Introduction to simple processing of blood meal

The blood of livestock and poultry is rich in protein and has high nutritional value. Through simple processing, a high-quality, high-protein feed, blood meal, can be produced. The specific practices are as follows:

1, drying. Put the collected blood of the livestock into the pot, cook it with fire, make it into a blood clot, then remove the formed blood clots, cut into 5-6 cm pieces, spread on the concrete floor and dry to tan. Then, it is pulverized into a powder by a pulverizer to form a blood meal. The blood meal prepared by this method can be fed into the feed of livestock and poultry at a ratio of 0.5% to 1%.

2. Carrier method. Use wheat bran, rice bran or defatted soy flour as a carrier, add it to the blood of fresh livestock and poultry in a ratio of 1:1, stir well, spread it on the concrete floor, dry it, and turn it frequently until it is dried, then crush it to get Carrier blood meal. The carrier blood powder can be fed in a ratio of 1% to 2%.

3. Fermentation method. Choose a non-toxic, harmless, beneficial microbe that can improve and maintain the nutritional value of blood and improve the palatability of blood meal, inoculate it into the waste blood of fresh livestock and poultry, promote its rapid growth and reproduction, increase the temperature, and thus kill or inhibit harmful The growth and development of microorganisms. The main process is: mixing the collected livestock blood with the porous carrier in a ratio of 1:1, adding 2%-3% of the meat, and fermenting at 38-39 ° C, the time should not be too long, the fermentation temperature Can not exceed 40 ° C. Then, it is dried, and when the water content falls below 13%, it can be pulverized and packaged. In this process, the added meat must be pure, can not contain any bacteria, the porous carrier is best to use wheat bran, which can increase the crude protein content of the blood meal, the crude fiber content is reduced, and the palatability is also good. This method does not require high temperature treatment, and the degree of damage to nutrients is small. The quality of blood powder produced is high, there is no astringency, and livestock and poultry are fond of eating.

Collection and processing of blood of livestock and poultry with infectious diseases, parasitic diseases, poisoning or causes of death is prohibited.
