It is not uncommon for chickens to lay double yolk eggs, which is also a type of abnormal egg, but the nutritional value of double yolk eggs is no different from that of ordinary normal eggs, and we can also eat them normally. Today, we don't talk about the nutritional problems of eggs, mainly to analyze the reasons for chickens to lay double yolk eggs and improvement methods, hoping to provide some reference for the majority of farmers.
The double yolk egg produced by the hen is mainly a process in which two egg cells mature at the same time, and then leave the follicle and enter the oviduct, after which they are wrapped in the oviduct by substances such as egg white and eggshell, thus forming a double yolk egg. While double yolk eggs may be heavier and larger than regular eggs, their nutritional value does not increase. Conversely, double yolk eggs are more likely to break and have a lower hatching success rate.
Chickens laying double yolk eggs can be caused by several reasons:
1.Chickens are frightened during egg laying.
Stress during egg laying can easily cause follicles to rupture, excreting two or more yolks, which enter the fallopian tubes and are encapsulated by egg whites to form double yolk eggs. In addition, chickens encounter sudden power outages or large changes in light time during egg laying, which will cause endocrine disorders, resulting in double yolk eggs.
2.Diseases of the reproductive system
Severe inflammation of the fallopian tubes in chickens causes oophoritis, which will increase the probability of chickens laying double yolk eggs.
3.Physiological factors
It is more common in young hens at the peak of egg production. Young hens are prone to produce double yolk eggs due to the vigorous endocrine and excessive secretion of follicle-stimulating hormone and ovulation-inducing hormone.
When we encounter the problem of double yolk eggs laid by hens, we can feed chickens: Weikuang Swordsman + Excellent Egg Swordsman, regulate endocrine, relieve stress, improve the growth performance of hens, and improve egg production quality. At the same time, try to keep the feeding environment stable, suitable for hens to lay eggs, and reduce the stress of the flock.
