Prospectivity of use of medicinal and feed grass for production of organic feed additives for animal feeding

Abstract

Goal. Establish the most productive types of medicinal and forage grasses for the formation of phyto-mixtures based on them to obtain organic feed additives for animal feed. Methods. Field, laboratory, animal testing by group method, means of variation statistics. Results. On the basis of the conducted researches the optimum terms of collecting of medicinal and forage grasses are established. According to the yield of dry mass, the most productive are milk thistle (3.6–4.2 t / ha), еchinacea purpurea (3.3–4.7 t / ha), fennel (3.0–4.0 t / ha) and the Moldavian snakehead (2.8–4.3 t / ha), and by the seed yield is coriander (0.3–1.8 t / ha). Hyssop, lofant anise, yarrow and shandra are also quite productive. During the years of research, annual wormwood, cephaloflora fragrant, cha­momile and cumin remained unclear for the production of raw materials. In addition, the height of these plants is low and they are not able to successfully control weeds, and the use of herbicides in the conditions of growing organic raw materials is impossible. At the full dose of organic phyto-mixture (includes seven components of herbs containing BAS, with a dry weight of 570 g), the effectiveness of its application on dairy cattle was highest and was 2 liters of milk per cow per day or 10%. Conclusions. The best for use in production is the full dose of organic phytocomposition, which provides an increase in daily milk yield by 2 liters per cow or 10% and increase the fat content in milk by 0.5% (25% due to the nutritional value of the additive and 75% due to action its BAR), which provides 25-35 UAH of profit per cow.
