| Abstract: | The experiment was conducted to study the requirement of crude fibre and enzyme preparation for goslings by using two factors quadratic regression orthogonal rotational combing design. The results showed as follows: The addition levels of crude fibre and enzyme preparation in diet were 5.098% and 0.258% respectively when the maximal average daily gain was 43.38 g; When the addition levels of crude fibre and enzyme preparation in diet were 4.741% and 0.241% respectively, the optimum feed conversion rate was 2.01. |
