The purpose of the research is to identify species of Eimeria spp. in chicken broilers suspected to be infected with coccidia and to determine the effect of coccidiostatics in the course of coccidiosis.Materials and methods. The study involved 20 six-week-old broiler chickens obtained from a farm heavily affected by coccidia (natural infection – a high oocyst incidence). Each group yielded 10 randomly picked chickens to be used in the experiment. The birds were divided into 2 groups 10 chickens each: control (I); Baycox-treated (II); Baycox was applied for 2 days in a concentration of 25 ppm in drinking water. Samples of broiler chickens’ droppings were tested qualitatively by the flotation method (Willis-Schlaaf) and then quantitatively by the McMaster technique. The chickens were killed 6 days post-treatment and their intestinal mean total lesion scores (MTLS) were graded 0 to 4 on an arbitrary scale described by Johnson and Reid (1970).Results and discussion. As a result of the research, six species of protozoa of the genus Eimeria were identified: E. acervulina, E. tenella, E. brunetti, E. maxima, E. mivati, E. necatrix, while E. necatrix and E. maxima were the dominant species. This proves the presence of such species as E. mivati, E. acervulina (76.34%) in the anterior segment of the intestine and E. necatrix, E. maxima (83.34%) – in the middle segment of the small intestine. Infections of E. brunetti broilers amounted to 51.11%. The most pathogenic species of E. tenella residing in the cecum was found in 37.53%. MTLS in the group of chickens that received Baycox was 0.33. The post-treatment oocyst indices in the second group amounted to 1 (1–50 oocysts in 1 g of faeces), in the control group MTLS was very high (2,5), the oocyst index exceeding 3.

The aim of the present study was to investigate the efficacy of monensin sodium grain size on controlling coccidiosis in broiler chickens. Three hundred and fifty Cobb 700 chicks were infected experimentally with 8 × 10(4) sporulated oocysts of Eimeria spp. The birds were fed with diets supplemented with powdered (n = 150) or granulated (n = 150) monensin, with particle sizes of ≤100 µm and 450-650 µm, respectively. The remaining chicks (n = 50) were used as an unmedicated control group. The birds’ weights and number of oocysts per gram of litter in each group were recorded weekly. A total of 96 birds were randomly selected and culled during the trial. Their intestinal oocyst counts and lesion scores were determined. No significant differences in body weights were found between the groups at the end of the study. The percentages of infected animals, oocyst counts and lesion scores were significantly higher in the control group than in the other two groups; the two treated groups did not show any appreciable differences to each other. Enteritis was observed in 14 birds, all in the group supplemented with granulated monensin. These results suggest that powdered and granulated monensin have comparable efficacy in controlling coccidiosis in broiler chickens. However, treatments with monensin sodium of high grain size may be subject to contraindications relating to enteritis.

Production of poultry meat organized on industrial principles, i.e. in intensive way, is characterized by housing of broilers in closed buildings, often in very high housing densities with completely controlled conditions of environment and nutrition. Objective of the research was to investigate the possibility for improvement of certain slaughter traits of broiler chickens using lower housing density of 12 birds/m2 of box floor area in comparison to control group which was housed in density of 16 birds/m2. Body masses of broilers of both sexes prior to slaughtering were higher in trial group (p<0,01) 2460,91 g for male broilers, and 2063,33 g for female broilers compared to control group (2078,67 g males and 1740,0 g females). As a consequence of greater body masses prior to slaughtering in broilers of trial group also highly significantly greater (p<0,01) masses of processed carcasses were determined. Differences in relative indicators of yield of processed carcasses between investigated groups were not significant. Shared of major carcass part in broilers of both sexes were slightly higher (p>0,05) in trial group compared to control. On carcasses of investigated males in lower housing density the share of breasts was increased the most, and on female carcasses the share of drumsticks.

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.

Introduction. Professional groups of railway workers engaged in the repair of wagons are directly responsible for the safety of railway traffic. The analysis of literature testifies to insufficient attention of researchers to the hygienic problems associated with labor activity of workers of wagon-repair production.The aim of the study is to assess the occupational risk to the health of wagon repair workers, due to the impact on them of factors of the working environment and the labor process.Materials and methods. The study used comprehensive hygienic studies using the methodology of occupational risk to worker’s health.Results. The leading factors of the working environment (class of working conditions 3.2–3.4), which are exposed to workers depending on the specifics of the work performed. Identified professional groups with medium (significant) high (unbearable) and very high (intolerable) category of a priori occupational risk: in wagon meintenance workshop — 17 groups (94% of jobs), in a wagon assembly workshop — 11 groups (80% jobs), in wagon wheel workshop — 3 group (100% jobs). At the same time, according to the request for medical care, employees were diagnosed with isolated cases of occupational diseases.The levels of morbidity with temporary disability of employees of the main workshops are statistically significant (p<0.05) higher than those of the control group in 1.4–1.9 times. The influence of the complex of chemical factors of low and medium intensity on the levels of morbidity of respiratory diseases in the group of workers of the wagon wheel workshop, which were 1.7–2.0 times higher than in the control group, is confirmed by the average degree of causation of the production condition of this pathology (RR=1.7; EF=42.0%).The combined effect of vibration and severity of the labor process forms a high level of temporary disability of employees of the main workshops in connection with diseases of the musculoskeletal system, which was 2.7–4.4 times higher than in the control group, and also determines the prevalence of this pathology in the structure of diseases detected on medical examinations (23.2%). Diseases of the musculoskeletal system are caused by the production of employees of the wagon meintenance workshop (RR=3,9; EF=74,9%), as the most unfavorable in terms of hygiene on these factors.The stressful influence of the complex of harmful production factors on the health of wagon repair workers is manifested by the high risk of diseases of the cardiovascular system, gastrointestinal tract, neurological disorders, violation of adaptation of the cardiovascular system in 97% of the examined, as well as the predominance of diseases of the digestive system and circulatory system detected on periodic medical examinations.Conclusions. Harmful working conditions (class 3.1–3.4) cause the suspected occupational risk from small (moderate) to very high (intolerable) to 100% of the jobs of wagon repair workers. The results of the study of morbidity and risk of pathology indicate a significant risk of damage to the health of workers.

It is known that necessary to replace the components of organic acids, which are part of acidifiers when drinking water to poultry in order to prevent the adaptation of microbes in the gastrointestinal tract. In the poultry industry organic acids are widely used, which are used as acidifiers to preserve the properties of water consumed. The purpose of this work was to evaluate the efficiency of broiler meat production when using acidifying agents of drinking water Aquasafe and Veleguard. The experimental part of the work has been performed in JSC “Kurinoe Tsarstvo-Bryansk” broiler area “Roshcha” in the Pochepsky district. The object of research was the livestock of broiler chickens cross Cobb 500 at floor housing. The effect of water acidifiers on meat productivity has been studied. Groups of chickens have been formed on the principle of pairs-analogues. Broiler chickens of experimental groups have been separated from the main livestock by a grid in the corner of the room for 100 heads in each group. It has been found by a result of research to be optimal dose usage of acidifying agents water Aquasafe and Veleguard to drink to broiler chickens. The positive effect of these acidifiers on the digestion of crude protein, crude fat, crude fiber, contributing to the effective use of nitrogen, which led to an increase in the intensity of growth, young animals’ livability and improved feed conversion. Slaughter yield in the control group was 55,1 %, and in the experimental group 57,2 and 58,4 %, which was by 2,1 and 3,3 % higher with the same level of metabolic energy and nutrients. In chickens that consumed acidifi ers more intensively used nutrients feed for deposition in the body of the components of the carcass, which affected the production. A positive impact of acidifying agents Aquasafe and Veleguard on meat quality in broiler chickens has been found.

Introduction Increasing the immune system's function of fighting infectious diseases is very important in the poultry industry. Ginger, scientifically known as Zingiber officinale, belongs to the Zingiberaceae family. The use of ginger in the diet of poultry increases serum levels of superoxide dismutase enzymes and glutathione peroxidase, which are considered to be important antioxidant enzymes. The main objective of the present study is to evaluate the effect of ginger on the spleen tissue of broiler chickens. Material and Methods The specimens comprised 2 groups of 20 Ross breed broiler chicks, for 42 days and were then, examined and tested. The diet was supplemented with 1 g/kg of ginger powder from the beginning of the rearing period. Blood samples of the chicks were randomly collected to measure the levels of hemagglutination (HI). The removed spleens were fixed with 10% formalin buffer. The specimens were cut in 5-micron diameters and stained with hematoxylin and eosin. Results and Conclusion There was a statistically significant difference in the mean of HI blood titers between the chicks in the growth period and final period groups (p < 0.05). The white-pulp tissue samples were more clearly seen in the treatment group than in the control group, and also, it was observed that the wall of the central artery of the white pulp was thicker in the ginger-treated group as compared with the control group. The nutritional value of ginger may vary. Thus, it is necessary to investigate the effect of this plant final on weight gain; the serum factors associated with the metabolic chart, and the response of the immune system to this plant.

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.

Recovery of lower extremity (LE) function in chronic stroke patients is considered a barrier to community reintegration. An adequate training program is required to improve neural and functional performance of the affected LE in chronic stroke patients. The current study aimed to evaluate the effect of somatosensory rehabilitation on neural and functional recovery of LE in stroke patients. Thirty male and female patients were recruited and randomized to equal groups: control group (GI) and intervention group (GII). All patients were matched for age, duration of stroke, and degree of motor impairment of the affected LE. Both groups received standard program of physical therapy in addition to somatosensory rehabilitation for GII. The duration of treatment for both groups was eight consecutive weeks. Outcome measures used were Functional Independent Measure (FIM) and Quantitative Electroencephalography (QEEG), obtained pre- and post-treatment. A significant improvement was found in the FIM scores of the intervention group (GII), as compared to the control group (GI) (p < 0.001). Additionally, QEEG scores improved within the intervention group post-treatment. QEEG scores did not improve within the control group post-treatment, except for “Cz-AR”, compared to pretreatment, with no significant difference between groups. Adding somatosensory training to standard physical therapy program results in better improvement of neuromuscular control of LE function in chronic stroke patients.
