A study was performed to evaluate the effects of melamine (Me) and urea formaldehyde (UF) combinations in diets on growth performance, and characterization of toxicity appearance. The combinations of three levels of Me and UF (0.5, 1.0 and 2.0%) were conducted with one control (no addition) in a completely randomized design (CRD). Four hundred and eighty mixed-sex fish with the initial weight of 9.67±0.03 g were assigned to 10 dietary treatments with 3 replications and fed for 6 weeks. No interaction was observed between Me and UF in this study. However, significant differences (P<0.05) in growth performance, feed efficiency and survival rate (SR) between the control and the fish fed with Me and UF combinations were observed. The body weight (BW) and... |
