Chicken coccidiosis has a wide distribution area and a relatively strong epidemic, which is a protozoal disease that seriously damages the chicken industry. The onset of the chicken population at the beginning of the emaciation, anemia, paralysis to the later stage of the casualty rate increased, many breeding friends in the early stage of the coccidiosis do not pay much attention, feel that the casualties are not very large, the late infection of coccidiosis chickens more and more, and finally the casualty rate continues to increase, to our breeding friends brought a lot of losses, so coccidiosis must be early prevention, early detection, early treatment. Next, I will give you an in-depth analysis of chicken coccidiosis, hoping to help our breeding friends and reduce the losses caused by chicken coccidiosis.
<h1 class = "pgc-h-arrow-right" > first, etiology</h1>
There are many kinds of Americles, including tender Amy Coccidioides, Poisoned Coccidioides, Giant Emmy's Coccidioides, Heap-type Coccidioides and so on. Among them, the pathogenicity of the tender Amy Coccidia parasitism in the mucosa of the cecal intestinal tract is relatively strong, called cecum coccidiosis. Other parasites within the mucosa of the middle of the small intestine are called coccidiosis.
<h1 class= "pgc-h-arrow-right" > ii. Epidemiology</h1>
Chickens of all breeds are susceptible, and chicks under 10 days of age are rarely protected by maternal antibodies. 20-50 day old chickens have high morbidity and mortality, and adult chickens are also sensitive to coccidiosis. Sick chicken manure is the main source of infection, and contaminated feed, drinking water, bedding, soil or utensils are all sources of infection. Flies, beetles, rodents, birds, people, means of transport, etc. can all become mechanical vectors. Poor feeding management conditions, wet and crowded chicken coops, poor sanitary conditions, vitamin A and K deficiencies in feed and unbalanced diet nutrition are all triggers for the occurrence of this disease.
<h1 class="pgc-h-arrow-right" > third, the main points of clinical consultation</h1>
1. Cecumcoccosis: the cecum is significantly enlarged, which can be 3 to 5 times normal, the intestinal lumen is filled with coagulated or fresh dark red blood, the cecum mucosa is thickened, and there are a large number of blood spots and necrotic foci.
2. Small intestinal coccidiosis: small intestine dilates, thickens, loses normal elasticity, the intestinal tube is dark red and swollen, there is coagulated blood or carrot-colored jelly-like contents in the intestinal tube, and there are a large number of bleeding spots on the surface of the mucous membrane, which are interspersed with the white dots of coccidiosis proliferation.
3. Mixed infection: the intestinal tube is enlarged, there are a large number of bleeding spots on the intestinal mucosa, and there is a large amount of purple-black blood with detached intestinal epithelial cells in the intestinal tube.
4. Chronic coccidiosis: mainly manifested as pallor of the intestine, loss of elasticity, and thickening of the intestinal wall.
<h1 class= "pgc-h-arrow-right" > fourth, preventive measures</h1>
1, keep the chicken coop clean and hygienic, coccidiosis most like the humid environment between 22--30 degrees is most conducive to the development of egg sacs, so we must control the temperature and humidity in the chicken coop, especially in the south of the wet time is relatively long, more should do the control of temperature and humidity in the house.
2, management should pay attention to the density of feeding should not be too large, timely cleaning of feces, the chicken coop with bedding should be replaced in time, to avoid the long time of bedding is easy to be infected with coccidiosis, as well as to keep the material tank and other utensils clean, frequent disinfection.
3. Reasonably set up drinking water equipment to avoid water leakage.
4. Reduce stress and enhance the body's immunity. During the high incidence of coccidiosis, anti-stress nutritional quick-supplements can be added to drinking water or feed.
5. Adult chickens are fed separately from chicks to avoid the spread of pathogens in adult chickens with insects, which will lead to the outbreak of coccidiosis in chicks.
Once the chicken suffers from coccidiosis, it will cause the growth of the sick chicken to be seriously hindered, and the weight gain and egg laying will be greatly affected. The disease has the highest incidence in chicks, and chickens at other stages can also have infections. Therefore, we must know what are the symptoms of chicken coccidiosis, how to treat chicken coccidiosis, and only by doing a good job in prevention and control can we ensure the healthy development of chicken farms and obtain the profits they deserve.
