(1) Arch ring: Take the coal block and crush it, add a little salt, mix it with rice soup, put it in the tank before feeding the pig, let the pig feed it, feed it once every 5 days until the pig does not like it. This ruled pig arch is very effective. (2) 窜 : 剪 剪 剪 : : : : : : : : : : : : : : : : : : : : : : : : Because the eyelashes are cut off, when the pig looks up and the ring is raised, the eyes will be stimulated by the wind, light, and dust, and they will feel the fear. (3) 啃 wall: For pigs who like to bite the wall, the general pig farmers do not think that it is caused by the imbalance of feed nutrition. It is often used by intimidation and sticking methods to stop it, but it does not work. In fact, the reason for the pig's wall is that the amount of salt in the feed is insufficient. The wall of the pig house is close to the ground. Because of the long-term excrement, there are more nitrates. The pig will find the salt that is lacking in the body with a sensitive sense of smell. Therefore, salt should be replenished in the feed in time. For 60-90 kg fattening pigs, the salt content in the diet should be 0.25%, and the breeding boar should be 0.35%. (4) Bite: Drive the original pigs out of the fence, then spray the liquor on the pigs that have just been bought and the pigs in the original store, and then put the pigs that have just been bought back into the bar, and then put them in the bar. The pigs that had been kept in the bar rushed back into the circle, and the pigs would not bite. (5) Phagage: For pigs with regular chickens and ducklings, a small amount of chicken feathers can be browned, ground into fine powder, rolled into a tube with paper, and then the fine powder is put into the tube and blown to the pig. In the nostrils, the pigs will not be upset when they see chickens and ducks.
