Six feeding rates ranging from 1% to 11% in trial I and another six feeding rates ranging from 1% to 6% in trial II were tested. Final body weight, weight gain, feed conversion ratio, condition factor, nutrient gains, and whole-body lipid and energy contents were significantly influenced by the feeding rates in both trials. The overall responses shown in trial I were generally comparable to those observed in trial II. In trial I, the OFR was estimated to be 7.3%, 5.7%, 9.8% and 10.2% by the one-slope straight broken-line, two-slope straight broken-line, quadratic broken-line and quadratic models, respectively. In trial II, the OFR was estimated to be 4.8%, 4.6%, 8% and 8% by the one-slope broken-line, two-slope broken-line, quadratic broken-line and quadratic models, respectively. Based on the model selection criteria (R2adj and AICc), the quadratic broken-line model was selected as the best-fit model in both trials. This model that describes the dose–response relationship best among the tested models can be recommended when determining an OFR.
