Evaluation of the effect of a chlorella-based feed additive (Chlorella vulgaris Beijer) on the productivity of Loman Brown cross laying hens

The article presents the results of the study of the effect of the feed additive “Algobooster” based on chlorella (Chlorella vulgaris Beijer) on the productivity Loman Brown cross laying hens. The research was carried out in the conditions of a peasant farm located in the Leninsky district of the Moscow region. The experiment was carried out on three groups (15 birds in each group) of 200-day-old laying hens. In the first experimental group, Algobooster was given to each bird individually for 60 days at a dose of 2 ml per day, and in the second group – 4 ml per day. The control group received no additive. The results of the experiment showed that the introduction of the additive increased the egg production of laying hens: in the first experimental group, 30 additional eggs were obtained in comparison with the control, and in the second experimental group, 69 additional eggs were obtained. Thus, the use of the feed additive “Algobooster” in the dosage of 4 ml/head made it possible to achieve an economic effect by increasing the productivity of laying hens with an increase in profit of 42 rubles.
