The harm of early laying of laying hens

Laying hens are the only source of eggs because there is a great market demand for eggs in our country. So now the breeding area of laying hens in our country is still very large, when raising laying hens, it is very important for laying hens to start production. Many people think that the sooner the laying hens start production, the better. In fact, this is wrong and the harm is very great. So what is the harm of laying hens early? What is the reason for laying hens to start laying early? Let's take a look at it with the editor.

1. Reasons for the early start of production

When raising laying hens, in order to improve the yield and breeding efficiency, many chicken farmers promote the laying of laying hens in advance by means of adding light in advance and changing laying materials. During the breeding period, the laying hens have certain requirements on the intensity and time of light. If the light time is too long and the intensity is too strong, it is easy to lead to the laying time of laying hens earlier. Therefore, if the breeding period is not regulated in time during the long period of natural sunshine such as the Winter Solstice and the Summer Solstice, then it will also be one of the main reasons for the laying of laying hens too early.

2. The harm of starting production early

If the laying hens start early, it will cause great harm to the laying performance and the body of the laying hens. If the laying hens start too early, the eggs laid will be very small, the single egg will be lighter, the laying rate will decrease, and the peak duration of egg production will be very short. After the peak, the laying rate of laying hens will plummet. As for the chicken body, the chicken bone and chicken meat are not fully mature, which affects the normal weight gain of the laying hens. Reduce the resistance of laying hens, easy to appear premature aging phenomenon. And it is also easy to have dystocia, prolapse of anus, pecking anus and other bad phenomena, resulting in an increase in death rate.

3. Control measures

For the phenomenon of laying hens starting prematurely, we should make different control measures according to the actual situation. If the production has started too early, then we should reduce the light intensity and shorten the light time in time. The sunshine time should not exceed 16 hours per day. And before laying hens, feed in time, if there is a phenomenon of prolapse of the anus, then local treatment should be carried out with internal medication. For the anus-pecked chicken, the general situation will be more serious, basically lost the value of treatment, so we should pay attention to its timely elimination.

As for the laying hens that have not yet begun to give birth too early, we should give priority to prevention to avoid the phenomenon of starting production too early. First of all, chicken farmers should strengthen their own awareness, do not rush for quick success and quick profit for the sake of production, and advance the opening time of laying hens by various means, on the contrary, the loss will outweigh the gain. When the laying hens grow to the age of 10-20 weeks, the daily light time should be kept at about 12 hours, not too long, and the light intensity should not be too strong. As for the breeding chickens during the period of the Winter Solstice and the Summer Solstice, they should be regulated and regulated according to their specific growth conditions.

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