How to raise a reserve hen in autumn?

Late summer and early autumn is the initial stage of the production of hens. The quality of management during this period is related to the efficiency of raising chickens. Therefore, in order to ensure the performance of laying hens, the following technical management points should be made.

Timely change and feed transition material. Generally, 20 weeks old chickens are fed before the eggs, which are also called transition materials. The material contains 1% calcium and 16.5% crude protein. When the chicken production rate reaches 2% to 6%, the calcium content of the feed should be 3.4% to 3.5%, and the crude protein content should reach 18%.

Strictly control the temperature of the house. The optimum egg production temperature for hens is 18°C. If the temperature is too high or too low, the nutrients needed to maintain the diet will increase. When the temperature is lower than 13 °C, it will affect its growth and egg production. At high temperatures, the intake of laying hens is reduced. If the proportion of protein in the diet is not increased in time, the development of the reproductive system will be delayed and the production will be postponed.

Adjust relative humidity and ventilation. The relative humidity of the chicken house is required to be 55% to 65%, and the relative humidity of the house at 1 to 3 days of age is 70%, which can be reduced to 50% after 4 weeks of age. Humidity cannot be too high, otherwise chicks will lose appetite and delay sexual maturity. If the ventilation is poor, harmful gases in the air will increase, the humidity will increase, and the oxygen content will decrease, which will cause the reserve hens to stunt and delay production.

Provide enough clean drinking water. The first-born hens are in great need of drinking water. Generally, each primal hen needs 100-200 grams of water per day. Therefore, first-laying hens should not be deprived of water every day. It is best to use flowing water tanks for water supply, and to provide 2 to 3 times of dilute brine every week to enhance their constitution and increase their intake. Daily carrots or green diets can also be fed to increase the protein content of their diet.
