Abstract: The objective of the research was to estimate the influence of cyanobacteria Arthrospira (Spirulina) platensis biomass additive on cows' body condition, milk productivity and biochemical indexes at the beginning of lactation. Two parallel groups of Lithuanian black and white cows in their early lactation period were used for the experiment. During the 90-day experimental period, they were fed on almost the same ration: the experimental group received 200 g of cyanobacteria Arthrospira (Spirulina) platensis additives daily, mixed with the combined feed. The body condition of cows was scored according to a 5-point scale system in their dry period, after calving, and after the first, second or third month of lactation. Their productivity, milk composition and quality indexes were estimated during control milking: milk yields - on the farm and rates of composition and quality - in the laboratory of SE 'Pieno tyrimai'. The experiment showed that the cows of the experimental group which received 200 g of cyanobacteria Arthrospira (Spirulina) platensis daily during the experimental period became 8.5-11 percent fatter (P < 0.01). Each gave on average 34 kg milk per day in the beginning of their lactation, or 6 kg more than those from the controlled group (P < 0.05). Throughout the 90-day experiment, the average income from the milk of one cow from the experimental group was 378 Lt, or 21% more than from the controlled group. The use of cyanobacteria additives was economically effective, because 1 Lt costs for 'Spirulina platensis' increased income from the milk by 8.4 Lt
