| Popis: | The fish diet exerts a great influence on its centesimal composition as well as the content of cholesterol and fatty acids. The use of coconut meal may represent alternative source in the fish diet in view of the cost and the availability in the Northeast of Brazil. The purpose of this work was to assess the impact of the use of coconut meal in feed for Nile tilapia (Oreochromis niloticus Linnaeus, 1857) on the nutritional value of fillet. 120 fingerlings of fish reversed were used, distributed in 20 boxes of polyethylene, containing 6 experimental units per boxe. The experiment was conducted in a completly randomized design with 4 treatments (T1 - 0%, T2 - 10%, T3 - 20% and T4 - 30% for the inclusion of coconut meal) and with five repetitions. After 90 days, the fish were slaughtered and the fillet was removed and the proximate composition, cholesterol and fatty acids were determined. There was a difference (p |
