Measures for feeding and management of reserve hens

Spring breeding reserve hens enter the first birth stage in summer, and the flock management in this period is related to the economic benefits of chicken farms (households). Therefore, the following management measures should be taken for backup hens:

1. Timely change of ferry materials

Generally, 20-week-old chickens are fed with pre-egg feed, also known as transition feed, with 1% calcium and 16.5% crude protein. When refueling, the application of half a month to gradually complete the refueling process, do not be too hasty, in order to prevent diarrhea. When the laying rate reaches 2%-3.5%, the feed should contain 3.4%-3.5% calcium and 18% crude protein.

Second, control the condition of the first birth.

While replenishing calcium, the uniformity of population development should be grasped, and the large, medium and small reserve hens should be raised in groups and adjusted regularly. Do not sharply increase or reduce the material, its benefits can only be shown after 3 weeks, should not be acted in haste. The feeding amount of light-weight chickens should not exceed that of medium-sized chickens, so as not to affect sexual maturity due to fat deposition.

Third, strictly control the temperature of the enclosure

The optimum laying temperature for laying hens is 18 ℃ ~ 23 ℃. When the external temperature is lower than 18 ℃, the nutrition needed for maintenance will increase; when the temperature is lower than 13 ℃, it will affect the growth, development and egg production of laying hens, so when the temperature of the henhouse is too low and the feed is not increased in time, the production of hens will be delayed due to lack of energy. When the temperature is high in summer and autumn, the feed intake of laying hens decreases. If the proportion of protein in the diet is not increased in time, the development of the reproductive system of hens will be affected and the production will be delayed.

IV. Control and adjustment of lighting

Backup hens generally enter the stage of sexual maturity at the age of 15 weeks, and the natural light in this period is gradually shortened. If the illumination time is short, the time to reach sexual maturity is long, so we should start to supplement light after 15 weeks of age to meet the needs of sexual maturity of chickens. Generally speaking, the light time after 15 weeks of age should be maintained at the light hours of 15 weeks old, but the light should not be too strong to prevent the occurrence of feather pecking, toe pecking, back pecking and other bad habits of chickens. The light time of laying hens is 13-17 hours a day.

Provide enough clean drinking water

The first-born hen needs drinking water very much. Generally, a hen needs 100 to 200 grams of water every day. Therefore, laying hens must not be short of water every day, and brine can be supplied 2 to 3 times a week to improve the physique of laying hens and increase feed intake. You can also feed some carrots or green feed every day to improve the quality of eggs.
