Embodiment 1
[0028] The feed for growing and finishing pigs without soybean meal includes the following components in parts by weight:
[0029] Corn 50-80 parts, rapeseed meal 15-35 parts, bran 0.5-10, rice bran 1-8, stone powder 0.6-2, calcium hydrogen phosphate 0.2-1.2, salt 0.1-0.8, lysine 0.1-1, methionine 0.01 -0.15, threonine 0.01-0.4, tryptophan 0.01-0.1, valine 0.01-0.15, choline chloride 0.01-0.1, rapeseed meal special compound enzyme 0.02-0.15, fattening pig compound premix 0.1-1 . The enzyme activity of each component in the special compound enzyme for rapeseed meal is: phytase 5000-20000U / g, xylanase 5000-30000U / g, cellulase 5000-5000U / g, β-glucanase 2000-30000U / g, mannanase 500-5000U / g, pectinase 500-5000U / g, acid protease 2000-10000U / g, neutral protease 2000-10000U / g, alkaline protease 5000-30000U / g , Amylase 500-5000U / g.
[0030] The concrete steps of above-mentioned feed preparation are as follows:
[0031] 1) Pulverization: After pulverizing the corn, rapeseed meal, br...

[0043]
[0044] 2. Experimental design
[0045] The experiment adopted a single factor completely random design, with 6 experimental sample treatments, 5 repetitions for each treatment, and 1 simulator for each repetition. After the diet was sampled by quartering method, it was pulverized into 60 meshes with an experimental feed grinder, mixed thoroughly and stored at -20°C for later use.
[0046] 3. Test method
[0047] The test was carried out by the in vitro simulation method, and the experimental operations such as buffe...
Embodiment 3
[0056] 1. Experimental Animals and Diets
[0057] In the experiment, 240 Xinmei three-element fattening pigs with body weight of (41.78±1.93) kg were randomly divided into 4 groups according to the principle of similar body weight, with 6 replicates in each group and 10 pigs in each replicate (column). The test period is 23 days. The diet composition and nutrient levels are shown in Table 4.

[0059]
[0060] 2. Test method
[0061] The experiment adopted a 2×2 factorial design, and the main factors were dietary treatment and compound enzyme treatment. Dietary treatment: corn soybean meal-based diet or rapeseed meal-based diet. Compound enzyme treatment: general compound enzyme and special compound enzyme for rapeseed meal, see Table 5 for compound enzyme zymogram. During the test period, feed and water were provided ad libitum, and the feed intake an...
