Since the beginning of this year, the production of laying hens has been delayed. Most farmers do not understand the reasons, and the losses caused cannot be ignored. Most technicians don’t understand the details and fooling the farmers, even the young chicken farms don’t know how to dress up and guide them blindly. The delayed production of laying hens in autumn is more serious (on-time production time: 5% egg production rate is about 123 days , Those who exceed this time are postponed to start production) and it is normal to postpone the start of production for 2 to 3 weeks, which is very much, causing a direct loss of 4 to 5 yuan/piece. At the same time shorten the egg production 2-3 weeks, the egg loss is about 6-10 yuan / only. A job error and delayed production start-up will cause your profit to lose 10-15 yuan. Can you think about the loss?
Reasons for delaying production start:
1. The weight before the birth is not up to standard, and the chickens are lean.
2. After entering autumn and winter, the sunshine gradually shortens, and the light intensity gradually weakens, which stimulates the egg production of chickens to drop or part of the chickens to stop production. The performance of open and semi-open chicken houses is obvious.
3. After entering autumn and winter, the temperature gradually decreases, and the temperature difference gradually increases. It will also stimulate the egg production of chickens to drop or part of the chickens to stop production. The performance of open and semi-open chicken houses is obvious.
4, once pay attention to the temperature, ignore the problem of oxygen supply and ventilation, so that the frequency of egg production will be reduced!
Solution:
1. The weight before the birth is not up to standard, and the chickens are lean. It is necessary to ensure that the weekly weight gain reaches the standard during the 12 to 18 weeks of the expected delivery period to ensure the maximum development of the reproductive system.
2. After entering autumn and winter, the sunshine gradually shortens, and the light intensity gradually weakens, which stimulates the egg production of chickens to drop or part of the chickens to stop production. The performance of open and semi-open chicken houses is obvious. The solution is to grow out of shading and short light during the growing period. During the laying period, the lights are turned on one hour before sunset to increase the brightness. 3. After entering autumn and winter, the temperature gradually decreases, and the temperature difference gradually increases, which will also stimulate the egg production of chickens to drop or part of the chickens to stop production. The solution is to gradually close the chicken house, so that the chicken house reaches a controllable state, reducing the temperature difference between day and night. 4. Pay attention to the temperature once, and ignore the problem of oxygen supply and ventilation, so that the problem of frequent egg production will decrease! Negative pressure ventilation is adopted to allow dirty air to come out first, then fresh air before entering, and play a thermal insulation effect.
