The article presents the results of a study to research the effectiveness and safety of disinfectant "Indez" as a sanitizing substance for the prevention of bacterial infections of poultry, as well as its effect on the respiratory system. In the course of the experiment, broiler chickens from 2 poultry houses were used, where each of them had 10,000 heads of Cobb crosses, which were kept by the floor method. Before and after the use of disinfectant "Indez" measurements of total bacterial contamination were carried out, including sanitary-indicative (coliform bacteria) microflora of poultry, and also studied the effect of disinfectant on the morphological and biochemical parameters of poultry blood. Blood for morphological and biochemical studies was taken in the morning before feeding, by puncture of the axillary vein on the 5th, 10th and 20th day of the experiment. Morphological parameters were determined in the blood of broiler chickens, and in the serum were determined: total protein content, protein fractions, bilirubin level, alkaline phosphatase (LF) activity, aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The investigated means "Indez" was used to rehabilitate the poultry house by uniformly sprinkling the surface where the chickens were kept at the rate of: the first sprinkling 80 g / m2, and the following - once a week 50 g / m2. In the poultry house, where the chickens of the control group were, the premises were not disinfected. Analysis of the obtained data on bacterial air pollution in both experimental poultry houses shows that after the use of the drug "Indez" the level of total bacterial contamination decreased in the poultry house № 1 in 3.35 times, including sanitary-indicative microflora in 2.83 times . In the poultry house № 2 after treatment with the test agent, the level of total bacterial contamination was - 573.3 thousand microns. cells / m3 of air, which is 1.5 times less than before treatment. At the same time, the level of coliform bacteria decreased by 1.68 times. The influence of disinfectant on the dynamics of hematological and biochemical parameters of broiler chickens is analyzed. In the study of morphological parameters of the blood of broiler chickens under the conditions of application of disinfectant "Indez" on the 20th day of the experiment in both groups of birds their hematological parameters did not differ statistically and fluctuated within the parameters of physiological norm: hemoglobin concentration (95.6 ± 0.6 and 95.4 ± 2.04 g / l, respectively), the number of erythrocytes (3.6 ± 0.24 and 3.5 ± 0.16 T / l), leukocytes (23.8 ± 0.37 and 24.2 ± 0.58 G/l). When studying the biochemical parameters of the serum of broiler chickens, it was found that the activity of the enzymes AST, ALT and alkaline phosphatase in the experimental and control groups of chickens during the experiment remained at the same level - from 233.75 ± 3.36 to 238.67 ± 1.28 U/cm3, from 17.4 ± 1.21 to 20.28 ± 1.11 U/l and from 64.2 ± 1.88 to 65.20 ± 2.18 U/l, respectively. It should be noted that the serum of control and experimental birds after remediation "Indez" during the experiment, the content of total protein and albumin, as well as the level of α-, β- and γ-globulins were at the same level with slight fluctuations within the physiological norm: 58.02±1.07– 60.74±1.17 g/l and 33.2 ± 0.65–34.38 ± 1.1%, as well as 16.44 ± 0.68–17.39 ± 0.87%, 13.3 ± 0.91–14.92 ± 0.77% and 33.7 ± 1.03–36.9 ± 0.98%, respectively. The index of total bilirubin in the serum of the control and experimental groups of chickens was also within the parameters of the physiological norm both before and after disinfection of the poultry house in the presence of poultry: from 1.87 ± 0.28 to 2.13 ± 0.22 μmol / l . The displayed results indicate that the use of disinfectant "Indez" for disinfection in the presence of birds did not cause visible clinical changes in the body. The safety of the use of the drug "Indez" in poultry houses in the presence of poultry is proved by the results of hematological and biochemical studies, as well as confirmed by the results of pathological autopsy.

In this study, structural characteristics, mechanization applications, problems and solution suggestions of poultry houses of broiler chickens in Bolu central district were investigated. The surveys were conducted in a total of 200 broilers in 8 villages (Oğulduruk, Taps, Değirmenbeli, Çivril, Banaz, Yakuplar, Vakıfgeçitveren and Çaygökpınar) where the broiler production of the central district of Bolu was intensively produced. The field work for the surveys was conducted in February-April 2018. In the broiler houses surveyed in the central district of Bolu, it was determined that the capacity was generally in the range of 5.000 ≤ Capacity < 20.000 (74%), and nearly all of the houses (96.5%) were in the east-west direction. It was determined that the concrete materials are used in the foundations of all the houses examined, and %79 Sandwich panel on the walls and 86.5% of the poultry houses are used mechanical ventilated, in 70% of the poultry houses have 9 and more fans for ventilation, and in all of the poultry house are used luminaires for illumination.It was determined that 91.5% of the poultry houses had a tractor, 96% of the poultry houses had full automatic watering, and nipple drinker with lifting system was used and 87.5% of the poultry houses had honeycomb (Ped) application. It was determined that the number of animals placed in 1 m² was 16-18 (42.5%). It was determined that 15.5% of the problem, 13% of deficiency of information with the broiler houses, 20% of credit and debt problems. Then, there should be a solution to the problem of disease among the producer problems in the enterprises examined and the credit facilities should be improved. In addition, manufacturers need to be informed according to new technological developments in information deficiencies.

Complex Drug

For disinvasion of poultry houses on this site against the exogenous stages of eimeria, a new complex drug “Delegol Pro” was used to prepare poultry houses for occupancy. The drug toltrazuril was prescribed to 2.5% of the chickens aged 8–9 days against the endogenous developmental stages of eimeria. Studies conducted after 1, 2, 3, 4 weeks after planting chickens and before slaughter, showed contamination of the litter with eimeria oocysts. The average number of oocysts in 1 g of litter during different periods of research was 3.32; 14.4; 8.6; 7.9 and 3.7 thousands, respectively. Our data show that the release of oocysts begins to decrease gradually 2 weeks after the application of toltrazuril. The low level of oocysts in the litter at the end of the broiler breeding cycle (3.7 thousands) indicates that chickens are well immune to coccidiosis. Contamination of the litter of broiler chickens with invasive elements during outdoor maintenance of the poultry houses during the technological cycle of cultivation after disinfestation and when prescribing coccidiostatics was established from July to September 2017 in the conditions of the “White Bird” Poultry Factory by taking and examining the litter samples at different times of growing broilers. To disinfect all 34 poultry houses at this site against the exogenous stages of ameri, a new complex drug “Delegol Pro” was used in a dose of 0.5 l / m2 at an exposure time of 2 hours when preparing poultry houses for settlement.

The respiratory diseases of broiler chickens are included among the very important problems in the poultry industry. The pathogenic causes of these diseases are viruses (NDV, IBV, ILTV, etc), bacteria (Mycoplasma spp, Haemophilus paragallinarum, E.coli, ORT, etc), fungi and parasites. These factors can act either alone, leading in complete disease or in combinations, causing respiratory syndromes. In broiler flocks the most frequent respiratory disease with considerable economic losses is Colibacillosis. It is either the result of primary infection of the birds with the pathogenic E.coli or secondary as complicated agent leading in the CDR syndrome. The evaluation of the respiratory diseases incidents in the Clinic of Avian Medicine showed that there has been a gradual decline in the number of the respiratory diseases during the last decade 1992 - 2001. More specifically, the percentages of the incidents of respiratory diseases were: 26,49% (1992), 22,14% (1993), 17,24% (1994), 18,00% (1995), 10,04% (1996), 9,93% (1997), 11,92% (1998), 7,79% (1999), 7,77% (2000) and 6,99% (2001). This significant reduction of the respiratory disease percentages was probably caused by factors relative with a series of measures applied in breeder flocks, in hatcheries and in poultry houses. These measures concern the continuous improvement of the poultry houses and equipment, the application of systematic vaccination programs in breeders and chicks, the good collaboration between farmers and veterinarians, the improvement of nutrition, the supplying of chicks free of bacteria, such as Mycoplasma spp, Salmonella spp, etc, and viruses, such as Reovirus, Chicken anemia virus, e.t.c, and the strict application of appropriate disinfections. The application of the above measures reduces the poultry stress, enhances their immunity, eliminates the presence and the spread of pathogens and secures better health and growth in the birds of the poultry industry.
