Key points for autumn hens

Fall is the period for the first production of the reserve hens. How well the flock is fed and managed at this stage will directly affect the economic benefits of Chicken production. Therefore, in order to ensure the production performance of the hens, the following technical points must be considered: Replacement of the transition material for 20-week-old hens in exchange for feed before 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, when the egg production rate reaches 2% to 6%, the feed calcium should be 3.4% to 3.5%, with crude protein should reach 18%. To control body condition, while changing the transition material, it is necessary to grasp the evenness of chicken group development. It is best to keep the large, medium, and small reserve hens separately, so that the effect can be expressed after 3 weeks and do not rush. 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. The most suitable temperature for controlling egg production is 18°C. The temperature is too high or too low, and the nutrients needed to maintain the demand 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. Adjusting Relative Humidity The relative humidity of a chicken house is required to be 55% to 65%. After 4 weeks of age, the relative humidity can be reduced to about 50%. The humidity should not be too high. Otherwise, the chicks will suffer from poor appetite and frail health, thus postponing sexual maturity and postponing 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. Illumination adjustment and control The replacement hen usually enters sexual maturity at the age of 15 weeks. During this period, the natural illumination is gradually shortened, the illumination time is short, and the time for reaching sexual maturity is longer. Therefore, after 15 weeks of age, supplemental illumination should be started to meet the requirements. The need for sexual maturity in chickens. However, the light should not be too strong to prevent the occurrence of chicken embarrassment and licking. The initial illumination time of laying hens is 13-17 hours. It is necessary to ensure that drinking water supplies the first-born hen to drink water. Generally, a hen needs about 100 grams of water per day. Therefore, laying hens must not be short of water every day. It is best to use a flowing water tank for water supply, and 2 to 3 times of dilute salt water can also be supplied each week to improve the hen's constitution and increase its intake. You can also feed carrots or greens to increase protein levels.
