Abstract
Slyusarenko I., Kitayeva A., Susol R. 2021. Effect of chlorella microalguston suspension on dairy productivity of sheep mothers and growth intensity of lambs. Acta Biol. Univ. Daugavp., 21 (2): 117 – 126.
For this research, 5 groups of lactating ewes of the Gypsy breed were formed with 10 heads in each, one of the groups was a control. Groups were formed by the method of analogue groups taking into account the lambs breed, age, live weight, which was 50 kg. Ewes were fed with chlorella microalgae suspension 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. 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 with ewes that did not consume chlorella microalgae suspensions. 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. Increasing the amount of chlorella microalgae suspension from 3 to 9 ml per 1 kg of live weight contributed to an increase in milk productivity by 2.6-4.4 times and an increase in milk fat by 3 , 0-3.9%. Morphological and biochemical parameters were within the physiological norm. Higher milk productivity of ewes is accompanied by greater activity of blood enzymes. The best indicators of increasing milk productivity and
live weight gain of offspring were obtained when ewes were fed with 9 ml of suspension of chlorella microalgae per 1 kg of live weight.
