In the conditions of the Republic of Belarus there was studied the propagation, botanical characteristic, chemical composition and pharmacological properties of marsh cinquefoil (Comarum palustre) and its application in the veterinary practice against strongylatosis (Strongylata) of gastrointestinal system of cattle young stock. Reserch results showed that the perennial herbage plant marsh cinquefoil from Rosales (Rosaceae) family possessed different therapeutic properties: antipyretic agent; styptic agent; diuretic agent; bonding agent; wound healing substance; tonic agent; promotoring agent. Research results showed that the preparative forms (broth; liqueur; liquid juice; powder) of marsh cinquefoil possessed an active agent proanthocyanidin, a condensed tanning substance which were included into composition of a polyphenolic complex and proved to be efficient for treatment of cattle young stock strongylatosis.

Japanese millet (Echinochloa frumentacea) growing and yielding capacity was estimated in single and mixed sowings cultivated on sod-podzolic light loamy soils in the conditions of the Republic of Belarus; as well as comparative evaluation of silage quality and determination of digestibility of nutrients. Field experiment with forage crops was realized in threefold replication in accordance with the following scheme: Japanese millet (100%); Japanese millet (70%) + vetch (Vicia) (30%); Japanese millet (70%) + lupine (Luoinus) (30%); Japanese millet (70%) + pea (Pisum) (30%); Japanese millet (70%) + soybean (Glycine max) (30%). Research results showed that mixed sowings of Japanese millet with bean cultures made it possible to obtain higher yields than single sowings on 5,9-15,6%. Silage made of Japanese millet with bean culture contained higher amount of crude protein on 2,73-3,98% in comparison with silage which was produces only from Japanese millet. Silage produced from Japanese millet mixture with high protein crops had high energy and protein value: 0,90-0,92 fodder units; 9,47-9,59 mJ of metabolic energy per 1 kg of dry matter and 102-103 g of digestible protein per 1 fodder unit

For soil – climatic conditions of a northeast part of the Republic of Belarus is recommended cultivating four-componential – fodder grass with two leguminous components (meadow clover + Lucerne sowing+ meadow timothy+ meadow fescue), productivity of which green weight has made 500 – 550 centers per hectare, gathering of crude fiber-19-21 centers per hectare. Inclusion of Lucerne sowing in clover-cereal fodder grass has provided a share of a leguminous component on average for four years no less than 75%
