2021-03-08
Chickens love temperature and are afraid of cold. In the cold and low temperature seasons, physical fitness and production performance decrease, material consumption increases, egg production decreases, and respiratory infections such as colds are easily contracted. If appropriate additives are added to the feed, the cold resistance of the chicken body can be enhanced.
Cod liver oil: It mainly contains vitamin A and vitamin D, which can enhance physical fitness, improve eggshell quality, and enhance the ability to resist cold stress. Cod liver oil is best to use oil or liquid, so that it can be used at the same time with other drugs.
Vitamin E: The low temperature in winter will cause the performance of chicken ovaries to decrease and egg production will decrease. The usual dosage of vitamin E: 10 mg per kilogram of diet, 2-6 times in winter needs to increase the dosage to improve cold resistance and egg production rate.
Vitamin C: It has the effects of anti-infection, detoxification and anti-stress, can increase the chicken's resistance to cold and diseases, prevent infectious diseases, and increase egg production. Adding 5 grams of vitamin C per 100 kilograms of chicken feed can reduce feed consumption and increase egg production.
Calcium: The chicken body is lack of calcium. In mild cases, soft-shelled eggs are laid. In severe cases, the toes may twitch, which is life-threatening. In winter, low temperature and less light will increase the demand for calcium in chickens.
Chili powder: rich in carotene and multiple vitamins. Adding 1% chili powder to the chicken diet in winter can improve the chicken's cold resistance and egg production rate.
Iodine: Iodine supplementation can enhance the effect of cold resistance and warmth. There are two methods: supply iodized table salt with the same amount as ordinary table salt; or add kelp in the feed, the amount of which accounts for 2%-6% of the diet. The kelp is cold, and an appropriate amount of ginger can be used to alleviate its coldness.
Iron: Animals are deficient in iron, their ability to resist cold is reduced, and they are afraid of cold. Iron supplementation for laying hens is very important, and the required amount is 35-45 mg/kg diet.
