Addition of layer chicken vitamins

If the effect of overdose of vitamins on laying hens is very serious, some chicken farmers often increase the amount of vitamins in order to increase the egg production in order to increase the egg production. Hypervitaminosis occurs, but it affects the growth and production of laying hens. Addition of vitamins to layer chicken diets must be strictly adhered to standards, and arbitrarily increasing dosages can cause harm to laying hens.

First, the appropriate content of vitamin A per kilogram of feed for vitamin A layers is 4000 international units. When the feeding amount exceeds the feeding standard, it can cause hen vitamin A excess syndrome, manifested as mental depression or convulsions, feed intake decreased, serious eating, feathers fall off.

Second, vitamin D hens per kilogram of feed vitamin D suitable content of 500 international units. When the feeding amount exceeds the feeding standard, a large amount of calcium can be transferred out of the bone tissue of the laying chicken and promote the absorption of calcium in the gastrointestinal tract, so that the blood calcium concentration is increased, and calcium is deposited on the arterial wall, joints, renal tubules, and heart And other soft tissues, the clinical manifestations of loss of appetite, diarrhea, kidney stones, laying hens often die of uremia.

Third, vitamin E hens per kilogram of feed vitamin E suitable content of 5 international units. Overfeeding can lead to impaired fat metabolism in laying hens, leading to fatal or poisoned deaths.

Fourth, vitamin K layer per kilogram of feed vitamin K in the appropriate content of 0.5 mg. When fed excessively, because it stimulates inflammation of the gastrointestinal mucosa, the chicken shows a sharp decrease in appetite and diarrhea, resulting in a decrease in egg production and severely discontinue production.

Hyperlipidemia in laying hens is mainly due to prevention, and chicken rations are reasonably formulated according to feeding standards. For chickens that have already developed disease, they should immediately stop feeding vitamins and provide sufficient drinking water. Generally, they can gradually recover within 2 weeks.
