Feeding pigs with chicken manure is a new way of developing feed sources, with less investment, good efficiency and simplicity. However, chicken manure contains harmful substances and parasite eggs (coccidial, nematode), fleas, cockroaches, and intestinal mucosal shedding cells, as well as undigested fibers, crude protein, and trace element microorganisms, which need to be treated before they are fed to pigs. .
Fermentation
The natural fermentation method mixes fresh chicken manure and wheat bran in a ratio of 3:2 or crushed barley in a ratio of 1:1. The water content is controlled at about 50%, and the fermentation is carried out in a silo and the temperature is maintained above 5°C. 20-40 days after the open cellar feeding.
Pots and jars fermented to remove chicken droppings feathers and other debris, air dry smashed, add water to the hands to form a group, fingers without dripping is appropriate, mixed with washed green fodder, into the cylinder compaction, surface sprinkled with 2 cm The bran or rice bran is sealed with a plastic membrane and placed in a room or in a cool place. It is maintained at a temperature of about 20°C and fermented for 10-15 days.
Accumulation Fermentation Pour the collected chicken manure into a cylinder and stir it with bubbling. After the sedimentation, remove the impurities from the upper layer and the lower sediment, take the middle layer of pure chicken manure and drain the water. Add 150-200g of yeast tablets, 150-200 tablets of sugar tablets, and 50-60 tablets of oxytetracycline per 100kg of chicken manure, stack and ferment for 5-6 hours, and add 20% of the pig diet.
The plastic bag is fermented and the chicken manure is dried till it is 70% dry. Every 10 kilograms of chicken manure is blended with 1-2 kilograms of bran or rice bran. Stir it evenly and put into a non-toxic plastic bag to seal the fermentation. Ferment in the summer for 1 day. Spring and autumn fermentation. Days, the standard of fermentation is good to smell the smell of lees. Fermented feces can be blended with 60%-75% of other feeds to pigs. For long-term storage, the fermented manure can be dried (less than 7% moisture), bagged and later used to feed pigs.
Distiller's grain fermentation Add appropriate amount of bran in fresh chicken manure, add 10% distillers grains and 10% water, mix well and ferment in fermentation tank or tank for 10-20 hours, then steam sterilization with 100°C, For feed.
The 9FJ-500IA chicken manure reconstitution feed fermenter developed by China's mechanical fermentation can be adjusted according to the need. The purpose of fermentation can be reached within 3-4 hours. Fermented chicken manure presents a tan, loose, sweet odor suitable for medium and small-scale chicken farms or feed mill applications.
Drying method
Naturally dried chicken manure is collected alone or in combination with a certain proportion of rice bran or wheat bran (20%-30%), mixed well and put in a clean place, dried and deodorized by natural sunlight, dried and sieved to remove feathers. , Shisha and other debris after crushed, placed in a dry place for use, feeding can be added in accordance with the aforementioned ratio.
Drying method Add 10% industrial ferrous sulfate to fresh chicken manure, mix well and dry at a temperature of 120°C-160°C. When the moisture content drops below 10%, feed it.
High-temperature fast-drying Fresh chicken manure is heated in a non-stop dehydrating dryer. At high temperatures of 500°C to 550°C, moisture can be reduced to below 13% in a short period of time. This drying device mainly includes a heat generator, a combustion chamber, a drying cylinder, a cyclone separator, an automatic controller, and the like.
Mechanical drying uses drying machinery and equipment for drying. Most of them are heated by a power supply. The temperature is heated at 70° C. for 12 hours, at 140° C. for 1 hour, and at 180° C. for 30 minutes for feed.
