Rice blast caused by Pyricularia oryzae is a major disease affecting rice production grown in upland and wetland rice. Application of biotechnological approach to protect against the disease may be an alternative strategy to chemical control

The article analyzes the possibility of complex processing of one of the most important secondary raw materials of Krasnodar region – sugar beet pulp with the aim of obtaining a food product and enriched feed additives. Meanwhile, the use of environmentally safety technologies that cause minimal harm to the environment and human health is provided. One of the most valuable components of sugar beet pulp after extraction of sugar is pectin substance. Sugar beet pectin substances have high complexing ability and are used not only in food industry, but also in medicine. They are natural detoxifiers and antioxidants. Currently, only dry powder pectin is produced from sugar beet pulp and only by foreign producers. Making food pectin extracts from sugar beet pulp will not only reduce the number of processing steps, but also significantly reduce the cost of the final product. Food pectin extracts can be used not only as a standalone product in treatment and prophylactic nutrition, but also as an ingredient in the manufacture of soft drinks, confectionery and bakery, meat and dairy products, etc. The technology of producing a valuable component of feed bioproduct based on spent sugar beet pulp and a microscopic fungus of the genus Trichoderma is described

The purpose of the research is to compare the effect of a new symbiotic feed supplement created based on propionic and lactic acid bacteria with a widely used domestic and foreign enzyme-probiotic preparations in chickens 0-28 days of age of the Lohmann Brown egg cross. In the experiment, there were six groups of chickens: group 1 received basal diet (BD); group 2 – BD + symbiotic preparation; group 3 – BD + Bacell; group 4 – BD + Agrocell; group 5 – BD + Agroksil; group 6 – BD + Ollzaym Vegpro. Average daily gain, food conversion rate per 1g of weight gain, digestibility of organic matter, crude protein, crude fiber, crude fat, made up respectively: group 1 – 8.17, 1.91, 71.4, 58.3, 68.0, 81.1; group 2 ˗ 8.36, 1.90, 72.4, 60.2, 69.7, 88.1; group 3 – 8.13, 1.91, 73.1, 60.2, 69.7, 88.1; group 4 – 8.33, 1.86, 74.2, 62.5, 72.2, 87.6; group 5 – 8.50, 1.83, 77.3, 64.1, 73.4, 95.4; group 6 – 7.91, 1.92, 73.2, 67.5, 70.7, 94.3. The growth rate of chickens fed with symbiotic feed supplement was 2.3% higher than in the control and they showed the highest fiber digestibility. The chickens on diet with Agroksil enzyme efficiently raised growth rate (+4%) and reduced feed costs (-4.2%). Agrocell increased weight gain by 2% and reduce feed costs by 2.6%. The growth rate of chickens fed Ollazaym Vegpro was the lowest (96.8% of control), despite the fact that it increased significantly the digestibility of crude protein, but slightly improved the digestibility of other nutrients. Outcome: symbiotic feed supplement may be of interest as a means of increasing the productivity of chickens
