Pig fermented feed and preparation method thereof

Abstract

The invention discloses a pig fermented feed and a preparation method thereof. The pig fermented feed comprises the following components in parts by mass: 30-50 parts of broussonetia papyrifera leaves, 10-30 parts of cake dregs, 8-12 parts of corn, 3-7 parts of green bran, 3-7 parts of wheat middling, 10-20 parts of wheat bran and a EM bacteria solution leavening agent. The sum of water in the EMbacteria solution leavening agent and water in the broussonetia papyrifera leaves accounts for 25%-35% of the total weight of the raw materials, the total part of the broussonetia papyrifera leaves and the cake dregs is 60 parts by mass, and the mass concentration of the EM bacteria solution leavening agent is 1%-10%. Pigs fed by the pig fermented feed disclosed by the invention are fast in growth, strong in disease resistance, short in feeding period and high in growth speed, and also have the characteristics of high slaughter rate and high lean meat rate.

Description

technical field [0001] The invention relates to a pig fermented feed and a preparation method thereof. Background technique [0002] Sulfur mulberry is a member of the genus Structura moraceae, and its aliases are peach tree, mulberry tree, mulberry seed, mulberry tree, sandpaper tree, grain wood, grain pulp tree, false bayberry, etc. It is widely distributed in North China, Central China, South China, It is very common in Southwest and Northwest provinces, especially in the South. The mulberry leaves are rich in protein and vitamins. After air-drying, the crude protein is about 20%, the crude fat is about 12%, the crude fiber is about 9.5%, and the crude ash is about 12%. [0003] As a herbaceous plant, mulberry tree has relatively high crude fiber content. If animals eat it without any treatment, especially monogastric animals like pigs, it will cause a lot of burden on the digestive system and even cause death. If you want to use it To feed pigs with mulberry trees, fee...
