Technology of raising chickens in rural areas: what are the causes of chicken glandular gastritis? How to prevent and cure?

Chicken adenomyogastritis is becoming more and more serious in rural chicken farms. Chicken glandular gastritis is an epidemic characterized by poor growth, emaciation, poor evenness, overfeeding and other appearance symptoms of poultry, which brings great economic losses to many farmers. So what is the cause of chicken adenomyogastritis? What are the prevention and control techniques?

What are the causes of chicken glandular gastritis?

Infectious factors

1, infectious anemia, adenovirus infection, reovirus infection, viral arthritis, vertical transmission, the above virus infection can lead to 3-day-old.

2. Proventriculus and Marek's disease can lead to disease in chickens after 50 days of age. Fowlpox, especially eye-type fowlpox, is an important cause of glandular gastritis.

3, unexplained inflammation, such as infectious bronchitis, infectious laryngotracheitis, ophthalmitis caused by vitamin A deficiency or poor ventilation, may lead to glandular gastritis.

Non-infectious factors

1. Biogenic amines and mycotoxins exist widely in feed, which can recover quickly after changing feed non-contagiously.

2. Helicobacter pylori infection can cause gastritis, gastric ulcer and gastric perforation, mostly in adult chickens and summer and autumn.

3. The disease is often complicated with ulcerative enteritis or necrotizing enteritis, which is related to the infection of anaerobic clostridium.

Second, how to prevent and cure chicken glandular muscle gastritis?

1. Prevention

(1) some chickens can develop adenomyogastritis after the first immunization, so more attention should be paid to it. The temperature in the chicken house should be raised in winter to prevent the occurrence of the disease.

(2) the occurrence of chicken adenomyogastritis is closely related to the mildew of feed, such as the accumulation of diet for too long, such as the mildew of fish meal, corn, soybean meal, vitamins, premixtures and so on. The diseased chicken farm must pay attention to the preservation of diet and do not apply mildew and deteriorate feed. All should be checked in advance to prevent chickens from getting the disease.

2. Treatment

Weibizhi 300 jin water / bag + acidified amoxicillin 400 jin water / bag, concentrated drinking water for 4 days.

III. Technical points of raising chickens in rural areas in winter

1. Protect against cold and keep warm

The cold and changeable climate in winter brings a lot of inconvenience to chicken production, especially the effect of low temperature on laying hens is very obvious.

In general, proper increase of feeding density, closing doors and windows, adding grass curtains, drinking warm water and stove heating can be adopted to keep the temperature of the chicken house between 3 and 5 ℃.

2. Moderate ventilation

In winter, due to the low temperature, the doors and windows of the chicken house are closed strictly and the ventilation is reduced, but the exhaust gas from chicken and the harmful gases such as ammonia, carbon dioxide and hydrogen sulfide produced by chicken manure fermentation still exist, which is easy to induce respiratory diseases of chickens. Generally can be a small area of ventilation, chicken house disinfection should be disinfected with peracetic acid, in order to neutralize ammonia in the chicken house. Therefore, it is necessary to deal with the relationship between ventilation and warmth, and remove the feces and sundries in the chicken coop in time. When the weather is better at noon, windows should be opened for ventilation to make the air in the house fresh and oxygen sufficient.

3. Reduce humidity

Controlling moisture in a chicken coop can sometimes be a big challenge in cold weather. Broilers, in particular, constantly add water to the henhouse, and the moisture of the cushion can be controlled only by exchanging the warm and humid air in the house with the cold and dry outside air. If the air exchange rate is too low, after a period of time, the cushion will accumulate water and produce more ammonia, as well as foot mats and leg problems. If the air exchange rate is too high, the chicken coop will become very dry, and the heating cost that we are concerned about will greatly increase. In winter, the ventilation in the chicken house is small, the water evaporation is reduced, and the hot air in the house will condense into a large number of water droplets when it comes into contact with the cold roof and walls, resulting in excessive moisture in the chicken house, creating conditions for the proliferation of bacteria and parasites. Therefore, we must strengthen management, pay attention to keep the chicken coop clean and dry, repair the damaged sink in time, do not add too much water, and it is strictly forbidden to splash water on the floor of the house.

4. Regular disinfection

Disinfection should run through the whole process of raising chickens. When the temperature is low in winter, the activity frequency of bacteria decreases.

However, the resistance of chickens is generally weakened because of the cold climate in winter. If disinfection is neglected, it can easily lead to an outbreak of disease. Especially bird flu, Newcastle disease, infectious bronchitis and other diseases, should be used weekly iodine preparation for spray disinfection of the chicken house, but the spray must not be aimed at the chicken body, so as not to catch cold.

5. Supplementary lighting

In winter, the night is long and the day is short, the laying rate of laying hens will decrease due to lack of light. In order to overcome this natural defect, artificial lighting can be used to make up for it. Under normal circumstances, the total time of illumination per day should not be less than 14 hours, nor more than 17 hours. For example, if the natural light during the day is 12 hours, artificial supplementary light is needed for 2 to 5 hours a day.

6. Increase energy

The chicken maintains its body temperature by getting heat from the feed it eats into the body. the lower the outside temperature, the more heat the chicken consumes to protect against the cold. It is determined that the feed consumption of chickens in winter is 10% higher than that in other seasons. Therefore, sufficient energy must be ensured in the feed of chickens in winter. in addition to ensuring a certain proportion of protein, high-energy feed with more starch and sugar should be appropriately added to meet the physiological and production needs of chickens.

7. Strengthen one's physique

As the resistance of chickens decreases in winter, special attention should be paid to the work of epidemic prevention and vaccination on a regular basis.
