白菜是很常见的蔬菜，人们除了自己食用之外，也常常拿来喂猪。白菜本身没有毒素，作为青饲料猪也很爱吃，但如果处理不当，也会引起中毒。
Chinese cabbage is a very common vegetable, and people often feed it to pigs besides themselves. Chinese cabbage has no toxin, and it is also very popular as a green fodder, but if it is not handled properly, it will also cause poisoning.
因为白菜中含有硝酸盐，人们通常会煮熟后饲喂，闷煮的时间过长时，就会还原成有毒性的亚硝酸盐。猪吃了会产生呼吸困难、走路不稳、口吐白沫、体温下降等症状。含有毒素的白菜，半小时左右就会出现中毒症状。如果不能及时抢救甚至会痉挛而死。所以养猪户在用白菜喂猪时应注意:
Because cabbage contains nitrate, people usually cook it and feed it for a long time. When it is overcooked, it will be reduced to toxic nitrite. Pigs will suffer from dyspnea, unstable walking, foaming at the mouth and falling body temperature. Chinese cabbage containing toxins will appear toxic symptoms for about half an hour. If you can't rescue it in time, it will even die in spasm. So the pig farmers should pay attention to feeding the pig in the use of Chinese cabbage.
1、在煮白菜时不要焖着煮，应该不盖盖子快煮，同时不断搅拌，尤其是量大的情况下，要经常搅拌，煮后立刻捞出放凉，喂多少煮多少。

2、可以喂一些生白菜，但量不宜过大，以免拉稀。
2, you can feed some raw cabbage, but the volume should not be too large to avoid diarrhea.
3、不要堆积过久，避免腐烂，菜叶如果腐烂，则不能用来喂猪。
3, do not accumulate too long to avoid decay. If the leaves are rotten, they can not be used to feed pigs.
