Harm of laying hens starting too early and too late

Laying hen breeding is very common in China, and the main purpose of layer breeding is naturally eggs. The starting time of laying hens will directly affect the production of laying hens. If the production time is inappropriate, whether it is too early or too late will have a great impact and reduce the efficiency of breeding. So what harm will be caused by laying hens too early and too late? Today, the editor will give you a brief introduction. Let's take a look at it.

1. The harm of starting production too early

There are many dangers for laying hens to start laying too early. First of all, it will cause great harm to the laying hens themselves, which will hinder the development of the bones and meat of the laying hens, resulting in too small body, underweight and too thin body to accelerate the speed of aging. The phenomenon of dystocia and prolapse of anus and pecking of anus are easy to occur. Moreover, the eggs laid by early laying hens are still very small, the weight of eggs is also very light, the laying rate is low, and the peak period of egg production is also short. It will have a great impact on both the yield and the growth of laying hens, resulting in a sharp decline in breeding efficiency.

2. The harm of starting production too late

Starting too late will also cause great harm to the body and laying performance of laying hens. First of all, because the eggs will be larger if they are laid late, so laying hens are prone to laborious dystocia, which is the same as early delivery, and it is also easy to prolapse the anus. And if the production is too late, it is easy to produce oversized eggs at the beginning. As a result, the laying peak of laying hens will be delayed, and the number of laying days will be reduced, so the total egg production will also decrease. At the same time, it will also inhibit the overall growth and development of laying hens, seriously endangering the economic benefits of chicken farmers.

3. How to prevent and cure

In order to prevent laying hens from starting too early, we should do a good job of artificial lighting for chicks whose shells are broken from September to April of the following year. In the breeding period, we should also pay attention to the law of natural light to gradually reduce the amount of artificial light, so as to avoid the phenomenon of precocious puberty caused by prolonged light time. For laying hens that are too late, the light time should be controlled at about 16 hours a day, and the laying feed should be fed properly. The main thing is to give priority to prevention, at the end of laying hens, we should reasonably increase the light, and then properly feed the egg fodder at the age of about 20 weeks.

4. Appropriate time to start production

When we know the right time for laying hens. First of all, the laying rate should be taken as the first criterion, usually if the laying rate of the whole population reaches about 5%. Then it can be used as the date of birth. And if we want to take the age of the first day of production as the evaluation standard of the opening time of production, then it should be determined according to the breed of chicken, if the breed is different, then the age of starting birth is also different, so we should pay more attention to it.

The above is a brief introduction to the harm of laying hens too early and too late. That's all for today's introduction. This article is for reference only. I hope it can help you all.
