When the flock has a stress response (such as vaccination, transfer, etc.), 10% more vitamin A, vitamin E, vitamin D, and vitamin C should be added.
When chickens have chronic diseases (such as chronic respiratory diseases), 10% more vitamin A, vitamin E, and vitamin C should also be added.
Adding 5% more vitamin A1 to broiler feed can increase feed returns and help speed up the growth and development of chickens; for chicks, the lower the vitamin A content in feed, the higher the incidence of coccidiosis in chickens. Therefore, when chickens suffer from coccidiosis, 20% more vitamin A, vitamin K, and vitamin C should be added to the feed.
When chickens suffer from fatty liver syndrome, add 5% choline chloride and 10% multivitamin.
In the hot summer, 2% more vitamin C should be added to chicken feed to improve disease resistance, lower body temperature, increase production performance, and reduce stress response.
During the peak period of laying hens, 2% more vitamin B2 should be added; in order to increase the hardness of the eggshell, in addition to 2% more calcium should be added to the feed, 2% more vitamin A and vitamin C should be added .
When pullorum and coccidiosis occur in chickens, double the amount of multivitamins should be added to the feed.
When a certain type of vitamin deficiency occurs in chickens, the amount of vitamins added in the feed should be three times the constant.
The amount of vitamins added in feed for young chickens and breeders should be twice the normal amount.
Generally speaking, caged chickens need to add 10% more multivitamins to the feed of free-range chickens.
If the feed is used for too long (more than one month), 5%-10% more multivitamins should be added to make up for the loss of vitamins.
