The performance of laying hens is affected by variety, environment, disease and feeding management. The quality is pure, the environment is suitable, the disease is prevented, and the body quality, feeding and chicken are evenly distributed, and excellent production results will be obtained.
First, the gene: variety quality
The seedlings carry the genetic basis of the genetics, and the quality of the varieties is reflected by the quality of the seedlings. The quality of the seedlings is usually evaluated by the purity of the quality and the purity of the health. Pure quality means that the breed is pure and non-hybrid, and healthy and pure means strong and not carrying a bacterial virus. In actual business, it is often only concerned that the price does not pay attention to quality, and only pays attention to the quality of the body and does not pay attention to blood tests. Therefore, the choice of a good variety is the key: First, choose a big brand; Second, do a good job in the preliminary investigation and investigation; Third, conduct quantitative testing and testing.
Second, management: daily breeding
Feeding management affects all aspects of chicken production performance: management level is soft power, it takes time and practice to accumulate; human is the executive of feeding management; system, experience, motivation and emotion affect people's feeding behavior; feeding standard is feeding management Operational guidelines; body mass, feeding, and the number of chickens are the basic requirements for feeding management.
The uniformity of chicken body quality seriously affects the laying performance of chickens. The breeding process of young chickens should be guided by uniformity. The egg laying process should also pay attention to group uniformity. Feed nutrient levels should be in line with feeding standards, and feeding is more important. Feeding evenly during the feeding period can ensure uniform body quality. Even feeding during the laying period can ensure stable egg production. Feeding evenly can maximize the effectiveness of the feed, ensuring uniform feeding is a way to reduce the hidden waste of feed. Let the number of chickens in each small cage be the same, ensure that the quality of young chickens is consistent, and the feeding amount of laying hens is the same. The chickens are adjusted by each immunization, and the sick and weak chickens are selected in time by inspection.
Third, the environment: the process environment
The feeding process determines the production environment of the chicken. Due to scientific and technological progress and technological breakthroughs, the natural environment in the country has little effect on the production performance of laying hens. At present, the commercial laying hens are transforming from simple original low-density full-step to high-density laminated cages, open cages. Yangzheng is replaced by artificially regulated environment. The environment inside the house directly affects the performance of the chickens. The temperature and humidity are adjusted to the appropriate range to meet the minimum ventilation requirements. The control of harmful gases and dust in the house is done.
Fourth, health: disease prevention and control
Immunization and elimination of the disease are prerequisites for ensuring the performance of laying hens, and bacterial diseases and metabolic diseases cannot be ignored. The measures for disease prevention and control are to establish a system, comprehensive prevention and control, use both dead and live seedlings, repeat immunization, select poisonous type, cross protection, and close breeding in key seasons.
