Blood meal processing method

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

First, the carrier blood meal simple processing method

1. Mix 1~2 times the amount of blood bran (rice bran or cake flour) with blood, stir evenly and spread it on the cement floor. Turn it on, and then dry it for 4-6 hours, then crush it. . Blood meal made of bran or rice bran contains 30% to 35% of crude protein, and blood meal made of cake flour contains 45% to 50% of crude protein. The amount of carrier blood meal should not exceed 5% in pig diet, and about 3% in chicken diet.

2, can be used to make powder into soybeans, the processing method is basically the same as above, but in the production, the blood bean powder should be made into a block, steamed for 20 minutes, after it is cooled, smashed into thin strips to dry, and then smashed. Blood bean powder contains about 47% crude protein. Feeding chicks with blood soy flour should not exceed 3% of the diet. Young chickens can be used instead of fishmeal. The feeding chickens can partially or completely replace the fishmeal.

Second, the processing method of dried blood meal

Pour the blood into the pot, add the quicklime equivalent to 1% to 1.5% of the blood volume, cook it to form a crunchy mass, remove the pellet and cut it into small pieces of 5-6 cm, and spread it on the concrete floor. It is dried to a tan color and then pulverized into a powder by a pulverizer to form a blood meal. This blood meal is usually used to feed broiler chickens, which usually account for 3% of the diet, and the laying hens account for 2% to 3% of the diet.

If 0.2% calcium propionate is added to the blood powder, and the pocket for the blood powder is soaked in a 2% aqueous solution of calcium propionate, and the blood powder is dried after drying, it can play a good anti-mildew effect.
