Feeding hens vitamins avoid excessive
When the egg market is good, some chicken farmers often increase the amount of vitamins they feed in order to increase their egg production. This will lead to more eggs, which will lead to hypervitaminosis in laying hens and affect the growth and production of laying hens. egg. Addition of vitamins to layer chicken diets must be strictly adhered to standards, and arbitrarily increasing dosages can cause harm to laying hens. The optimum 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. The vitamin D content per kilogram diet for vitamin D layers is 500 IU. 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 appropriate vitamin E content per kilogram of feed for vitamin E hens is 5 IU. 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 kilogram 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. 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 the disease, they should immediately stop feeding vitamins and provide sufficient drinking water. Generally, they can gradually recover within 2 weeks.
