The spring climate changes from cold to warm, the temperature gradually rises, and sunshine is gradually extended, which is a good season for chickens to lay eggs. The following are the main points for laying hens in spring:
1 pay attention to the temperature, to avoid the flock to catch cold
In the early spring, when it is warm and cold, the temperature difference between day and night is large (especially in the north). While gradually removing the cold protection facilities, pay attention to avoiding the coldness of the chickens. Don’t loosen the management due to saving time, causing the temperature difference between day and night to be too large, causing the chicks to suffer from cold.
2 pay attention to ventilation, maintain normal humidity
According to the temperature, wind, wind direction and decide the number of windows to open, size, and direction, we must first open the upper window, open the lower part; open the window during the day, close at night; open the window when the temperature is high, and close the window when the temperature is low Open the window when there is no wind and close the window when it is windy. This will prevent respiratory diseases in the spring and increase egg production. Ventilation should also pay attention to insulation.
3 pay attention to reasonable lighting
Laying hens must have 14 to 17 hours of light daily. Such as using red light shine better.
4 Pay attention to epidemic prevention
After entering the spring, the house should be cleaned and disinfected once to reduce the threat of disease.
Diseased chickens, weak chickens, disabled chickens, non-laying hens, and laying hens with poor egg production were culled from the flock.
Strengthen disease prevention work. Conditional chicken farms should perform antibody monitoring for Newcastle disease, infectious bronchitis, and other diseases. If abnormalities are detected, immunizations can be carried out immediately and preventive drugs can also be administered.
5 attention to feed nutrition comprehensive
Reduce energy feeds and reduce the metabolic energy in chicken feed by reducing the amount of energy feeds such as corn.
To increase protein content, the amount of crude protein in feed should be increased according to the increase in egg production rate. Generally, the egg production rate is increased by 10%, and the digestible protein in feed increases by 0.5%, but the maximum is 18.5%. The method is to add more protein. Fishmeal, bean cake.
To increase the mineral content, the calcium in the feed should be adjusted to 4%, and the phosphorus should be adjusted to 0.6%. If indigestion is found, the loss of appetite and other phenomena should be appropriately increased to 0.5%, and the corresponding increase in ore The amount of material additives.
To supplement vitamin feed, the method is to increase the proportion of various vegetables in the feed. It is also possible to increase the green and juicy feed from 15% to 32% and increase the amount of multivitamins in the feed.
