Maintain the stability of environmental conditions

The laying hens jumped from the start of production to the peak period and maintained high yields. This is a great physiological change and a hard process. At the peak period, the laying hens are in the period of the most metabolic and material conversion, and the period of relatively weak resistance, mental excitement and vulnerability to stress. If the feeding is not properly managed, the peak period will be frustrated, which will affect the egg production of the chickens throughout the year. The links that should be paid attention to in feeding management are as follows.

1. Optimal temperature

The optimum temperature for laying hens is 13-23 °C. The chicken body is high in temperature and there is no sweat gland. The high temperature is extremely unfavorable to the strict egg. When the temperature is above 30 °C, the egg production rate drops sharply; when the temperature is below 27 °C for a short time, the egg production rate does not change significantly, only the egg weight is reduced; when the temperature is below 16 °C, the feed utilization rate begins to decrease; the temperature is around 7 °C. It will produce low temperature stress and have a certain impact on laying eggs.

Therefore, it is necessary to prevent heatstroke in summer and keep warm in winter. The fundamental way to solve this problem is: the design of the house should be standardized, and there are environmental control equipment, ventilation, and reasonable lighting layout.

2. Comfortable living

Regardless of whether it is raised or caged, the living environment is especially important for hens. Chicken houses or chicken battery cages are places for eating, animal husbandry, sports, and places to sleep. Therefore, no matter what kind of feeding method, the chicken should be comfortable to improve the egg production potential. Studies have shown that cage density is closely related to mortality in laying hens. The layer chicken cages density only affects the egg production, feed and egg ratio.

3. It is strictly prohibited to cage

Laying hens are most sensitive during laying. In order to save money and raise the breeder, some chicken farmers will raise the chickens in the two chicken houses in the middle and later stages of laying eggs. As a result, the chickens were induced to fight, the number of dead and injured chickens increased, and the egg production decreased drastically. It must be remembered that caged and raised chickens cannot be caged or grouped after they are opened. This is an important principle of management.

4. Well ventilated

Air does not cost money and is available everywhere, but air quality is often overlooked. High material metabolism must be synergistic with high-quality gas metabolism in order to receive the best results. The peak period is also the period of the most oxygen consumption, so be sure to keep enough fresh air in the house. Therefore, we should pay more attention to the management of ventilation and ventilation, which is also important for disease prevention.

5. Light stability

The lighting program at the peak of egg production must be stable, and any slight changes will cause fluctuations in egg production. The principle of this period of light management is that the hours of illumination can only be extended according to the predetermined procedure and must not be shortened.
