The influence of fibre inclusion and transit time regulation on the performance, health status, microbial activity and population, physico-chemical characteristics of the hindgut digesta and intestinal morphology in early weaned pigs were examined. For these experiments, wheat bran (WB) was used as fibre source and loperamide as a drug (LOP) to increase the digesta transit time. In Expt 1, a total of 128 early weaned pigs were randomly distributed in a 2 × 2 factorial combination of WB inclusion (0v.40 g/kg) and LOP administration (0v.0·07 mg/kg body weight) during 13 d. For Expt 2, a total of twenty-four piglets were allotted to three dietary treatments for 15 d with the same basal diet (control diet) as Expt 1; a diet with 80 g/kg of WB and the combination of WB and LOP. In Expt 1, LOP improved the average daily feed intake and average daily gain of the animals (P = 0·001 and 0·007, respectively). The same result was obtained when WB was combined with LOP. The WB–LOP group also showed a higher concentration of SCFA (P = 0·013), acetic acid (P = 0·004) and propionic acid (P = 0·093). On the other hand, WB inclusion reduced the organic matter and crude protein digestibility (P = 0·001) and tended to decrease the enterobacteria population (P = 0·089). In Expt 2, WB increased the butyric acid concentration (P = 0·086). We concluded that the inclusion of WB to modify the intestinal microbiota activity combined with LOP may be beneficial to animal health and performance.

Abstract BACKGROUND: The effects of inorganic trace minerals (ITM) replaced by low-dose glycine-complexed trace minerals (GCM) on growth, serum parameters, immunity, intestinal morphology, and mineral excretion in piglets were investigated. One hundred and twenty-eight weaned piglets (14.18 ± 0.33kg body weight (BW)) were randomly assigned to 4 treatments with 4 replicates, 8 piglets per replicate. Treatments consist of: (T1) basal diet + 100% inorganic trace mineral (ITM) as the control group (20 ppm Cu, 150 ppm Fe, 150 ppm Zn, and 30 ppm Mn from sulfates); (T2) basal diet + 50% ITM (Cu, Fe, Zn, and Mn from sulfates, 50% of control) + 50% organic trace minerals (OTM, Cu, Fe, Zn, and Mn from glycine complexed trace minerals (GCM), 50% of control); (T3) basis diet + 50% OTM from GCM; (T4) basal diet + 70% OTM from GCM. The feeding period lasted 28 d and was divided into 2 stages (0 to 14 d and 15 to 28 d). After feeding trial , 6 pigs per treatment were randomly selected to slaughter for sampling. RESULTS: Average daily gain, feed intake, and G:F were not affected by dietary treatments during the overall period. During the second, and the overall feeding phases, the digestibility of Zn and Fe in T3 and T4 was higher than that of T1 ( P < 0.05). The concentration of serum ferritin in T2 was significantly higher than T3 and T4. Serum immunoglobulin A concentration in the ileal mucosa of T2 was higher than that of T1 ( P < 0.05), and the higher duodenum villus height was observed in T4 compared with the rest treatments ( P < 0.05). The lowest trace mineral excretion was overserved in T3 ( P < 0.01); in addition, the urinary concentrations of Zn and Fe in T2 were lower than that in T1 ( P < 0.05). CONCLUSION: These results indicate that GCM have higher bioavailability than ITM, and that supplementation of low-dose GCM to replace full dose ITM could reduce mineral excretion without affecting performance, blood profiles, immune responses, and intestinal morphology in piglets.

Abstract Marine macroalgal derivatives such as laminarin have been considered as potential bioactive compounds in swine nutrition to improve post-weaning pig performance. However, a comprehensive understanding of the impact of these extracts on the intestinal microbiome and its subsequent influence on performance is not well characterized. Therefore, the objective of this study was to evaluate the effects of supplementing the diet of newly weaned pigs with laminarin, on animal performance and the intestinal microbiota using 16S rRNA gene sequencing. At 28 days of age, newly weaned pigs (n = 54) were assigned to one of two dietary groups: 1) basal diet and 2) basal diet + 300 ppm laminarin for a 14-day period. On day 15, nine pigs per treatment (one from each pen) were humanely euthanized and high-throughput sequencing of the V3-V4 hypervariable region of the bacterial 16S rRNA gene was performed on the Illumina MiSeq. Pigs fed the laminarin-supplemented diet had increased average daily feed intake, growth rate and body weight compared to pigs fed the control diet (P &lt; 0.05). Pigs fed the laminarin supplemented diet had reduced abundances of Enterobacteriaceae (P &lt; 0.05) compared to pigs fed the control diet. Enterobacteriaceae and Helicobacteraceae had negative relationships with average daily feed intake (ADFI), average daily gain (ADG) and butyric acid concentrations. In contrast, the beneficial Prevotellaceae were positively correlated with ADFI, ADG, total VFA, acetic, propionic, butyric and negatively correlated with isovaleric acid. Hence, supplementation with laminarin may accelerate the adoption of pigs to a post-weaning diet by promoting the proliferation of bacterial species that favourably enhance nutrient digestion and reduce the load of pathogenic bacteria impacting pig performance.

Birth is one of the most important events of animal production agriculture, as newborns are abruptly forced to adapt to environmental and nutritional disruptions that can lead to oxidative damage and delay in growth. Taurine (Tau) is an important regulator of oxidative stress and possesses growth-enhancing properties. In the present study, we investigated the effects of dietary Tau supplementation in gilts during late gestation and lactation on the growth performance of piglets by assessing intestinal morphology and barrier function, and oxidative stress status. Sixteen gilts were randomly allocated to the Con (basal diet) and Tau (basal diet with 1% Tau) groups from 75 d of gestation to weaning. Maternal dietary Tau supplementation significantly increased weaning weight and average daily gain weight in piglets. Piglets in the Tau group had higher villus height and villus height-to-crypt depth ratio (VCR), ZO-1 protein expression, and secretory immunoglobulin A (sIgA) content in the jejunum. Meanwhile, Tau bebeficial affected the milk quality of gilts, as indicated by decreased malondialdehyde (MDA) concentration and increased total superoxide dismutase (T-SOD), total antioxidative capability (T-AOC), glutathione peroxidase (GPx), and catalase (CAT) activity. Furthermore, Tau supplementation increased T-SOD activity in plasma and SOD2 protein expression in the jejunum in the piglets. In conclusion, this study provides evidence that dietary Tau supplementation to gilts improves growth performance in piglets, owing to improved intestinal morphology and barrier function, as well as inhibition of oxidative stress.

A total of 45 sows (Landrace × Yorkshire) and their litters were used in this study to evaluate the efficacy of nucleotide supplementation on reproductive performance, growth performance, fecal microflora, and blood profiles in sows and piglets. Sows were allocated to one of three treatments (15 pigs per treatment and the average parity was 4.13). Dietary treatments consisted of (1) CON: basal diet, (2) T1: CON + 0.5% nucleotides, and (3) T2: CON + 1.0% nucleotides. In this study, the average daily feed intake during lactation and back fat at weaning day was increased linearly (P < 0.05) in sows with the increase in nucleotide supplementation levels. Sows receiving increasing levels of nucleotides had linearly increased fecal Lactobacillus counts and decreased Escherichia coli counts at weaning day (P < 0.05). Linear reduction of the epinephrine, norepinephrine, and cortisol in sows was observed at weaning day, whereas superoxide dismutase was increased linearly (P < 0.05). Body weight and average daily gain in piglets were linearly (P < 0.05) increased with the increasing levels of nucleotides. Linear increase (P < 0.05) was also observed on total piglets born, live piglets, and piglet survival. The current study demonstrated the importance of nucleotides in the diets of sows to improve sow and piglet performance.

The present study investigated the effects of dietary supplementation of a seaweed extract (SWE) to sows and weaned pigs on post-weaning growth performance, intestinal morphology, intestinal microflora, volatile fatty acid concentrations and immune status of pigs at days 11 and 117 post-weaning. Gestating sows (n20) were supplemented with a SWE (0v.10·0 g/d) from day 107 of gestation until weaning (day 26). At weaning, pigs (four pigs per sow) were divided into two groups based on sow diet during lactation and supplemented with a SWE (0v.2·8 g/kg diet), resulting in four treatment groups: (1) BB (basal sows–basal pigs); (2) BS (basal sows–treated pigs); (3) SB (treated sows–basal pigs); (4) SS (treated sows–treated pigs). Pigs weaned from SWE-supplemented sows had a higher average daily gain (ADG) between days 0 and 21 (P < 0·05) post-weaning compared with pigs weaned from non-SWE-supplemented sows. Pigs offered post-weaning diets (PW) containing SWE had decreased colonicEscherichia colipopulations on day 11 (P < 0·01) and decreased colonic Enterobacteriaceae numbers on day 117 (P < 0·05). Pigs offered PW containing SWE had a greater mRNA abundance ofMUC2in the colon at day 11 post-weaning (P < 0·05) compared with pigs offered unsupplemented diets. In conclusion, these results demonstrate that SWE supplementation post-weaning provides a dietary means to improve gut health and to enhance growth performance in starter pigs. Dietary SWE supplementation increased ADG during the grower–finisher (GF) phases. However, there was no growth response to SWE inclusion in GF diets when pigs were weaned from SWE-supplemented sows.

The objective of this study was to evaluate the effect of replacing cereals and protein concentrates in a high-cereal concentrate (control) for light lambs with corn distiller’s dried grains with solubles (DDGS; 18%), dried citrus pulp (DCP; 18%), and exhausted olive cake (EOC; 8%) in a byproduct (BYP) concentrate on growth performance, digestibility, ruminal fermentation, and plasma metabolites. Two homogeneous groups of Lacaune lambs (13.8 kg ± 0.25 kg) were fed one of each concentrates and barley straw ad libitum until reaching about 26 kg body weight. There were no differences between groups on feed intake, average daily gain, or feed conversion ratio, but the control diet had greater (p < 0.001) dry matter digestibility. Diet had no effect on post-mortem ruminal pH and total volatile fatty acid concentrations and profile, but NH3-N concentrations were lower (p = 0.003) for the BYP-fed group compared with the control one. However, plasma concentrations of amino acids, total proteins, urea, and hepatic enzymes were not affected by the diet. In conclusion, 44% of feed ingredients in the concentrate for light lambs can be replaced with a mixture of corn DDGS, DCP, and EOC without negatively affecting growing performance and animal health.

Gut inflammatory bowel diseases (IBDs) links to animal medicinal feed and antibiotic-resistance are fueling major economic impacts in the agricultural livestock industry. New animal feeds that promote livestock gut health and control of IBDs without antibiotics are needed. This study investigates the effects of mesobiliverdin IXα (MBV)-enriched microalgae spirulina extracts on the growth performance, blood parameters, intestinal morphology, and gut microbiota of broilers. A total of 288 1-day-old broiler chicks (Arbor Acres) were randomly allotted to six dietary treatments (4 pens/treatment and 12 birds/pen). The dietary treatments comprised a basal diet as control (CON), basal diet plus 0.05 and 0.1% microalgae extract as low and high dose, respectively (SP1 and SP2), basal diet plus 0.05 and 0.1% MBV-enriched microalgae extract as low and high dose, respectively (MBV-SP1 and MBV-SP2), and basal diet plus 0.1% amoxicillin (AMX). All treated animals showed no significant differences in live weight, average daily gain, and feed efficiency compared to control animals. Histological examination showed that AMX treatment decreased the villi lengths of the duodenum and ileum below control villi length (P &lt; 0.05) while MBV-SP1 and particularly MBV-SP2 increased villi lengths in the duodenum, jejunum, and ileum above AMX -treatment lengths (P &lt; 0.05). The Firmicutes/Bacteroidetes ratio increased in the cecum of broilers fed AMX (P &lt; 0.05) while SP2, MBV-SP1, and MBV-SP2-fed animals showed (in order) increasing ratios up to the AMX level. The abundance of bacterial species of the genus Lactobacillus increased in MBV-SP1 and MBV-SP2-fed groups including a striking increase in Lactobacillus salivarius abundance with MBV-SP2 (P &lt; 0.05). Feeding MBV-SP1 and MBV-SP2 decreased the level of pro-inflammatory cytokine IL-6 in plasma of broilers to a greater extent than SP1 and SP2. These results reveal that MBV-enriched microalgae extracts improve the intestinal health and beneficial microflora composition of broilers.

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.

Abstract Plant extracts contain active molecules called pronutrients that could replace antibiotic growth promoters (AGP) in order to improve intestinal integrity, optimize feed utilization and consequently, increase productive performance. The purpose of this study was to evaluate the effect of a mixture of pronutrients on hematological parameters, serum cytokins regulation, intestinal morphology, organs weight and productive parameters. The trial was conducted with 480 one-day-old male broilers of the Ross AP 308 divided into 3 groups: Group CON - Basal diet only, Group AB supplemented with bacitracin methylene disalicylate and Halquinol continuously, and Group PR with a mixture powder of pronutrients, respectively. The experiment lasted up to the 35th day of age. 3 % of crude soybean was added to all basal diets as a challenge for intestinal integrity. All data were statistically analyzed using ANOVA and P value less than 0.05 was set as statistically significant and 0.05 &lt; P &lt; 0.1 as tendency. A decrease of all serum cytokines (IL-1β, IL-6, IL-8, IL-10) in supplemented broilers with pronutrients was observed. The intestinal morphology parameters were better (length and villi depth) and performance parameters such as feed intake, body weight and feed conversion rate (FCR) throughout the trial were improved in broilers supplemented with pronutrients (P &lt; 0.05). Dietary supplementation with a natural additive based on pronutrients demonstrated to be an effective alternative to AGP to improve intestinal morphology, productive performance and regulating hematological and immune values in broilers challenged with diets containing raw soybean.
