Background: Neonatal and early post-weaned piglet mortality causes huge economic losses to the farmers. The beneficial effect of probiotic and zinc in respect to the gut health in piglets has already been established. Therefore, this study was aimed to evaluate age-related changes and the effect of dietary inclusion of probiotic and zinc on morphological and morphometrical characteristics on villi and crypts of the small intestine in pre and post-weaned piglets.Methods: A total of 18 Large White Yorkshire piglets, irrespective of sex were divided into three different age-groups [pre-weaning (20 days old, n = 3) and, post-weaning (30 days old, n = 3) and (60 days old, n = 3)]. The piglets were weaned at 28 days of age. They were divided into control group (C) fed with basal diet and treatment group (T) fed with combined probiotic and zinc oral supplement along with the basal diet. After sacrifice the animals, tissue samples were collected and processed for routine stain and SEM. The alterations on morphology and morphometry of villi and crypts were recorded both in the control and treatment group of piglets. Result: The villus height and width and crypt depth and width were increased, however, the villus crypt ratio was found to be lower in the treatment group of piglets. The villus and crypt enlargement factor showing higher numerical values in the piglets fed with probiotic and zinc than the control group of piglets. Scanning electron microscopy revealed a clear extrusion zone with prominent shedding of cells in the villi of jejunum and ileum in the treatment group of piglets at day 30 and 60.

Background: The present study was designed to evaluate alterations in the immunological status of the small intestine after dietary inclusion of probiotic and zinc in pre and post-weaned piglets. Methods: For the present study, 18 healthy Large White Yorkshire (LWY) piglets, irrespective of sex, were divided into three different age groups [pre-weaning (20 days old, n = 3), weaning (30 days old, n = 3) and post-weaning (60 days old, n = 3)]. The piglets were weaned at 28 days of age. They were divided into control group (C) fed with basal diet and treatment group (T) fed with combined probiotic and zinc oral supplement along with the basal diet. A probiotic mixture consisted of Lactobacillus acidophilus, Lactobacillus rhamnosus and Bifidobacterium longum (1.25x109cfu/d for 10 days) along with zinc supplement (ZnO @ 2000 ppm/d for 10 days) administered orally to the treatment group of piglets. Result: The relative expression of TNF-α, IL-1β and IL-6 genes was significantly higher (P less than 0.05) in the treatment group of piglets as compared to the control group. However, the expression of IL-8, IL-12p40 and IL-18 genes were significantly lower (P less than 0.05) after oral administration of probiotic and zinc to the piglets.

This study was conducted to investigate the effects of dietary supplementation with different types of Bacillus subtilis (B. subtilis) on the growth and gut health of weaned piglets. A total of 160 piglets were randomly assigned into four groups: control group (a basal diet), BS-A group (a basal diet supplemented with B. subtilis A at 1 × 106 CFU/g feed), BS-B group (a basal diet supplemented with B. subtilis B at 1 × 106 CFU/g feed), and BS-C group (a basal diet supplemented with B. subtilis C at 1 × 106 CFU/g feed). All groups had five replicates with eight piglets per replicate. On days 7, 21, and 42 of the trial, blood plasma and intestinal tissues and digesta samples were collected to determine plasma cytokine concentrations, intestinal morphology, gut microbiota community and metabolic activity, and the expression of genes related to gut physiology and metabolism. The results showed that dietary B. subtilis supplementation improved (P < 0.05) the body weight and average daily gain (in BS-B and BS-C groups) of weaned piglets and decreased (P < 0.05) the diarrhea rates (in BS-A, BS-B, and BS-C groups). In the intestinal morphology analysis, B. subtilis supplementation improved (P < 0.05) the size of villus height and villus height to crypt depth ratio in the ileum of weaned piglets. Firmicutes, Bacteroidetes, and Tenericutes were the most dominant microflora in piglets' colon whatever the trial group and time of analysis. Dietary BS-C supplementation increased (P < 0.05) the relative abundances of Anaerovibrio and Bulleidia and decreased (P < 0.05) the relative abundances of Clostridium and Coprococcus compared with the control group. In addition, dietary B. subtilis supplementation increased (P < 0.05) the indicators of intestinal health, including plasma levels of interleukin (IL)-2 and IL-10, as well as the colonic levels of short-chain fatty acids. Furthermore, dietary B. subtilis supplementation also up-regulated (P < 0.05) the expression of genes involved in metabolic pathways related to intestinal microbiota maturation. In conclusion, these findings suggest that a diet containing BS-B or BS-C can efficiently promote growth performance, decrease diarrhea incidence, and ameliorate several indicators of intestinal health through the modulation of gut microbiota composition and metabolic activity in 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 < 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 < 0.05). The mRNA expression of Claudin-1 on duodenum or ileum was higher (P < 0.05) in glucan group than that on the other groups. The mRNA expression of TLR4, MYD88 and NFκB on jejunum were lower (P < 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 < P < 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.

AbstractThe present study was conducted to investigate effects of Bacillus subtilis on growth performance, serum parameters, digestive enzymes, intestinal morphology, and colonic microbiota in piglets. A total of 72 piglets were weighed and randomly allotted into three treatments (four replication pens per treatment with six piglets/pen) for a 28-day experiment. The dietary treatments were as follows: basal diet (control group, CTR), basal diet supplementation with antibiotic (antibiotic group, ABT), and basal diet supplementation with 0.1% Bacillus subtilis (probiotic group, PBT). The average daily gain of body weight increased in both the ABT and PBT groups, and dietary antibiotics decreased the feed:gain ratio (F:G), as compared to the CTR group (P < 0.05). Both ABT and PBT piglets had increased serum triglycerides and lipase, amylase, maltase activities and villus height:crypt depth ratio (V/C) in ileum (P < 0.05). The PBT group also showed an increase in serum glucose and villus height in the ileum (P < 0.05). Dietary antibiotics increased Lactobacillus johnsonii, as compared to the CTR group, but decreased bacterial diversity and increased Escherichia coli, as compared to the PBT group (P < 0.05). Piglets dietary with B. subtilis modulated the microbiota by increasing the abundance of Firmicutes (L. johnsonii, L. reuteri) and decreasing the abundance of E. coli, as compared to the control group (P < 0.05). These results indicate that dietary of B. subtilis improves growth performance and intestinal health and can be a promising alternative to antibiotics in piglets diet.

The purpose of this study was to examine the effects of dietary inclusion of two additives at the final concentration of 0.5% bilberry (E1) and 1% walnut (E2) leaves powder in the basal diet on digestive health of hens. A total number of 90 Tetra SL hens were divided into two experimental groups (E1 and E2) and one control group (C) consisting of 30 hens each. After four weeks, 10 hens of each group were sacrificed and tissue samples and intestinal content were taken from the duodenum, jejunum, and cecum in order to perform histological, enzymatic, and microbiota analyses. In groups E1 and E2, the histological analysis showed a significant increase of villus height, resulting probably in increased absorption of nutrients in duodenum and jejunum. A decrease in the specific activity of alpha-amylase and trypsin in E1 and E2 for both duodenum and jejunum compared to the control one was also recorded. In addition, the maltase and invertase specific activity in duodenum increased, a tendency that was kept for maltase but not for invertase in jejunum. The cecal microbiota of E1 and E2 individuals was characterized by an increase of Firmicutes and Lactobacilli and a decrease of Enterobacteriaceae. In conclusion, our results indicate that bilberry and walnut leaves additives in feed may improve the health status of the poultry gastrointestinal tract.

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.

Forty female chickens were allocated to four groups of ten birds each. The control group (K) was fed a basal diet without supplementation. The second control group received a basal diet with humic acid (HA) at a dose of 0.5 g per chicken/day. The first experimental group was fed the basal diet with methyl-mercury (MeHg) at a dose of 0.02 mg per chicken/day and the group of chickens MeHg + HA received 0.5 g HA per chicken/day. After slaughter, mercury levels were assessed in liver, kidney, brain and muscle tissue samples. After 10-day treatment of the chickens with MeHg, significantly increased (<I>P</I> < 0.001) Hg concentrations were detected in all examined tissues in comparison with the groups K and HA. The average concentrations in liver, kidneys, brain and muscle tissues were 424, 398, 81.6 and 79.2 µg Hg/kg, respectively. After concurrent treatment with HA and MeHg, Hg concentrations were lower by 20.6%, 23.8%, 23.0% and 18.6% in liver, kidneys, brain and muscle tissues (<I>P</I> < 0.001). Biological accumulation of Hg was 25.5% and 20.4% in MeHg and MeHg + HA groups, respectively.

Abstract The effects of natural clinoptilolite (NCLI) and modified clinoptilolite (MCLI) were evaluated in broilers challenged with lipopolysaccharide (LPS) in a 21-d feeding trial. A total of 288 one-day-old chickens were allocated into three treatment groups: control, NCLI (2%) and MCLI (2%). Half of the birds from each treatment group were challenged with either 0.9% NaCl solution or LPS (250 μg/kg body weight, orally administered) at 16, 18 and 21 d of age. Before the LPS challenge, no dietary effect on bird growth performance was found (P>0.05). When LPS was orally administered, no significant changes in growth performance of broilers was found (P>0.05). However, small intestinal morphology and development, malondialdehyde (MDA) content of the jejunual and ileal mucosa, and superoxide dismutase (SOD) activity of the ileal mucosa were significantly affected (P<0.05). Supplementation with NCLI and MCLI significantly decreased the MDA contents of the jejunual and ileal mucosa and improved the SOD activity of the ileal mucosa and the development of the small intestine compared with the control group (P<0.05). The results indicated that NCLI and MCLI additions in feed had protective effects on the gut health of broilers against LPS challenge.

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.

Due to the impact of adverse environmental factors, unsatisfactory conditions of pig population, deterioration of food supply, abuse of antibiotics, lack of preventive measures, leads to the development of diseases among pigs, especially young, which leads to a decrease in resistance, body performance, reproduction and reduction of livestock, as well as large economic losses. The use of bacterial preparations from living microorganisms can significantly reduce or even eliminate the use of antibiotics and hormones in the cultivation of healthy animals, to obtain high-quality and safe high-grade products. The aim of the work is to study the effect of probiotic EM – 1 on the physiological state and productivity of young pigs of large white breed. The experiment was conducted on two groups (6 heads each) of animals-analogues, starting from 60 days of age, for 2 months. Animals of the control group received feed produced in the farm. Piglets of the experimental group in addition to the main diet received 5% of feed fermented with em-1. Evaluation of the physiological state and productivity of young pigs was carried out on 60, 90 and 120 days of experience according to the methods adopted in clinical practice. Hygienic, hematological, biochemical, zootechnical and statistical methods of research were used in the performance of the work. The use of probiotic EM-1 in animals of the experimental group led to an increase in hemoglobine concentration by 7.7%, an increase in the number of red blood cells by 13.7%, the total number of leukocytes by 9.52%, and glucose concentration by 11.4%. The advantage of the viability of these pigs for the content of total protein (P < 0.05), γ–globulins by 18.6%, the activity of aminotransferases (AlАT, AsAT; P < 0.05), the average daily gain increased by 12.3% at the end of the experiment. For feeding piglets feed with probiotic EM-1 increased metabolic processes, resistance and productivity of the body, which indicates a higher level of redox reactions in their body.
