Sweet potato "change" feed saves cost and increases efficiency

First, root tuber: each unit of fresh potato is equivalent to 0.3 units of corn, which is an excellent succulent feed and a good energy feed. All kinds of livestock like to eat, so it is most suitable to feed pigs. The method is to cook it and feed it to pigs according to 15-20 kg cooked potato mixed with 1 kg concentrated feed (crude protein ≥ 34%). The effect is the same as that of full-price formula feed, but the feed cost is much lower than that of formula feed. The effect of feeding sweet potato alone or raw is not good. Those with root rot or black spot should be dug and buried deep, and human and animal consumption is strictly prohibited.

Second, dried sweet potato (powder): put the washed slices of sweet potato into boiling water and blanch it, pick it up and dry it, and crush it into sweet potato powder. Each unit of dried sweet potato (flour) is equivalent to 0.9 units of corn. It can be used as energy feed to feed all kinds of livestock and poultry. Single feeding doesn't work well.

Third, sweet potato powder residue: sweet potato is often used to extract starch, and the residue after extracting starch is sweet potato powder residue. Its nutrient content is equivalent to 0.17 corn units. The water content of sweet potato powder is about 76%, so it is easy to rancidity, so it should be fed fresh in time. Daily feed: 10kg for dairy cows and 3kg for pigs. When feeding pigs, you should pay attention to supplement protein feed and cook it, and mix it with other feed. The amount of feed shall not exceed 30% of the total feed (all in terms of dry matter). If the fresh food is in danger of rancidity, the sweet potato powder can be evenly mixed with an appropriate amount of bran, the water content can be adjusted to 70%, silage alone or with other green fodder and then fed to livestock.

Sweet potato vines: sweet potato vines are tender, juicy, nutritious and palatable. Each unit of sweet potato vine is equivalent to 0.05 units of corn. Feeding method: first, fresh feeding, beating or chopping and raw feeding. Feed 30kg / cow / month, 3kg / pig / pig and 0.5kg / goose / day. The second is feeding after silage. The method is to cut the sweet potato vines before the frost, cut into short sections less than 3 cm, dry the moisture to about 70%, pack it into a cement pool or thick plastic bag layer by layer, then seal it layer by layer, and then open the cellar after 20 to 30 days.
