How to feed pigs with cottonseed cake
Cottonseed cake is a by-product of cottonseed oil extraction, generally containing 30% to 40% of crude protein, but because it contains a certain amount of toxic free gossypol, its use is limited. If a large number of pigs are used for a long period of time, it will cause poisoning, so it must be detoxified and limited to feed the pigs. In pig breeding practices, the following methods can be used to reduce the toxicity of cottonseed cakes and thus increase their feed value. Water boiling method The crushed cottonseed cake is soaked in warm water and soaked for 8 hours to 12 hours. The soaking solution is drained, and the appropriate amount of fresh water is added (in order to submerge the cottonseed cake), and boiled for 1 hour while stirring while stirring. After cooling, Can feed. The ferrous sulfate solution soaking method will be used to soak the cotton seed cake with 1% ferrous sulfate solution for 1 day and night, stir several times in the middle, soak the soaking solution after soaking, and feed directly. Alkaline water soaking method is soaked with 2.5% plant ash or 5% lime water or baking soda solution for 24 hours (1 day and night), and then the soaking solution is removed, filtered with fresh water three times, and then fed. Controlling the amount of feed for finishing pigs should not exceed 400 grams per day, pregnant sows should not exceed 250 grams per day (in the case of sows pre- and postpartum half-monthly feeding), newly weaned piglets do not exceed 100 grams per day, and are generally fed 1 After one month, stop feeding for 1 month or half a month for half a month. Feeding Green Forage Green feed is rich in vitamins and more water, especially carotenoids and vitamin C, and has a laxative effect, can reduce the toxic effects, prevent constipation and improve nutritional status.
