New feed ingredients in the form of dry loose powder contained spruce: pine needles extractives on the basis of calcium carbonate and are dark green in color. Dry loose powder feed ingredient was produced from forestry by products - spruce: pine needles total extractives in equal proportions (1:1).
During our investigations the evaluation of new feed ingredients was carried out to assess their effects on productivity and quality of broiler chickens meat. Chicken of the cross ROSS – 308 were included in the feeding trial. The new feed ingredients, containing biologically active substance from spruce: pine needles extract, involved in metabolic processes of the broiler chicken organism system. The dose of new ingredients added to basic feed ration homogenously bound to other feed ingredients. It was found, that the new loose powder feed ingredients used to supplement the broiler feed improved the quality of meat.
That increased the composition of fatty acids in meat, increased the amount of n-3 polyunsaturated fatty acids by 2.73% including EPA and DHA fatty acids by 0.26 – 1.25% and positively reduced the calculated IA (index of atherogenic) and IT (index of thrombogenic) levels by 0.09 – 0.06% in comparison with the control group.
The new feed ingredients in poultry diet particularly decreased the cholesterol level in meat by 15.61 mg 100 g-1 or by 21.2% in comparison with the control group.
By using new feed ingredients containing total extractive from spruce: pine needles in diet broiler chickens it’s was possibility to obtained meat with innovative composition.

Keywords: broiler chickens, extractives of spruce : pine needles, meat quality.
