The aim was to determine the conversion of alimentary substances of laying hens (nitrogen, phosphorus, potassium) into the production of eggs and to determine the emission of nitrogen, air pollution by dust and microorganisms in accordance with different technologies of layer rearing. The studies were conducted in 6 poultry houses. The birds were kept in premises in cage batteries BKN-3, “Spech”, OBN-1, OBN-3 or on littered floor. It was found out that there was 1.6 times more dust in the air of poultry house where laying hens were kept on litter and the total number of bacteria was 2.4 times higher than in the bird cages (P < 0.001). The laying hens assimilated 21.95–28.42% of nitrogen, 19.63–31.25% of phosphorus, 6.04–8.33% of potassium for egg production and weight gains when feed is balanced. If cage technologies are applied, over a year, there is a loss of 6.7 ± 1.4% of nitrogen through the excrements because of nitrogen emission. When the technologies of littered floor are used, there is a loss of 18.5 ± 4.8% of nitrogen extricated with the excrements (P < 0.025). When the birds were kept in cages, 0.059 ± 0.011 kg of nitrogen per each bird evaporated because of ammonia emission, while in the case of littered floor – 0.227 ± 0.126 kg of nitrogen.

Effective modes and technology of aerosol disinfection of objects of veterinary supervision by preparation Abaldez were developed as the results of the tests. It was established that in poultry houses for growing young stock hens and keeping laying hens during the application the aerosols of 8% solution of the preparation Abaldez in the dose of 30 ml/m3 and exposure 6 hours all surfaces (wall, floor, cage, feeding bowl, drinking bowl), contaminated with intestinal sticks and staphylococci, completely disinfected, which indicates the high efficiency of the Based on the results of the researches was developed and approved «Technology of aerosol disinfection of objects of veterinary supervision by preparation «Abaldez» (approved by RAS 15.11.2016) for veterinary practice.

Before And After

Creating an optimal microclimate in poultry houses is an important condition for implementing the genetic potential of poultry productivity and minimizing the specific costs of material and technical resources. Such microclimate parameters as the content of harmful gases in the air of the poultry houses and its microbial contamination have a significant impact not only on the survival and productive parameters of the poultry, but also on the health of the staff, and the ventilation emissions from the poultry houses - on the environment. Therefore, the development of techniques and technological methods aimed at reducing the content of these ‘harmful factors’ in the air of the poultry houses is of paramount importance for modern poultry farming. The first experiments were carried out in two similar industrial poultry houses for egg laying hens, 18×96 m in size. Hens were kept in 4-tier Hellmann cage batteries with a belt removal system and integrated air ducts. The capacity of each poultry house was 47,280 laying hens. The purpose of the experiment was to study the influence of the device for the neutralization of microorganisms in the air of the poultry house and its mode of operation on the microbial contamination of the air of the poultry house and the productive parameters of the poultry. The poultry of the Lohmann Brown crossbreed was used. The next experiment was carried out in the same poultry houses as in the previous one. The purpose of the experiment was to study the effects of the application of the method of purifying the air of the poultry house from the ammonia in the scrubber on the contents of this gas in the air of the poultry house and the productive parameters of the poultry. The poultry of the Lohmann Brown crossbreed was used in the experiments. It was established that at application of a bactericidal device with 24 bactericidal tubes TUV-75 caused a decrease of microbial contamination of the air, which positively influenced the survival and productive parameters of the poultry. After 210 days of the productive period, the poultry’s survival in the experimental poultry house was higher by 0.8%; 1.3 pcs. of eggs more per one egg laying hen were obtained in this poultry house; and the egg mass was higher by 0.7 g than in the control poultry house. With the hens from the experimental poultry house, a greater bactericidal and lysozyme activity of the blood serum was observed than with the ones from the control poultry house at the age of 30 and 47 weeks. Some advantage of the poultry from the experimental poultry house was determined by the absolute mass of individual internal organs, but this advantage was not statistically probable. It was proved that in the cold season, the scrubber provided a decrease in the ammonia content in the air (when comparing the air before and after the scrubber) by 3.2-2.2 times, in the poultry house (when compared with the control) - by 2.1-1.5 times. It was established that in the experimental poultry house the poultry’s survival was greater by 0.7%, 1.6 pcs. or by 1.0% eggs more per one egg laying hen were obtained and egg mass was higher by 212 g, or by 2.1% than in the control poultry house.
