In addition to guaranteeing that they are full, they must also feed three substances.
Ferrous sulphate
During a large number of laying hens, laying hens have a strong blood circulation, and various substances (especially iron) are consumed in the body. Ducks often develop iron deficiency anaemia after they are born. If 100 mg of ferrous sulfate powder is added per kilogram of feed at this time, the occurrence of iron deficiency anemia in laying ducks can be prevented.
Bone meal fried with vinegar
After bone meal is fried with vinegar, calcium can become calcium acetate which is easily absorbed by ducks. Adding 3% of bone powder fried in vinegar to the duck and duck diet in the off season can quickly cure osteoporosis and osteochondrosis caused by calcium deficiency in the female duck.
pumpkin
Pumpkin has good palatability and is rich in nutrients. It can promote moulting of laying ducks and shorten the period of moulting. Each duck fed 45 grams a day can be chopped feed, pumpkin can also be cut open on the ground for ducks to feed.
