Abstract
Neutral extractives of spruce needles were produced from forestry by-products: the green biomass of spruce needles. The extractes of spruce needles extract con¬tains a significant amount of natural biologically active substances. In the course of our investigations, the evaluation of biologically active substances obtained from neutral extracts of spruce needles was carried out to assess their effect on quality of broiler chicken meat. The feeding trial was conducted with broiler chickens of the cross ROOS – 308 by adding neutral extract of spruce needles in the form of loose powder to the com¬position of broiler chicken diet. It was found that the loose powder feed additives containing neutral extract of spruce needles (0.05% and 0.10% in pure substance) used to supplement the broiler feed improved the quality of poultry meat. The feed additives containing biologically active substances from spruce needles neutral ex¬tract involved in metabolic processes of the broiler chicken organism, increased the n – 3 polyunsaturated fatty acids (DHA) content in meat by 0.59 – 1.05% and the carotenoids’ content in liver by 1.46 – 1.70 mg kg -1, at the same time positively reducing the cholesterol level in meat by 17.18 – 26.16 mg 100 g-1 in comparison with the control group.
