How are common chicken diseases treated? This chicken disease treatment manual explains it clearly
1. What causes a chicken to become paralyzed from being egg-bound and eventually die?
New hen disease: strengthen ventilation, provide multi-vitamin drinking water, treat enteritis, and support kidney function.
2. Newly laying hens pass sauce-colored droppings, have white spots on the eggshell, are off their feed, and production has dropped.
The white spots on the eggshell are caused by flock stress. As for the drop in production, there are many causes (stress, disease, feed, management, etc.). Conditions such as proventriculitis and enteritis also affect feed intake. You can provide astragalus polysaccharide in the drinking water, add microecological preparations to the feed to improve feed conversion rate, and provide multi-vitamin drinking water. Treatment plan for proventriculitis: antiviral, anti-inflammatory, and support kidney function.
3. Some 14-day-old laying hens have moist eyes with bubbles, some have eyelids stuck together, some have hard lumps protruding from the eye socket, and some have hard nodules on the upper beak. Is this fowl pox? If so, how should it be treated?
Fowl pox. Emergency vaccination with fowl pox vaccine, administer medication 12 hours later, using Chinese and Western medicine for antiviral and anti-inflammatory treatment.
4. How is proventriculitis in broilers treated, and to which drugs is it sensitive?
Antiviral, anti-inflammatory (penicillin class), support kidney function when necessary, and adding astragalus polysaccharide is more helpful for improving feed intake.
5. When hatching laying hens, how can the culled roosters be raised in large numbers? 1 is to use broiler feed and raise them according to broiler farming methods! 2 is to first use laying hen methods to raise frame chickens! At 70 or 80 days, use broiler feed to fatten them! Can you help me see which farming method is feasible? Or can you guide me toward a newer type of farming method?
Laying hen roosters do not need fattening. It is recommended to feed chick starter premix, formulate the protein level for the growing period according to production guidelines, and increase the animal protein content before financial considerations.
6. What causes visceral gout in three-day-old chicks?
There are many causes: dehydration, excessively high protein or calcium levels, and decreased kidney function caused by E. coli, etc.
7. What disease is it when dissection shows tracheal bleeding in chickens? Which disease should be considered first? What is it for broilers and laying hens respectively?
There are many diseases that cause tracheal bleeding, such as Newcastle disease, laryngotracheitis, mycoplasma, etc. For broilers, the key focus is respiratory complex.
8. A few days ago they had respiratory disease, and it has already recovered, but I found that in the past few days some chickens are laying white-shelled eggs, as white as paper, but not thin-shelled. May I ask, teacher, what is going on?
There are many causes: heavy medication leads to intestinal flora imbalance, decreased feed utilization, and relative vitamin deficiency; disease causes oviduct lesions. Measures: add microecological preparations, adjust intestinal flora balance, and provide multi-vitamin drinking water.
9. Introduced 3,500 sets of German Roman Brown breeding chickens, now 185 days old, egg production rate is less than 50 percent. Relevant experts tested and found it is oviduct hydrops in chickens.
Reproductive-type infectious bronchitis, infected within 72 hours after chicks hatch. This disease is not transmitted vertically through hatching eggs. Cull chickens with large red combs and oviduct cysts, reduce oviduct inflammation in the flock, and take measures to increase egg production.
10. 160-day-old laying hens: eggs weighing 35 grams account for 5%, eggshell color is whitish, egg white is not thin, many eggshells are broken, chickens are in good spirits, and egg production is 90%. What problem is this?
Protein determines egg weight, and low chicken body weight also affects egg weight; calcium was added too late (it should be at 105 days), calcium-phosphorus balance and content as well as utilization rate, disease and other factors can all affect the eggshell. Measures: increase protein and calcium content, add microecological preparations to the feed, adjust intestinal flora balance, improve feed utilization, and provide multi-vitamin drinking water.
11. Now there is a disease called proventriculitis. The veterinarian we invited said it is viral and already very serious. It has now been 30 days and they only average about 2 jin. We are very anxious. I want to ask what treatment methods there are and what its cause is. We discovered it when the chicks were 5 days old.
Proventriculitis generally develops after 20 days, with unsatisfactory feed intake, uneven size, and low feed conversion rate. Mycoplasma, fowl pox, malnutrition and other causes can all trigger this disease. Treatment plan: antiviral, treat the intestines, and support kidney function.
12. May I ask whether the laryngotracheitis vaccine causes a strong reaction in chickens, and if they are in the middle of an outbreak, can the vaccine still be given? This disease is now at its peak in our area. Are there any good treatment drugs?
The laryngotracheitis vaccine causes a relatively strong reaction. Cloacal application can reduce stress. Affected flocks must be vaccinated, and medication should be given 12 hours later: Chinese and Western medicine for antiviral, cough relief and asthma relief, and anti-inflammatory treatment.
13. What causes enteritis? What is the difference between coccidiosis and clostridial enteritis?
Coccidia, E. coli and other conditions can all cause enteritis. Large numbers of coccidia multiplying in the intestine lead to oxygen deficiency, which is suitable for clostridia growth and forms enteritis.
14. Can broiler coccidiosis vaccine and infectious bursal disease vaccine be given together?
Separate administration gives better results
15. How do you treat breeding roosters passing green droppings?
There are many causes of green droppings: Newcastle disease, E. coli, white comb disease, flora imbalance, etc. Treat E. coli and enteritis, then use microecological preparations to adjust the intestines.
16. The feathers on the chickens' backs have all been pecked off. May I ask what causes this? What methods can prevent and treat it?
Treat intestinal diseases, add microecological preparations to adjust intestinal flora balance, improve feed conversion rate; increase methionine content; strengthen ventilation and reduce density.
17. There are 60 Ma chickens, already two and a half months old. Recently I found five or six with feathers standing upright. Everything else is normal. May I ask what could be going on?
Increase nutrient concentration, especially ensuring amino acid balance.
18. When chickens are laying eggs, they are pecked to death by other chickens. What should be done? On average, one or two die every day.
There are many causes of vent pecking: poor skeletal development during the growing period leads to too narrow pubic bones; intestinal inflammation caused by E. coli or coccidia makes the oviduct narrow, causing prolapse, and then vent pecking. Treat according to symptoms: treat E. coli, coccidia or enteritis, provide multi-vitamin drinking water, and when eggs with blood are found, promptly remove that chicken and handle it separately.
19. Laryngotracheitis, I do not know what prevention methods or treatment drugs there are.
Laryngotracheitis vaccine at 35 days and 90 days by eye drop or cloacal application respectively. After onset, emergency vaccination with laryngotracheitis vaccine should be used, and medication 12 hours later: Chinese medicine for antiviral, cough and asthma relief, and treating the intestines.
20. What is the main difference between AI and ND?? Broiler crossbred chickens!!
AI mainly shows swollen head and face, swollen wattles, coughing, rales, screaming, white-green watery droppings, scales bleeding, decreased feed intake. Dead chickens have only two postures: one is fat chickens: before death they scream, jump high, die belly up, in good body condition and belonging to the fatter chickens in the flock. After necropsy, tracheal bleeding, blood phlegm or yellow caseous plugs blocking the bronchi, proventricular papillae suppurating, bottom bleeding, and intestinal bleeding; the other is thin chickens: dead thin chickens die lying prone, in poorer body condition. After necropsy, airsacculitis, pericarditis, and perihepatitis appear, and deaths show an increasing trend. The flock is listless. ND: the flock is listless, feed intake decreases, white and green watery droppings are passed, rales and coughing symptoms appear, with relatively high mortality. The chickens that die at 10-20% mortality are generally thin chickens, dying lying prone. After necropsy, proventricular papilla bleeding and swollen kidneys.
21. In the past three days the chickens have been found passing white watery droppings with soybean-sized red spots of feces. The coccidiosis medicine has been given continuously. May I ask what the cause is?
This situation is coccidiosis complicated by enteritis. During treatment, mix coccidiosis medicine with enteritis medicine, strengthen ventilation, and reduce humidity.
22. What generally causes feed-like droppings?
Feed-like droppings are generally caused by intestinal toxin syndrome or flora imbalance.
23. What kind of pathological process is enteritis? How to prevent and treat it? Which ingredient drugs are used? Also: is it good to treat some diseases with raw powder? Does it take effect quickly?
Enteritis is divided into many types: 1. Pathological diarrhea 2. Physiological diarrhea 3. Toxic diarrhea 4. Flora imbalance. No matter which situation it belongs to, drug treatment is needed first: the following ingredient drugs can be used for treatment: mequindox, amikacin, apramycin, colistin sulfate, etc. I do not recommend using raw powder to treat diseases, because current diseases are relatively complex and mostly secondary, concurrent, or mixed infections. They cannot be treated with a single therapy, and the plan should be comprehensive and integrated.
24. Salmonella, many people say that when they grow up the laying performance is poor. I do not know what to do.
Salmonella can be cured. You can use drugs containing mequindox ingredients and cephalosporin antibacterial drugs for treatment, while also using astragalus polysaccharide, vitamins, etc. If the disease is treated within a short period, strengthening early management will not affect egg-laying performance.
25. What should be done if laying hens get laryngotracheitis during the laying period?
For laying flocks infected with laryngotracheitis, it is best to use drug treatment directly. Vaccination is not suitable, because during this period it will cause stress and lead to a drop in egg production. Recommended plan: antiviral + antipyretic + anti-inflammatory + cough and asthma relief (integrated Chinese and Western medicine such as: ephedra + azithromycin or tylosin).
26. Which diseases can cause proventricular enlargement, and how are these diseases treated?
Diseases that can cause proventricular enlargement include the following: 1. Proventriculitis: treatment plan: antiviral, anti-inflammatory, antipyretic, and support kidney function; increase nutrient concentration, and raise chickens by size in separate groups. 2. Visceral Marek's disease: cull chickens. 3. Leukosis: cull individual affected chickens.
27. The chickens are now passing blue-green droppings (relatively dry). It has been a month and no chickens have died. They are now 120 days old. They previously had Newcastle disease and were vaccinated. I do not know the cause either. Will there be any major problem later? If so, what should be done?
Besides passing dry green droppings, are there other symptoms? Dry green droppings alone are not a disease. They are generally caused by stress or flora imbalance. Just adjusting with microecological preparations should solve the problem.
28. Since June this year, the chickens have had watery diarrhea that will not stop. Feed intake and drinking are normal, and egg production is normal. Antibiotics have shown no effect, and vaccine prevention has all been in place. They have now been laying for 5 months. May I ask the experts what I should do?
What is described is physiological diarrhea. It is caused by too high a content of crude fiber (bran) during the growing period, or by adding calcium too quickly. Ordinary antibiotics are basically ineffective for regulating it. The degree of diarrhea can only be reduced by reducing the bran content. You can choose some drugs specifically for physiological diarrhea and treat for more than 5 days. Then use probiotics to regulate the intestinal flora. After one course like this, it is basically improved. Usually, use microecological preparations for long-term regulation.
29. The chickens have occasional deaths. After dissection, the heart is wrapped in a white substance. The liver is enlarged. There is some white substance. The internal organs are foul-smelling. The droppings are watery. What is going on?
E. coli. Treat with cephalosporins or florfenicol, and also find the root cause that triggered the disease, treating both symptoms and root cause.
30. What is Arizona disease also called? How should it be treated?
Arizona disease is also called paracolon bacteria. Direct use of antibacterial drugs for treatment is sufficient.
31. Raising 2,000 chickens, from around 30 days the droppings gradually turned green, and by 40 days the whole flock had turned green. During this period I used two courses of E. coli medicine, all to no avail. Now at 43 days, feed intake is normal and there are no other symptoms. Anti-stress medicine was also used with no reduction. Several batches of chickens have been like this. I do not know the cause.
If it is dry green droppings, there are two possibilities: 1. Flora imbalance: just use microecological regulation! 2. Stress: caused by various stress conditions, regulate with vitamins and amino acids. If it is watery green droppings, there are several possibilities: 1. White comb disease or fowl pox, use a specialized treatment plan. 2. E. coli or intestinal lesions, treat according to symptoms.
32. I raised a shed of crossbred chickens. At 17 days, some blisters appeared on the chickens' thighs and wings, containing yellow fluid. After piercing them, purple blood flowed out. The chickens were not harmed. There were twenty or thirty per day. May I ask what causes this and how should it be treated?
If accompanied by pale combs, it can be judged as white comb disease. Treat with sulfamonomethoxine.
33. May I ask whether 40-day-old broilers with lame legs due to excessive streptomycin injection can be cured?
Use antibacterial drugs in drinking water; a portion can be cured.
34. Why do chickens dislike drinking most coccidiosis drugs containing sulfachloropyrazine sodium?
Please do not use it in concentrated form. Use the all-day drinking water method, and sugar can be added.
35. Young chickens: as soon as they arrived home I heard respiratory sounds, and after a few days there were more. I started using tylosin and Andike, and after using them continuously for a week there was no improvement. Possibly the tylosin dose was small. Afterwards, I increased the tylosin dose and used it with other antiviral drugs for 3 days, and it was basically cured. When egg production was 70%, individual chickens passed yellow-green droppings. The illness did not look very serious. After that, I cured it with poplar flower, Andike, Qintaike, Gante, and Rejian. Egg production remained at 80% and did not rise. Using various methods to treat oviduct inflammation also had no effect. Only on August 20 did I notice that many chickens had relatively large comb and flesh folds. I removed 200, and they laid very few eggs. The remaining ones maintained egg production at 93%. These removed chickens are not obviously roosters, but they have some rooster characteristics. May I ask, teacher, is this a matter of breed, or did the combs become larger after illness?
This disease is reproductive-type infectious bronchitis, infected within 72 hours after hatching, not transmitted through hatching eggs. Cull chickens with large red combs, and take egg-production-increasing measures for the remaining chickens.
36. I have just started raising some silkie chickens. Is it good to use the cages I previously used for laying hens? The bottom should be flat, right? Can I use ones with a sloped bottom?
You can use laying hen cages to raise them.
37. Small broilers got respiratory disease. I used tiamulin, and after poisoning I stopped the drug and no chickens died. Later I found symptoms of kidney-type infectious bronchitis. May I ask whether this is related to the tiamulin I used and thus caused it?
Kidney lesions can be caused by many situations: 1. Caused by disease (such as: kidney-type infectious bronchitis, bursal disease, etc.). 2. Caused by excessive drug dosage. The kidney lesions in this flock are not solely caused by a large drug dosage; they are related to kidney-type infectious bronchitis caused by the respiratory disease. Reduce stress and lower the protein level in the feed.
38. The chickens have just started laying, and the laying rate has reached 65 percent. When they first started laying, to prevent disease I had them use Wendukang. Afterwards several chickens were harmed. Most had a lot of blood around the vent. The doctor gave Daofule, cod liver oil, and Qingliang Yixia, but after all the medicine was used up, chickens were still being harmed. Almost every day 1-2 die, all still with the same symptoms, a lot of blood around the vent, and no egg binding. I do not know what is going on.
Is the blood on the chickens' vents fresh blood? There are two possibilities: one is caused by vent pecking. The second is caused by coccidia (in recent years laying flocks can also get coccidia).
39. Electrolytes are relatively bitter. Do they contain drugs? What are the main ingredients? If electrolytes are called sweet, do they contain glucose or other substances?
General conventional electrolytes will have carriers, and the vitamin content itself is not high! The sugar content is relatively high, and most of it is electrolytes.
40. Several chickens suddenly died, with the main symptom being swollen legs.
Staphylococcus infection, or stress from vaccination, trauma and other causes.
41. What are the symptoms of salmonellosis, and what temperature is best at 12 days? What disease is chest bleeding?
Salmonella can cause typhoid and paratyphoid, manifested as: intestinal disease. On necropsy, the liver is copper-green with yellow-white spots, the ceca contain yellow-white caseous plugs, and individual chickens become blind.
42. 138-day-old laying hens have paralyzed legs and are emaciated, have not yet started laying, and the intestines bleed slightly. Everything else is fine. May I ask what it is?
Proventriculitis. Plan: antiviral, treat E. coli, and support kidney function.
43. 37-day-old broiler breeder laying hens: earlier they showed decreased feed intake, which has now lasted 4 or 5 days. Now feed intake has dropped to 1/3. The flock is in very good spirits. A few have closed eyes, retracted necks, fluffy feathers, and pass egg-white-like droppings with yellow. A few also have white droppings (egg-white-like around the edge) and green droppings (in the middle). There is strip-like or dot-like bleeding on the lower legs. The jejunum shows soybean-sized irregular scattered bleeding points. The intestinal wall becomes thin. The rectum has needle-tip-sized spots arranged in a straight line. The cecal tonsils have bleeding points or bleeding patches. The bursa of Fabricius contains white lime-like exudate. The throat is bleeding with white phlegm. The trachea is bleeding and congested. What disease is this? Is it a mixed infection of bursal disease and ND? Can we avoid giving antibodies?
Bursal disease complicated by mycoplasma and enteritis. Conservative therapy can be adopted: transfer factor or Baijia, one bottle per 300 chickens once, combined with medication: Chinese medicine (astragalus polysaccharide) and Western medicine for antiviral, treating E. coli, cough and asthma relief, and supporting kidney function.
44. 150-day-old laying hens. They have had diarrhea for more than 10 days. It is said to be intestinal toxin syndrome. What medicine is better to use?
If diarrhea started right after they began laying, then it is physiological diarrhea, caused by adding too much bran during the growing period or adding shell too quickly. To treat this disease, first reduce the amount of bran added to the feed (try not to add any). Then use drug treatment, and after stopping the drug use microecological preparations to regulate the intestinal flora. If it is intestinal diarrhea triggered by infectious disease, directly use drugs for regulation, and after stopping the drug use microecological preparations for regulation.
45. Roman laying hens, 185 days old, current feed intake is about 95 grams. May I ask how to increase feed intake? Also, there are now sporadic deaths. Necropsy suspects intestinal toxin syndrome, and one had peritonitis. May I ask what should be done?
Treat enteritis and peritonitis, provide astragalus polysaccharide in drinking water, strengthen ventilation, lower house temperature, stimulate feed intake, and feed one extra meal at night.
46. The chicks got wet from rain yesterday. Today they are listless and will not eat. What should be done?
Raise the room temperature, place them near a heat source, prevent them from being crushed to death from cold huddling, provide multi-vitamin drinking water, and start feeding promptly after their down feathers dry.
47. A laying hen has a bloody hole on the sole of its foot and bleeds to death. What problem is this?
Disinfect the affected area with iodine tincture and apply a band-aid.
48. How long after vaccination can interferon be given? 3-5 days is sufficient.
