Abstract
Kazakhstan is implementing government initiatives aimed at reducing dependence on imports and developing domestic feed production. In modern realities, it is extremely important to use effective methods of feed conservation that guarantee minimal loss of nutrients, as well as optimal profitability and labor organization. Assessment of microbiological safety and toxicity of feed additives during storage is a mandatory procedure, since infection with spore – forming bacteria and mold leads to significant degradation of nutritional value and product quality. As part of this study, poultry feed was analyzed one, four, and six months after the start of storage. The increase in the number of microorganisms in feed during long-term storage is explained by the presence of spores in them. Under suitable conditions, these spores germinate, forming vegetative cells, which then actively multiply and function. In addition, there is a risk of spores formed by various microorganisms entering the product from the environment – air, dust and moisture. The research methods used in the project comply with generally accepted standards. Both experimental and experimental samples were used in the work. After packing the experimental samples in various types of containers, they were processed using an IL-10 electron accelerator. Paper bags, bag bags and vacuum-polyethylene packaging were used as packaging materials. Mycotoxin content was monitored during the entire storage period – 1, 4 and 6 months. The data obtained indicate that after six months of storage, mycotoxins were detected in feed packed in paper bags and not treated with IL-10, as well as a decrease in other quality indicators. Studies have shown that maximum microbiological protection is achieved when stored in an airtight polypropylene container, which ensures the safety of feed for six months.
