Factors affecting the production performance of laying hens

Production performance of laying hens is affected by breed, environment, disease and feeding management. Pure quality, suitable environment, prevention of disease, and to achieve body quality, feed and chicken distribution evenly, will certainly achieve excellent production results.

? variety quality

Seedlings carry the material basis of variety inheritance. The quality of varieties is reflected by the quality of seedlings. The quality of seedlings is usually evaluated by quality purity and health purity. Pure quality refers to the purity of the breed, non-hybrid, healthy and pure refers to the health of bacteria without viruses. In actual operation, we often pay attention to price without paying attention to quality, and pay attention to body quality without paying attention to blood test. Therefore, it is the key to select good varieties: firstly, select big brands; secondly, do a good job in preliminary investigation; thirdly, carry out quantitative inspection and detection of indicators.

? Disease Prevention and Control

Immunization and prevention of group disease are the premise to ensure the production performance of laying hens, while bacterial diseases and metabolic diseases cannot be ignored. The measures of disease prevention and control are: establishing system, comprehensive prevention and control, both dead and live seedlings, repeated immunization, selecting virus type, cross protection, closed breeding in key seasons.

? process environment

The breeding process determines the production environment of chickens. Due to scientific and technological progress and technological breakthrough, the natural environment in all parts of the country has little impact on the production performance of laying hens. At present, the breeding technology of commercial laying hens is transforming from simple and primitive low-density full ladder to high-density laminated cage breeding. Open cage breeding is being replaced by artificial regulation environment. The environment in the chicken house directly affects the production performance of chickens. The temperature and humidity are regulated within the appropriate range to meet the requirements of minimum ventilation. Control and control of harmful gases and dust in the chicken house.

? feeding management

Feeding management affects all aspects of chicken production performance: management level is soft power, which needs time and practice to accumulate; human is the executor of feeding management; system, experience, incentive and emotion affect human feeding behavior; feeding standard is the operation guide of feeding management; body mass, feed and chicken quantity are the basic requirements of feeding management.

The uniformity of chicken body mass seriously affects the laying performance of chicken flock. The breeding process of young chickens should be guided by uniformity, and the laying process should also pay attention to the uniformity of population.

Feed nutrition level should conform to feeding standards, and feeding uniformity is more important. Feeding uniformity in reserve period can ensure uniform body mass, and feeding uniformity in laying period can ensure stable laying rate. Feeding evenly can give full play to the maximum effect of feed, and ensuring uniform feeding is the way to reduce hidden waste of feed.

Make the number of chickens in each cage consistent, ensure the consistent body mass development of young chickens, and the consistent feeding amount of laying hens, adjust the chicken flock through each immunization, and timely select sick and weak chickens through inspection.
