Embodiment 1
[0030] Dry the milk thistle meal and smash it through a sieve. Take 700 grams of milk thistle meal: 200 grams of bran and 100 grams of corn flour to prepare a mixed powder. Based on the dry weight of the above mixed powder, add 5 grams of glucose, 10 grams of urea, and 4 Grams of potassium dihydrogen phosphate are mixed uniformly to make a fermentation medium, the water content is adjusted to 50%, the pH is natural, and it is autoclaved at 121 ℃ for 15 min. Then inoculate a mixed bacterial solution of 5% of the dry weight of the fermentation medium, the mixed bacterial species and the ratio: Aspergillus niger: Candida tropicalis = 1:1, 28 ℃ fermentation for 48 hours, 45 ℃ drying to obtain 935 grams of protein feed. The crude protein content of the protein feed is 37%.
Embodiment 2
[0032] Dry the milk thistle meal and smash it through a sieve. Take 800 g milk thistle meal: 150 g bran: 50 g corn flour to prepare a mixed powder. Based on the dry weight of the above mixed powder, add 10 g glucose, 15 g urea, and 5 Grams of potassium dihydrogen phosphate are mixed uniformly to make a fermentation medium, the water content is adjusted to 60%, the pH is natural, and it is autoclaved at 121 ℃ for 15 min. Then inoculate a mixed bacterial solution of 10% of the dry weight of the fermentation medium, and the mixed bacterial species and ratio: Aspergillus niger: Candida tropicalis=1:1, fermented at 30 ℃ for 87 h, dried at 50 ℃ to obtain 911 grams of protein feed . The crude protein content of the protein feed is 42%.
Embodiment 3
[0034] Dry the milk thistle meal and smash it through a sieve. Take 900 g milk thistle meal: 50 g bran: 50 g corn flour to prepare a mixed powder. Based on the dry weight of the above mixed powder, add 20 g glucose, 20 g urea, and 8 Grams of potassium dihydrogen phosphate are mixed uniformly to make a fermentation medium, the water content is adjusted to 70%, the pH is natural, and it is autoclaved at 121 ℃ for 15 min. Then inoculate a mixture of 15% of the dry weight of the fermentation medium, and the mixed strain and ratio: Aspergillus niger: Candida tropicalis=1:1, fermented at 32 ℃ for 120 h, dried at 65 ℃ to obtain 923 grams of protein feed . The crude protein content of the protein feed is 39%.
