CATDOLL : CATDOLL: What are the hazards of ammonia in chicken houses?

1. What are the hazards of ammonia in chicken houses?

Ammonia in the chicken house is produced by the decomposition of nitrogen-containing substances in feces and litter containing feces by microorganisms. The concentration of ammonia is related to the number of microorganisms and the retention of ammonia in the house. The lowest concentration that can be felt by the human body is 5.3x10. The allowable concentration of ammonia in the chicken house should not exceed 20x10. Excessive concentration will irritate the conjunctiva and nasal mucosa, causing tears, runny nose, inflammation of the organ epithelial membranes, and thus reduce the resistance of the chicken body. If the ammonia concentration exceeds 20xro and lasts for more than 6 weeks, it will cause upper respiratory tract inflammation and pneumonia, and egg production will decrease. Ammonia has a great impact on the weight gain of broiler chickens. Therefore, the ammonia concentration in the chicken house should be kept at least below 5xlo. A simple method to measure the ammonia concentration in the house is the ammonia test paper method. This test paper can easily measure ammonia in the range of sxlo-5ox10, which is convenient for understanding the ammonia level and

Determine ventilation volume.

2. What are the causes of hoof disease in dairy cows?

1. Improper or insufficient calcium-phosphorus ratio Under normal circumstances, the calcium-phosphorus ratio of dairy cows' diets should be 1.5 or 2:1. Too high a calcium ratio will affect the absorption of phosphorus, and vice versa, too high a phosphorus ratio will affect the absorption of calcium. Therefore, high calcium and low phosphorus or low calcium and high phosphorus in the diet will affect the absorption of calcium and phosphorus, leading to metabolic disorders and causing limb and hoof diseases. Zinc deficiency in dairy cows will affect the keratinization of the hoof and cause hoof diseases. 3. Unreasonable dietary structure The ratio of concentrate to coarse in dairy cows' diets is improper. Generally, the ratio of concentrate to coarse for high-yielding dairy cows is up to 60:40. If the ratio of concentrate to coarse is improper, too much concentrate will lead to excessive carbohydrate intake in dairy cows, and too much lactic acid will be produced in the rumen, causing acidosis in dairy cows and causing hoof diseases. Especially now that many cattle farms are giving dairy cows too much concentrate feed in order to increase production, and the amount of buffers used is not enough, it is more likely to cause acidosis in dairy cows and cause hoof diseases. 4. Environmental factors: The playground is too small and does not provide enough exercise space for dairy cows. The poor environment of the pen and humidity will reduce the anti-infection ability of the hoof cuticle and increase the incidence of hoof deformation and bacterial laminitis. The hard and uneven ground of the playground, with stones and cement floors, can cause damage or contusion to the cow's hoof. In addition, the feces cannot be cleaned in time, which creates a good opportunity for the reproduction of pathogens, which is easy to cause hoof infection and hoof rot. 5. Seasonal summer weather is hot and rainy, and dairy cows are under great stress and have reduced resistance. The hoof of dairy cows is soaked in sewage for a long time, the cuticle becomes soft, the infection rate of pathogens increases, and hoof disease is prone to occur. Feed is prone to secondary fermentation, acidity increases, and acidosis is more likely to occur, causing hoof disease. According to statistics, the incidence of hoof disease will gradually increase after May every year, especially in July, August, and September. The highest incidence is in the three months. 6. Genetic factors: Studies have found that the hoof shape of dairy cows is somewhat hereditary, and the offspring of dairy cows with bad hoof shapes are prone to hoof deformation.

3. What are the causes of psoriasis?

The causes of psoriasis are complex, but clinical studies generally find that the main causes are genetics, metabolic disorders, infection, immune dysfunction, etc. The main causes are genetic genes, infection, mental trauma, endocrine disorders, trauma, and the causes of psoriasis vary depending on one's own physical constitution, living environment, and the nature of work. In short, psoriasis is a disease with unclear causes, but treatment is very important.

4. What are the main diseases that chickens may get?

The main diseases that chickens may get are:

1. Viral diseases. Also known as infectious diseases, they can spread infections, such as Marek's, infectious Newcastle disease, avian influenza, infectious bursal disease, infectious bronchitis, infectious laryngotracheitis, infectious rhinitis, egg drop syndrome of laying hens, etc. Antiviral drugs (such as New Bird Quick, Antiviral Special, King Kong, Jinsi Ke Du Wang) should be used for treatment.

2. Bacterial diseases: caused by bacterial infections, such as Escherichia coli disease, mycoplasmosis, salmonellosis, etc., are treated with antibiotics (such as enterotoxin double-effect, clacillin, and saxanthocin, etc.).

3. Parasitic diseases. Caused by parasites, such as coccidiosis, chicken nematode disease, tapeworm disease, histomoniasis, etc. Coccidiosis is treated with anticoccidial drugs (such as strong coccidiostat or coccidiostat).

4. Nutritional deficiency. It is caused by one or several nutritional deficiencies, such as rickets caused by vitamin A deficiency; laying hens lay soft eggs and thin-shelled eggs due to calcium and phosphorus deficiency or imbalance, which requires vitamin A and D (emulsified vitamin supplement) treatment; feather pecking and hair loss are caused by amino acid deficiency, which requires amino acid (aminopeptide) treatment. 5. Physiological metabolic diseases, caused by physiological metabolism, such as fatty liver. Recover through conditioning. More details should be dealt with according to the infected chicken disease. It is best to focus on prevention, nutritional health care + disinfection health care, and treatment as a supplement. I wish you better economic benefits in breeding!

5. What are the types of serious diseases?

1: There are many types of serious illnesses. Serious illnesses refer to a type of disease that poses a serious threat to human life. The scope is very wide and covers multiple types of diseases. Serious illnesses include but are not limited to heart disease, cancer, stroke, lung disease, kidney disease, liver disease, brain disease, organ failure, etc. These diseases are serious and dangerous, and will have a huge impact on the patient's physical health and life. The purpose of critical illness insurance is to provide protection and financial support to cope with the risks brought by these diseases.

6. What are the diseases that cause internal bleeding in pigs?

Suspected eperythrozoonosis, swine fever mixed infection, it is recommended to see a veterinarian as soon as possible, do not delay

7. What causes hard crop disease in chickens?

According to your description, the chicken may have crop inflammation. Cause: The crop is filled with food and stagnates at the second esophageal opening under the crop, so that the food cannot be transported to the glandular stomach for digestion. The main symptoms of crop inflammation (swollen crop): dazed after not eating, fluffy feathers, and swollen crop. Some chickens have belching and vomiting. In severe cases, breathing difficulties occur, the neck is stretched and the head is shaken. If not treated in time, casualties will occur. Treatment method: Turn the chicken head down and gently squeeze the crop to make yellow mucus flow out of the mouth.

8. What causes soft crop disease in chickens?

Crop bloat is a common disease in chickens. Many chicken diseases can cause symptoms of crop bloat, which are manifested as swelling of the chicken's crop, refusing to eat, being filled with feed, gas and liquid, and having a sour and smelly odor.

1. Causes of crop distension in chickens include Newcastle disease, infectious bronchitis, pullorum in chicks, Candida albicans, indigestion caused by colds, moldy feed, foreign body obstruction, and coccidia.

2. Clinical symptoms: Sick chickens are listless, with ruffled feathers, decreased or no appetite, increased water intake, and dozing with eyes closed. The crop is filled with air, feed, and liquid, causing it to swell and protrude below the neck. In severe cases, light pressure on the crop causes yellow liquid to flow out of the mouth and nose, with a rancid smell. The head and neck are repeatedly stretched, swallowing is difficult, and the mouth is opened frequently. As the disease progresses, the digestive tract becomes disordered, and nutritional disorders cause rapid weight loss and death.

3. Diagnosis: Based on the clinical characteristic symptoms of the chicken's crop swelling, filling with feed, gas, liquid, etc., the diagnosis is chicken crop distension.

4. Prevention and treatment 4.1 Prevention Targeting various causes, prevention is the priority. Do a good job of disinfection and immunization at ordinary times, do not feed moldy and spoiled feed, feed regularly and quantitatively, create suitable temperature and humidity, and feed corresponding drugs for prevention when necessary to reduce the invasion of diseases. At the same time, add ingredients that strengthen the stomach and improve appetite to the chicken's diet, such as garlic, tangerine peel, chili pepper, pepper, fennel, etc., which can be found everywhere in rural areas. They can be added and fed for a long time. They can not only strengthen the stomach and prevent the occurrence of chicken bloated crop disease, but also make the chicken meat unique in flavor. 4.2 Treatment 4.2.1 Targeting the cause of treatment Targeting viral diseases such as Newcastle disease and infectious bronchitis, do a good job of immunization, and isolate and eliminate them in time when they occur. For bloated crop caused by Candida albicans in chickens, stop feeding moldy feed and feed with nystatin for 5 days. Feed doxycycline in drinking water for 3 to 5 days for white diarrhea in chicks. For coccidiosis, use chloramphenicol and amprolium cross-drugs for 3 days each. 4.2.2 Restricted feeding therapy Appropriately control the amount of feed intake and feeding frequency of chickens to reduce the occurrence of crop distension in chickens. 4.2.3 Digestive aid therapy Digestive aids include lactase tablets, dry yeast tablets, Jianwei Xiaoshi tablets, raw garlic, pepper, finger pepper, vinegar, sesame oil, white wine, Baicao Shuang, rhubarb soda tablets, etc. Among them, the Chinese patent medicine Jianwei Xiaoshi tablets have the best effect. 4.2.4 Water washing therapy Use a 20ml syringe to inject warm water into the crop from the mouth, lift the chicken upside down, so that the chicken head is facing down, and repeatedly squeeze the crop to discharge the accumulated food and water from the mouth. Repeat several times until the crop is empty. 4.2.5 Obstruction surgery therapy Surgery is taken for chicken crop distension caused by foreign objects such as feathers, plastic bags, and bamboo pieces. After the crop surgery site is plucked and disinfected, cut open the upper middle part of the crop, remove the accumulated obstruction or food, rinse with warm water, apply penicillin powder to the incision, suture with needle and thread, and disinfect with 5% iodine tincture. Stop feeding for 1 day after the operation, and feed easily digestible feed 2-3 days after the operation. I hope it helps you!

9. What are the symptoms of bursal disease in chickens?

Infectious bursal disease is an immunosuppressive, highly contagious disease that seriously harms chicks. The initial symptoms include some chickens pecking at the feathers around their anus, followed by diarrhea and white sticky or watery stools. Some chickens have slight tremors, stagger when walking, and unstable gait. As the disease progresses, the appetite decreases, the wings droop, the feathers stand upright and dull, and in severe cases, the heads of chickens hang to the ground, the eyes are closed, and they are in a state of lethargy. After 72 hours of infection, the body temperature often rises by 1 to 1.5°C, and then drops by 1 to 2°C. In the later stage, the sick chickens feel cold when touched. At this time, due to severe dehydration, the claws are dry, the eye sockets are sunken, and finally they die of extreme exhaustion.

10. What are the diseases and causes of low body temperature in dogs?

First, put a hot water bottle in the dog's kennel to keep the dog's body temperature from dropping. If conditions permit, cover it with a small blanket to maintain its body temperature and prevent the puppy from catching a cold. Touch the tip of its nose to see if it is moist. Before there is any major danger, you should take it to see a doctor to accurately understand its condition so as not to delay treatment. It's actually good now!
