We used to cook sweet potato vines to feed pigs, which was hard and the feeding effect was not good. There are also sweet potato vines that are dried and stored for pigs. Leading to serious abandonment of nutrition.
Today, Bian Xiao shared a new fermentation technology of feeding pigs with compound probiotics and salt. The consumption of fermented sweet potato vines by pigs is more than 30% higher than that by direct cooking.

Specific methods: After the fresh sweet potato vine is crushed, add 1 package (500g, the market price is around 25 yuan) of "99 multifunctional feed starter", add 3kg of salt, 100kg of dry corn flour or 300kg of crushed fresh sweet potato (it is especially recommended to join this one for fermentation, which is more nutritious) and mix well.
Chop sweet potato vines with a pig vegetable machine.
After fermentation, the crude fiber which is difficult to use in rattan powder is reduced, and the toxin has been removed, thus becoming a high-quality feed with rich nutrition, sweet smell and good palatability. When fattening pigs are fed, they are gradually added according to the ratio of fermented sweet potato vine 15%-50%, and mixed with pig complete feed or self-made feed. Sows can also be fed, about 50% in reserve, empty pregnancy and early pregnancy, and about 15% in late pregnancy and lactation.
When the dosage exceeds 20%, it is suggested to supplement the pig premix properly. The reference formula of fermented sweet potato vine can be used for free-range farmers to raise fattening pigs (for example, more than 50 kg):
1. Fermented sweet potato vine 100 kg, concentrated material 20 kg, corn flour or broken rice 30 kg, rice bran or wheat bran 10 kg.
2. Fermented sweet potato vine 150 kg, pig premix (you can choose, for example, 500 g of "New Hundred Days' slaughter" or 500 g of "late pig concentrate supplement"), 30 kg of soybean or peanut bran, 60 kg of corn flour or broken rice, and 0/0kg of rice bran or wheat bran/kloc.
Fermenting sweet potato vines with film bags is simple and practical, can be sealed for more than half a year, is convenient to use, and can also be transported and sold.
Fermented sweet potato vines can be fed to local pigs and hybrid pigs.
