Item Relação energia: proteína em dietas para Tilápia-do-Nilo (Oreochromis niloticus)(2019-07-09) Lima, Isislayne Estevão de; Cavalcante, Danilo Teixeira; http://lattes.cnpq.br/6476444073756661; http://lattes.cnpq.br/2307580627849007The aim of this research was to determine the best proportion between protein-energy on the performance of Nile Tilapia juvenile.The experiment was carried out at the Aquaculture Research Laboratory (LAPPIS) of UAG / UFRPE. A total of 405 male Nile tilapia juveniles were used, distributed from a completely randomized design in three treatments and 9 replicates with 15 fish in 27 glass tanks (160L) equipped with water recirculation system, biological filter, ultraviolet filter and supplementary aeration. The treatments consisted of different protein-energy levels, defined as low (0.53), medium (0.69) and high (0.96). Final weight (g), feed intake (g/day), weight gain (g/day) and feed conversion (g) were measured. The data were submitted to ANOVA, using SAS software version 9.1. When significant, the averages will be compared by the Tukey test at 5% probability. The higher starch:protein level promoted higher final weight (P = <10001), higher weight gain (P = <10001) and better feed conversion (P = <10001) in the fish, without any influence on the feed intake (P = 0.321). Diets with a low proteinenergy level (39% crude protein and 20% starch) are best indicated in 1 to 20 days, and from 21 days onwards diets with a high protein-energy level (31% crude protein and 30% starch).Item Relatório do estágio curricular supervisionado obrigatório: produção animal na empresa Agroceres(2019-01-10) Lima, Isislayne Estevão de; Cavalcante, Danilo Teixeira; http://lattes.cnpq.br/6476444073756661; http://lattes.cnpq.br/2307580627849007
