Feed additive by mixedly fermenting shrimp heads and vegetable feed proteins and processing method thereof
A feed additive and plant feed technology, which is applied in the field of feed additives and its processing using the mixed fermentation of shrimp head and plant feed protein, can solve the problem that the protein content of fermented soybean meal cannot reach the level of fish meal, and the lack of animal feed protein growth-promoting factors, technology Low production level and utilization rate, etc., to achieve the effect of low production cost, low production cost, rich and comprehensive nutrition

[0044] Example 1
[0045] The fresh shrimp heads are crushed, beaten with water, sieved and separated to separate the shrimp head semi-liquid thick slurry from the shrimp shells. After processing every 1000 kg of shrimp heads, about 1500-2000 kg of semi-liquid shrimp head thick slurry can be obtained. The shrimp shells are dried directly and used as the raw material of chitin and shrimp shell powder; 1000 kg of crushed soybean meal is mixed with 1000 to 1200 kg of shrimp head thick slurry, depending on the amount of shrimp head thick slurry and the degree of thickness, an additional 200 ~250 kg of water, make the total water content of the raw materials in the range of 40-60%, and initially stir evenly, then add 5 kg of Bacillus subtilis, 3 kg of feed yeast, and 5 kg of Lactobacillus delbrueckii. Stir and mix well. The best mixing is It is carried out in a feed mixer, and manual mixing can also be used when the processing volume is small; to start fermentation, the fermentation envi

[0047] The fresh shrimp heads are squeezed or crushed, pulped, sieved and separated to separate the shrimp head semi-liquid thick slurry from the shrimp shells. After each 1000 kg of shrimp heads are processed, about 1500 to 2000 kg of semi-liquid thick slurry can be obtained. Shrimp shells are dried directly and used as raw materials for chitin and shrimp shell powder; 1000-1200 kg of shrimp head thick slurry is added to 1000 kg of crushed soybean meal, depending on the amount of shrimp head thick slurry and the degree of thickness, another 200~ 250 kilograms of water, and initially mix well, then add 8 kilograms of Bacillus natto, 5 kilograms of feed yeast, 8 kilograms of Streptococcus thermophilus, stir and mix evenly, and mix in a feed mixer. It can also be processed when the amount is small Use manual mixing; start fermentation, the fermentation environment temperature must be above 20 degrees, if the environment temperature is low, certain heating measures s

[0049] The fresh shrimp heads are squeezed or crushed, pulped, sieved and separated to separate the semi-liquid thick slurry of shrimp heads from the shells. After processing each 1000 kilograms of shrimp heads, about 1500-2000 kilograms of semi-liquid thick slurry can be obtained. Shrimp shells are dried directly and used as raw materials for chitin and shrimp shell powder; 1000 kg of crushed peanut meal is mixed with 700-800 kg of shrimp head thick slurry, and 200 is added depending on the amount of shrimp head thick slurry and the thickness. ~300 kg of water, then add 10 kg of Bacillus subtilis, 5 kg of Candida tropicalis, and 8 kg of Lactobacillus delbrueckii, and mix it evenly, stir and mix well, and mix in a feed mixer. When the processing volume is small Manual mixing can also be used; start fermentation, the fermentation environment temperature should be above 20 degrees, if the environment temperature is low, certain heating measures should be taken, aera
