Pollution-free layer chicken breeding technology

Production environment control

The external environment of the chicken house. In principle, the chance of interaction between the external environment and the cluster is minimized, and the external environment of the chicken house is controlled. The site selection complied with the following criteria: sunny leeward, well-discharged, dry and flat terrain; guaranteed adequate water supply, water quality up to the standard of public drinking water; building construction standards, try not to build on the basis of abandoned chicken farm; fully consider the perimeter of the chicken farm The protection of the environment from dust, excrement and other pollutants; the construction of the chicken house to save environmental protection, while meeting the three major requirements of sewage, fire prevention and epidemic prevention.

House interior environment. The interior of the house mainly includes the temperature and humidity inside the house. In order to ensure that the laying hens grow in a good environment, the hens are often housed in closed housing and ventilated regularly so that the air in the house meets the relevant national quality standards. In the temperature control, boiler collective heating can be used, this method is relatively low cost, suitable for continuous production of breeding farmers. In addition, drinking water systems must be regularly checked during the summer to avoid water leakage and increase chicken manure moisture to affect the home environment.

Production management

Brooding breeding period. Egg weight control occupies a very important position in the rearing and management of brooding. In the actual feeding and management, it is necessary to accurately grasp the time of eating, eat as early as possible, and control the standard and uniformity of body weight so that the birds can adapt to the new environment as soon as possible. In the actual feed, it should be strictly enforced according to the weight standard. When the chicken is below the standard weight, it is necessary to increase the amount of food. The increase is based on the fact that the body weight is 1% lower than the standard, but the total increase cannot exceed the standard amount of the next week; when the average body weight is higher than the standard, the current level is maintained. The amount of feed to body weight is close to the standard. Remember that in the brooding stage, the amount of feed must not be reduced, otherwise it will easily lead to poor growth of the hens and evenness will be reduced. In addition to weight control, it also includes regular temperature and humidity control, inspection of the health condition of the flock, timely excrement removal, and daily record of flock dynamics.

Egg production period. During the egg production period, it is necessary to ensure that food intake is controlled between 1 and 2 times per day. There are four kinds of feed preparation during the laying period, that is, the chicken age from 18 weeks to 5% egg production rate, the chicken age from 5% egg production rate to 42 weeks old, 42 weeks old to the elimination and high temperature season formula. The feeding in the feed tank should be uniform, the drinking water equipment should be cleaned regularly, and the chickens should be provided with sufficient drinking water. Observe the spirits and defecation of the flock at any time, and clean up frail, critically ill and dead chickens. In particular, it is necessary to pay attention to whether or not pheasants exist, and if they are found, they must be promptly treated or eliminated. In addition, do a daily production record.

In the environmental management, the ideal temperature of 21°C~23°C and the ideal relative humidity of 60%~70% should be guaranteed during the laying period, and sufficient lighting time and clean drinking water should be given.

Storage of eggs

The disposal of pollution-free eggs. First of all, the surface of the eggs to be disinfected, the most commonly used is ozone fumigation. Depending on the number of sterilized eggs, it can be done in a sealed container with an ozone generator placed in it and placed in an egg for 15 consecutive minutes to complete the disinfection process. The second step is to grade the eggs and select the quality or egg yolk color for grading. In the quality grading, eggs weighing 55g to 65g were classified as first-class eggs, and the rest were secondary egg packages. The yolk grading can be performed with Roche's egg yolk colorimetric fan.

The storage of pollution-free eggs. To ensure that the pollution-free eggs have a good storage environment, first store the eggs in the warehouse to be sterilized frequently, each time the eggs must be sterilized in the handover area, guaranteed twice a week. Commonly used disinfection materials include iodine preparations, chlorine preparations and the like. Second, control the temperature and humidity of the stored egg warehouse. In the temperature control, the longer the storage time of the eggs, the lower the temperature that the warehouse needs to set; in the humidity control, it must be controlled at 75% to 80% to ensure that the packaging box does not deform.
