Evaluation of animals according to indicators of individual development, fattening, and meat qualities were carried out taking into account the following characteristics: live weight of young pigs on the last day of control fattening, kg; body length, cm; chest circumference behind the shoulder blades, cm; average daily gain of live weight during the period of control fattening, g; the age of reaching 100 kg live weight, days; length of the cooled carcass, cm; thickness of bacon at the level of 6-7 thoracic vertebrae, mm. The Eurosomia index was calculated due to the methodology of S. V. Akimov (2005), the biometric processing, and the analysis of the economic efficiency of the research results were carried out according to generally accepted methods. It was founded that the young pigs of the large white breed of the controlled population correspond to the 1st class and the elite class in terms of body length, age of reaching a live weight of 100 kg, lard thickness at the level of 6-7 thoracic vertebrae and length of the chilled carcass. It was established that the young pigs of the first experimental group reliably outperformed peers of the second experimental group in terms of live weight on the last day of control fattening, body length, chest girth behind the shoulder blades, average daily increase in live weight during the fattening control period, age reaching a live weight of 100 kg, the length of the chilled carcass, the length of the bacon half of the chilled half carcass by an average of 2.77%. The coefficient of discreteness of signs of individual development, fattening, and meat qualities in young pigs of the experimental groups ranges from 0.427 to 0.829 points. The presence of reliable connections (87.50%) between the Eurosomia index, development indicators, fattening, and meat qualities testify to the effectiveness of using this integrated value in selection and breeding work under conditions of compliance with the optimal level of feeding and maintenance and veterinary safety. The maximum increase in additional production was obtained from young pigs of the 1st experimental group - +2.35%, and its value are +162.47 hryvnias or 4.11 US dollars.","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89537514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high demand for poultry products leads to a rapid increase in the number of broiler chickens both in the world and in Ukraine, and at the same time to an increase in the volume of poultry waste, especially droppings and litter. Intensive and uncontrolled use of fresh broiler droppings as organic fertilizer for agricultural plants has a number of economic and ecological disadvantages. Therefore, there is a need to store (ferment) the broiler chickens droppings for a certain period of time (up to 20 months) in order to use it safely in crop production. Bacteria play an important role in the course of enzymatic processes in poultry droppings during its storage. It is of scientific interest to determine the number of bacteria in the droppings of broiler chickens with litter (cereal straw) stored for different times in the cold season. The content of microorganisms was determined in the droppings of broiler chickens. Samples were taken in January at an air temperature of 1.3 °C under the conditions of the experimental farm of the Bila Tserkva National Agrarian University from droppings 2 days after unloading from poultry houses, and which was stored for 4 and 9 months in barns. The content of CFU Bacillus spp., Staphylococcus spp., Streptococcus spp. and Escherichia coli was determined in the litter. The indicator of KMAFAnM in the droppings of broiler chickens unloaded from poultry houses was 3.5x108. Until the 4th month of storage of the droppings, the KMAFAnM indicator in it increased. For 9 months of storage, the index of KMAFAnM in the droppings of broiler chickens decreases by 58.7 times compared to the index obtained after 4 months of composting. A group of bacteria Bacillus spp. was represented by the following species: Bacillus subtilis (dominant), Bacillus mesentericus, Bacillus megaterium and Bacillus mycoides. Colonies of Bacillus spp. sown from droppings of different periods of storage were dry, with a wrinkled surface. They were colorless and light velvety in color. The edges of the colony of this bacterium were wavy. The lowest rate of CFU Bacillus spp. was found in the droppings unloaded from poultry houses. The number of CFU Bacillus spp. in droppings that was stored for 4 months was the largest. In broiler droppings that was stored for 9 months, the CFU indicator of Bacillus spp. was 10 times lower compared to droppings that was stored for 4 months. A group of bacteria Staphylococcus spp. was represented mainly by the following species: Staphylococcus aureus and Staphylococcus saprophyticus. CFU index of Staphylococcus spp. in the droppings unloaded from the poultry houses was 4.6x107. The largest number of CFU Staphylococcus spp. was found in droppings that were stored for 4 months. In the droppings of broiler chickens after 4 months of storage, the CFU index of Streptococcus spp. was greater than at the beginning of storage by 28","PeriodicalId":21617,"journal":{"name":"Scientific and Technical Bulletin оf State Scientific Research Control Institute of Veterinary Medical Products and Fodder Additives аnd Institute of Animal Biology","volume":"140 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73562733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under these conditions, the ability of the organism to mobilize protective and adaptive capabilities in response to the action of negative technological and environmental factors becomes especially important. Micronutrients and vitamins play a leading role in mobilizing the body's adaptive capabilities.
