| ABSTRACT Water lentils (Duckweed [DW])(Lemna gibba), in irrigation ponds, was evaluated by replacing two levels of soybean meal (SBM) on performance and egg quality of laying hens of 54 weeks of age. A total of 72 white Lohmann laying hens were randomly allocated into 3 treatments with 6 replicates/treatment, 4 hens/replicate in a randomized complete block design. Treatments were: control group (DW0%) with (SBM) as the main source of protein, T1 (DW10%) and T2 (DW20%), where duckweed replaced 10% and 20% of SBM for 9 weeks. No significant differences were observed among the dietary treatments in body weight change, feed conversion ratio, egg weight and mortality rate. Replacement with (DW20%) decreased (p<0.05) feed intake, egg laying rate and egg mass.... |

| The objective of this work was to evaluate corn gluten meal (CGM) as a substitute for fish meal in diets for striped catfish (Pseudoplatystoma fasciatum) juveniles. Eight isonitrogenous (46% crude protein) and isoenergetic (3,450 kcal kg-1 digestible energy) diets, with increasing levels of CGM - 0, 6, 12, 18, 24, 30, 36, and 42% -, were fed to juvenile striped catfish (113.56±5.10 g) for seven weeks. Maximum values for weight gain, specific growth rate, protein efficiency ratio and feed conversion ratio, evaluated by polynomial quadratic regression, were observed with 10.4, 11.4, 15.4 and 15% of CGM inclusion, respectively. Feed intake decreased significantly from 0.8% CGM. Mesenteric fat index and body gross energy decreased linearly with increasing... |
