Example Embodiment

[0025] Example 1

[0026] Add 800 kg fish paste, 6-10 kg molasses, 0-60 kg pineapple peel juice, 250 g magnesium sulfate, 450 g potassium phosphate, 4000 g ammonium sulfate, 6 kg Bacillus subtilis, and 4 kg feed yeast into 1000 kg of crushed soybean meal. , 7 kg of Lactobacillus delbrueckii, when the amount of pineapple peel juice is large, the amount of molasses added is reduced appropriately, stir and mix evenly, and ferment in the fermentation tank for 65 to 76 hours. During the first 40 hours of fermentation, the center temperature of the pile should exceed 45. When the temperature is below ℃, cooling measures such as turning must be taken, and drying, crushing, inspection and packaging are carried out after fermentation.

Example Embodiment

[0027] Example 2

[0028] Add 900Kg of fish paste, 6-10Kg of molasses, 0-60Kg of pineapple peel juice, 250g of magnesium sulfate, 450g of potassium phosphate, 4000g of ammonium sulfate, 6kg of Bacillus subtilis, and 4kg of feed yeast into 1000kg of crushed soybean meal. , 7 kg of Lactobacillus delbrueckii, stir and mix well, ferment in the fermentation tank or directly piled for 40 to 48 hours, if the center temperature of the pile exceeds 45℃, cooling measures such as turning must be taken, and when the first fermentation stage is almost completed The fermentation raw materials are directly sealed and packaged. The method of sealed packaging is to directly put the fermentation raw materials into a feed packaging bag lined with a plastic bag and properly compact, vacuum and seal the packaging, and seal and seal to ensure the subsequent anaerobic fermentation environment. The raw materials are transported, During the storage process, the anaerobic fermentation of the second fermen...

[0029] Example 3

[0030] Add 800Kg fish paste, 6-10Kg molasses, 0-60Kg pineapple peel juice, 250g magnesium sulfate, 450g potassium phosphate, 4000g ammonium sulfate, 7kg Bacillus natto, and feed yeast 5 to 1000kg of crushed soybean meal. Kg, 8 kg of Streptococcus thermophilus, stir and mix well, ferment in the fermentation tank for 65-76 hours. During the first 40 hours of fermentation, if the temperature in the center of the pile exceeds 45℃, cooling measures such as turning must be taken. After the fermentation is completed Carry out drying, crushing, inspection and packaging.

Abstract

The invention discloses fish soluble feed protein and a processing method thereof. The processing method comprises the following steps of: mixing fish soluble and bean pulp, adding a strain into the mixture for solid-state fermentation, directly mixing the obtained product without drying and other raw materials in a formula and taking the mixed products as a feed for pigs, birds and cattle, or drying and crushing the obtained product to prepare the fish soluble feed protein used for protein raw materials in the feed industry and breeding industry after the fermentation is finished. The method has the advantages of simple process, low equipment investment and low cost; and the fish soluble feed protein is strong in fragrance and good in food attraction, improves protein content, is high in small peptide content and easy to digest and absorb, eliminates anti-nutritional factor in the bean pulp, is rich in various beneficial functional nutrient components such as probiotic and the like, plays active roles in improving weight gain and feed conversion rate, strengthening the immune function of organisms, improving production performance and the like, can greatly replace fish meal in livestock and poultry feeds and aquatic feeds, remarkably reduce feed cost, turn the fish soluble into the value from the waste, and is favorable for environmental protection as well as energy conservation and synergism.

Description

technical field [0001] The invention relates to a method for producing fermented feed protein by utilizing fish pulp, a by-product of fishmeal processing, and a processing method thereof. Background technique [0002] Fishmeal is an excellent protein feed and a strategic resource for the feed industry and aquaculture. The annual output of aquatic products in my country reaches more than 50 million tons, and the annual processing of fishmeal, which accounts for 30% of seafood, reaches 700,000 tons. The output of tilapia in my country ranks first in the world, and the main producing areas are Guangdong, Guizhou and Qiong. At present, tilapia is mainly processed into frozen fish fillets for export, and the processed leftover fish heads, fish steaks and viscera account for about 40-50% of the whole fish weight. More than %, tilapia leftovers contain a large amount of protein, fat, minerals and other substances, and have high utilization value. At present, the utilization of pro...
