Regarding animal feed, the amount of protein feeds produced in Serbia does not meet requirements of animal production, so the majority is imported. In order to resolve this issue, intensified domestic production of oilseed rape has occurred, due to low cost and progress in variety selection. Canola, a crop variety of more recent date, contains 38-48% oil, 18-28% protein, less than 10 μmol glucosinolate/g and less than 0.1% erucic acid, thus enabling wider use of this feed in poultry nutrition. However, due to the high fiber content and low energy value, the use of canola meal is limited in the nutrition of non-ruminants (Stanacev et al., 2011; Stanacev et al., 2012). For this reason, more extensive use in animal feeding systems is not possible (Stanacev and Kovcin 2004). It is to be noted that properly ground canola seed is efficiently digested. However, as a consequence of its rather tiny seeds and the absence of adequate milling technology to properly destroy the tissue structure and crush the seeds, thus making nutrients inside seeds available to enzymes, canola seed has not been able to be efficiently digested by animals in the past. There is growing interest in canola in recent years, because it is a good source of energy and polyunsaturated fatty acids, linoleic and linolenic acids, in particular. The objective of this study was to investigate effects of extruded canola seed on the chicken fatty acid composition of lipids and nutritive quality of chicken meat.
