Sažetak

Dry biomass of algae is a good source of nutrients and biologically active substances, which in the last years attracted the interest of the specialists in their search for natural, ecologically and healthy sound foods for the animals. The aim of the present study was to characterize the chemical composition and the nutritive value of the dry biomass of fresh water algae of Chlorella genus cultivated in Bulgaria and to establish its effect on the laying hen productivity and the morphological characteristics of the table eggs. The tested product was analyzed for its crude protein content – 55 % to available wet, crude fats – 9,6 %, crude fi bres – 6,4 %, xanthophylls – 0,6 g/kg, essential amino acids: lysine – 5,5
%, methionine – 1,2 %, triptophan – 1,2 %. Adding 2 % and 10 % of dry biomass of fresh water algae of Chlorella genus to the combined forages for laying hens led to the improvement of the bird productivity and the morphological characteristics of the eggs and the egg yolk pigmentation was more intensive by 2,5 units by the Roche’s scale.
