The best method of increasing long chain ω-3 PUFA consumptionwould be to increase the long chain ω-3 PUFA content in the edible tissues ofpoultry aimed for human diets. It has been shown that heart and blood vesseldiseases, as well as the occurrence of atherosclerosis are a direct consequence ofconsuming products of animal origin in human nutrition which contain a highcontent of lipids rich in saturated fatty acids (SFA), which are the main causesof these diseases. For these reasons healthy foods enriched in PUFAs, particularlyω-3 fatty acids, have gained high importance because of their beneficial effects onhuman health.Apart from the importance of being able to predict chicken carcass conformationit is also necessary to calculate the required level of fatty acids in the chicken dietthat are incorporated into the edible tissues. Regression analysis is most often usedfor this prediction. The goal in regression analysis is to create a mathematical modelthat can be used to predict the values of a dependent variable based upon the valuesof an independent variable. The aim of this paper is to show possible solutions forbroiler edible tissue enrichment with ω-3 fatty acids from linseed, and to givepossible solutions to the inclusion level of fatty acids in the diets using regressionanalyses.Keywords: linseed; ω-3 fatty acids; regression; nutritiondoi:10.1017/S0043933914000634© World's Poultry Science Association 2014World's Poultry Science Journal, Vol. 70, September 2014Received for publication November 15, 2013Accepted for publication February 10, 2014 585
