How to use leaves for pig feed?
Many leaves are rich in plant protein and a variety of nutrients needed for pig growth and development, which can be used as pig feed. There are many leaves that can be used as pig feed in nature. Among them, acacia leaves, poplar leaves, willow leaves, elm leaves, mulberry leaves, toon leaves, pine needles, apple leaves, pear leaves, mountain leaves, apricot leaves, peach leaves, Grape leaves, persimmon leaves, jujube leaves, etc. In addition, locust flowers and poplar flowers are good feed for pigs. The scientific processing and modulation of the leaves used as feed can not only improve its palatability, but also have obvious effects on improving the utilization, digestibility and nutritional value of the leaves. Now introduce several common simple processing methods of leaf feed.
1. Blister method
After picking the tender leaves, wash them with water, put them in a tank or cement pool, scald them with 80%~100% warm water, and then soak them in clean water for 2 to 4 hours. The amount of water is generally more than that The surface is enough. When soaking apricot leaves, peach leaves, willow leaves and mulberry leaves, you need to change the water several times to remove the bitterness. The soaked leaves can be chopped and mixed into the diet to feed pigs.
2, drying method
The picked leaves are dried or dried, and after crushing, they can be directly mixed into feed and fed. For example, locust leaves, mulberry leaves, poplar leaves and some fruit leaves, etc., the feeding amount is generally controlled at 5% to 10% of the total diet.
3. Salting method
Wash and chop the leaves, pour them into a tank or a cement pool, take 5% of the amount of table salt, press one layer of leaves and one layer of salt into layers for salting. After being salted, the leaves are not easy to rot, have a fresh fragrance and good palatability.
4, silage method
Wash the leaves, chop them, and drain the water, and then put them in the silage container layer by layer. If the leaves have too much water content, add 10% of the leaves to the chaff for mixed silage. When the water content is low , Can be adjusted manually by spraying water.
5. Fermentation method
First, the picked leaves or collected autumn leaves are dried and crushed into leaf powder. Use appropriate amount of water to make 2 kilograms of old dough for pasta into a thin paste, then add 5 kilograms of cornmeal and 10 kilograms of rice bran, mix well, stir into a thick paste, and let it ferment for 24 hours. Then add 50 kilograms of leaf powder and 10 kilograms of the worst, and stir thoroughly. The humidity should be held in the hand and see water drops on the hands. Then put it into the fermentation tank or pool, and then it will be steadfast and full. Afterwards, cover the tank (pool) mouth with a cover to keep the temperature at 30℃~50℃. It can be used after 48 hours of fermentation.
