Example Embodiment
[0030] Example 1
[0031] Weigh 45 kg of corn stalks, 11 kg of bran, 8 kg of corn, 8 kg of secondary meal, 12 kg of soybean meal, and 16 kg of rapeseed meal to form a dry material. Among them, the corn stalks are crushed to a particle size of 300 mesh by a multi-stage cyclone mill; according to the dry material and water 1 :0.5% by weight, mix the above-mentioned dry material with water thoroughly and stir evenly, autoclave at 100°C for 10 minutes; inoculate 15% activated Pediococcus pentosaceus and 5% activated black mold after sterilization , Add 0.5 FPU / g cellulase at the same time, after stirring evenly, put it into a microbial breathing bag with a one-way exhaust valve, carry out solid-state fermentation at 28°C, fermentation time 72h; after fermentation, the finished straw feed is obtained. The feed has obvious sour flavor. The lactic acid content of the feed is 1.3% of the total weight of the feed measured by the conventional determination method in the feed field, and the...

[0032] Example 2
[0033] Weigh 40 kg of corn stalks, 10 kg of bran, 12 kg of corn, 10 kg of secondary meal, 10 kg of soybean meal, and 18 kg of rapeseed meal to form a dry material. Among them, the above-mentioned corn stalks are pulverized to a particle size of 300 mesh by a multistage cyclone mill; :0.5% by weight, mix the above dry material and water thoroughly and stir evenly, autoclave at 112°C for 10 minutes; inoculate 30% activated Pediococcus pentosaceus and 10% activated Bacillus subtilis after sterilization. Bacillus, add 2FPU / g cellulase at the same time, stir it evenly, put it into a microbial breathing bag with a one-way exhaust valve, carry out solid-state fermentation at 35°C, fermentation time 48h; after fermentation, a straw feed product is obtained. The feed has obvious sour flavor. The lactic acid content of the feed is 2.2% of the total weight of the feed measured by the conventional determination method in the feed field, and the number of beneficial viable ...

[0034] Example 3
[0035] Weigh 35kg of corn stalks, 13kg of bran, 12kg of corn, 10kg of secondary meal, 12kg of soybean meal, and 18kg of rapeseed meal to form a dry material. Among them, the above-mentioned corn stalks are crushed to a particle size of 200 mesh by a multistage cyclone mill; :1. Mix the above dry material with water thoroughly and stir evenly, autoclave at 112°C for 10 minutes; inoculate 20% activated Pediococcus pentosaceus and 5% activated Aspergillus oryzae after sterilization , Add 1.5 FPU / g cellulase at the same time, after stirring evenly, put it into a microbial breathing bag with a one-way exhaust valve, carry out solid-state fermentation at 40°C, fermentation time 48h; after fermentation, the straw feed product is obtained. The feed has obvious sour flavor. The lactic acid content of the feed is 2.1% of the total weight of the feed measured by the conventional determination method in the feed field, and the number of beneficial viable bacteria is 3×10 9...
