DescriptionFerrourtikavit is a biologically active additive (BAA) derived from common nettle supplemented with micro nutrient elements (titanium, vanadium, molybdenum, zinc, copper, iron, tin, chromium, manganese, barium). Ferrourtikavit is manufactured from local vegetable raw materials, however its application in feeding dairy cows is not sufficiently studied. Therefore, the application of the BAA ferrourtikavit in animal feeding with a view to increase milk production is relevant. The aim of the research conducted is to investigate the impact of the BAA ferrourtikavit on the overall nutritional value of animal diet and reduction of food consumption. The experiment was conducted on four groups of black-motley breed dairy cows. Formation of the experimental groups (15 animals per each group) was performed on the third lactation, taking into account age, productivity during the previous lactation, breed characteristics, live weight. The main diet consisted of hay, haylage, succulent fodder, concentrates. Additionally to basic diet the 2nd , 3 rd and 4th experimental groups obtained the BAA ferrourtikavit at the doses of 0,25, 0,50 and 0,75 mg/kg of live weight, respectively. It has been established that the animals from the experimental groups (2nd, 3rd and 4th) consumed 43,9-51,3 energetic feed units less, 439,4-513,5 MJ metabolic energy less, 56,4 – 62,0 kg dry matter less, 1,1 – 1,6 kg digestible protein less. The lowest feed consumption was noted among the animals from the 3rd experimental group, in the basic diet of which the BAA ferrourtikavit in an amount of 0,50 mg/kg of live weight was introduced. The research conducted established, that application of the biologically active additive ferrourtikavit in the diet of lactating cows at the dose of 0,5 mg/kg of live weight led to the highest milk yields 4678±45,17 kg. In the experienced groups, increase in milk yields, decrease in concentrates' utilization as well as costs of 1 kg milk as compared to the control group were registered
