The purpose of the research is developing a method for disinfection of environmental objects against coccidia oocysts in broiler chickens.Materials and methods. At the VNIIP – FSC VIEV vivarium, a bioassay test was performed to experimentally infect 60 chickens aged 14 days which were divided into six equivalent groups of 10 birds each and kept isolated in cages. Chickens from the first, second and third groups were administered orally, using a micropipette, 1 ml of an Eimeria oocyst suspension treated with 4, 5 and 6% solutions of the combined eimeriocide agent. Chickens from the fourth group were administered 1 ml of Eimeria oocyst suspension treated with 4% phenol solution (base drug). Chickens from the fifth group received 1 ml of a buffered solution and were used as a noninfected control. Chickens from the sixth group received 1 ml of suspension containing 2000 oocysts/mL and were used as an infected control. The efficacy of disinfection with eimeriocide and the basic drug was determined based on the percentage of decrease in the recovery of Eimeria oocysts after being exposed to drugs as compared to chickens of the infected control. The efficacy of 5% eimeriocide against poultry coccidia oocysts in a production test was determined empirically with the set of oocysts on control sites as compared with the basic drug on a poultry farm in the Moscow Region.Results and discussion. The intense-effectiveness of 4% eimeriocide against coccidia oocysts was 99.31%, and the 5 and 6% combined agent showed 100% efficacy. The basic drug, 4% phenol showed 74.65% intense-effectiveness. The results obtained in the production test of 5% eimeriocide at a dose of 0.5 l per 1 m2 with a 2 hour-exposure indicate its high efficacy for disinfection against coccidia oocysts in broiler chickens. The intense-effectiveness was 97.25% versus 59.03% efficacy of the base drug, phenol.

The purpose of the research is efficacy evaluation of the anticoccidial drug Solycox combined with the feed additive Chiktonik against avian eimeriosis.Materials and methods. The experiments were carried out on the Makhachkalinskaya poultry farm, which was contaminated with eimeriosis, on healthy 1 day old Ross-308 broilers. Two groups were formed from the selected chickens, test and control, 50 birds each. From the first day of life, broiler chickens from the test group were administered Solycox at a dose of 2 ml per 1 liter of drinking water combined with the feed additive Chiktonik at the rate of 1 ml per 1 liter of drinking water. The control chickens were not prescribed any anticoccidial drug or feed additive.Results and discussion. We established high efficacy of Solycox combined with Chiktonik against eimeriosis of broiler chickens (96%). Solycox combined with Chiktonik contributes to the poultry viability and resistance to the disease, and has a positive effect on productivity. The results of the studies allow us to recommend Solycox and Chiktonik to prevent and treat eimeriosis of broiler chickens.

The practice of successful poultry farms shows that the prevention of poultry parasitoses includes a complex of therapeutic and prophylactic measures aimed both against exogenous oocysts in the environment and against endogenous stages of the pathogen inside the bird's body with the use of modern antiparasitic drugs. In view of the foregoing and special resistance of Eimeria oocysts in the environment, it is possible to create an effective disinfectant against them using several active ingredients and excipients. Among these drugs, we should note glutaraldehyde, crystalline iodine and potassium iodide when used together at optimal concentrations. The experiments were carried out from August to October 2019 in the laboratory and vivarium of the Institute on 60 14-day-old Cobb-500 broiler chickens. Working solutions of Cystodez-ultra in different concentrations were prepared in advance, as well as a buffer solution WSH for preserving bird feces. Cystodez-ultra is a complex drug in a liquid form for disinfection of veterinary supervision objects and prevention of invasive diseases of birds. In the test, the chickens of the first, second and third groups were administered 1 ml of a suspension of Eimeria spp. oocysts treated with 3, 4 and 5% solutions of Cystodez-ultra orally using a micropipette; the fourth group was also administered 1 ml of a suspension of Eimeria oocysts treated with Phenol solution 4%. Broilers of the fifth group were administered a suspension with sporulated Eimeria spp. oocysts at a dose of 2000 per 1 ml not treated with a disinfectant - the infected control, and the sixth group 1 ml of WSH buffer solution - non-infected control. During the experiment, the chickens were followed up daily paying attention to their general condition, behavior, appetite, and visible physiological changes. According to the study results, the intense-effectiveness of Cystodez-ultra in 3, 4 and 5% concentration against sporulated Eimeria oocysts was 93.08, 100 and 100%, respectively, and Phenol in 4% concentration 76.92%. The number of oocysts in 1g of feces in the infected control was 4680 specimens, and the chickens of the uninfected control remained free from the invasion at all times of the study.

The objective of this study was to evaluate the effects of the dietary supplementation of Bacillus subtilis DSM 32315 (probiotic) on the performance and intestinal microbiota of broiler chickens infected with Clostridium perfringens (CP). One-day-old broiler chickens were assigned to 3 treatments with 8 replicate pens (50 birds/pen). The treatments were: non-infected control; infected control; and infected supplemented with probiotic (1 × 106 CFU/g of feed). On day of hatch, all birds were sprayed with a coccidia vaccine based on the manufacturer recommended dosage. On d 18–20 the infected birds were inoculated with CP via feed. Necrotic enteritis (NE) lesion score was performed on d 21. Digestive tract of 2 birds/pen was collected on d 21 to analyze the ileal and cecal microbiota by 16S rRNA sequencing. Performance was evaluated on d 28 and 42. On d 21, probiotic supplementation reduced (p < 0.001) the severity of NE related lesion versus infected control birds. On d 28, feed efficiency was improved (p < 0.001) in birds supplemented with probiotic versus infected control birds. On d 42, body weight gain (BW gain) and feed conversion ratio (FCR) were improved (p < 0.001) in probiotic supplemented birds versus infected control birds. The diversity, composition and predictive function of the intestinal microbial digesta changed with the infection but the supplementation of probiotic reduced these variations. Therefore, dietary supplementation of Bacillus subtilis DSM 32315 was beneficial in attenuating the negative effects of CP challenge on the performance and intestinal microbiota of broilers chickens.

Poultry farming, providing replenishment of the food basket with high-quality and inexpensive products, plays an important role in the formation of food security in Russia. Veterinary and sanitary examination of poultry products in the context of the ecological component of the safety of agricultural raw materials is an important and timely task within the framework of government documents of the Russian Federation in the field of health protection of the country's population. According to the results of the physical, chemical and microbiological tests of chilled broiler chicken carcasses of the 1st grade of the Ural processors («Ravis – Sosnovskaya poultry farm», «Argayashskaya poultry farm», «Nagaybak poultry complex»), the raw materials were recognized as fresh, in terms of the amount of pesticides, antibiotics and heavy metals – safe. The content of protein, fat and moisture in all studied samples corresponded to the average values. A detailed study of the mineral composition revealed negative deviations in the amount of Fe and Se in all carcass samples. The products of the Argayash poultry farm against the background of analogous samples contained less fat and moisture with identical protein values, occupied an intermediate position in the amount of essential elements – Ca, Fe, Na, P, Zn, was distinguished by the absence of minerals that increase the toxic load on the human body – Ni, Ti , Ba, Ga, Li, which formed its competitive advantages.

The study of the use of compound feed with shelled and unshelled sunflower seeds in the rearing of broiler chickens is of scientific and practical interest. The purpose of the research was to assess the influence of the inclusion of sunflower kernels and seeds in compound feed on the productivity of broiler chickens. In accordance with the set purpose and objectives of the research the experiment has been carried out on broiler chickens of the Arbor Acres cross from the daily age to the 35-day age under the conditions of the LLC “Morozovskaya Poultry Farm”. For the experiment, 5 groups of broiler chickens with 100 heads in each have been formed. The planting density, light and temperature conditions corresponded to the recommendations for growing broilers of this cross. The broilers of the control group have been received the main diet, and the poultry of the experimental groups have been received compound feed with kernels (5,0–7,5 %) and seeds (5,0–7,5 % + the enzyme drug Ronozyme VP 250 g/t) of sunflower. The results of studies on the inclusion of sunflower kernels and seeds in the diets of broiler chickens have been presented in the article. Data on zootechnical indicators of rearing, results of slaughter and anatomical cutting of carcasses, as well as economic indicators of meat production have been presented. The livability of broiler chickens both in the control and in the experimental groups was at a high level and did not depend on the inclusion of the tested ingredients in the compound feed. It has been found that the inclusion of both 5–7,5 % of sunflower kernels and 5–7,5 % of sunflower seeds with husk in the diet of broiler chickens in combination with the enzyme preparation Ronozyme (250 g/t) contributes to increasing the productivity of poultry, reducing the cost of compound feed, which allows increasing the level of profitability of meat production by 1,9–3,2 %.

ABSTRACTImproved understanding of the ecology and epidemiology ofCampylobacterin the poultry farm environment is key to developing appropriate farm-based strategies for preventing flock colonization. The sources ofCampylobactercausing broiler flock colonization were investigated on one poultry farm and its environment, from which samples were obtained on three occasions during each of 15 crop cycles. The farm was adjacent to a dairy farm, with which there was a shared concreted area and secondary entrance. There was considerable variation in theCampylobacterstatus of flocks at the various sampling times, at median ages of 20, 26, and 35 days, with 3 of the 15 flocks remaining negative at slaughter. Campylobacters were recoverable from various locations around the farm, even while the flock wasCampylobacternegative, but the degree of environmental contamination increased substantially once the flock was positive. Molecular typing showed that strains from house surroundings and the dairy farm were similar to those subsequently detected in the flock and that several strains intermittently persisted through multiple crop cycles. The longitudinal nature of the study suggested that bovine fecalCampylobacterstrains, initially recovered from the dairy yard, may subsequently colonize poultry. One such strain, despite being repeatedly recovered from the dairy areas, failed to colonize the concomitant flock during later crop cycles. The possibility of host adaptation of this strain was investigated with 16-day-old chickens experimentally exposed to this strain naturally present in, or spiked into, bovine feces. Although the birds became colonized by this infection model, the strain may preferentially infect cattle. The presence ofCampylobactergenotypes in the external environment of the poultry farm, prior to their detection in broiler chickens, confirms the horizontal transmission of these bacteria into the flock and highlights the risk from multispecies farms.

Incubation factors have a great influence on embryonic and postnatal development of broiler chickens. The aim of changing of incubation factors is to obtain the best possible production characteristics of broilers. In previous studies, it was determined that the application of monochromatic green light and thermal conditioning during incubation give the most satisfactory results on the postnatal development of chickens. This paper examines the effects of green monochromatic light and thermal conditioning during incubation on the carcass characteristics of broilers. In this paper four experimental groups were set. The first group was incubated under the standard conditions (37.8 ? C, no light). In the second group incubation temperature were increased, while in the third group incubation was carried out under green monochromatic light. In the fourth group temperature and light conditions of incubation were changed simultaneously. In all groups, changes of incubation factors were made at precisely defined time intervals. After hatching, chickens were grown up to day 42, when they were sacrificed and their carcass characteristics examined. Analysis of results showed that all treated groups have significant higher body weight, weight of drumsticks, thighs and toes. The fourth group have significant higher weight of breasts and wings compared to control group. These results are explained by the influence of the temperature and light changes during incubation on the increased proliferation of myoblasts, the growth of skeletal muscle cells, and the activity of satellite cells, which are reflected in changes of carcass characteristics.

A total of 200 one-day-old male broilers were assigned to five groups, and each group consisted of four replicates with 10 birds per replicate. Chicks were fed the basal diet with 0 (non-infected control), 0 (infected control), 10, 20, and 40 mg/kg soybean isoflavones (SI) for 42 days. At 21 days of age, chickens were inoculated with an infectious bursal dose (causing 50% morbidity) of the infectious bursal disease virus (IBDV) BC 6/85 strain by the eye-drop and nasal route (except for the non-infected group). Average daily gain (ADG) and average daily feed intake (ADFI) decreased (p < 0.05) in broilers infected with infectious bursal disease virus (IBDV) from 22 to 42 days. However, infected broilers fed 10 and 20 mg SI/kg had the maximum (p <0.05) ADG and ADFI from 1 to 42 days. Body weight (BW) increased (p < 0.05) in infected broilers fed the 10 and 20 mg SI /kg diet. The bursa weight at 7 days post-infection (dpi) was increased (p < 0.05) by the supplemental 10 mg SI/kg diet. Infected broilers showed the highest (p < 0.05) bursa lesions, with an average score of 4.0 ± 0.0, while the severity of bursa lesions was decreased (p < 0.05) at 3 dpi and 7 dpi by the supplemental 20 mg SI/kg diet. Supplemental SI at 20 mg/kg decreased (p < 0.05) the viral protein 5 (VP5) mRNA expression at 3 dpi and 7 dpi. The level of interferon gamma (IFNγ) was elevated (p < 0.05) in the infected group at 3 dpi and 7 dpi as compared with the control group, while its level was decreased (p < 0.05) by supplemental 10 mg/kg SI at 3 dpi. The level of nuclear factor κB in the bursal tissue showed the lowest value (p < 0.05) with supplemental 10 and 20 mg SI/kg diet at 7 dpi. Supplemental 10, 20, 40 mg/kg SI improved (p < 0.05) the serum total antioxidant activity (T-AOC) in infected broilers at 3 dpi. In addition, the serum level of malondialdehyde (MDA) decreased (p < 0.05) in the group fed 20 mg/kg SI at 7 dpi. In conclusion, supplemental 10~20 mg/kg SI may have a positive effect on broiler chickens infected with IBDV, probably because SI decrease the severity of bursa lesions and viral protein 5 mRNA expression, and have strong antioxidant activity.
