There is a new way to use chicken manure as feed.

In the past, when processing chicken manure as feed, the natural drying method was generally used, which was not only unsanitary, but also easy to lose nutrients. At present, some new processing methods have emerged:

Formaldehyde-sulfuric acid-urea treatment. Spread out the fresh chicken manure, add 0.5% formalin and stack it for 24 hours; then add 0.1% sulfuric acid, stir evenly, and then stack for 24 hours; finally turn the pile, add 3% Mel 5% urea, stir and oxidize for 24 hours, stack for 24 hours and then dry in bulk, and then process and crush it for feed. The chicken manure treated by this method is non-toxic, colorless and tasteless, and pigs love to eat it, and the optimum proportion in the diet is 10%, 15%.

Phosphoric acid-propionic acid-acetic acid treatment method. Add chemicals, including 1% calcium phosphate or phosphoric acid, 80% propionic acid, 20% acetic acid, according to 0.25% Mel 0.5% of the total chicken manure, stack for 5-14 days, and use after processing and crushing. This method is convenient and practical and has no environmental pollution.

Microbial fermentation. Aspergillus oryzae and other strains were used in this method, and the solid raw meal fermentation process was used to treat chicken manure. The chicken manure regenerated feed produced by this method has special flavor, rich nutrition and easy absorption, the crude protein is more than 29%, and the essential amino acids are increased more than 7 times, which greatly improves the biological value of chicken manure.

Mixed silage. Cellar storage, bag storage and stacking can be used. Mix chicken dung with chopped green corn straw evenly, chicken manure accounts for 30%, corn straw accounts for 70%. The operation method is similar to the ordinary silage, filling while compacting, in order to reduce the residual air, after filling, sealed strictly, after 30 days, open the top of the pit, smell obvious wine flavor, indicating that the silage is successful and can be used layer by layer. The chicken manure treated by silage fermentation has sour, sweet, fragrant and alcoholic taste, good palatability, fast daily gain, smooth fur, strong physique, strong resistance and reduced incidence.
