Prevention and treatment of vitamin A deficiency in meat ducks

In the process of raising meat ducks, meat ducks are often prone to metabolic diseases characterized by visual and motor impairment, which is called vitamin A deficiency in meat ducks.

Symptoms of vitamin A deficiency in meat ducks

The typical symptoms of diseased ducks are milky exudates from the eyes, the upper and lower eyelids are stuck by exudates, and the conjunctiva is opaque. When the disease is serious, large chunks of white cheese-like substances accumulate in the eyes of diseased ducks, and even corneal softening and perforation occur, resulting in blindness of diseased ducks.

Once diseased ducks with vitamin A deficiency are found, feed rich in vitamin A should be added to the diet as soon as possible, such as increasing the proportion of yellow corn in the formula feed, and the feeding of green feed can not be interrupted. It must be noted that vitamin An is a fat-soluble vitamin with poor thermal stability and is easy to be oxidized and invalidated in the process of feed processing, preparation and storage, so feed rancidity, fermentation and heat production should be prevented.
