Method for fermenting pig's blood into protein feed

Pig blood contains higher protein. After the slaughter of animals, the waste blood is fermented with a goldfish feed, which is a nutritious animal protein feed. Feeding animals to feed both nutrients and feed costs can be described as a double benefit.

Fresh pork blood (can be stored in fresh citric acid first) and wheat bran (rice bran) in a certain proportion, and then mixed with 1 gold and golden baby type 2 starter (which can be diluted with 5 times rice bran), after fermentation The dried feed has crude protein up to 45 and crude protein digestibility can reach over 90%. The method of fermentation of pig blood into feed is:

The pig's blood protein content is very high and should not be fermented separately. It should be mixed with energy feeds (such as cornmeal, wheat bran, etc.) and generally added in corn flour at a ratio of 30% to 40% (ie corn flour: blood meal = 70%: 30 %--60%: 40%). After adding well-mixed ingredients, add the golden bacon feed starter (first diluted with 5 times rice bran) according to one-thousandth to two-tenths of the total amount of feed. Mix well with the material. Depending on the situation, add water and mix well. The moisture content of the material is generally controlled at about 65%. The judgement method is: grab the fermented material tightly and grab a hand. The watermark can be seen through the fingers but not dripping. It is advisable to loosen the floor and release it. If the juice can be squeezed out and the floor does not spread out, the moisture content is too high, too dry and too wet, and it should be adjusted. After the material is adjusted, it is immediately loaded into pots, jars, pools, plastic bags, and other containers. It is sealed and fermented at natural temperatures for 2-3 days. It can be fed when it is fragrant, sweet, and alcoholic. When large-scale fermentation can be directly stacked in a clean concrete floor or fermentation tank, sealed plastic film can be sealed and fermented.

A boilersuit is a one-piece garment with full-length sleeves and legs like a jumpsuit, but usually less tight-fitting. Its main feature is that it has no gap between jacket and trousers or between lapels, and no loose jacket tails. It often has a long thin pocket down the outside of the right thigh to hold long tools. It usually has a front fastening extending the whole length of the front of the body up to the throat, with no lapels. It may be fastened with buttons, a zip, velcro, or snap fasteners. Boilersuits with an attached hood are available.
