| Popis: | A 75-day feeding trial was carried out to examine the effects of fish oil (FO) replacement with various alternative vegetable oil (VO) on the growth performance and feed utilization efficiency of red hybrid tilapia (Oreochromis sp.). The VO evaluated included canola oil (high in monoenes), perilla oil (high in n − 3 polyunsaturated fatty acids, PUFA), sunflower oil (high in n − 6 PUFA) and refined, bleached, deodorized palm olein (high in saturates) added as the sole lipid source in semi-purified experimental diets. The ability of hybrid tilapia to biosynthesize long chain-polyunsaturated fatty acids (LC-PUFA) from dietary 18:2n − 6 and 18:3n − 3 was also determined. With the exception of sunflower oil, results showed that total FO replacement by various VO did not compromise (P > 0.05) tilapia growth performance. However, dietary VO significantly (P |
