Winter is the season when green feed and vitamin-rich feeds are lacking. To achieve high yields in first-laying hens, it is critical to master the following tactics:
Feeding eggs before feeding When eggs reach the age of 20 weeks, feed them before the eggs. The calcium content in the material is preferably 1% to 1.2%, and the crude protein content is preferably 16.5%. The whole refueling process should be completed gradually in half a month to prevent the refueling from causing the diseases such as laying hens to be diarrhea. After an egg production rate of 3%, the feed should have a calcium content of 3.5%, crude protein should be 18.5% to 19%.
While controlling the body weight of laying hens while reloading and supplementing calcium, it is necessary to grasp the control of the evenness of the flock development, and the large and small hens should be reared in groups and transferred regularly. Do not suddenly increase the material or sudden reduction.
The optimum laying temperature for laying hens is 18°C～23°C. When the temperature of the chicken house is too low and the feed is not increased in time, the laying hens will postpone production due to lack of energy, and even if they start production, production will stop soon.
Ventilation and humidity The humidity in the broiler house should not be too high, otherwise the chicken will suffer from filthy feathers, loss of appetite, sickness and illness, and delay the start of production. If the ventilation is poor, harmful gases in the air will increase, and the oxygen content will decrease, which will also make the reserve hen stunted and postponed production. Therefore, when the humidity of the hen house is too high, it is necessary to add more dry materials and proper ventilation to reduce the humidity.
The reserve hens that regulate the light-spring hatching usually enter the sexual maturity stage at the age of 15 weeks, and the natural illumination time during this period is gradually shortened. The time of light is short, and it takes a long time to reach sexual maturity. Therefore, after 15 weeks of age, supplemental light should be started to meet the needs of sexual maturity. The illumination time should be maintained at 15 hours of age, but the light intensity should not be too strong to prevent the occurrence of bad habits such as chicken feathers, toes, and stumps. The suitable illumination time for first-laying hens is generally 13-17 hours per day.
Feeding enough water to drink water is very important for the first-born hens. Generally, one hen needs 100-200 grams of water per day. Therefore, laying hens cannot be deficient in water. It is best to use flowing water tanks to supply water, and it can also supply 2 to 3 times a week. Light salt water to increase chicken constitution and increase feed intake. In addition, some carrots or green feed can be fed daily to improve the quality of the eggs.
