The relationship between the laying rate and the benefit of raising chickens how to improve the laying rate of laying hens

The laying rate of laying hens directly affects the economic benefits of chicken farmers, so increasing egg production is one of the important links of laying hens. Strengthening feeding according to the physiological characteristics and nutritional requirements of laying hens is beneficial to improve the laying rate of laying hens. The main methods of feeding and management are as follows:

Laying hens

Raise in stages:

The laying period of laying hens is divided into different stages according to their age and laying level, and different management methods can be adopted to improve the laying rate of laying hens. The two-stage method or the three-stage method is generally used.

The limit of the two-stage method is 50 weeks old. before this, the laying hens were not fully developed, and it was during the peak laying period, and the protein content in the feed should be 1617%. After 50 weeks of age, the development of laying hens is completed, and the egg production is not high, but decreases, so the protein content should also be reduced, controlled at 14-15%.

According to the age of laying hens, the three-stage method was divided into three stages: 20-42 weeks, 43-62 weeks and after 63 weeks. In these three stages, the content of protein in feed was 18%, 16-17% and 15-16%.

When raising in stages, the feed change needs a transition period of one to two weeks, and do not mutate, which will cause stress in the flock and affect egg production. This step-by-step feeding method can make the egg laying peak of the flock appear in advance and increase quickly. The peak of egg production lasted for a long time, which not only reduced the feed cost, but also increased the egg production of chickens.

Restricted feeding

Restricted feeding during laying period can improve feed utilization rate, save feed, reduce feeding cost, control laying hen weight, reduce laying hen maintenance needs, and increase laying hen production needs. Many factors such as laying hen breed, environment, temperature, season and so on should be taken into account in the implementation of restricted feeding. It is generally believed that the energy limit in feed should be reduced by 8% by 10%.

Adjust feeding

Based on the feeding standard of laying hens, the relative stability of the diet of laying hens should be maintained. No matter what the situation, the feed formula should not be changed greatly, and the raw materials and nutrients should not be greatly changed. Fine-tuning should be carried out to make the laying hens have the process of adaptation, otherwise it will affect the feed intake of laying hens and lead to the decrease of egg production. Every adjustment should carefully observe the feed intake and egg production of laying hens, so as to find out the reasons in time and adjust them in time. As long as we understand the physiological characteristics and laying rules of laying hens, strengthen feeding and management, provide a good environment, and operate each link carefully, can we improve the laying rate of laying hens.
