Method of using sweet potato as feed
1. Root: Each unit of fresh potatoes is equivalent to 0.3 corn units. It is an excellent succulent feed, and it is also a good energy feed. All kinds of domestic animals like to eat, and it is best to feed pigs. Method is to cook it, according to 15-20 kilograms of cooked potato mixed with 1 kilogram of concentrated feed (crude protein ≥ 34%) to stir and feed the pig, the effect is the same as the full-price compound feed, but the feed cost is much lower than the compound feed. It is not effective to feed sweet potatoes or sweet potatoes. Roots rot or black spot should be digging deeply buried, it is strictly forbidden for human and animal consumption. Second, sweet potato dry (powder): The sweet potato washed slices put in boiling water boiled, picked up dried dried sweet potatoes, the crush is the sweet potato powder. Each unit of dried sweet potato (powder) is equivalent to 0.9 corn units. It can be used as energy feed to produce compound feeds for various livestock and poultry. Single feeding effect is not good. Third, sweet potato powder slag: sweet potatoes are commonly used to extract starch, slag after the extraction of starch is sweet potato powder slag. Its nutrient content is about 0.17 corn units. The moisture content of sweet potato powder slag is about 76%, so it is easily rancid and should be fed fresh in time. The amount of daily feeding: cows 10-30 kg, pigs 3-10 kg. When feeding pigs, care should be taken to supplement protein feeds and cook them, and feed them with other feeds. Feed no more than 30% of the total feed (based on dry matter). If there is no risk of rancidity when the fresh food is fed, the amount of bran in the sweet potato powder slag can be evenly mixed, and the water content can be adjusted to 70%, and the animal can be fed alone or in silage with other green feed. 4. Sweet potato vines: Sweet potato vines are tender, juicy, nutritious, and palatable. Each unit of sweet potato vine is equivalent to 0.05 corn units. Use methods: First, fresh feed, beating or chopped raw feed. Feeding cows each month uses 30-40 kg/head, 3-15 kg/head for pigs, and 0.5-2 kg/day for geese. The second is feeding after silage. The method is to cut the sweet potato vine before the frost, cut into short cuts of 3 cm or less, dry the water to about 70%, and seal it in the cement pool or thick plastic bag after layer-by-layer compaction. It can be opened after 20-30 days. Cellar use.
