Chicken should pay attention to four problems, neglect easy to affect breeding benefits

In the process of prevention and control of avian influenza, we found that many chicken farmers often have some loopholes in the breeding process, resulting in low breeding efficiency, or even an outbreak of epidemic disease, resulting in losses.

I. the problem of site selection

Chicken farms should pay special attention to the distance from other chicken farms in addition to choosing places with leeward and sunny, high and dry terrain and convenient water and electricity. In the areas where broiler breeding is concentrated, there is a problem that the distance between chicken sheds is too small and the environmental pollution is serious. Some chicken sheds are only a few meters apart, and there are no isolation measures, which can easily lead to the spread of the epidemic. Some farmers have little awareness of epidemic prevention, and the chicken manure is piled up on the main road after it is cleared, which becomes a big source of pollution and poses a potential threat to their own chicken coops and other chicken sheds in the community.

II. The problem of implementing the all-in-all-out system

Many large-scale laying hens often raise more than two batches of laying hens at the same time. In order to keep the supply of eggs uninterrupted, they often buy the second batch of chicks before the first batch of laying hens are eliminated. Chicken sheds and venues cannot be thoroughly cleaned and disinfected, which can easily lead to disease in chicken farms.

III. Health system

Most of the farmers raise chickens at home, and the main labor force is both breeders and salesmen. Due to the weak awareness of epidemic prevention, they often visit each other, enter the chicken coop without disinfection, and there are no disinfection pools and other facilities at the door. In addition, after going to the market to sell chickens and eggs, they enter the henhouse without thorough disinfection. Some chicken farms dissect sick and dead chickens everywhere, or even eat sick and dead chickens, these behaviors bring great hidden dangers to raising chickens, and it is easy to break out epidemic diseases. Although most farmers pay more attention to the environmental control in the house, they ignore the environmental control outside the house. Such as sick and dead chickens discarded at random, mosquitoes and flies breeding and so on. In order to reduce the pathogenic microorganisms in the environment, regular disinfection of the environment in the field and disinfection of chickens in the house should be carried out regularly, cleaning up the sanitary dead corners in the field, eliminating mosquitoes and flies, eliminating breeding places of mosquitoes and flies, etc.

IV. Drug use

In terms of preventive drug use, some chicken farmers are not targeted and often give drugs uninterrupted throughout the feeding cycle, resulting in an increase in feeding costs and the emergence of drug-resistant strains. Once chickens get sick, it is difficult to control them effectively. After the disease of chickens, large doses (or insufficient doses) of antimicrobial and antiviral drugs are used without diagnosis, and the same "omnipotent prescription" is used almost no matter what disease it is, which not only increases the breeding cost, but also makes the chickens become drug resistant. In order to better control the disease, we should make a diagnosis at a competent veterinary station, use drugs reasonably according to the diagnosis of veterinarians, and strictly control the dosage and course of treatment.
