Feeding value and crop yield of some feed plant species distributed in the north-eastern part of the Lesser Caucasus

The bioecological potential and resource potential of feed plants distributed on the pastures of the North-Eastern part of the Lesser Caucasus are studied. 440 Angiosperms species belonging to 171 genera and 27 families have been identified in the flora of the territory. The biological resources relatively wet and dry mass of some species were calculated in different years and were found the reserves of the Lotus corniculatus L., Dactylis glomerata L., Anthyllis lachnophora Juz. and Urtica dioica L. species respectively - 246.55 (59.2%); 198.0 (45.5%); 149.53 (32.9%); 135.4 (28.4%) centners on ha. For farmers advisable to use both dry and wet masses to enrich in the diet of animals. So, the yield of each species in 2019 increased compared to 2017-2018 years. Indicators of feed value were also analyzed for assess the feed value of these species, common among the meadow vegetation types. The species Dactylis glomerata L. should be distinguished according to the highest dry weight and crude protein (18.0%), and Lotus corniculatus L. - by the feed unit (0.22). Cultivate the highest yielding fodder plants and studies the indicators of fodder quality are necessary for accelerate the development of animal husbandry and obtain high-quality animal products.
