In this study, the effects of (Mentha pulegium L.) dietary supplementation on performance, carcass characteristics, some biochemical parameters, and intestinal histology were investigated in broiler chickens. Four groups were formed as control and groups treated with pennyroyal at different levels (0.25%, 0.50%, and 1.00%). In the experiment. Each group had eight replicates. A total of 192 broilers were used in the study with six broilers in each replicate. Water and feed were ad libitum provided. Adding different levels of pennyroyals to broiler rations significantly affected performance parameters; an increase in final body weight and carcass yield and a decrease in total feed intake and the conversion rate was observed (P<0.05). Serum cholesterol, malondialdehyde, and glutathione values were also affected by the addition of pennyroyal (P<0.05). Pennyroyal was effective in vitro against S. enteritidis, E. coli, S. aureus, S. abortus ovis, B.anthracis sterne strains. Besides, it increased the duodenum villus’ length compared to the control group (P<0.05). On the other hand, pennyroyal did not affect carcass and visceral organ weights, several serum biochemical values (P>0.05). As a result, it was concluded that pennyroyal at the level of 0.50% in ration was effective on health and growth performance of broilers.

Abstract The problem of using high-energy diets for early maturing bird crosses is insufficient enrichment of diets, both qualitative and quantitative, with microelements. The aim of the study was to study the effect of different levels of metabolic energy (ME) of diet on productivity and morpho-biochemical parameters of broiler chickens of the Arbor Aсres cross. 3 groups with different content of ME were formed (n = 30). The control group contained 12.61 MJ / kg DM, treatment I - 13.3 MJ / kg DM, treatment II - 14.7 MJ / kg DM. So, live weight of broilers from the II experimental group was higher by 59.9% after the third week of the registration period relative to the control group, and by 18.8% (P ≤ 0.001) compared with I experimental group. At the end of registration period, broilers of II group were superior to the control and I experimental groups by 27.2% and 17.5% (p≤0.01), respectively. At the same time, in the group with the maximum OE content (group II), the level of leukocytes decreased by 9.2%, and the amount of hemoglobin increased by 6.6% compared to the control. By the end of the experiment (35 days), the activity of serum transamylases decreases in experimental groups I and II: ALT activity by 39.2% and 16.7% (P ≤ 0.05); AST by 3.8% and 1.9%, respectively, compared with the control. Thus, the content of main macronutrients of blood serum in animals with the maximum level of MA of the diet (group II) decreases: Fe by 4.95%, Mg by 3.42%, P by 16.7% (P ≤ 0.05) relative to control. Thus, an increase in metabolic energy in the diet of broiler chickens has a positive effect on productivity, causing a decrease in the content of macronutrients in blood serum. The research was carried out with financial support from RSF (20-16-00078).

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Background: Quercus serrata Murray leaves have been used traditionally in the treatment of diabetes, dysmenorrhoea, inflammation and urinary tract infection. So, far no study had been reported on the toxicological profile and antioxidant properties of the plant. Objective: The present study was aimed to investigate the in-vivo toxicological profile and in-vitro antioxidant activities of the methanolic extract of standardized Quercus serrata leaves. Methods: Per-oral sub-acute toxicity study was performed in rats using three dose levels (200, 400 and 800 mg/kg b.w.) of the extract for 28-days. Control group received gum acacia suspended in water. Bodyweight was measured weekly. Biochemical parameters were analysed using the serum, the blood-cell count was done using whole blood. Pathological changes were also checked in highly perfused tissues. Further, in-vitro reducing power assay, nitric oxide scavenging assay, DPPH free-radical scavenging assay were performed to check the antioxidant activity of the extract. Results: There were no significant alterations in the blood-cell count and biochemical parameters analysed in the treatment group when compared with the normal control. Histopathology study of liver, kidney, pancreas, heart and brain revealed normal cellular architecture in the treatment groups alike the control group animals. Quercus serrata also showed a significant reduction of DPPH with IC50 4.48±0.254 µg/mL, in-vitro reducing power activity with IC50121.65±0.320 µg/mL and nitric oxide scavenging activity IC50 106.43±0.338 µg/mL. Conclusion: The above study showed that standardized methanolic extract of Quercus serrata leaves was safe after subacute oral administration in rats and has good antioxidant potential.

The use of intensive selection procedure in modern broiler chicken lines has led to the development of several skeletal disorders in broiler chickens. Therefore, current research is focused on methods to improve the bone quality in birds. In ovo technology, using nanoparticles with a high specificity to bones, is a potential approach. The present study aimed to evaluate the effect of in ovo inoculation (IOI) of calcium carbonate nanoparticles (CCN) on chicken embryo development, health status, bone characteristics, and on broiler production results and bone quality. After assessing in vitro cell viability, the IOI procedure was performed with an injection of 500 μg/mL CCN. The control group was not inoculated with CCN. Hatchability, weight, and selected bone and serum parameters were measured in embryos. Part of hatchlings were reared under standard conditions until 42 days, and production results, meat quality, and bone quality of broilers were determined. CCN did not show cytotoxicity to cells and chicken embryo and positively influenced bone parameters of the embryos and of broilers later (calcification) without negatively affecting the production results. Thus, the IOI of CCN could modify the molecular responses at the stage of embryogenesis, resulting in better mineralization, and could provide a sustained effect, thereby improving bone quality in adult birds.

Background and Aim: Probiotics improve intestinal balance through bacterial antagonism and competitive exclusion. This study aimed to investigate the in vitro antimicrobial activity, as well as the in vivo preventive, immunological, productive, and histopathological modifications produced by probiotic Bacillus subtilis. Materials and Methods: The in vitro antimicrobial activities of B. subtilis (5×106 CFU/g; 0.5, 1.0*, 1.5, and 2.0 g/L) were tested against Escherichia coli O157: H7, Salmonella Typhimurium, Candida albicans, and Trichophyton mentagrophytes after exposure times of 0.25, 0.5, 1, and 2 h using minimal inhibitory concentration procedures. A total of 320 1-day-old female Ross broiler chickens were divided into five groups. Four out of the five groups were supplemented with 0.5, 1.0*, 1.5, and 2.0 g/L probiotic B. subtilis from the age of 1 day old. Supplemented 14-day-old broiler chickens were challenged with only E. coli O157: H7 (4.5×1012 CFU/mL) and S. Typhimurium (1.2×107 CFU/mL). A total of 2461 samples (256 microbial-probiotic mixtures, 315 sera, 315 duodenal swabs, and 1575 organs) were collected. Results: The in vitro results revealed highly significant (p<0.001) killing rates at all-time points in 2.0 g/L B. subtilis: 99.9%, 90.0%, 95.6%, and 98.8% against E. coli, S. Typhimurium, C. albicans, and T. mentagrophytes, respectively. Broilers supplemented with 1.5 and 2.0 g/L B. subtilis revealed highly significant increases (p<0.01) in body weights, weight gains, carcass weights, edible organs' weights, immune organs' weights, biochemical profile, and immunoglobulin concentrations, as well as highly significant declines (p<0.01) in total bacterial, Enterobacteriaceae, and Salmonella counts. Histopathological photomicrographs revealed pronounced improvements and near-normal pictures of the livers and hearts of broilers with lymphoid hyperplasia in the bursa of Fabricius, thymus, and spleen after supplementation with 2.0 g/L B. subtilis. Conclusion: The studies revealed that 1.5-2.0 g of probiotic B. subtilis at a concentration of 5×106 CFU/g/L water was able to improve performance, enhance immunity, and tissue architecture, and produce direct antimicrobial actions.

Abstract Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background Sevoflurane with its antiinflammatory properties has shown to decrease mortality in animal models of sepsis. However, the underlying mechanism of its beneficial effect in this inflammatory scenario remains poorly understood. Macrophages play an important role in the early stage of sepsis as they are tasked with eliminating invading microbes and also attracting other immune cells by the release of proinflammatory cytokines such as interleukin-1β, interleukin-6, and tumor necrosis factor-α. Thus, the authors hypothesized that sevoflurane mitigates the proinflammatory response of macrophages, while maintaining their bactericidal properties. Methods Murine bone marrow–derived macrophages were stimulated in vitro with lipopolysaccharide in the presence and absence of 2% sevoflurane. Expression of cytokines and inducible NO synthase as well as uptake of fluorescently labeled Escherichia coli (E. coli) were measured. The in vivo endotoxemia model consisted of an intraperitoneal lipopolysaccharide injection after anesthesia with either ketamine and xylazine or 4% sevoflurane. Male mice (n = 6 per group) were observed for a total of 20 h. During the last 30 min fluorescently labeled E. coli were intraperitoneally injected. Peritoneal cells were extracted by peritoneal lavage and inducible NO synthase expression as well as E. coli uptake by peritoneal macrophages was determined using flow cytometry. Results In vitro, sevoflurane enhanced lipopolysaccharide-induced inducible NO synthase expression after 8 h by 466% and increased macrophage uptake of fluorescently labeled E. coli by 70% compared with vehicle-treated controls. Inhibiting inducible NO synthase expression pharmacologically abolished this increase in bacteria uptake. In vivo, inducible NO synthase expression was increased by 669% and phagocytosis of E. coli by 49% compared with the control group. Conclusions Sevoflurane enhances phagocytosis of bacteria by lipopolysaccharide-challenged macrophages in vitro and in vivo via an inducible NO synthase–dependent mechanism. Thus, sevoflurane potentiates bactericidal and antiinflammatory host-defense mechanisms in endotoxemia.

Red blood cell (RBC) filtration in platelet rich plasma (PRP) and platelet poor plasma (PPP) was equally decreased (p < 0.0001) in 120 patients with acute myocardial infarction (AMI) as compared to a control group. In a double-blind experiment 2 groups of 30 patients with AMI received an acute oral dose of 60 mg of ketanserin, a serotonin (5-HT) antagonist at 5-HT2-receptors, or placebo. Ketanserin treatment improved RBC filtration in PRP with an average increase of 30%. A similar experiment using PPP showed a significant increase of 10%. Filtration of plasma improved after ketanserin treatment in PRP, but not in PPP. Cross-exchange experiments showed the ketanserin-induced improvement of RBC filtration in PRP and PPP to be also plasmadependent. 5-HT in vitro at 10−9M deteriorated RBC filtration in PPP (p < 0.05), and ketanserin in vitro at 10−7M counteracted this phenomenon (p < 0.001). Finally we found that the effect of a subacute treatment with ketanserin on the filtration of RBC Suspensions, enriched with a constant amount of white blood cells (WBC), was more pronounced than on control RBC suspensions of patients with AMI.These results indicate that the impaired RBC filtration, reported in vascular diseases may be dependent on a subtle interaction between platelets, WBC, RBC and plasma. Treatment with ketanserin is capable to interrupt this vicious circle of rheological disturbances at different levels, first of all, by improving RBC deformability, but also by counteracting the platelet mediated effects on RBC and by favourably influencing the physical properties of WBC and so preventing clogging phenomena. Serotonin probably plays a pivotal role in these cascade of events and therapy with ketanserin might be of clinical value in diseases where microcirculatory flow is compromised.

Abstract The presented investigations were conducted on a group of 60 porkers of crossbreed Polish Landrace x Large White Polish. The animals were divided into two equal experimental groups. The control group (K) was fed diets without supplementation with probiotics, group (P) - diets with the addition of probiotic (0.2 kg t-1 feed). The aim of the study was to determine the effect of probiotic preparation on total numberof lactic acid rods from the Lactobacillus genus and those forming hydrogen oxide. The second part of experiment concerned the influence of probiotic preparation on the number, haemolytic ability and changes in drug resistance of Escherichia coli isolated from animal faeces. The significantly highest number of Lactobacillus sp. were determined in the saliva of porkers fed diets with the addition of probiotic, while the lowest in the control group. Lactobacillus sp. rods capable of forming hydrogen peroxide were isolated from 17 animals in group K and from three animals in group P. E. coli was determined in each examined sample of faeces. In groups K and P, counts of these bacteria were similar and did not differ statistically. High numbers of haemolytic isolates (haemolysis β) were found in faeces of animals fed diets with the addition of probiotic. Number and proportions of resistant isolates in groups K and P were different. Gentamicin was characterised by exceptionally high in vitro effectiveness. The used probiotic increased drug resistance of E. coli and increased frequency of incidence of haemolysis β.
