Chickens are too cold and cold. During cold and cold seasons, physical and production performance declines, consumption of materials increases, egg production decreases, and colds and other respiratory infections are easily caused. Cold and chilly, if you add appropriate additives in the feed, you can enhance the body immunity.
Cod liver oil: It mainly contains vitamin A and vitamin D. It has the functions of strengthening the body, improving the quality of egg shells, and strengthening the ability to resist cold stress. Cod liver oil is best oil or water, so it can be used together with other drugs.
Vitamin E: Low temperatures can lead to decreased ovary performance and reduced egg production. Vitamin E is usually added in an amount of 10 milligrams per kilogram of diet. In the early spring, it needs to be increased by 2-6 times, which can increase immunity and egg production rate.
Vitamin C: It has the functions of anti-infection, detoxification and anti-stress, etc. It can increase chicken resistance to hypothermia and diseases, prevent infectious diseases and increase egg production rate. Adding 5 grams of vitamin C per 100 kilograms of chicken feed can reduce feed consumption and increase egg production.
Calcium: When the chicken body is deficient in calcium, under soft shell eggs, severe toe twitching, life-threatening, the demand for calcium in early spring chickens increased accordingly.
Paprika: rich in carotene and a variety of vitamins. Adding 1% chili powder to the chicken diet in early spring can improve chicken immunity and egg production.
Iodine: Iodine can enhance cold and warm effect. Can supply iodine-containing salt, the same amount as ordinary salt; or add kelp in the feed, the proportion of the amount of diet added 2% -6%, kelp cold, with appropriate amount of ginger to ease the cold.
Iron: Animals lack iron and have a reduced ability to resist cold and cold. Iron supplementation is very important for laying hens. The amount needed is 35-45 mg per kg of diet.
