Enrichment of quail farming products by an important for humans source of useful fatty acids

Poultry farming is practically the only industry capable of providing the population with functional food products of animal origin in a short time. The production of the most accessible, functional poultry products for all segments of the population can be achieved by targeted feeding of poultry. Enrichment of poultry products with an important source of healthy fats for humans can be achieved by providing them with targeted feeding based on the inclusion in the poultry diet of feed ingredients obtained from the seeds of agricultural crops. The purpose of the work was to study the intravital change in the fatty acid composition of quail eggs when using functional feed raw materials from flax processing products used in the diet of laying quails of an industrial herd. It have found by the studies that when replacing sunflower oil with linseed oil and using flax flour in compound feed for laying quails of the experimental groups, the content of α-linolenic acid in the feed increased by 7.43 and 6.60 abs.%. The use of experimental compound feeds had a positive effect on lipid metabolism. Thus, with the same lipid content in the egg yolk, the content of polyunsaturated fatty acids of the ω-3 class was higher such as α-linolenic by 2.25–8.00 abs.% and docosahexaenoic by 1.25–2.10 abs.%. This entailed a change in the ratio of ω-6 to ω-3 fatty acids in quail eggs. Thus, in the control group it was 13.5:1, and in the 1st and 2nd experimental groups it was 4.77:1 and 1.98:1. Consequently, the use of flaxseed processing products in compound feeds for laying quails allows us to regulate the ratio of fatty acids, thereby improving the consumer qualities of quail eggs.
