Don't change materials too quickly. Feeding pigs used to clinker, if suddenly changed to feeding raw materials, can easily lead to diarrhea due to indigestion, because the pig's digestive function is not suitable for unexpected raw materials. Therefore, it should be gradual and gradual, can be changed every day about 1 / 4 of the raw materials, the implementation of raw and cooked mixed feeding, for four or five consecutive days to complete the reloading process.
Second, do not engage in the same way. Not all feeds are fed properly. Soybeans and bean cake contain toxic substances such as saponins, antitrypsin and hemagglutinin. High-temperature treatment not only destroys these toxins, but also facilitates the digestion and absorption of nutrients. The cooked sweet potato has good palatability after cooking and has high digestion and absorption rate.
Third, do not use irrigation feeding method. Many peasant households use raw materials to feed their pigs and use soup to fill their bellies. The raw materials are overloaded with water and the pigs are hungry soon after they are full. In addition, because the stomach juice is diluted after the pig eats, it affects the digestion and absorption, resulting in a waste of feed. Therefore, in order to change the wet mix to be more scientific, the ratio of feed to water of the wet mix is ​​1:1, which is generally 1 hour before summer feed, and 2 hours before winter feed.
