Chicken dung has low cost and high nutritional value. It was determined that naturally dried chicken dung, containing about 26% crude protein, contains almost all essential amino acids, with 0.51% for lysine and 1.27% for methionine and cystine. At the same time contains a large number of calcium and phosphorus, potassium, sodium, magnesium, iron, copper, manganese, zinc and other constant and trace mineral elements, especially caged egg chicken manure, are higher than the grain seed feed. Since most of the crude protein contained is non-protein nitrogen and can be used by ruminant livestock, it is a good feed for fattening beef cattle. However, chicken excrement is poor in palatability, and may contain certain parasite eggs and pathogenic microorganisms, which are harmful to the bovine body. Therefore, fermentation must be performed before feeding. Fermentation method The chicken feces and net feathers were dried and beaten. Each 100 kg was uniformly mixed with 40 kg bran or 20 kg bran, 20 kg distillers grains, 0.8 kg salt, water and wet, and the water content was about 55%-65%. Then layered into the cylinder or cement pool, layer compaction, until 20 cm above the pool surface, covering the plastic film seal, summer and autumn air temperature 15-20 days, winter indoor or plastic greenhouse 20-30 days Feeding. Fermented chicken droppings are yellow and slightly acidic. If mildew occurs, you cannot drink it. Fermentation methods: Fermented chicken droppings 40%, corn 45%, bran 12%, salt 1.5%, mineral additives 1%, sodium bicarbonate 0.5% mixed concentrates, feed dry matter 60%-70% and ammonia Combine wheat straw or silage with an additional 200 mg of rumen per head per day. Within 2 years of age, over 300 kilograms of fattened cattle, daily gain of more than 1.2 kilograms. The amount of chicken feces started to increase from small to large and gradually increased, and fed at 2 weeks.
