Sweet potatoes turn into feed, saving costs and increasing efficiency at the same time

1. Tuberous roots: each unit of fresh sweet potato is equivalent to 0.3 corn units. It is an excellent succulent feed and also a very good energy feed. All kinds of livestock like to eat it, and it is most suitable for feeding meat pigs. The method is to boil it, mix 15-20 kg of cooked sweet potato with 1 kg of concentrated feed (crude protein >= 34%), stir evenly and feed to meat pigs. The effect is the same as a complete compound feed, but the feed cost is much lower than compound feed. Feeding sweet potato alone or feeding it raw has a poor effect. Tuberous roots that are rotten or have black spot disease should be buried deep in a pit, and it is strictly forbidden for humans and livestock to eat them

2. Dried sweet potato (powder): wash sweet potatoes, slice them, blanch them in boiling water, take them out and dry them in the sun to make dried sweet potato; crush them to make 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 make compound feed for feeding all kinds of livestock and poultry. Feeding it alone has a poor effect.

3. Sweet potato starch residue: sweet potatoes are often used to extract starch, and the residue after starch extraction is sweet potato starch residue. Its nutrient content is equivalent to 0.17 corn units. The moisture content of sweet potato starch residue is about 76%, so it spoils very easily and should be fed fresh in time. Daily feeding amount: dairy cows 10-30 kg, pigs 3-10 kg. When feeding pigs, attention should be paid to supplementing protein feed and boiling it, and mixing it with other feed. The feeding amount should not exceed 30% of the total feed amount (all calculated on a dry matter basis). If it cannot be fed all at once when fresh and there is a risk of spoilage, mix an appropriate amount of bran into the sweet potato starch residue evenly, adjust the moisture content to 70%, and ensile it alone or together with other green feed before feeding it to livestock.

4. Sweet potato vines: sweet potato vines are tender, succulent, nutritious and highly palatable. Each unit of sweet potato vines is equivalent to 0.05 corn units. Feeding methods: first, feed fresh, either after pulping or chopping and feeding raw. For dairy cows, use 30-40 kg per head per month; for pigs, 3-15 kg per head; for geese, 0.5-2 kg per bird per day. Second, feed after ensiling. The method is to cut the sweet potato vines before frost, cut them into short pieces of less than 3 cm, dry them until the moisture content is about 70%, put them into a cement pit or thick plastic bag, compact them layer by layer, and seal them. After 20-30 days, the pit can be opened for use.
