Many leaves contain abundant plant proteins and various nutrients needed for pig growth and development and can be used as pig feed. There are many kinds of leaves that can make pig feed in nature. Commonly used are hedgehog leaves, poplar leaves, willow leaves, eucalyptus leaves, mulberry leaves, citron leaves, pine needles, apple leaves, pear leaves, mountain leaves, apricot leaves, peach leaves, Grape leaves, persimmon leaves, jujube leaves and so on. In addition, acacia flowers and poplar flowers are good feed for pigs. The leaves used as feed are scientifically processed to not only improve their palatability, but also have obvious effects on improving the utilization, digestibility and nutritional value of leaves. Now introduce several common simple processing modulation methods for leaf feed.
Blister method
After picking the tender leaves, wash them with water first, put them in the cylinder or cement pool, scald with 80 to 100% warm water, and then soak in fresh water for 2 to 4 hours. The amount of clear water generally exceeds the material level. However, when immersing apricot leaves, peach leaves, willow leaves, and mulberry leaves, fresh water should be changed several times to remove bitterness. Soak the soaked leaves and mix them into the diet to feed the pigs.
Drying method
The picked leaves are dried or dried, and after being crushed, they can be directly mixed into the feed and fed. Such as the Locust leaves, mulberry leaves, poplar leaves, and some fruit and leaves, etc., the amount of feeding is generally controlled at 5 to 10% of the total diet.
