The prospects of Hedysarum alpinum L. and Inula helenium L. above ground parts application as food additives-phytogenies in pigs breeding

Now in agricultural practice, in connection with an increase in requirements to food security, feed additives of vegetable origin – phytogenics are more and more widely applied. These diet components are used, basically, in pig-breeding and poultry farming, and are intended for increasing livestock efficiency, reproduction stimulation and improvement of production consumer properties. Phytogenics possess antioxidant, antibacterial and immunomodulating properties. Their main advantage in comparison with preparations of synthetic origin is that they increase efficiency of forages consumption, stimulate digestion, reduce morbidity and, finally, increase production profitability. They do not worsen the quality of production and do not increase the risk of resistance to pathogenic microorganisms’ development in humans and animals. In Siberian Botanical Garden of Siberian State University and Scientific Research Institute ofAgriculture and Peat the prospects of above-ground parts of the plants Hedysarum alpinum L. and Inula helenium application as phytogenics are studied. Hedysarum alpinum L. is a perennial grassy plant, possessing a rich range of phy-tochemical compounds —flavonoids, alkaloids, benzopyrones and tannins. The greatest interest is presented by high contents of xanton mangiferin, possessing antiviral, antibacterial, immunomodulating and anti-inflammatory activity. There is officinal drug «alpizarin» applied in treating virus infections. One of the types of Hedysarum, H. cor-onarium, is applied in veterinary practice as anthelmintic and immunomodulating. Inula helenium, a perennial grassy plant, is very widespread, as well. The above-ground part of the plant contains terpenoids, alkaloids, phenolcarbon acids, benzopy-rones and flavonoids, possessing a wide range ofpharmacological properties, first of all anti-inflammatory and antibacterial. The plant is widely used in traditional medicine. When applying in pig-breeding, infusions and tinctures of Inula helenium increase the content of erythrocytes and the level of hemoglobin in the blood of animals and are applied as anthelmintic agents. In experiments on a commodity farm, the influence of plants preparations (infusions) on indicators of incidence, safety and additional weights of piglets of the first month of life were studied. Two experiments were made during the winter period against the outbreak of gastrointestinal infections, two - during the late spring period on a quiet infectious background. The efficiency of preparations was more expressed during the winter period on a complicated infectious background; in comparison with control, the rate ofpiglets survival from gastrointestinal and lung infections increased by 30-34%, the weight gain increased in 1.5-2.7 times. In the absence of a high level of infectious diseases, the application of herbal infusion promotes an increase in live weight ofpigs by 10%. Thus, application of these preparations is more expedient under conditions of the complicated infectious background.
