Chickens Cage Prevention and treatment of vitamin A deficiency in laying hen
Farmers should usually pay attention to the vitamin supplementation of chickens. Here are some key points for the prevention and treatment of vitamin A deficiency.
Vitamin A is a substance necessary for poultry growth, vision, and mucosal integrity, especially to protect the health of the epithelial cells of the respiratory tract, upper digestive tract, and urinary tract mucosa. Vitamin A can be synthesized from carotene in the body.
Necropsy: There are small white pustules in the nasal cavity, mouth, esophagus and pharynx, which can extend to the sac. Subsequently, small ulcers formed on the mucosa, with inflammation products surrounding them.
Prevention: Pay attention to the coordination of feed. The diet should be supplemented with a diet rich in vitamin A and carotene. For adult hens with disease, each chicken is fed a quarter spoon of cod liver oil 3 times a day. Abdominal lesions were washed with a 3% boric acid solution once a day with good results.
The above are the key points for the prevention and treatment of the lack of vitamin A in laying hens in the process of laying hens in cages.
