Feeding management near peak egg production
Laying hens enter the due date from the age of 16 weeks and reach the peak of egg production at the age of 25 weeks. Whether the feeding and management status during this period is in line with the growth and development of the chicken and the requirements for laying eggs have a great influence on the egg production during the entire laying period. .
1 The group should be transferred in a timely manner. It is best to complete the work of vaccinating and repelling layered hens on time before the age of 18 weeks in order to make the chicken familiar with the environment as soon as possible. Too late to make part of the chicken has been discontinued production, or make the yolk fall into the abdominal cavity caused by yolk peritonitis. In addition to cages or cages, Newcastle disease oil seedlings plus live vaccines, inactivated egg drop syndrome vaccines and other vaccines should be inoculated. After entering the cage, it is best to conduct a thorough deworming work. The body parasites such as ticks and cockroaches can be sprayed with drugs. The internal parasites can be administered with albinoimidazole 20-30 mg/kg body weight, or with a Ding (wormbusting) in the mix. Trans-group, before and after inoculation should add a variety of vitamins, antibiotics to reduce stress response.
2 timely conversion of egg production in order to adapt to the increase in chicken body weight, reproductive system growth and the demand for calcium, can be laid at the age of 18 weeks to produce laying hens, 20 weeks of age from the beginning of egg production peak feed. At the same time, an additional amount of multiple vitamins is added to the material. During this period, the method of restricting feeding should be cancelled so that chickens can freely feed. There is always material in the tank during lamp ON.
3 Increase the light time The rural professional chickens adopt natural light in the breeding period. At the age of 18 weeks, if the chicken population reaches the standard, the light may be increased for 30 minutes every two weeks until the total number of light reaches 15 or 16 hours per day. If the chicken population is lighter and develops more slowly, it may be postponed to 20 weeks of age to increase the illumination time while increasing the feed. The principle of lighting during the production of eggs is that the time cannot be shortened and the intensity cannot be reduced.
4 to create a comfortable environment for chickens The most suitable temperature for laying hens is 13 °C ~ 23 °C, the best winter can be maintained above 10 °C, the best summer can be kept below 30 °C. Maintain indoor air circulation and prevent various noises. Keep the environment and feeding, drinking, lighting and other stability.
5 Do a good job of epidemic prevention and treatment
(1) Antibiotics such as norfloxacin, ciprofloxacin, gentamycin, etc. are added to the feed or drinking water after entering the cage. They are administered every 4 to 5 weeks for 1 week to prevent E. coli, Salmonellosis, and enteritis. Wait.
(2) Regularly adding multiple vitamins in batches in order to adapt to the chicken's egg production needs and reduce various stress responses to increase resistance to various diseases.
(3) Strengthen health management, implement reasonable immunization procedures, adhere to the chicken disinfection and environmental disinfection system, and prevent the introduction of the disease. Pay close attention to whether the rising rate of egg production complies with the standards and pay close attention to any minor effects of the external environment on the flock.
