The early fall season is exactly the period of the first production of the reserve hens. The quality of feeding and management of chickens at this stage is directly related to the economic benefits of chicken production. Therefore, in order to ensure the laying hens' performance, the following technical management points should be made:
1, replace the transition material, to 20 weeks old hens for feed before the egg production, also known as the transition material. The calcium content of the feed was 1% and the crude protein was 16.5%. To gradually replace, in case of causing diarrhea, when the egg production rate reaches 2% -6%, the feed calcium should be 3.4% -3.5%, with crude protein should reach 18%.
2. Control the status of chicken groups. While changing the transition material, the uniformity of the development of chicken groups should be grasped. It is best to keep the large, medium, and small reserve hens separately. This effect can be expressed after 3 weeks. Do not Excessive urgency. The weight of light-weight chickens should not exceed the medium and large chickens, so as to avoid affecting sexual maturity due to fat deposition.
3. Strictly control the temperature of the chicken house. The most suitable temperature for laying eggs is 18°C. If the temperature is too high or too low, the nutrients needed to maintain the need will increase. When the temperature is lower than 13 °C, it will affect the growth and production of laying hens, so the broiler house temperature is too low, and not feeding in time, the chicken will be delayed due to lack of energy production. In the fall of high temperatures, the feed intake of laying hens is reduced. If the proportion of protein in the diet is not increased in time, it will affect the development of the chicken's reproductive system and delay the opening date.
4, adjust the relative humidity and ventilation, chicken house requirements relative humidity of 55% -65%, after 4 weeks of age can be reduced to about 50%, humidity can not be too high, otherwise the chicks will lose appetite, frail and sick, thus delaying sexual maturity, postponed Open production. 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 postpone the opening date.
5, control and adjustment of light, usually 15 weeks old hens into the sexual maturity stage, during which the natural light is gradually shortened, the light time is short, the longer the time to reach sexual maturity, and thus should begin to supplement light after 15 weeks of age To meet the needs of sexual maturity in chickens. Generally, the light hours at the age of 15 weeks, but the light can not be too strong, in order to prevent chicken feathers, licking and other anal fistula. The initial illumination time of laying hens is 13-17 hours a day.
6, for the clean drinking water, hens are very much needed for drinking water, usually a hen needs about 100 grams of water a day. Therefore, laying hens must not be short of water every day. It is best to use a flowing sink for water supply, and also to supply 2 to 3 times of dilute brine per week to improve the hen's constitution and increase its intake. You can also feed carrots or greens to increase protein levels.
