Ducks, geese commonly used feed are cereals, bran and so on. Simple processing of these feeds is more conducive to the absorption of ducks and geese. 1. The real cereals include corn, wheat, barley, oats, sorghum, broken rice, rice, millet, and sub-powder. If you feed with sorghum, be sure to crush it, or blanch it with soft water until the sorghum sprouts and feed. The outer shell of rice is very hard and must be ground before it is powdered. Since the rice shell has high fiber content, it should be fed less. 2, bran type - there are wheat bran, corn bran, rehmannia. These three kinds of feeds contain very high crude fiber content, such as the use of wheat bran and corn bran to feed laying ducks and meat ducks, and the amount in feed should not exceed 15%. These three kinds of cockroaches are also a good feed for geese, and generally cannot exceed 20% in feed. 3, roots, tubers and melons? There are potatoes, sweet potatoes (sweet potatoes), beets, carrots, pumpkins, zucchini and so on. They are also good feed for ducks and geese. If you use mixed powders to feed ducks and geese inside a house and add trace elements and multivitamins to the feed, you will not need to add roots, tubers and green feed. 4, bad residue type? Distillers grains, beer grains, bean curd residue, beet residue, etc., can be used to feed ducks and geese. If these feeds can be mixed with other feeds, the effect will be better. 5, green feed?? Including a variety of vegetables, artificially cultivated pasture and wild non-toxic grass, wild herbs and aquatic plants. Green feed contains relatively complete nutritional content, vitamin content, easy to digest, ducks and geese are very fond of eating, and green feed sources are relatively wide, low cost, is a good feed for feeding ducks, geese. This kind of feed should pay attention to pesticide residues, it is best to feed after cleaning. Silage radish leaves, barnyardgrass, and green grass are also good feeds and can feed geese in large quantities. 6, plant protein feeds have soy beans, beans, peas, soybean cake (broom), peanut cake, rapeseed cake, sunflower seed cake, corn umbilical cake and so on. This kind of feed should pay attention to collocation and carry out a simple rough mixing processing to achieve a balanced feeding. 7. Animal protein feed: fish meal, meat and bone meal, blood meal, feather meal, silkworm cocoon powder, small fish, shrimp, snail, cockroach, aphid, insect, etc. This type of high-protein and high-nutrition feed should also be carefully matched with a simple rough-mixing process to achieve balanced feeding. 8, inorganic salt feed, there are shell powder, stone powder, eggshell powder, bone meal, salt and so on. This kind of feed should pay more attention to the mixed processing. Generally, it should be mixed with other feeds. 9, sand?? Although the sand is not a feed, but can help the breeding of ducks, geese in the digestion and absorption of feed, so the sand should be placed in the circle, so that ducks and geese casually eat.
