Popis: The objective of this study was to determine the effect of palm and/or linseed oil (LSO) supplementation on carcass quality, sensory evaluation and fatty acid profile of beef from crossbred Wagyu beef steers. Twenty four fattening Wagyu crossbred beef steers (50% Wagyu), averaging 640±18 kg live weight (LW) and approximately 30 mo old, were stratified and randomly assigned in completely randomized design into 3 treatment groups. All steers were fed approximately 7 kg/d of 14% crude protein concentrate with ad libitum rice straw and had free access to clean water and were individually housed in a free-stall unit. The treatments were i) control concentrate plus 200 g/d of palm oil; ii) control concentrate plus 100 g/d of palm oil and 100 g/d of LSO, iii) control concentrate plus 200 g/d of LSO. This present study demonstrated that supplementation of LSO rich in C18:3n-3 did not influence feed intakes, LW changes, carcass and muscle characteristics, sensory and physical properties. LSO increased C18:3n-3, C22:6n-3, and n-3 polyunsaturated fatty acids (PUFA), however, it decreased C18:1t-11, C18:2n-6, cis-9, trans-11, and trans-10,cis-12 conjugated linoleic acids, n-6 PUFA and n-6:n-3 ratio in Longissimus dorsi and Semimembranosus muscles.
