Embodiment 1
[0026] The present embodiment provides the preparation method of the laying hen feed that is rich in collagen protein, comprises steps as follows:
[0027] 1) primary fermentation: get 8kg of St. chinensis, 12kg of Houttuynia cordata, 5kg of dandelion, and 65kg of soybean meal after mixing, add 35% of its total weight of xylitol, 0.2% of copper gluconate, and 0.03% of fermenting bacteria. Constant temperature fermentation at 20°C for 3 days to obtain a primary fermentation product;
[0028] 2) Secondary fermentation: add 7kg of laver and 5kg of white fungus to the primary fermentation product, and ferment at a constant temperature of 34°C for 2 days to obtain the secondary fermentation product;
[0029] 3) Extraction: take 18kg of pigskin, 1.5kg of fish maw, and 1.3kg of mandarin fish skin and mix them, add an organic acid solution with a mass concentration of 40% twice the total weight, and extract by microwave for 15min at a temperature of 83°C, and then Lower the temperatu...
Embodiment 2
[0038] The present embodiment provides the preparation method of the laying hen feed that is rich in collagen protein, comprises steps as follows:
[0039] 1) Primary fermentation: get 5kg of St. chinensis, 6kg of Houttuynia cordata, 3kg of dandelion, and 50kg of soybean meal after mixing, add 30% of its total weight of xylitol, 0.1% of copper gluconate, and 0.02% of fermenting bacteria. Constant temperature fermentation at 15°C for 2 days to obtain a primary fermentation product;
[0040] 2) Secondary fermentation: add 3kg of laver and 2kg of white fungus to the primary fermentation product, and ferment at a constant temperature of 28°C for 1 day to obtain the secondary fermentation product;
[0041] 3) Extraction: Take 15kg of pigskin, 1.2kg of fish maw, and 1.2kg of mandarin fish skin, mix them, add 1-2 times the total weight of an organic acid solution with a mass concentration of 30-40%, and microwave at a temperature of 75°C Extract for 10 minutes, then lower the temper...
