The following is an introduction according to different seasons.

First, pay attention to the cleanliness of the environment in spring

In spring, due to the high rainfall and high humidity, it is extremely beneficial to the reproduction of bacteria, so we must do a good job in the cleanliness of the cage, so that the cage The house is clean and dry, and should be cleaned, cleaned, washed and disinfected frequently.

Including various tubers, melons, etc. Juicy feed is rich in water, with a water content of 75-90%, low in crude fiber and high in starch, low in protein content, only 1-2%, rich in potassium but deficient in calcium and phosphorus, and high in nitrogen-free extracts.

Three, roughage

The characteristic is low nutrition, high crude fiber content, and low protein and vitamin content. But maintaining a certain amount of crude fiber is conducive to the normal activities of the rabbit's digestive function.

IV. Concentrated feed

Including seed feed and processing by-products. Seed feed, mainly corn, barley, wheat, oats, rice and other gramineous plants, contains a large amount of nitrogen-free extracts, mainly starch.
