SANTOS, E. L. et al. Performance of Nile tilapia fingerlings fed dehydrated cassava leaf in the diet. Arq. Bras. Med. Vet. Zootec. [online]. 2015, vol.67, n.5, pp.1421-1428. ISSN 1678-4162.  http://dx.doi.org/10.1590/1678-4162-8200.

ABSTRACT

The aim was to evaluate the growth and the economic viability of the Nile tilapia (Oreochromis niloticus) fed with different levels of dehydrated cassava leaf flour in the diet (FFMD). 80 fingerlings were distributed into 20 18L containers, consisting of a water recirculation system over a period of 51 days. 100 copies fed three times a day to satiation were randomly assigned in a completely randomized design, constituting 4 treatments (0%, 5%, 10% and 15% addition of FFMD in diet) with 5 repetitions each. The fishes fed with 10% FFMD had better homogeneity in growth. However, individuals fed with inclusion of 5% FFMD homogeneity grew similarly to those fed with 10% FFMD. In addition, the fish from the 5% had better growth performance and economic viability of the feed. Thus, it is recommended to use 5% of dehydrated cassava leaf meal in diets for Nile tilapia.
