In order to verify the application effect of the feed prepared by the invention on the production performance of broiler chickens, 280 healthy 1-day-old Ross 308 commercial broiler chickens (40 for later use) are selected and randomly divided into 3 treatment groups for feeding test, and each treatment is repeated for 8 times. Treatment group 1: in the control group, the broilers are fed by conventional ration (NRC recommended nutrition level) without adding any vitamin; the treatment group 2 is the treatment group 1, and is added with the uncoated compound multi-vitamin premix feed which is the same as the components in the example 1, and the addition amount is 300 g/ton; treatment group 3 was treated with the coating composite multi-vitamin premix feed prepared in example 1 in an amount of 300 g/ton based on treatment group 1. The above 3 groups are fed in stages of 1-42 d. Feed intake was recorded daily and weighed at 42 days. Calculating daily feed intake, daily gain and material weight ratio. The experimental data were counted using SAS 9.3 software, the differences between treatments were performed using one-way ANOVA, and multiple comparisons of each measured data were performed using the Duncan method with a significance level P < 0.05. Specific results are shown in tables 1 and 2.
