Abstract

The invention discloses a laying hen feed for improving phospholipid content of yolk. The feed consists of corn, wheat, dried corn vinasse, shelled barley, bean pulp, corn protein powder, calcium hydrogen phosphate, stone grains, salt, premix, lysine, methionine, composite enzyme preparation and soybean oil gum. The feed is rich and balanced in nutrition, and is added with the soybean oil gum. The soybean oil gum is rich in phospholipid, the soybean phospholipid can be converted into yolk phospholipid by biological processing of laying hens, and the yolk phospholipid is stored in yolk. The feed is suitable for the laying period of the laying hens, and can effectively improve the phospholipid content of the yolk by 5 to 10 times and increase the color of the yolk, so that the egg is promoted from a common nutritional matter to health-care food, the increasing diet nutrition requirement is met, and economic benefits of the poultry industry are improved.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a feed for laying hens with increased egg yolk phospholipid content. Background technique [0002] With the progress of civilization, people pay more and more attention to their health and pay attention to balanced diet and nutrition. Among them, phospholipids play an important role in a balanced diet because of their outstanding functions—promoting human growth, enhancing physical strength, improving immunity, strengthening the heart, protecting the liver, improving autonomic function, and anti-aging. It has been confirmed by research that the most practical sources of phospholipids are egg yolk and soybeans, and egg yolk phospholipids are superior to soybean phospholipids in terms of structure and function. However, in the current egg production, laying hens are generally fed with ordinary compound feed, and the egg yolk phospholipid content of the eggs produced from this is also lo...
