Prevention and treatment of glandular gastritis in Broilers

2018-05-08 17:48 Source:

In the aspect of broiler breeding, there are some infectious diseases characterized by poor growth, emaciation, poor uniformity of chicken flock, swelling of glandular stomach, shedding of mucosal ulcer and erosion of muscle and stomach. This disease has become a heart disease of the majority of farmers. Because of the different clinical symptoms and pathological changes of the disease, there are different opinions on the pathogen. This disease is known as infectious gonaditis. The following specific to understand: Broiler glandular gastritis comprehensive prevention and control measures, broiler glandular gastritis treatment program.

1、 Characteristics and causes of the disease
The age of onset of the disease was gradually advanced, and the symptoms of glandular gastritis had been reported in 2-day-old chickens. The course of the disease is long, easy to repeat, medication has an effect, stop the drug will relapse, some need treatment for more than 20 days. The disease spread vertically, and the effect of any disinfection method was not obvious. The etiology of the disease is complex, which can be summarized as follows.
1. Infectious bronchitis virus, infectious bursal disease virus, reticuloendotheliosis virus, chicken infectious anemia virus, reovirus, Escherichia coli, Salmonella, Candida and some anaerobic bacteria can lead to the occurrence of adenogastritis.
2. Eye type fowlpox is also considered to cause glandular gastritis in broilers. In the season of chicken pox, northern China usually occurs in autumn and winter, and this period is also the period with the highest incidence of adenogastritis. From the law of incidence, chicken pox first, then glandular gastritis, and then mixed infection of other diseases, and there is no effective drug for targeted treatment.
In broilers, the stomach gland was not well digested, and the stomach was not well fed.
4. The effect of mycotoxin. T2 toxin produced by Fusarium sp. is corrosive and can cause necrosis of glandular stomach, muscle stomach and feather epithelium; oospore toxin can make the annular surface of isthmus connecting the glandular stomach and muscular stomach become bigger and necrotic, and the mucosa is covered by pseudomembranous exudate; circular acid can cause glandular stomach enlargement, mucosal growth, and ulcer thickening, leading to the occurrence of adenogastritis.
2、 Preventive measures
It is necessary to strengthen daily feeding management and comprehensive prevention and control measures to prevent adenogastritis. To ensure the quality of chicken seedlings and prevent the vertical transmission of adenogastritis and other diseases, we should control the quality of chicken seedlings and introduce them from regular breeding farms. In addition, the feed should be kept in a dry place for 5 days. The broilers within 30 days of age were empty for 2 hours every day. After the broilers were empty, the glandular stomach and muscle stomach were emptied, which promoted the excretion of harmful substances accumulated in the glandular stomach and muscle stomach for a long time. Gastritis and stomach death can be prevented every day due to the stomach gland and the prevention of sudden death. For the sick chickens, cimetidine and aluminum hydroxide gel can be used to make acid and protect the surface of gastrointestinal ulcer from damage; penicillin and amoxicillin are used to control secondary infection; astragalus polysaccharide, dextran, mannan oligosaccharide and Fuzheng Jiedu powder can be used to improve the immune resistance and immune suppression of chickens.
There is no specific drug for the disease in the treatment of glandular gastritis, and there is no vaccine for the disease. This requires the feeding management personnel to do a good job in the immunization of other vaccines, and do a good job in daily sanitation and disinfection, improve the feed level, control mold infection, and take comprehensive prevention and control measures to effectively prevent the occurrence of glandular gastritis.

1、 The epidemic characteristics of glandular gastritis were as follows
1. The disease can be found in layers and broilers of different breeds and at different ages. The earliest onset of the disease can be seen at 3 days old and more frequently at 15-40 days old.
2. The disease can occur in all seasons of the year. It occurs frequently in autumn or in the alternation of seasons. The disease is more likely to occur when the temperature of brooding is low. It is caused by secondary E.coli, enteritis and Newcastle disease.
3. The occurrence of this disease is limited, and most of the chicken flocks come from the same chicken factory or breed.
4. The disease is a kind of comprehensive disease with complex etiology. When the feeding and management level is good, the disease does not occur or the incidence is mild. When there are inducements for the disease, there are symptoms of glandular gastritis. Often after each immunization or disease aggravation
2、 Clinical and pathological changes of glandular gastritis in broilers
Clinical changes: the latent period of the disease only showed slow growth and drowsiness. In the late stage of infection, the symptoms of respiratory tract were depressed and chilly. In the middle and late stage of infection, they were depressed and afraid of cold. After closing their eyes and standing still, they quickly dodged after being frightened. Their wings drooped and their feathers were irregular. Their food intake and drinking water dropped sharply. The feed conversion rate was low. The excretion of white, yellow green, fish intestines or tomato like feces was discharged. There was undigested feed. The progressive weight loss of sick chickens showed a negative growth trend with different sizes. The course of disease was 8-10 days, and the peak of death was 4-6 days.
Pathological changes: the dead chicken was emaciated, the nipple was swollen and everted, the base of nipple was pink, and there were blood and ulcer around it. Some nipples fused, unclear boundaries, late perforation, ulcer depression disappeared, muscle stomach shrinkage, thymus, pancreas, bursa of Fabricius atrophy, part of the kidney swelling, intestinal swelling, hyperemia, dark red intestinal wall eversion, late mucosal shedding, fragile, thin, nothing, intestinal hemorrhagic enteritis.
3、 Treatment plan
Scheme 1: use jigaitai drinking water, a special drug for glandular gastritis produced by jiuruiyuan company. This medicine can be used for muscular glandular gastritis caused by all causes. The swelling of glandular stomach subsides in 2 days, yellow manure and red feces (which seriously affect digestive function) are eliminated, and the food intake is increased. It can be cured for 4-5 days
Scheme 2: for areas with high incidence of adenomyogastritis: 1-10 days old, no signs of muscular glandular gastritis were found within 20 days. The color of stool, growth rate and food intake began to be normal

Chicken clinical manifestations: in the early stage of the disease, the chickens were excited and ran wild, and their food intake decreased or abandoned. There are heterophilic performance, such as licking soil or chicken manure and other debris; some chickens have symptoms such as piling up on the wall of the house, standing still with closed eyes, mouth flowing sticky saliva, fear of cold, feather inversion and other symptoms, and large groups are squeezed into a pile at the corner of the chicken house to be warm; the skin of sick chicken legs is dry, the color becomes pale, and the touch is cold; the growth speed of chickens is slow or stagnant, which leads to serious uneven uniformity of the large group; and The feces of the flock were soft and strip-shaped, with undigested feed residues in it. The incidence rate was very fast. At the beginning, only a few chickens were wilting. After two or three days, it could develop to more than half of the whole group. In addition, large groups of food intake will immediately drop to a very low level, chronic patients due to high malnutrition, and eventually consumption failure and death.
The symptoms of autopsy of sick chickens: massive bleeding or congestion of intestinal mucosa, swelling and bleeding of caecum lymph nodes, swelling and thickening of glandular stomach wall, severe spherical shape, and hard glandular papilla edema. When scraped with a blade, it has serrated resistance feeling. The cuticle is easy to fall off, and the local area is white gelatinization. In serious cases, keratin ulcer corresponds to intramuscular hemorrhage, intestinal tube becomes thinner, and intestinal mucosa increases in the early stage It is thick, later fall off, intestinal bleeding, intestinal wall thinning.
Broiler glandular gastritis treatment program: use jigaikang drinking water, 100 grams of water 300 Jin, a concentrated dose of the whole day, continuous use of 4-5 days, can be completely cured.
