The work was performed in Rozdilnyanske LLC of Rozdilnyansky district of Odessa region. For research, 5 groups of suckling ewes of the Gypsy breed were formed with 10 heads each, one of the groups was a control. Groups were formed by the method of analogue groups taking into account the breed, age in lambs, live weight, which was 50 kg. Chlorella microalgae suspension was fed to ewes in the first 20 days of lactation, in the amount of 3; 5; 7; 9 ml per 1 kg of live weight. Growth intensity, external parameters, and hematological and biochemical composition of blood were determined in newborn lambs at the age of 20 days according to generally accepted methods. It was found that feeding a suspension of chlorella microalgae to lactating ewes at the rate of 3, 5, 7, 9 ml per 1 kg of live weight increases milk productivity by 2.6-4.4 times and live weight of the offspring by 58.8-96.9%, compared to ewes that did not use chlorella microalgae suspension. With an increase in the amount of chlorella microalgae suspension in the diet of lactating ewes, the absolute increase in live weight of their offspring increases by 2.4-4.5 times. The average daily increase in live weight of lambs ranged from 199 g to 339.5 g
