Feed formula employing duckweed powder and water flea to replace fish meal for laying hen in brooding period

The invention discloses a feed formula employing duckweed powder and water flea to replace fish meal for laying hen in brooding period. The feed formula is prepared from the following components in percentage by weight: 56% of maize, 5% of duckweed powder, 34% of water flea, 3% of bran, 1.7% of calcium hydrophosphate, and 0.3% of table salt. According to the formula, duckweed powder can meet the demand of laying hen on protein; the water flea is rich in source and never used up, and is easy to digest; the traditional breeding formula is highly insufficient in water flea and the feed is difficult to digest; therefore, the duckweed powder and the water flea adopted in the formula to replace the fish meal in the traditional breeding formula can be used for improving the egg quality, increasing the economic benefit and increasing the survival rate, and can be easily digested by the laying hen and fully absorbed, so that the demand of the laying hen growing in the brooding period can be met; the formula is suitable of laying hens at the age of 0 to 10 weeks.
