In the process of rearing meat ducks, meat ducks are often susceptible to metabolic diseases with visual and behavioral disabilities as the main symptoms. This is known as vitamin A deficiency in meat ducks. The typical symptom of a sick duck is a cow's milk-like exudate from the eyes. The upper and lower eyelids are covered with exudates, and the conjunctiva is cloudy and opaque. When the disease is severe, large white cheese-like substances accumulate in the eyes of the diseased duck. The cornea even softens and perforates, eventually causing the diseased duck to become blind. Under normal circumstances, sick ducks have stagnated growth, apathy, thin body, unsteady walking, loose feathers, yellow skin in cheeks and calves, and weakness in exercise. If they are not treated promptly, they must die. Usually pay attention to feed diversification, green feed or poultry multi-dimensional factors are essential. According to the season and feeding conditions, carrots or carrots were the best in winter and spring, followed by leguminous green leaves (such as alfalfa, clover, milk vetch, broad bean seedlings, etc.). In the summer and autumn seasons, wild grasses such as barnyardgrass are the best, followed by green vegetables and pumpkins. Once a diseased duck suffering from vitamin A deficiency is found, a feed enriched in vitamin A should be added to the diet as soon as possible. For example, in the compound feed, the ratio of yellow corn is increased, and the green feed can not be interrupted. It must be noted that vitamin A is a fat-soluble vitamin with poor thermal stability. It is susceptible to oxidation and failure during feed processing, preparation, and storage. Feed rancidity, fermentation, and heat production should be prevented. Exogenous vitamin A can be rapidly absorbed in the body. After artificially supplementing exogenous vitamin A, symptoms of the diseased duck will soon disappear. Intramuscular injection of cod liver oil can be used for group therapy of vitamin A deficiency in ducks. Infants weighing 250 g or more can be injected intramuscularly with 1 ml each time, and can also be treated by adding 20 ml of cod liver oil per kilogram of concentrate.
