1, nutritious. Preparation of duck and duck diets should be based on the age of the duck and feed intake to determine the appropriate nutrient concentration of compound feed. Its reference formula is: 1 duckling (1 to 8 weeks): 58.7% of corn, 26% of soybean meal, 7% of vegetable aphid or cottonseed meal, 4% of stone powder (bone powder and shell powder), special premixed premixed 6 4%, salt 0.3%. The first week of ducklings is recommended to feed all of the full-grain pellets. 2 ducks in eggs (8 weeks to production): 64% corn, 16% soybean meal, 6% vegetable aphid or cottonseed meal, 9.7% stone powder (bone meal, shell powder), 4% pre-premixed 6%, Salt 0.3%, Kinsey peacekeeping amount. 3 Ducks with egg production period: 51% of corn, 22% of soybean meal, 3% of rapeseed or cottonseed meal, 10% of secondary powder, 9.7% of powdered stone (bone powder and shell powder), pre-premixed 6% of pre-mixed salt, salt 0.3%.
2, feed ingredients. Formulations should be easy to handle when selecting raw materials. It is required that the quality of feed ingredients is stable, the quantity is sufficient, the price is appropriate, and it has local resource advantages.
3, feed should be kept fresh. In order to prevent the feed from becoming mouldy, the feed should be stored in a dry place and the feed should not be stored in the duck house.
4, with additives. The main components of the additive are amino acids, vitamins and minerals. The data confirmed that 80 grams of methionine and 50 grams of lysine were added to the 50 kilograms of regular duck and duck diet. The fishmeal was reduced from about 4 kilograms to about 2 kilograms, and the egg production and egg weight were not affected. Vitamin supplements can completely replace the nutritional function of green feed, not only can play the role of vitamin supplements, but also save a lot of green fodder, reduce the labor intensity of duck farmers, reduce the cost of duck production.
