First, the preparation of duck meat feed. To ensure that the meat duck can both develop normally and fully develop its genetic potential, the feed should be formulated according to its different physiological stages and nutritional requirements.
1, feed ingredients. The selected feed ingredients should be of adequate source, reliable quality, and meet national feed hygiene standards.
2, scientific preparation. Pay attention to the feeding methods, living environment, food source structure and nutritional characteristics, and production performance characteristics of meat ducks. If meat ducks are reared by grazing, the growth rate of the meat ducks is slow, and feeds should be formulated based on the nutritional characteristics of the food obtained through grazing, so as to improve the feeding effect and reduce the feeding cost. The specific feed formula is: 1 duckling feed (%): corn 50, cabbage 20, broken rice 10, bran 10, fish meal 7.5, meat powder 1, shell powder 1, salt 0.5. 2 ducks and fattening feed (%): corn 50, wheat 17, bran 12, broken rice 10, cabbage cake 5, fish meal 4.5, shell powder 1, salt 0.5.
3, good palatability. The palatability of the feed is better, the nutrient content is stable, and it is easy to store. Whether artificially formulated feed or mechanical processing, the final feed product should be mixed.
4, prohibit the use of illicit drugs. Especially in the late growth period of meat ducks, it is prohibited to use any pharmaceutical feed additives to ensure the safety of duck meat products.
Second, the preparation of duck duck feed.
1, 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.
2, suitable for nutrition. 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%.
3, 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.
4, 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.
