MICROBIOLOGICAL STUDIES OF RAW MATERIALS AND COMPOUND FEEDS FOR VALUABLE FISH SPECIES

The article presents the influence of the extrusion method on the sanitary condition of the finished compound feed, as well as studies of the quantitative and qualitative composition of the microflora of raw materials of plant and animal origin used in the production of compound feeds for valuable fish species (jade perch, pike, walleye). Compound feeds were developed in the conditions of the Golden LLP plant Fish.kz", the study was conducted at the Kazakh Research Institute of Processing and Food Industry in Almaty. Studies have been conducted to identify pathogenic microflora in 4 samples of raw materials (fish meal, meat and bone meal, wheat, rapeseed meal) and in 3 samples of extruded compound feeds (compound feed for jade perch, pike and walleye). The analysis of the listed raw materials objects showed that the detected total microbial number of pathogenic microorganisms and conditionally pathogenic do not exceed acceptable indicators. The analysis of 3 samples of finished compound feed showed that the samples after extrusion are sterile and the results of studies of the sanitary condition of experimental extruded fish feeds indicate that the heat treatment of the raw materials used in the production process ensures appropriate requirements for the quality and safety of compound feeds in relation to the established microbiological standard and the use of these products for fish cultivation.
