In recent years, some farms (households) have adopted mixed breeding of livestock and poultry, and used a certain kind of livestock and poultry to feed another livestock and poultry. However, it must be noted that there is a great danger in such a food chain. Because the composition of livestock and poultry manure is relatively complex, it contains many components that are unfavorable to the health of livestock and poultry, and can easily cause cross-infection of livestock and poultry or outbreaks of infectious diseases. Therefore, the following treatment must be taken when feeding livestock and poultry manure: 1. Livestock manure used as feed must be fermented and must not be directly fed. 2. When feeding livestock and poultry with fermented livestock and poultry manure, add certain antibiotics such as oxytetracycline. 3. Feeding livestock and poultry with fermented manure should be gradually increased from less to more, and the amount should not exceed 40%. 4, due to the poor palatability of fermented manure, can add some seasonings when feeding, such as salt, saccharin and so on. 5. Always feed green feed. 6, to periodically deworming, chickens once a month, pigs once a month. 7. Feeding of livestock and poultry excrement must be stopped before the slaughter.
