Self-matched duck feed attention

1. Ducks often eat mollusks such as fresh 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. 2. Vitamin D deficiency often occurs in laying ducks, which is caused by insufficient supply of vitamin D in the diet or insufficient exposure to sunlight. The affected ducks showed poor growth and development, feathery and dull feathers, decreased egg production, thin shells, soft shelled eggs, and easily broken shells. Therefore, it is often necessary to additionally add cod liver oil or vitamin A, D3, E, etc. to the duck feed. 3. Ducks usually 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.

Magnetic Stirrer applies to mixing or heating simultaneously, magnetic stirrer is suitable for the liquid or solid-liquid mixture viscosity is not very big. Using magnetic material of the same characteristics, by changing the ends of the base of polarity to drive a magnetic stirring rotation,  through the magnetic stirring rotation drive the samples, sample evenly mixed.
