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. There are 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 with 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%. 3, roots, tubers and melons are potatoes, sweet potatoes (potato), 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. There are distiller's grains, brewer's grains, bean curd slag, beet slag, etc., which 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, artificial cultivation of grass and wild non-toxic grass, wild vegetables and aquatic plants. 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. Vegetable protein feeds include soybeans, broad beans, peas, soybean cakes, peanut cakes, rapeseed cakes, sunflower seed cakes, and corn umbilical cakes. 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 meal, fish, shrimp, snail, cricket, aphids, insects and so on. 8, inorganic salt feed have 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, although the sand grain is not a feed, but can help the breeding of ducks, geese feed digestion and absorption, so the sand should be placed in the circle, so that ducks and geese casually eat.
