How to improve the laying rate of laying hens? Detailed culture methods are attached.

Chicken and its by-products have always played an important role in people's recipes, and farmers attach great importance to laying hens in response to this market demand. So how to improve the laying rate of laying hens?

1. Laying hen breeding management

Laying hen breeding is mainly divided into three stages:

1. The first laying period in which the laying rate is less than 85%.

At this stage, attention should be paid to feed, light, disease and prevention of fallopian tube inflammation in laying hens. From the egg laying rate of 5%, from the youth feed to egg production material, until the egg laying rate reaches 30% can be stopped. Replenishing light can be carried out at the same time as changing materials, Qingwen Baidu San can be used to mix materials in autumn and winter, and drinking water can be killed to prevent infectious diseases. When the laying rate reaches 50%, a drug to prevent salpingitis can be used.

2. the peak period when the egg rate is more than 85%.

This stage is the period with the highest benefit of raising laying hens, and it is necessary to reduce the mortality of laying hens. Should pay attention to the stable provision of feed, continuous feed, water, chicken house electricity is stable, do not change the light time, intensity in winter to prevent drinking water from freezing, to give it a stable and comfortable living environment. We should pay attention to timely ventilation and strictly guard against thieves.

3. Late laying stage (the egg rate is less than 85% until elimination)

At this stage, the egg laying rate decreased, the feed intake remained unchanged, and chickens were prone to fatty liver due to obesity. Should limit the amount of feed or change low-grade egg feed, but pay attention to calcium supplements, preferably shell powder. The light can be extended for 1 hour, that is, 17h/d, in order to obtain the maximum benefit.

II. Matters needing attention in laying hen breeding

1. Temperature control

The most suitable temperature environment for laying hens is 8 ℃-28 ℃. High or low temperature will affect the laying efficiency of laying hens. Therefore, farmers want to raise good laying hens, so as to keep the temperature of the henhouse within a comfortable environment all the year round, so as to avoid having an impact on the growth and development of chickens because of excessive temperature differences throughout the year, thus affecting the laying rate of chickens.

2. Disease prevention

Farmers should regularly test the chickens for antibodies to the virus, so as to avoid causing a large number of virus infections to the chickens because of the failure of the antibodies. We should always pay attention to the immune level of the flock, not to indiscriminately vaccinate, and not to increase or reduce the amount of vaccine used in the flock. Once the chicken flock is infected, it is necessary to control the disease of the flock in time, and try to choose more sensitive drugs to control the disease.

3. Ingredients

In different seasons, feeding should be improved according to the different nutritional needs of chickens. In spring and winter, some high-fat and high-energy nutrients should be added to chickens to ensure that chickens can effectively survive the low temperature season. Farmers are not allowed to allocate feed freely, such as adding more corn to the feed ratio. Because there is no proportion of a variety of raw materials, it may lead to a lack of protein, vitamins, minerals and other ingredients. It leads to the decrease of egg laying performance, soft eggshell, thin eggshell and so on, and even leads to no egg laying peak at all.

4. Lighting

Light plays a decisive role in promoting the sexual maturity of chickens, so farmers must give proper light to the chickens. During the laying period, the light was kept for 18 hours a day, and the most suitable light intensity was 5lx. Especially in winter or foggy season, the lights must be turned on in time to illuminate, so as not to let the darkness hinder the development of chicken eggs.

Only by taking correct feeding and management measures to provide a comfortable and harmonious growth environment for hens, can laying hens have more high and stable production.
