The poultry layer cage system started poultry farming and it was recognized by farmers that poultry also have a need for vitamins. It can help chickens grow healthier and is a necessary substance for the integrity of eyesight and mucous membranes.

Farmers may not notice these problems. Today, I will explain to you the main points of prevention and treatment of vitamin A deficiency. I want to be helpful to poultry farmers.

Vitamin A can especially protect the health of the mucosal epithelial cells of the respiratory tract, upper digestive tract and urinary tract. Vitamin A can be synthesized from carotene in the body.

The manifestation of vitamin deficiency: small white pustules in the nasal cavity, oral cavity, esophagus and pharynx, which can extend to the sac. Subsequently, small ulcers formed on the mucosa, surrounded by inflammatory products.

What farmers need to do: Pay attention to the coordination of feed. The diet should be supplemented with a diet rich in vitamin A and carotene. For adult hens suffering from disease, each chicken is fed a quarter spoon of cod liver oil 3 times a day. Abdominal lesions are cleaned with 3% boric acid solution once a day, and the effect is good. 

Poultry farming is a meticulous work that requires careful observation of poultry by farmers. The above are the key points shared by poultry equipment manufacturers for farmers to prevent and control layer hens lacking vitamin A during the process of raising hens in  poultry layer cages.
