The aim of this study is to determine the efficiency of Forsythia suspense extract (FSE) as an antibiotics substitute on performance, nutrient digestibility, serum antioxidant capacity, fecal Escherichia coli concentration and intestinal morphology of weaned piglets. A total of 108 Duroc × (Landrace × Yorkshire) weaned piglets (28 days (d) weaned, average body weight of 8.68 ± 1.36 kg) were randomly assigned into three dietary treatments, six pens per treatment, three barrows and three gilts per pen. The treatments contained a corn-soybean meal basal diet (CTR), an antibiotic diet (basal diet + 75 mg/kg chlortetracycline; CTC), and an FSE diet (basal diet + 200 mg/kg FSE; FSE). The experiment included phase 1 (d 1 to 14), phase 2 (d 15 to 28) and phase 3 (d 29 to 35). Compared with CTR, piglets fed FSE show improved (p < 0.05) average daily gain (ADG) and average daily feed intake in phase 2, as well as enhanced (p < 0.05) ADG from day 15 to 35 and day 1 to 28. Piglets supplemented with CTC and FSE showed a reduced (p < 0.05) diarrhea rate in phase 1, while piglets fed FSE showed enhanced (p < 0.05) apparent total tract digestibility (ATTD) of dry matter, organic matter, crude protein and gross energy, as well as lower (p < 0.05) nitrogen output in phase 2 compared with CTR and CTC. The content in the form of Colony-Forming Units (CFUs) of fecal E. coli on day 14 and 28 was lower (p < 0.05) in piglets fed FSE in comparison with CTR. The contents of total antioxidant capacity, superoxide dismutase and catalase in serum are enhanced (p < 0.05) compared with CTR and CTC, whereas the concentration of malondialdehyde in serum was decreased (p < 0.05) for piglets fed FSE on day 28 compared with CTC. The villus height to crypt depth ratio in ileum was numerically higher (p < 0.05) in piglets fed FSE in comparison with CTR. In conclusion, dietary FSE supplementation could substitute CTC in improving antioxidant capacity, nutrients digestibility and reducing fecal E. coli content, so as to reduce nitrogen output and diarrhea rate, and eventually improve performance in weaned piglets.

This experiment was performed to examine the hypothesis that blood plasma (BP) with yeast (Saccharomyces cerevisiae) supplement in the diet of weaning pigs could provoke the growth performance, nutrient digestibility, fecal microbial, and reduce harmful gas excretion. A total of one hundred and eighty healthy piglets were taken and assigned (complete random blocks) to three dietary treatments as: Phase 1: Treatment (TRT) 1-6% BP; TRT 2-3% BP + 3% yeast; TRT 3-6% yeast. Phase 2: TRT 1-3%; BP., TRT 2-1.5% BP + 1.5% yeast; TRT 3- 3% yeast. Phase 3: TRT 1- Control (CON) (Basal diet); TRT 2- CON; TRT 3- CON for six- weeks. Each treatment had twelve replicates and five (three gilts and two barrows) pigs per pen. Dietary inclusion of BP with yeast supplementation significantly increased the body weight of piglets during phase 2 (p = 0.003) and phase 3 (p = 0.032). In addition, TRT2 group piglets had a significant improvement in average daily gain at the end of each phase and overall (p = 0.047, 0.025, 0.018 and 0.012, respectively). At phase 3, TRT2 group piglets showed a significant improvement on nutrient digestibility of dry matter (p = 0.012) and nitrogen (p = 0.040). The fecal microbiota of TRT2 group piglets showed a tendency to increase the number of Lactobacillus counts at phase 1 (p = 0.07) and phase 2 (p = 0.06) as well as, a significant improvement at phase 3 (p = 0.021). In addition, TRT2 group piglets had trend to decrease NH3 (p = 0.074) and H2S (p = 0.069) during phase 2, and significantly reduced NH3 (p = 0.038) and H2S (p = 0.046) at phase 3. However, the fecal score of piglets remains unaffected during the entire trial. At the end of phase 1 piglets’ IgG (p = 0.008) was significantly increased with the inclusion of BP with yeast supplementation. Based on the positive effects on body weight, average daily gain, nutrient digestibility, Lactobacillus count, and reduced gas emission, we suggest that dietary supplement with BP and yeast in the diet of weaned piglet could serve as an excellent alternative to antibiotics growth promoters.

Trihexanoin is a short-chain triglyceride (SCT). Many studies have reported that SCTs play important roles in the maintenance of intestinal epithelial structure and function. The present work was to investigate the effects of trihexanoin on growth performance, carbohydrate and fat metabolism, as well as intestinal morphology and function in weaned piglets. Twenty weaned piglets (21 ± 2 d) were randomly allocated to one of two treatment groups: The control group (basal diet supplemented with 0.5% soya oil); the TH group (basal diet supplemented with 0.5% trihexanoin). Dietary trihexanoin supplementation significantly reduced diarrhea rate; increased the concentrations of LDL, HDL and total protein in plasma; decreased cholesterol concentrations and glutamyl transpeptidase activity in plasma; improved intestinal morphologic structure; altered the mRNA levels and abundances of proteins related to glycogen and fat metabolism, mucosal barrier function, antioxidant capacity and water transport capacity; and altered the community of intestinal microflora. These results indicate that dietary trihexanoin supplementation could reduce diarrhea, regulate carbohydrate and fat metabolism, exert beneficial effects on the intestinal mucosal barrier, protect the intestinal mucosa from injuries, improve intestinal transport and absorption, and enhance antioxidant capacity. In conclusion, dietary supplementation with 0.5% trihexanoin improves the intestinal function and health of weaned piglets.

Abstract Background: The inclusion of high-quality proteins and the protein restriction are commonly used in swine production. Our study was conducted to evaluate the effects of hydrolyzed wheat protein (HWP), fermented soybean meal (FSBM), and enzyme-treated soybean meal (ESBM) in low-protein diets on antioxidant capacity, immunity, fecal microbiota and metabolites of weaned piglets.Methods: A total of 144 weaned piglets were randomly assigned to 3 dietary treatments with 6 replications of 8 piglets per pen. The experiment was divided into phase 1 ( days 0-14) and phase 2 (days 15-28). The dietary treatments contained 15.90% HWP, 15.80% FSBM, and 15.10% ESBM in phase 1, and 7.90% HWP, 7.80% FSBM, and 7.50% ESBM in phase 2, respectively.Results: The ADG of piglets in the ESBM group was higher (P < 0.05) than HWP and FSBM during days 1-28. Compared with HWP and FSBM, piglets in ESBM had higher (P < 0.05) serum levels of FRAP and SOD on days 14, as well as higher (P < 0.05) serum FRAP level on days 28. Piglets in ESBM had lower (P < 0.05) serum levels of DAO and IL-1β than HWP on day 28. ESBM significantly increased the abundance of Bacteroidetes, Oscillospiraceae and Christensenellaceae and decreased the Clostridiaceae abundance in the feces compared with HWP and FSBM. The PICRUSt analysis revealed that the number of gene tags involved in valine, leucine and isoleucine degradation and lysine degradation in ESBM were lower (P < 0.05) than HWP and FSBM. Piglets in ESBM had higher (P < 0.05) fecal butyrate content compared with FSBM, and ESBM tended to decrease (P = 0.076) fecal cadaverine level.Conclusions: Overall, ESBM had advantages over HWP and FSBM in improving antioxidant capacity, immunity, and fecal microbiota and metabolites of weaned 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.

A total of 150 weaning pigs (7.53 ± 1.23 kg) were randomly assigned to three treatments consisting of basal diet, and the basal diet supplemented with 300 and 600 mg kg−1 of probiotics, respectively, in a 42 d trial. The incremental levels of probiotics linearly increased average daily gain during week 1 and through the overall experimental period (P < 0.05). The average daily feed intake, body weight, and the apparent total tract digestibility of dry matter, nitrogen, and gross energy also increased (P < 0.05) with the increased level of probiotics. A significant reduction in Escherichia coli counts (P = 0.0037) and increase (P = 0.0016) in Lactobacillus counts were observed on day 42.

A total of 160 crossbred weanling pigs [(Landrace × Yorkshire) × Duroc, 28 days old] with an initial bodyweight of 8.01 ± 0.74 kg were used in a 42-day trial (Phase 1: Days 1–14, Phase 2: Days 14–42). The experiment was conducted to evaluate the effects of the inclusion of fermented oats (FO) to a corn and soybean meal-based diet on the performance of weanling pigs fed with high nutrient-density (HD) and low nutrient-density (LD) diets. Pigs were randomly distributed into one of four dietary treatments in a 2 × 2 factorial arrangement. Two levels of nutrient density [LD = 3323 (Phase 1: 1–14 days) and 3269 kcal/kg (Phase 2: 14–42 days); HD = 3446 (Phase 1: 1–14 days) and 3325 kcal/kg (Phase 2: 14–42 days), the differences in dietary energy were based on differences in the content of fish meal, animal fat, corn and FO [0%, 5% (Phase 1) or 2.5% (Phase 2)] were used according to the bodyweight and sex of pigs [8 replicate pens per treatment with 5 pigs in a pen (3 gilts and 2 barrows)]. During the overall trial period (Days 1–42), the average daily gain and gain:feed ratio of pigs fed HD and FO diets were significantly higher (P ≤ 0.05) than those of pigs fed with LD and non-fermented oats diets respectively. On Day 14, the apparent total tract digestibility of dry matter and nitrogen of the HD groups were significantly greater (P ≤ 0.05) than those of the LD groups. The apparent total tract digestibility of energy of the FO groups was significantly greater (P ≤ 0.05) than that of the non-fermented oats diet groups during the whole experimental period. Pigs fed with FO showed higher (P ≤ 0.05) ileal Lactobacillus and lower (P ≤ 0.05) Escherichia coli counts compared with those fed with the non-fermented oats diet. In conclusion, administration of FO to a LD diet demonstrated beneficial effects on the growth performance, nutrient digestibility and ileal microorganisms balance of weanling pigs.

The present study tested the hypothesis that altering the ratio of omega-6 (n-6) to omega-3 (n-3) fatty acids (FAs) in the diet will improve growth performance, nutrient digestibility and blood parameters of weaner pigs. In total, 90 crossbred weaner pigs ((Yorkshire × Landrace) × Duroc, 28 days old), with an average bodyweight (BW) of 6.53 ± 0.71 kg were used in a 6-week experiment. Pigs were blocked on the basis of BW and sex and randomly allotted to one of three dietary treatments (5 pigs per pen (2 barrows and 3 gilts); 6 pens per treatment). Treatments consisted of plant-derived n-6 and n-3 FAs (15:1, 10:1 and 5:1). The experimental period was divided into three phases: Phase 1; 28–35 days of age, Phase 2; 36- 49 days of age and Phase 3; 50–70 days of age. Supplementation of varied n-6:n-3 FA ratios in the diet of weaned pigs showed linear increases (P &lt; 0.05) in BW and average daily gain during Phases 1 and 2. The feed:gain ratios reduced linearly (P &lt; 0.05) during Phase 1 and tended to reduce (P = 0.08) during Phase 2 as the ratio of n-6:n-3 FA decreased from 15:1 to 5:1. However, the overall performance of weaners was not affected by the n-6:n-3 FA ratio. Dry matter and nitrogen (N) digestibility increased linearly (P &lt; 0.05) and energy digestibility tended (P = 0.089) to increase linearly with the reduction of n-6:n-3 FA ratio from 15:1 to 5:1 during Week 3 and, in Week 6, dry-matter digestibility increased (P &lt; 0.05) linearly, whereas energy digestibility tended to increase with a decreasing n-6:n-3 FA ratio in the diet. The high-density lipid cholesterol showed a significant (P &lt; 0.05) linear increase at Week 3 and a tendency to increase at Week 6, but no significant effects on other serum lipids were observed. The dietary n-6:n-3 FA ratio did not have a significant effect on white blood cell, lymphocyte, immunoglobulin G and tumour necrosis factor-α concentrations or faecal microbial counts. In conclusion, the reduction of n-6:n-3 FA ratio from 15:1 to 5:1 in the diet did not affect the overall performance of weaning pigs. However, it showed a positive effect on the growth performance of pigs during Phases 1 and 2.

Samples (10 by 20 by 2.5 cm) of beef carcass tissue were inoculated (104 to 105 CFU/cm2) with Escherichia coli O157: H7 that was either non–acid habituated (prepared by incubating at 15°C for 48 h in inoculated filter-sterilized composite [1:1] of hot and cold water meat decontamination runoff fluids, pH 6.05) or acid habituated (prepared in inoculated water fluids mixed with filter-sterilized 2% lactic acid [LA] runoff fluids in a proportion of 1/99 [vol/vol], pH 4.12). The inoculated surfaces were exposed to conditions simulating carcass chilling (−3°C for 10 h followed by 38 h at 1°C). Treatments applied to samples (between 0 and 10 h) during chilling included the following: (i) no spraying (NT) or spraying (for 30 s every 30 min) with (ii) water, (iii) cetylpyridinium chloride (CPC; 0.1 or 0.5%), (iv) ammonium hydroxide (AH; 0.05%), (v) lactic acid (LA; 2%), (vi) acidified sodium chlorite (ASC; 0.12%), (vii) peroxyacetic acid (PAA; 0.02%), (viii) sodium hydroxide (SH; 0.01%), or (ix) sodium hypochlorite (SC; 0.005%) solutions of 4°C. Samples were taken at 0, 10, 24, 36, and 48 h of the chilling process to determine changes in E. coli O157:H7 populations. Phase 1 tested water, SH, PAA, LA, and 0.5% CPC on meat inoculated with non–acid-habituated pathogen populations, whereas phase 2 tested water, SC, AH, ASC, LA, and 0.1% CPC on meat inoculated with acid- and non–acid-habituated populations. Reductions in non–acid-habituated E. coli O157:H7 populations from phase 1 increased in the order NT = water = SH &lt; PAA &lt; LA &lt; CPC. Reductions from phase 2 for acid-habituated cells increased in the order NT = water = SC &lt; ASC = LA = AH &lt; CPC, whereas on non–acid-habituated cells the order observed was NT = water = SC &lt; AH = ASC &lt; LA &lt; CPC. Previous acid habituation of E. coli O157:H7 inocula rendered the cells more resistant to the effects of spray chilling, especially with acid; however, the trend of reduction remained spray chilling with water = non–spray chilling &lt; spray chilling with chemical solutions.

Abstract Organic acids (OA) and phytogenic compounds have been used in pig feeding as alternatives to antibiotic growth promoters. However, few studies have evaluated the systemic effect of the combination of these additives. The aim of this study was to assess the impact of an organic acid-based feed additive (OAFA), containing a blend of OA and cinnamaldehyde, on the tissue integrity of bacterially challenged piglets. Thirty weaned piglets 21 d old were used in a 19-d trial. Pigs received a standard diet during the first 7 d and afterward were allotted to five treatments. Dietary treatments were: Control (basal diet), Escherichia coli (basal diet and challenge with E. coli), colistin (basal diet + 200 mg colistin/kg feed + challenge with E. coli), OAFA1 (basal diet + 1 kg OAFA/ton feed + challenge with E. coli), and OAFA2 (basal diet + 2 kg OAFA/ton feed + challenge with E. coli). Seven days after the beginning of the treatment, the animals were challenged with an enterotoxic strain of E. coli (K88) for pigs. Five days after the challenge, all animals were euthanized for tissue sampling for histological and oxidative stress (intestine and liver) analysis. The reduced glutathione (GSH), ferric-reducing ability potential (FRAP), and free-radical scavenging ability (ABTS) assays were used to evaluate the intestinal antioxidant defense. Lipid peroxidation and superoxide anion production were evaluated through the levels of thiobarbituric acid-reactive substances (TBARS) and nitroblue tetrazolium (NBT) reduction assay, respectively. Animals fed the OAFA (1 and 2) diets had a decrease (P &lt; 0.05) on histological changes in the intestine, liver, mesenteric lymph nodes, and spleen. Greater villus height (VH) and a higher ratio of VH to crypt depth (CD) were observed in animals of the OAFA2 group compared with the control and E. coli groups. The colistin and OAFA groups decreased (P &lt; 0.05) the number of inflammatory cells in intestinal lamina propria. OAFA2 group increased (P &lt; 0.05) intestinal cell proliferation. Colistin and OAFA2 supplementation induced a decrease (P &lt; 0.05) in the levels of TBARS in both the intestine and liver compared with the E. coli group. In addition, an increase (P &lt; 0.05) in GSH and FRAP ileal levels was observed in the OAFA2 group compared with E. coli group. These results show that the supplementation with OAFA in the diet of weaned piglets, especially at a dose of 2 kg/ton (OAFA2) protected tissues against enterotoxigenic Escherichia coli (ETEC) damage.

Natural plant extracts and probiotics has been proved as the most preferred and effective alternatives for antibiotics in animal feeding. The current study aimed to investigate the facilitating effect of tartary buckwheat flavonoids and Lactobacillus plantarum on the growth performance, nutrient digestibility, antioxidant capacity, and microbiota of weaned piglets. Fifty 35-day-old weaned piglets (7.85 ± 0.67 kg) were randomly divided into five treatments with 10 piglets per treatment. Piglets in the negative control (NC) group were fed a basal diet, and others were fed basal diets supplemented with 40 mg/kg of colistin sulfate (positive control, PC), 109 CFU/kg Lactobacillus plantarum (LP), 40 mg/kg of tartary buckwheat flavonoids (BF), and a combination of 109 CFU/kg Lactobacillus plantarum and 40 mg/kg of tartary buckwheat flavonoids (LB). Supplementation of BF increased the average daily gain of piglets in the BF group (p < 0.05). The nutrient digestibility of piglets in the NC group was lower than that in other groups, while the digestibility of gross energy, dry matter, organic matter, and phosphorus of piglets in the LB group was higher than the other four groups (p < 0.05). Compared with the NC and pC group, supplementation of Lp increased the activity of superoxide dismutase (SOD), glutathione peroxidase (GSH-px), and catalase (CAT), while the BF increased the content of IgA and IgM (p < 0.05). Supplementation of colistin sulfate decreased the alpha diversity index, including chao and observed species, while the addition of Lp or combination of Lp and BF increased the abundance of Selenomonas or Mitsuokella in fecal samples, respectively. The results indicated that supplementation of Lactobacillus plantarum can improve the antioxidant capacity, while tartary buckwheat flavones can increase the growth performance and immune ability of weaned piglets. Moreover, in combination, they promote nutrient digestibility.
