of piglets.

Abstract Glucan has been studied as a potential alternative to antibiotics for animals in recent years. The aim of this study was to evaluate the effect of dietary glucan on growth performance and gut health of weaning piglets, which is a water-soluble extracellular ꞵ-glucan produced by Agrobacterium sp. ZX09. A total of 108 weaned piglets (21 d of age; 6.05 ± 0.36 kg) were randomly assigned (6 pens/diet; 18 piglets/pen) to 3 dietary treatments consisting of a basal diet (control group) or the basal diet supplemented with 20 ppm olaquindox or 200 ppm glucan for 14 days, respectively. The results showed that piglets fed with glucan had greater (P &lt; 0.05) body weight and average daily gain than piglets in control group. Piglets fed with glucan or antibiotic had greater villus height to crypt depth ratio on duodenum compared with control group (P &lt; 0.05). The mRNA expression of Claudin-1 on duodenum or ileum was higher (P &lt; 0.05) in glucan group than that on the other groups. The mRNA expression of TLR4, MYD88 and NFκB on jejunum were lower (P &lt; 0.05) in glucan or antibiotic group than those in control group. Dietary supplementation with glucan tended to increase the IL-10 and SIgA concentration on ileum (0.05 &lt; P &lt; 0.1). Dietary supplementation with glucan tended to increase the total antioxidant capacity on jejunum (P = 0.093). In conclusion, 200 ppm glucan or 20 ppm olaquindox can improve the growth performance of weaning piglets. The glucan may can accelerate the growth of weaned piglets by improving gut health. This research will provide guidance for the olaquindox alternative on growing piglets.

This study was conducted to compare the effect of Colistin and Cap-Met supplementation in nursery pig diets on growth performance, fecal score, short chain fatty acids in the caecum and gut immunity. Seventy-two crossbred pigs (Duroc x Large White x Landrace; initial weight 6.76 ± 0.22 kg) were divided into 3 groups with 6 replications of 18 piglets each. There were 3 dietary treatments: 1) basal diet, 2) basal diet + Colistin 40 ppm and 3) basal diet + 0.2% Cap-Met. The supplementation of 0.2% Cap-Met improved FCR of piglets during 24-38 days of age. At 66 days of age, supplementing Colistin or Cap-Met increased the concentration of lactic acid in the caecum, while the IL-1 beta level in the jejunum declined. In conclusion, Cap-Met supplementation improved the FCR and showed positive immune and inflammatory responses of piglets.
