Several weeks before the new layer is laid, it is the transitional phase from the growing period to the laying period. At this stage, a series of work, such as group migration, selection and elimination, immunization, feed replacement, and increased lighting, will cause great stress on the chickens. Therefore, the hens have severe physiological changes, sensitivity, weak adaptability, and disease resistance. Poor performance, if not properly managed, can easily affect egg production performance. To this end, we must strengthen the management of feeding from the following aspects.
First, prepare for basket
The chicken house and equipment have a great influence on the health and production of laying hens. Before going to the cage, the chicken house and equipment shall be inspected and the feeding system, drinking water system, power supply lighting system, ventilation system, drainage system and cages, cages and other equipment shall be inspected carefully. Any abnormalities shall be promptly repaired; Houses and equipment are cleaned and disinfected. The steps are to clean the floor of the house, the excrement on the roof, walls, dirt, and dirt on the equipment. Rinse the house and equipment with high-pressure water, and spray the disinfectant solution after it is dry. Disinfecting, but also disinfecting the items used. In addition, prepare the necessary utensils, medicines, equipment, record forms and feed, and arrange the feeding personnel.
Second, timely transfer to the cage
1. Into the basket age: In the cage before the 16 to 17 weeks of age, so that the new hens have a period of time before opening to familiarize with and adapt to the environment, form a harmonious group, and have enough time for immunization and other work. If the cage is too late, the production time will be postponed and the egg production rate will be affected. The hens that have been put into production may also be discontinued due to intense stress caused by the transfer group. Even some chickens may cause yolk peritonitis and increase the number of dead birds. .
2. Election and Elimination: When entering cages, we must remove small-sized, thin chickens, and non-feeding residual chickens according to the variety requirements, and choose high-quality chickens that are spirited, healthy, and of suitable weight.
3. Classification into the cage: due to genetic and feeding management and other factors, there will still be some small chickens and larger chickens in the flock. If they are all eliminated, they will inevitably increase the cost. The cages in the egg house cannot be fully utilized, so When cages are kept, smaller and larger chickens are placed in different cages and special measures are taken to strengthen management and promote uniformity and tidyness. If the chicken is placed in a warm, sunny south-middle cage, it is appropriate to increase nutrition and promote its growth and development; over large chickens should be properly limited. According to the number of chickens accommodated in the cages, a sufficient number of cages per cage is provided at a time to avoid caged chickens that have entered the cage before they are bullied.
Third, pay attention to immunization
Before immunization, immunization is required. This immunization is very important to prevent the occurrence of epidemic diseases during the laying period. The immunization procedure is reasonable and in line with the actual situation of the field; the vaccine source is reliable, well-kept, and quality assured; the vaccination route is appropriate, the operation is correct, and the dose is accurate. After inoculation, the effect of inoculation should be checked, and if necessary, antibody monitoring should be carried out to ensure the effectiveness of the immunization so that the birds have sufficient antibody levels to prevent the occurrence of the disease.
Fourth, strengthen pest control work
Before starting production, we must do a good job of deworming. 110-130 days old chicken, 20-40 mg levamisole or 200-300 milliliters per kg body weight
Probiotics are a class of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, promoting nutrient absorption and maintaining intestinal health, resulting in the production of single microorganisms or mixed microorganisms with well-defined composition that are beneficial to health.
