Supplementation of different fat sources affects growth performance and carcass composition of finishing pigs

Abstract Background There are various fat sources with different energy values and fatty acid compositions that may affect growth performance and carcass composition of grow-finishing pigs. A higher net energy was recently reported in choice white grease compared with soybean oil. Therefore, two experiments were conducted to determine whether practical responses confirm that difference between choice white grease and soybean oil, and to extend the observations to other fat sources. Results In Exp. 1, pigs fed fats had lower (P
