Problems of Laying Hens in Feeding Management

Breeding chickens should be transferred to the laying house at 18 weeks of age. Switching groups have an adverse effect on chickens. At this time, the transfer group can make the chickens well adapted to the new environment and good physique before opening. If vaccines such as Newcastle disease virus I are not vaccinated before the group is transferred, vaccination should be carried out in combination with the transfer group. Do not wait until the chickens are about to start production or have already started production. Before the start of production, we must also pay attention to two tasks: from the age of 19 weeks, we need to increase the light according to the production period. And be careful not to increase the length of light or the illumination is too large, otherwise it is easy to cause cloacal valgus in some chickens (commonly known as rectal prolapse), and at the age of 20 weeks when the bred chicken diet to egg production diet. After gradually increasing the light, the development of the reproductive organs of the chicken is accelerated. At this time, the weight of the chicken is still increasing. If the amount of the diet fed is insufficient or is not changed to an egg-producing diet when it is unwell, the nutritional needs cannot be satisfied, and the production of the chicken will be affected. Chickens will also appear after the chickens start production. If the amount of dietary quality that is fed is sufficient and does not increase the duration of sunshine, it is easy to cause over-fertilization of the chicken, which also reduces the production of eggs. Excellent laying hens, if properly reared and managed in the growing stage, develop normally, are usually seen at 20 weeks of age, and have an egg production rate of 5% at 21 weeks of age, and reach egg production peaks after 6 weeks, reaching peak egg production from the start of production. This is the period during which the egg production rate of the flock increases most in the weekly cycle. This period is the most critical period of the egg production period. All effective measures should be taken to ensure that the flock maintains good health and vigorous reproductive functions. Achieve the peak egg production. The level of peak egg production is often an important basis for estimating egg production throughout the year. At this stage, such as poor feeding and management or the incidence of flock, it will seriously affect the egg production during the entire production period. The main technical problem in feeding and management is how to create suitable environmental conditions so that the genetic potential of layer flocks can be fully expressed. The egg production level is a concentrated reflection of comprehensive technical measures that are closely coordinated in all production processes. Therefore, with a good and basically stable environmental conditions, the hens can achieve high yields and stable production. It is difficult for poorly-healthy chickens to have high egg production performance. For this reason, it is necessary to do a good job in preventing epidemics and disinfection and prevent pathogenic microorganisms from harming chickens. It is necessary to regularly eliminate weak and thin chickens that are likely to be hidden to facilitate the maintenance of the flock.
The daily feeding and management should pay attention to: the density of service should be moderate, each layer should have enough troughs, drinking fountains, and the location should be appropriate, often provide clean chickens and water temperature suitable for drinking water. Datong uses a chain feeder to feed it. Feeding should be done regularly every day. Attention should be paid to raising the nutritional level of the diet in time during the rising period of egg production. Also minimize egg contamination and breakage. Environmental conditions should be as stable or gradual as possible. The closed chicken house should be turned on and off on time so that the daily light time can be supplemented. In addition, the amount of ventilation needs to be adjusted according to the season, so that the temperature inside the house is more appropriate. The open chicken house should pay attention to sudden change to bad weather regulations: the impact on the flock. Regardless of the type of chicken house, appropriate measures for insulation or cooling should be taken to prevent cold and heatstroke, and to prevent the relative humidity and harmful gas concentrations in the house from exceeding the limit indicators, so that the chicken population can maintain a high and stable egg production level.
