Obtaining of the goods production largely depends on the conditions of bees‘ families‘ maintenance, the honey, the local weather conditions, queens quality and other factors. The purpose of research is to determine the efficiency algal suspension "Chlorella Vulgaris" to feed the bees. Using algal suspension "Chlorella Vulgaris" contributed to better development of bee families. The highest number of capped juvenile was found on May 7, in bees families were was used algal suspension (162 hundred cells of capped juveniles or with 22.4% more than in the control group). Honey production in bees‘ families of experimental group increased by 17.0% compared with the control group, which was fed with sugar solution. There was noted that for growth of bee families during spring, when there is no natural gathering (nectar, pollen), it is reasonable to use algal suspension "Chlorella Vulgaris" with 1:1 sugar, one liter every 12 days, and at the queens growing from the time of larvae transfer till queens capping (5 days).
