Feeding pigs with chicken manure is a source of feed. It is a good way to use biofermentation and sterilization. It has less investment, good efficiency, and is simple and easy to implement. However, chicken manure contains harmful substances and parasite eggs (coccidial, nematode), faecal olfactory hormones, quinones, purines, cells shed by the intestinal mucosa, fibers that have not been digested, crude protein and trace elements, and invisible to the naked eye. Microorganisms need to be treated before they can be fed to pigs.

Treatment method: 1. Stacking fermentation. Fresh chicken droppings are air-dried until 70% dry, stacked squares are set up, covered with plastic film, pressed well, kept warm for 4-8 days so that the temperature reaches 75-80°C and remains for 48-96 hours to kill the chicken droppings. The pathogenic microorganisms such as bacteria, parasite eggs, and mycoplasma, etc., are then opened to air, bagged and stored, and both are well preserved and easily handled.

2. Feed directly to pigs. According to experiments, each pig can feed 1.5 kilograms of fresh chicken manure daily, plus 1 kilogram of hay and 0.5 kilograms of corn. In order to prevent cross-infection of pig diseases and chicken diseases, regular disinfectant powders (sodium hypochlorite or potassium permanganate) should be fed to kill microorganisms in chicken manure.

3. Thermal spray disinfection. When the chicken dung can be dried to semi-dry (moisture content 40%) by a dryer, special special bacteria for fermentation are mixed and fermented for 5-6 days.

Chicken manure is the best for chicken manure. It is both dry and clean. It eliminates the hassle of drying and directly incorporates full-priced ingredients. Mixing and feeding pigs works best.

Matters needing attention: First, we should pay attention to disinfection, cut off the source of infection, remove odors. Deodorizers, lactic acid bacteria, zeolite poisons and the like can be added. Secondly, pigs should stop feeding chicken droppings 14 days before slaughter, feeding green and green feeds and aromatic feeds, so that the pork will not have the specific taste left over from chicken droppings.

The first addition of chicken manure should be mixed with 70% compound feed, and then gradually increase the amount of chicken manure to reduce the amount of compound feed, to prevent a large amount of increase, so that pigs do not adapt to food and refuse to affect the increase in weight.
