Why do pigs suffer from such problems as arch circle, wall collapse, eating pig manure, skipping bars, irritability and slow growth? This is caused by the lack of certain nutrients because pigs need more than 30 nutrients during their growth. If the feed can not meet, the pig will appear the above symptoms. The real reason why pigs bite wall studs is the lack of salt in the feed. Pigments in the walls of the pig house show more nitrate due to long-term accumulation of excreta. Pigs will find and ingest spontaneously with sensitive olfaction to supplement the body's lack of salt. The dietary salt content of finishing pigs weighing 60-90 kilograms should reach 0.25%, and the salt content of breeding boar should reach 0.35%.
