The solution to the decline of chicken egg production

The laying of chickens has a certain rule, that is, it reaches the peak of egg production a few weeks after laying, and after a period of time, it begins to decline slowly until the end of egg production. If there is a sudden decline in the laying rate of laying hens, it is necessary to conduct a comprehensive inspection in time, find out the cause, and take corresponding measures to prevent it:

First, reducing the change of stress season and the occurrence of disastrous weather will lead to sharp changes in temperature and humidity. If the heat preservation effect of the henhouse is not ideal, it will have a greater stress effect on the laying hens, resulting in a sudden decline in the egg production of the hens. Therefore, when the seasons change and the weather is abnormal, the temperature of the chicken house should be adjusted in time and the ventilation condition should be improved. Adding a certain amount of vitamins to the feed can slow down the stress of chickens.

Second, the sudden power outage in the scientific light chicken house, or the light time and intensity out of control, are not conducive to the normal laying of chickens. During the laying period, we should strictly follow the scientific lighting system to avoid irregular lighting. During the laying period, the light time is 14 hours to 16 hours per day.

Third, to ensure that drinking water should always check the drinking water system, and timely maintenance should be carried out when water leakage or blockage is found.

Fourth, the scientific use of materials should choose safe, reliable, stable quality of full-price feed, the diet requires a sufficient amount of protein, methionine and appropriate vitamins and minerals such as phosphorus and sodium. At the same time, avoid sudden change of feed. If it must be replaced, the method of gradual replacement should be adopted, that is, first replace 1max 3, then replace 1max 2, and then change 2max 3 until all of them have been replaced. The whole process should be 4-5 days. Fixed feeding times, feed on time, do not suddenly reduce the amount of feeding or limit feeding, at the same time, the amount of feeding should be adjusted according to seasonal changes.

Fifth, keep clean and clean up in a timely manner to ensure the good sanitary condition of the chicken house. Routine disinfection should be carried out once or twice a week, and once or twice a day if there is an epidemic. 0.1% Weidao brand disinfectant or other safe disinfectant can be used to spray disinfect the ceiling, walls, floors and appliances of the chicken house.

Pay attention to daily observation and observe the feeding, feces, feathers, crowns, breathing and other conditions of the flock. If problems are found, they should be treated in time.

Usually, the suitable temperature in the chicken house is 18.3 ℃-23.9 ℃, and the relative humidity is controlled at 55% Mel 65%. At the same time, the air in the chicken coop should be kept fresh. Under the condition of no detector, it is appropriate for people to enter the chicken coop without dazzling, tearful and smelly smell.

Seventh, do not vaccinate during the laying period, vaccination should be carried out in the brooding and breeding period of the chicken, and do not feed a large number of preventive drugs during the laying period.

Reduce abnormal sound stimulation as much as possible to prevent cats, dogs, rats and birds from entering the henhouse.
