Vitamin A is a substance required to maintain the integrity of all epithelial tissues in animals, and plays an important role in maintaining the growth and development of turtles and their normal physiological functions. It has effects on eye diseases, skin diseases, urinary system diseases, and respiratory system diseases of pet turtles. Daily maintenance and feeding Generally speaking, as long as pets are not fed food all the time, symptoms of malnutrition will rarely appear. In addition, the current feed generally guarantees a balanced nutrition, but I am afraid that the turtles will get tired of eating, so it is okay to occasionally feed some vegetables, millet and shrimp.

The importance of vitamin A to pet turtles

(1) Influence on vision. Vitamin A can promote the formation of photosensitive pigments in turtle visual cells, adjust the ability of the eyes to adapt to the strength of external light, and maintain normal visual response, so if pet turtles (especially tortoises) are not allowed to see and bite when feeding Symptoms can be improved with adequate vitamin A supplementation.

(2) The role of prevention and treatment of ophthalmia. Appropriate supplementation of vitamin A is helpful for the prevention of eye diseases. At the same time, when the turtle suffers from eye inflammation, in addition to symptomatic medication, appropriate vitamin A supplementation during the disease period is helpful for the recovery of ophthalmia.

(3) Role in the treatment of soft shell disease. Vitamin A can promote bone growth. For turtles suffering from soft shell disease (symptoms are soft carapace and plastron, sometimes the edge of the carapace is deformed and rolled up, sometimes the carapace is sunken, etc.), in addition to calcium and vitamin D supplementation. Appropriate supplementation of vitamin A in addition to help the recovery of sick turtles.

(4) A variety of skin diseases in pet turtles--skin rot, scabies/boils, and tortoise (the carapace of turtles is a derivative of the epidermis and dermis, so it is said that rot Nail disease can also be regarded as a skin disease). Vitamin A can regulate the growth of epithelial tissue cells, maintain the normal shape and function of epithelial tissue, ensure the integrity of the turtle's skin barrier function, make it less susceptible to bacterial damage, and prevent pet turtles from suffering from some skin diseases. At the same time, in diseased turtles that have already suffered from related skin diseases (skin rot, scabies/boils, nail rot, etc.), appropriate supplementation of vitamin A can promote the formation of new skin. Conversely, lack of vitamin A can lead to decreased skin elasticity, dryness, roughness, and loss of luster.

(5) Effects on respiratory diseases of pet turtles. Vitamin A plays an important role in maintaining the integrity of respiratory epithelial cells. When vitamin A is deficient, epithelial cells proliferate and become keratinized and desquamated, reducing the ability to defend against germs and weakening the barrier function of the respiratory tract, which can easily lead to respiratory diseases.

(6) Effects on the urinary system health of pet turtles. The maintenance effect of vitamin A on the integrity of epithelial cells is also reflected in the urinary tract. Deficiency of vitamin A can lead to desquamation of urothelial cells, damage to the health of the urinary system, associated inflammation and even urinary tract stones in turtles.
