A decrease in the level of immunological reactivity and natural resistance of the body is one of the reasons for the decrease in the viability and safety of poultry. When used in feeding antibiotics, a number of undesirable side effects occur. Therefore, of particular interest is the use of phytobiotics to form the resistance of the bird organism to the effects of adverse environmental factors. Phytocompounds affect the processes of metabolism and neutralization of foreign substances, which are carcinogens and mutagens. They have the ability to bind free radicals and reactive metabolites of foreign substances, inhibit xenobiotic activating enzymes and activate detoxication enzymes. Phytobiotics have antiviral, antimicrobial, as well as immunomodelling effects. The main advantage of feeding herbal supplements is that the animals are not exposed to any risks; the possibility of their use as flavoring, appetite-stimulating substances is fully confirmed by the EU documents regulating nutrition. The range of such domestic drugs is narrow and not developed. Increasing the antioxidant status of the animal’s body by optimizing the level and quality of feeding, especially by adding exogenous antioxidants obtained from high quality raw materials, can be one of the most important and effective means of improving the health and, therefore, productivity of poultry. The study of the effect of feed additives made of the vegetative mass of amaranth on the resistance of poultry is a modern area of research in world science.

In the organization of scientifically grounded feeding of farm animals, the use of compound feed balanced in terms of basic nutrients ensures an increase in the productivity of animals by 10-12%, and when enriched with biological additives that contribute to the safety of livestock, an increase in the physiological status and productivity of animals, their effectiveness increases by 25-30 %. There is the issue of providing the population with high-quality livestock products, which can only be obtained with adequate feeding, which contributes to the intensity of animal growth, productivity and a decrease in feed costs per unit of production. An important WHO recommendation is to limit the consumption of processed and red meat products, due to the increased risk of developing cancer of the gastrointestinal tract in humans. One of the alternatives to red meat is rabbit meat. Rabbit meat is rich in polyunsaturated fatty acids, which interfere with carcinogenesis, inducing apoptosis, controlling the cell cycle and eicosanoid production, and also inducing antiproliferative effects. The main problem in industrial rabbit breeding is maintaining a high immune status of rabbits to increase the safety of livestock, productivity and meat quality. The use of non-traditional biologically active additives from agroindustrial complex waste in the composition of compound feed has been insufficiently studied. It is necessary to qualitatively change the nature of the feed base through the creation and use of effective biologically active feed additives and probiotics that have a protective effect and the ability to optimize the metabolic processes of the body, treat and prevent diseases of the gastrointestinal tract. It is possible to restore normal intestinal microflora, improve the bioavailability of nutrients in compound feed and increase safety of livestock without the use of antibiotics for therapeutic and prophylactic purposes. The comparative assessment of the effectiveness of the action of biologically active additives in the composition of feed for the development of rabbit breeding is of undoubted scientific and practical importance.

Recycling of biowaste is accompanied by its transformation into an economic product, while at the same time contributing to the protection of the environment and bringing benefits to public health. This article provides an overview of modern technologies for processing biowaste associated with their direct use, biological, thermochemical and physical-chemical processing. Direct use technologies include land use, feed, and direct combustion. The main options for biological treatment are composting, vermicomposting, and fermentation. Physical and chemical treatment includes transesterification, compaction, and thermochemical-pyrolysis, liquefaction, gasification. Sustainable recycling of biowaste requires a sufficient amount of waste as input and market demand for the products produced. For biowaste, such markets will depend on the end-use of the product. Not all the presented methods contribute to the preservation of the environment, so the search for environmentally friendly and at the same time cost-effective technologies is currently continuing. It is aimed at combining various biowaste processing technologies into a single system that has new advantages, taking into account productivity, resource intensity and environmental friendliness. Many scientists agree that the future of waste disposal is in nature-like technologies, because nature has all the necessary recycling mechanisms.
