The feed required for ecological pig raising is complete compound feed. The better food chain model is that chicken manure is fed to pigs, and biogas produced by pig manure fermentation is used as energy for pig farms, biogas residue is used for fish farming, and fish pond sludge is used for fertilizer production.
When carrying out family ecological pig raising, we should first pay attention to selecting excellent pig breeds, especially those with strong resistance, such as hybrid pigs; Secondly, we should pay attention to the complete value of feed to ensure that pigs can get comprehensive and sufficient nutrition from feed; Third, do a good job in disease prevention and treatment, reduce pig diseases and improve productivity; Fourth, do a good job in the environmental sanitation of the pig house and control the temperature and humidity to avoid affecting the productivity of pigs due to environmental factors.
