Abstract: A scientific - economic experiment with a total number of 21 Danube White pigs, divided into 3 groups of 7 pigs each was carried out at the Agricultural institute – Shumen. The experiment was started at 34.714–34.857 кg live weight and finished at 109.286–110.71 kg. The aim of the present study was to investigate the effect of the addition of Spirulina platensis on the productivity, some blood parameters and percent lean meat on fattening pigs. The addition of microalgae Spirulina platensis (2 and 3 g/capita daily) in the compound feed of fattening pigs (from 34.714–34.857 кg to 109.286-110.71 кg live weight) from Danube Write breed was appeared tendency to increasing the growth intensity by 2.13 % - 4.57 % and better feed conversion by 3,61 %. The addition of microalgae Spirulina platensis in the compound feed of fattening pigs did not influenced of red blood indexes. Including Spirulina platensis in the compound feed increased the percent of lean meat by 12.60% (P ≤ 0.05) and reduced backfat thicknees by 14.29-37.13%.
