How to preserve high-quality feed peanut vines for livestock and poultry
Peanut vines are high-quality feed for livestock and poultry and should be carefully collected for feeding livestock and poultry. Peanut vines are rich in nutrients. According to analysis and determination, the growth of peanut vines stems and leaves contains 12.9% of crude protein, 2% of crude fat, 46.8% of carbohydrates, including crude leaf protein content of up to 20%. The crude protein content in peanut vines was 1.6 times that of pea straw and 6 times that of straw. The energy produced by the consumption of 1 kilogram of peanut vines by livestock and poultry is equivalent to the energy produced by eating 0.6 kilograms of barley. In other words, 300 kg of peanuts are generally produced to obtain 300 kg of peanut vines, and the 3O0 kg of peanut vines produce the same energy as 180 kg of barley. Peanut vines are not only rich in nutrients, but also soft in texture and can be eaten by livestock and poultry. The use of peanut vines to feed livestock and poultry is an important way for rural areas to open up feed resources and to develop the grain-saving livestock husbandry industry. Farmers preparing peanuts and vines for livestock and poultry should harvest vines during the peanut harvest season. The vines should be promptly dried and piled after harvest. Rainy days should not be harvested, let alone wet vines. Otherwise, the vines will become yellowish or moldy. In the case of a plastic film covered with groundnuts, the mulch remaining on the vines should be removed when the vines are harvested. After drying the peanut vines, the impurities and the clay were removed and then pulverized into a powder. When used, peanut vine powder is directly mixed into the feed to feed livestock and poultry. According to experiments, the appropriate amount of peanut vine powder in livestock and poultry feed is: pigs account for 10% to 15%, poultry accounts for 5% to 8%, cattle and sheep account for 30% to 50%.
