When raising chickens, in addition to the protein, carbohydrate and mineral needs of the laying hens, you must also pay attention to the addition of vitamin D, especially to provide vitamin D3, because vitamin D3 plays a key role in the formation of eggs. In the egg-laying season, vitamin D3 can fully exert the production performance of the chicken, and increase the feed compensation to a greater extent, so that the chicken produces more eggs and produces large eggs; in the off-season of laying eggs (winter), vitamin D3 can increase the egg production and change. The off-season of laying eggs is the peak season for laying eggs, increasing income and improving the economic benefits of raising chickens.

Supply method: First, you can feed more small fish, miso shrimp and other small animals in the water, fish meal, blood meal, silkworm cocoons, insects, etc., because these animal feeds are rich in vitamin D3. Second, you can feed more tender green grass, eucalyptus leaves, eucalyptus leaves, green leaves, carrots and other green and juicy feed. The third is to pay attention to let the chickens get more sun (especially in the winter), take a sun bath, and also artificial ultraviolet radiation to promote the synthesis and absorption of vitamin D3. Fourth, for laying hens that do not see sunlight in the indoor enclosure, it is necessary to add an appropriate amount of "animal multivitamins" and vitamin D3 preparations to the feed.
