Several key periods of high-yielding laying hens.

The level of egg production in the process of laying hens is directly related to the breeding efficiency. To increase the output of laying hens and cultivate high-capacity laying hens, it is necessary to do a good job in feeding and management during these critical periods.

35 days for life

At 35 days, whether the average body weight and uniformity of the egg chick group can reach the standard is positively correlated with the age of sexual maturity, egg laying hens persistence, and the number of final eggs produced. If more than 80% of the chicken flock can reach the standard body weight, Then the genetic potential of the breeder such as egg-laying performance can be fully exerted; it means that the immune system is well developed, and it can produce a good immune response after immunization.

80 days high yield

At the age of 80 days, the ovaries and fallopian tubes of the laying hens begin to develop. At this time, they are most likely to be infected with bacteria such as Dasha and Salmonella, resulting in poor development of the fallopian tubes and ovaries of the laying hens and intractable inflammation of the fallopian tubes in the later stage, resulting in a later peak. Period is not high, eggshell quality is not good, fallopian tube inflammation should not be eliminated and many other phenomena.

When the egg production rate is 5%

At this time, the chickens have just started production, and they are most prone to endocrine disorders and spleen and stomach disorders, which are manifested as loose and unformed feces, slow feeding, and low resistance. And this is the period of high-speed follicle development and fallopian tube formation, so it is necessary to regulate the spleen, stomach and endocrine, supplement nutrition and increase the body's resistance at this time.

When the egg production rate is 50%

At this time, most of the chickens have already started production, and the fallopian tubes are relatively stressed, which is prone to inflammation of the fallopian tubes and pecking of the anus. The follicles develop rapidly, require more nutrients, and the liver and kidneys have a large load. At this time, the body's resistance is low. Therefore, the chickens should focus on anti-inflammatory, regulating fallopian tubes, increasing resistance, and supplementing balanced nutrition.

When the egg production rate is 90%

At this time, the egg production rate officially peaked, but there are still 10% of laying hens that do not lay eggs. To achieve greater egg production performance, three points need to be done:

1) Promote fallopian tube development and follicle development.

2) 100% elimination of fallopian tube inflammation.

3) Supplementary nutrition increases the body's resistance.

When the egg production rate drops to 85%

When the egg production rate of chickens drops to 85% under normal circumstances, the storage in the body begins to be insufficient. This is also the period when the body's tissues and organs begin to age and the digestion and absorption functions decline. Therefore, if the feeding management is not strengthened at this time, it is most likely that the egg production rate will drop quite rapidly.

The root cause of the decline in the performance of laying hens

Varieties, intensive and large-scale feeding methods, mycotoxins, drug side effects, aging, weather changes, immunizations, beak cutting, diseases, unreasonable feeding and management and other stress factors can all cause the body's immunity to decline and make the body's qi and blood double. Loss, in a sub-health state.
