The present review evaluates and compares the effects achieved after application of rabbit-derived bacteriocin-producing strain Enterococcus faecium CCM7420 with probiotic properties and its bacteriocin Ent7420. The experiments included varying duration of application (14 and 21 days), form of application (fresh culture and lyophilized form), combination with herbal extract and application of the partially purified enterocin—Ent7420, produced by this strain. Results from these studies showed that E. faecium CCM7420 strain was able to colonize the gastrointestinal tract (caecum) of rabbits (in the range < 1.0–6.7 log cycle, respectively 3.66 log cycle on average), to change the composition of intestinal microbiota (increased lactic acid bacteria, reduced counts of coliforms, clostridia and staphylococci), to modulate the immunity (significant increase of phagocytic activity), morphometry (enlargement absorption surface in jejunum, higher villi height:crypt depth (VH:CD) ratio), physiological (serum biochemistry; altered total proteins, glucose and triglycerides levels) and parasitological (Eimeria sp. oocysts) parameters and to improve weight gains (in the range 4.8–22.0%, respectively 11.2% on average), feed conversion ratio and meat quality (physicochemical traits and mineral content).

ABSTRACTIn broiler chickens, feed additives, including prebiotics, are widely used to improve gut health and to stimulate performance. Xylo-oligosaccharides (XOS) are hydrolytic degradation products of arabinoxylans that can be fermented by the gut microbiota. In the current study, we aimed to analyze the prebiotic properties of XOS when added to the broiler diet. Administration of XOS to chickens, in addition to a wheat-rye-based diet, significantly improved the feed conversion ratio. XOS significantly increased villus length in the ileum. It also significantly increased numbers of lactobacilli in the colon andClostridiumcluster XIVa in the ceca. Moreover, the number of gene copies encoding the key bacterial enzyme for butyrate production, butyryl-coenzyme A (butyryl-CoA):acetate CoA transferase, was significantly increased in the ceca of chickens administered XOS. In this group of chickens, at the species level,Lactobacillus crispatusandAnaerostipes butyraticuswere significantly increased in abundance in the colon and cecum, respectively.In vitrofermentation of XOS revealed cross-feeding betweenL. crispatusandA. butyraticus. Lactate, produced byL. crispatusduring XOS fermentation, was utilized by the butyrate-producingAnaerostipesspecies. These data show the beneficial effects of XOS on broiler performance when added to the feed, which potentially can be explained by stimulation of butyrate-producing bacteria through cross-feeding of lactate and subsequent effects of butyrate on gastrointestinal function.

Abstract The effect of Enterococcus faecium CCM7420 (EF) - enterocin-producing and probiotic strain of rabbit origin, Eleutherococcus senticosus extract (ES) and their combination (ES+EF) was determined on selected bacteria in faeces and caecum content, leukocytes phagocytosis, blood biochemistry and growth performance. Ninety-six weaned rabbits were divided into 3 experimental (ES, EF, ES+EF) and control group (CG). The rabbits in the groups ES and EF+ES were fed commercial diet enriched with E. senticosus extract (30 g/100 kg feed), rabbits in groups EF and CG were fed untreated diet. The rabbits in the EF and ES+EF groups were administered with an overnight culture of E. faecium CCM7420 strain (500 μl/animal/day into water, 109 CFU/ml). The treatment period lasted 21 days. The microbiological examinations in faecal samples confirmed the presence of E. faecium CCM7420 strain. In groups EF and ES+EF, the reduction of faecal coliforms, Pseudomonas-like sp., Clostridium-like sp. and S. aureus was recorded. Leucocyte phagocytosis significantly increased in all experimental groups (P<0.0001) compared to CG. The lowest GPx values were measured in the ES+EF group. Higher total protein, triglycerides and calcium concentrations were detected in experimental groups compared to CG. The cholesterol concentration decreased in the ES group. The highest average daily gain was recorded in EF group; in ES+EF the better feed conversion ratio and no mortality was recorded. These results indicated that the dietary supplementation with the E. faecium CCM7420 and E. senticosus extract stimulate the leukocytes phagocytosis and reduces the potential pathogens in rabbits digestive tract without oxidative stress and improve the growth performance.

Irritable bowel syndrome (IBS) is a functional bowel disorder and the etiology is not well understood. Currently there is no cure for IBS and no existing medication induces symptom relief in all patients. IBS-20 is a 20-herb Chinese medicinal formula that offers beneficial effects in patients with IBS; however, the underlying mechanisms are largely unknown. This study showed that IBS-20 potently inhibited LPS- or IFNΓ-stimulated expression of pro-inflammatory cytokines, as well as classically activated macrophage marker nitric oxide synthase 2. Similarly, IBS-20 or the component herbCoptis chinensisdecreased LPS-stimulated pro-inflammatory cytokine secretion from JAWS II dendritic cells. IBS-20 or the component herbs also blocked or attenuated the IFNΓ-induced drop in transepithelial electric resistance, an index of permeability, in fully differentiated Caco-2 monolayer. Finally, the up-regulation of key inflammatory cytokines in inflamed colon from TNBS-treated mice was suppressed significantly by orally administrated IBS-20, including IFNΓ and IL-12p40. These data indicate that the anti-inflammatory activities of IBS-20 may contribute to the beneficial effects of the herbal extract in patients with IBS, providing a potential mechanism of action for IBS-20. In addition, IBS-20 may be a potential therapeutic agent against other Th1-dominant gut pathologies such as inflammatory bowel disease.

The aim of this study was to assess the effect of low environmental temperature on growth, feed conversion, performance and selected biochemical and haematological indicators in broiler chickens. The decrease in air temperature since the 22nd day of growth influenced significantly (p < 0.05) the level of total proteins, uric acid, phosphorus (in female broiler chickens), glucose (in male broiler chickens), haemoglobin (in female broiler chickens) and liver weight (in male broiler chickens). The temperature influenced significantly (p < 0.01) the level of triiodothyronine, haemoglobin (in male broiler chickens), haematocrit, abdominal fat content (in male broiler chickens), and heart weight too. The results have clearly confirmed that during growth, the decrease in environmental temperature (cold stress) negatively influenced some indices of performance and blood system in broiler chickens.

This study was conducted in the Poultry farm of the animal during the Production department, Iraqi during the (Ministry of Science and Technology) period from 3-9-2001 to 8-4-2002. The objectives of this study were to evaluate the effect of low – level chronic aflatoxicosis on performance (body weight, feed conversion efficiency and mortality), Serum biochemistry and activity of some enzymes (GOT,GPT, ALKP, LDH). A total of 300 male chicks of broiler breeder (Faw–Bro) were used. Chicks at day 1 of age were fed diets contaminated with aflatoxine at levels of 0, 0.3, 0.6, 0.9, 1.2, and 1.5 the feeding period were extended to 8 weeks. The data were subjected to analysis of variance by the completely randomized design. The results showed the presence of a number of fungi especially the type of Aspergillus flavus genus that reaches 40%. All aflatoxine dose levels significantly (P < 0.05) decreased live weight, it was also noticed that there were higher significant decrease in feed conversion when aflatoxine level was elevated in the feed. Increasing mortality with each increasing in aflatoxine level, the low level of chronic aflatoxine in the diets caused increased in the relative weight of internal organs (Liver, Pancreases, spleen, heart, gizzard, fibresia gland) as a results of aflatoxine presence in the diet, the low level of chronic aflatoxicosis for long time decreased in packed cell volume percentage, heamoglbulin concentration and red blood cell cont., with increase in white blood cells and (neutrophil, Hetrophil, Lymphocyte). The aflatoxine increased the serum concentration of protein, albumin, Cholesterol, Phosphor the activity of LDH, GOT, GPT, AIKP.

The Impact

The exploration of feed mycotoxin adsorbents to mitigate the adverse effects of mycotoxins on animals has received increasing attention over the last decade. The present study was conducted to assess the efficacy of nano-composite magnetic graphene oxide with chitosan (MGO-CTS) adsorbents against feed contaminated with ~20 ng/g (ppb) aflatoxin (AF). A total of three hundred 1-day-old chicks were randomly distributed into six dietary treatment groups, as follows: basal diet (broilers fed a diet with neither AF nor MGO-CTS added, T1), basal diet + 0.25% MGO-CTS (T2), basal diet + 0.50% MGO-CTS (T3), AF diet + 0.25% MGO-CTS (T4), AF diet + 0.50% MGO-CTS (T5), and AF diet (T6). The two inclusion levels (0.25 and 0.50%) of MGO-CTS significantly (p < 0.05) improved the growth performances and feed conversion ratios of the AF-treated chicks at 1–35 days of age, and the impact was more pronounced for 0.5% MGO-CTS. The AF intake markedly increased the relative weights of the liver and kidney, resulting in significant alterations in the serum biochemical parameters, such as albumins, alkaline phosphatase, and SGPT/alanine (ALT), at 35 days of age. However, the chickens fed 0.5% MGO-CTS with AF diets had apparent recovery or restoration of AF-induced organ lesions and aberrant serum profiles. A significant (p < 0.05) reduction in the total AFs was observed in the gastrointestinal tracts of the chickens fed 0.25% or 0.50% adsorbent in combination with AF feed (T4 and T5), with decreases of 28.9% and 53.5%, respectively, compared with that in the chickens fed an AF-contaminated diet (T6). The results of the study indicated that a higher concentration of MGO-CTS (0.50%) was effective in improving the overall performance of broiler chickens by preventing the adverse effects associated with aflatoxicosis.

Percent Mortality

Numerous plants are reported to have ethno-therapeutic properties; among these plants are the leaves of Moringa oleifera and Azadirachta indica used for the treatment of protozoan infections. Forty grower rabbits at approximately 70 days old were used to determine the prophylactic anti-trypanosomal effects of the dry leaf meals of Moringa oleifera (MLM) and Azadirachta indica (NLM). The rabbits were placed into eight groups of five animals each in a completely randomized design, with mean live weights of 1.2 Kg. The rabbits were allotted to four diets (D1, D2, D3 and D4) and two levels of inoculation (inoculated and uninoculated rabbits) in a 4×2 factorial arrangement of a Completely Randomised Design. Parameters monitored were performance, serum biochemistry and rectal temperature. The parasitaemia were presented as line graph for the infected rabbits. The percent mortality of the groups was evaluated and no mortality was observed for rabbits fed D4. No significant differences (P>0.05) were observed between treatments for growth rate, feed intake and feed conversion, except rectal temperature and total protein (P<0.05) in serum biochemistry. Rabbits that were uninfected with trypanosomes had (P<0.05) lower total protein than the infected animals except T2. It was concluded that only the 1% MLM had prophylactic anti- trypanosomal effect on serum total protein and mortality amelioration of T. b. brucei infected rabbits when administered alone and a combination of both MLM and NLM prevented  pyrexia and mortality.     De nombreuses plantes auraient des propriétés ethno-thérapeutiques ; parmi ces plantes figurent les feuilles de Moringaoleifera et d'Azadirachtaindica utilisées pour le traitement des infections protozoaires. Quarante lapins de culture à environ 70 jours ont été employés pour déterminer les effets anti-trypanosomal prophylactiques des repas secs de feuille de Moringaoleifera (le 'MLM') et d'Azadirachtaindica (le 'NLM'). Les lapins ont été placés en huit groupes de cinq animaux chacun dans une conception complètement randomisée, avec des poids vivants moyen de 1,2 kg. Les lapins ont été attribués à quatre régimes (D1, D2, D3 et D4) et deux niveaux d'inoculation (lapins inoculés et non ininoculés) dans un arrangement factorial de 4×2 d'un Désigne complètement randomisé. Les paramètres surveillés étaient la performance, la biochimie sérique et la température rectale. La parasitémie a été présentée comme graphique linéaire pour les lapins infectés. La mortalité en pourcentage des groupes a été évaluée et aucune mortalité n'a été observée chez les lapins nourris au D4. Aucune différence significative (P>0,05) n'a été observée entre les traitements pour le taux de croissance, l'apport alimentaire et la conversion des aliments pour animaux, à l'exception de la température rectale et de la protéine totale (P<0,05) dans la biochimie sérique. Les lapins qui n'étaient pas infectés par les trypanosomes avaient (P<0,05) moins de protéines totales que les animaux infectés, à l'exception du T2. On l'a conclu que seulement le MLM de 1% a eu l'effet anti-trypanosomal prophylactique sur la protéine totale de sérum et l'amélioration de mortalité des lapins infectés de T.b. brucei une fois administrés seuls et une combinaison de MLM et de NLM a empêché la pyrexie et la mortalité.

A trial was conducted with 175 day old Ross broiler chicks to evaluate the effectiveness of Alisma canaliculatum (Water plantain or Theksa), Laminaria japonica (Sea tangle or Dashima) and Cornus officinalis (Cornelain cherry or Sansuyu) medicinal plants treated with probiotics in replacing antibiotic. Three medicinal plants were prepared in dry and flour form with treatment of probiotics. The groups were control (basal diet), antibiotic (basal diet + 0.05% OTC, oxytetracycline), Water plantain treated with Probiotics (WPP) 0.5%, Sea tangle treated with Probiotics (STP) 0.5% and Cornelian cherry treated with Probiotics (CCP) 0.5% in basal diet. The broilers were distributed in a completely randomized design having 5 replications with 7 chicks per replication in wire cage. The data were analyzed by SAS package program. Addition of three medicinal plants in broiler diets didn’t show negative effect on growth and feed conversion efficiency in broilers. Significantly highest protein percentage in broiler meat was found in groups fed the three medicinal plants treated with probiotics (WPP, STP and CCP) compared with other groups (P<0.05). Crude ash also increased significantly by the three medicinal plants addition compared to control especially in breast meat (P<0.05). Addition of probiotics treated with medicinal plants had similar beneficial effects on most of the observed parameters to those found in antibiotic-fed groups, so it implies that these three medicinal plants can be the possible alternatives to antibiotic for broiler production.Asian J.

The aim of the study was to investigate the effect of Bacillus licheniformis and salinomycin supplementation in broiler diets as individual factors or in combination on the growth performance, GIT morphometry, and microbiota populations. Four hundred one-day-old Ross 308 chicks were randomly distributed to four dietary treatments (10 replicates, 10 birds each). The following treatments were applied: NC—no additives; NC + SAL—salinomycin addition (60 mg/kg diet), NC + PRO—B. licheniformis DSM 28710 preparation (1.6 × 109 CFU/kg; 500 mg/kg diet), and NC + SAL + PRO—combination of salinomycin and B. licheniformis. Probiotic administration resulted in improvement (p < 0.05) of the performance parameters, including body weight gain (1–10 d, and 11–22 d) and feed conversion ratio (11–22 d, 1–36 d). An interaction (p < 0.05) between experimental factors was observed in terms of lower pH values in the crop (tendency, p = 0.053) and ceca. Both factors lowered the alpha diversity and Enterobacteriaceae and promoted Bacillaceae communities in the jejunum (p < 0.05). Interactions were also observed in terms of reducing Clostridiaceae in the ceca. In conclusion, the combined use of B. licheniformis and salinomycin in broilers’ diets had beneficial effects.
