Laying chickens are more harmful to vitamins

In order to increase the egg production of hens, some chicken farmers randomly increase the amount of vitamins they supply. As a result, hypertrophy occurs in laying hens, which in turn 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.

The vitamin A content per kilogram of feed in vitamin A layers is 4,000 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.

The vitamin D content per kilogram of feed for vitamin D layers is 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.

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

The vitamin K content of the vitamin K layer per kg of feed is 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.

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