Ducks generally lay eggs in the early morning. Therefore, ducks must maintain a high blood calcium concentration in the early morning, otherwise they will produce sand shell eggs, misshapen eggs, and even cause decreased egg production. When preparing egg-laying duck feeds, it is necessary to have a fast-absorbing calcium source and a slowly-absorbing calcium source. Stone powder and shell powder are usually used as calcium sources at the same time.
Mildew prevention
Feed ingredients and prepared feeds should be stored in ventilated, dark, and dry places to avoid oxidation of the fat in the feed and damage to vitamin A and vitamin E. Place a layer of moisture-proof material between the feed and the ground to prevent feed build-up and mildew. Moldy feed is prone to cause duck poisoning, pupa and so on. In addition, the feed store should pay attention to pest control and rodent damage. Vitamin supplements
Vitamin B1 ducks often eat fresh mollusks such as fish, shrimp and snails. These animals contain a substance called thiamine that can destroy vitamin B1, so ducks are prone to vitamin B1 deficiency. The disease occurs mostly in young ducklings and often occurs within 2 weeks of age. Therefore, in the case of ducks able to eat aquatic animals, it is necessary to increase the vitamin B1 content in the diet, especially in ducklings.
Vitamin D deficiency often occurs in ducks supplemented with vitamin D, which is caused by insufficient supply of vitamin D in the diet or insufficient exposure of the birds to sunlight. Diseased waterfowl showed poor growth and development, feathers were unorganized, dull, and production decreased. Shells and soft shells were produced, and eggshells were easily broken. Therefore, it is often necessary to additionally add cod liver oil or vitamin A, vitamin D3, vitamin E and the like to the duck feed.
Before use to wash the internal once, the water will be replaced with fresh water, so as not to accumulate scale. Washing should be careful not to scratch the surface coating. Check the power and the line is good, whether the smooth waterway. Whenever used, the water must be added to the water level line, and then power. In the course of use, should pay attention to adjust the water flow. Shut off the power immediately. Distilled water hose should not be too long, and do not insert the distilled water to ensure the smooth flow of distilled water. After use, you must first cut off the power, pause and then turn off the water.
