Scale farming precautions

Introduction: Several key links such as site selection, site disinfection, ventilation and ventilation, drug use, and disease in breeding farm management directly affect the effects of farming. To improve the raising and management level of chicken farmers, we take a look at Henan. Zhongzhou Animal Husbandry Equipment Co., Ltd. has been summing up the experience of chicken equipment for many years!

1. Reasonable site selection: The pollution caused by the intensive culture of chicken cages has a direct relationship with the location and size of the chicken house. Good chicken farm environmental conditions should ensure that the site has better microclimate conditions, which is conducive to the control of the air environment in the chicken house, but also to facilitate the strict implementation of health and disease prevention systems and measures. When choosing a coop, try to choose places that are close to farmland and vegetable fields and away from the suburbs. The terrain should be high-dry and sunny to shelter from the wind in order to keep the microclimate warm in the field area relatively stable so that excrement can be easily transported to farmland and vegetable fields. It is used in a timely manner, and the scale of cultivation is adjusted according to the amount of surrounding farmland, without causing the soil to accumulate too much phosphorus due to the large use of poultry manure. When designing a chicken house, it should also be considered that it is possible to maximize the separation of solids and non-solids from the feces so that the solids can be reasonably and fully utilized.

2. Disinfection of chicken houses and chicken farms: When fumigation and disinfection, the temperature of the homes should be at least 24°C, relative humidity more than 75%, and be closed for more than 24 hours. Low temperature and humidity are often not ideal for disinfection. When fumigation is performed in winter, it is necessary to increase the temperature and humidity in the house as much as possible. Disinfection with chicken sprays can reduce the chance of contamination of poultry, chicken equipment, ground, walls, and air. In addition, bacteria, fungi, viruses, etc. carried by the chicken's saliva, feces and other contaminants often mix into drinking water and feed, especially when the flock develops. The diseased chickens discharge the pathogens into drinking water through nose, nose, saliva, and feces. Causes the incidence of other chickens. Drinking water disinfection is to add appropriate water-soluble disinfectants in drinking water to kill pathogens in drinking water. Disinfectants that can be used for drinking water are mainly chlorine preparations, ion-blocking surfactants, and the like. When disinfectants are used to disinfect drinking water, they must strictly and accurately grasp the dosage and strictly follow the instructions for use of the product. They are not allowed to increase the concentration at random, increase the drinking time, and must not use drinking water for disinfection before or after 2 days of immunization. The environment, vehicles and personnel of the house are sterilized. A disinfection tank can be set up at the entrance of the chicken farm, and a channel or spray channel for installing an ultraviolet lamp can be set up at the entrance of the production area. Neighboring sheds, clean roads, dirty roads, warehouses, warehouses, etc. should be regularly spray-disinfected. Disinfection outside the home environment is as important as indoor disinfection. It is often neglected by chicken farmers and must be noticed.

3. Ventilation of the coop: The ventilation of the chicken house in spring, summer and autumn can be well done by most farmers. However, in the winter or the first 2 weeks of brooding, some farmers are afraid that the temperature of the broiler house is low and the doors and windows are tightly closed. As a result, ammonia gas and hydrogen sulfide concentration in the house are too high, and ammonia gas stimulates the respiratory mucosa, which can easily induce respiratory diseases. . In addition, closed doors and windows can also easily cause carbon monoxide poisoning.

4. Use of multi-vitamins, trace elements, and amino acids: Regardless of the use of premixes or concentrates, as long as the ratio of the feed formula provided by them is used to match the feed intake, vitamins, trace elements, amino acids, etc. The nutrients are full-priced and are fully capable of meeting the needs. Under normal circumstances it is not necessary to add another. However, some vitamins, trace elements, amino acids, and other additives can be used in the first few days of brooding, when changing groups, cutting off lice, using vaccines, and disease formation. Some farmers blindly added vitamins, trace elements, amino acids, etc., not only increased the cost of raising chickens, but also undermined the relative balance between various nutrients, resulting in metabolic disorders of the chicken body, reducing production performance.

5, to avoid stress: to strengthen feeding and management, try to avoid the crowd, noise, high temperature, high humidity, cold, density and temperature difference is too large and other artificial stress factors, so that when the disease does not turn the group, not immune, continue to collapse, not Refueling. Cold and heat stress can weaken the body's resistance, causing certain non-pathogenic microorganisms to cause disease. Cold and heat stress can cause frostbite, phlegm, heat radiation, sunstroke, bronchitis, pneumonia, and nephritis. Appropriate temperature and humidity favor the survival and reproduction of various pathogens and vector insects. Low temperature is more conducive to the survival of bird flu and Newcastle disease virus; hot summer is the season when mosquitoes, flies, cockroaches, cockroaches and other blood-sucking insects multiply, and the occurrence and spread of diseases can be caused by blood-sucking.

6, the use of antibiotics and antiviral drugs: normal prevention and treatment, the use of antibiotics, antiviral drugs can be. It is correct that the concept of prevention and prevention is the most important thing. However, some farmers use drugs to prevent them every day. They first use 3 to 5 days of antibiotics, then use 3 to 5 days of antiviral drugs, and then recycle and use antibiotics and antiviral drugs repeatedly. This not only increases the cost of raising chickens, but also destroys the normal bacterial flora in the chicken body. It also makes the pathogens produce drug resistance and reduces the chicken's own immune function, which is not worth the candle.

7. Selection and Use of Vaccines : Vaccine immunization strains should be compatible with the age of the chicken. For example, Newcastle disease II strain vaccines cannot be used for chicks up to 30 days of age and laying hens at peak (impacting growth and laying). . In vaccine immunization methods, there are generally nasal drops, eye drops, drops, subcutaneous injection of the neck, breast muscle and leg muscle injection, stabbing, anal coating and other methods. Different vaccines use the best immunization methods. For example, Newcastle disease IV strains and other attenuated vaccines have the best nasal drops and best eye drops. Newcastle disease I strains use the best intramuscular injection. The bursa of freeze-dried vaccines have the best droplets. It is best to gilt the roots of the fins. The oil emulsion inactivated vaccine is best injected subcutaneously in the neck. When attenuated vaccines are diluted, it is best to use normal saline or cold boiled water to dilute them. The diluted vaccines should be used within 4 hours and the remaining vaccines should be destroyed. When the attenuated vaccine is used to immunize with drinking water, it is best to use deep well water plus 0.3% to 0.5% skimmed milk, and use it after dilution. The vaccine-containing water should be consumed within 1.5 h. When using grease vaccines, it must be shaken, pre-warmed, and the vaccine must be used on the same day after it is opened.

8, disease prevention: In the feed by adding a certain amount of tylosin or enrozobine to prevent chicken mycoplasma disease. Every 4 weeks or so, add broad-spectrum antibiotics such as doxycycline and florfenicol to feed, and use them for 3 to 5 days to enhance the disease resistance of the chicken body. To prevent parasitic diseases, appropriate amounts of levamisole, avermectin and other drugs can be added to the feed. At the same time, we must carefully observe the flock, early detection, isolation, diagnosis, treatment of diseased chickens, proper handling of dead chickens.
