At present, pig raising and feeding will be used together with pig raising equipment. Feeding pigs should be reasonably configured with feed, and can not be eaten randomly, which will cause certain harm. Here are three inappropriate ways to feed pigs.
1. It is not suitable to feed the pig with the green material and the fine material
To achieve the goal of rapid fattening, the green material must be matched with 40% of the refined material. The refined material is the general pig's full price material, and 10% glutinous rice bran can be added into the feed. In the feeding process, we usually feed the concentrate first, then the green feed, four times a day. It is better to eat up within half an hour each time. In this way, we can gain 800 grams per day.
2. It is not suitable to add water to feed pig with pellet feed
When many farmers feed pigs with granular feed, they still add water to make porridge, and some even use boiled water to wash the feed or boil it in the pot, which can not only reflect the superiority of granular feed, but also destroy the nutrition of granular feed. The pellet feed is made by pressing the full value compound powder through the pellet feed machine. Compared with the powder, it has good palatability, high digestibility, low incidence rate, large intake, fast growth rate of home and high feed reward.
3. Pumpkin leaves should not be fed to pigs
Pumpkin leaf poisoning is actually nitrite poisoning. If the weather is sunny for a long time, and it rains suddenly, pumpkin rattan leaf absorbs a lot of nitrate and nitrite from the soil, but it has not been digested and utilized yet. At this time, it is easy to be poisoned if it is cut to feed pigs. Therefore, pumpkin leaf is not suitable to feed pigs generally.
