Four kinds of common diseases of large-scale captive sheep

Sheep breeding is now relatively popular in livestock breeding, especially in some grassland and plateau areas, such as Xizang and other areas are large bases for raising sheep. Although the mode of raising sheep in China is mainly traditional grazing breeding, generally a small number of sheep are kept in captivity, and the number is not large, so the symptoms of sheep will be relatively small. However, once the number of sheep in captivity increases, the infectious ability of some diseases cannot be underestimated. Therefore, the loss caused by the expansion of the flock is very heavy and more. If it is not good, the whole sheep will be destroyed. We must pay attention to it. The following small series will tell you about the symptoms of these four kinds of diseases!

I. Sheep epidemic disease

1, sheep stomatitis

Sheep stomatitis is a disease that occurs on top of other symptoms, common in some traumatic diseases and toxic and fungal symptoms. Sheep generally suffer from this disease by eating some very sharp plant branches, oranges or eating ammonia by mistake, which is a strong alkaline food or water source.

2. Ruminal food accumulation

This is a kind of rumen full of a large amount of feed and produce, and these feeds do not digest, resulting in accumulation in the stomach, beyond the maximum volume of the stomach, resulting in the whole stomach distension, severe indigestion, this kind of situation may occur eating food for eating excessive coarse feed, such as some spoiled or moldy feed will cause this disease.

3, rumen gas

This kind of local saying is called flatulence, flatulence is mainly because there is grass fermentation gas formed in the belly of sheep, if not discharged in time for a long time will stay in the belly problems.

4. Intestinal spasm

Intestinal spasms are mostly caused by sheep overeating at high temperatures, and drinking cold water after eating or cold stimulation of the body, such as rain, will form cold air in the body, stimulate the lower abdomen to contract strongly, so that sheep are very painful.

II. Sheep epidemic

1. Anthrax

Anthrax is mainly caused by anthrax, and this disease has seasonal characteristics, in the spring and autumn changing weather conditions is the most likely to occur, such as digestive tract infection and mosquito bites are the way of infection, want to prevent it to do a good job of hygiene and cleaning, cut off the invasion source of bacteria.

2. Rapid sheep epidemic

The pathogen of sheep epidemic disease is Clostridium erodens, which is generally transmitted by digestive tract. It occurs most in low-lying pond and marsh areas. Tetanus can induce this disease. Prevention must be done well in the management of lambs and newly weaned lambs. At this time, their resistance is the worst, so prevention work is very important.

3. Sheep enterotoxemia

Sheep enterotoxemia also has a certain seasonal nature, generally in late spring and early summer incidence is the highest, during this period must not feed high egg white sperm, otherwise it will make the pathogen growth more rampant, breeding speed is faster, in the case of large weather changes is easy to cause sheep enterotoxemia virus breeding.

4, sheep sudden sniping

Sheep sniping is caused by the harm of type C Clostridium welchii. The infected group is more adult sheep. This disease belongs to non-contact infectious disease. It can be transmitted without some contact route. The mortality rate after suffering from this disease is very high. We must pay attention to it. After suffering from the disease, it will develop into peritonitis and ulcerative enteritis. As long as more observation is made, early detection and early treatment will avoid its worse development.

III. Parasitosis of sheep

1. schistosomiasis

Schistosoma is a parasitic disease, which can occur in a variety of poultry. Schistosoma has two types: acute and chronic. Generally, chronic schistosomiasis is common. Once infected, the acute body temperature can immediately rise to 40 degrees Celsius and higher. Animals have a common habit, that is, appetite will definitely deteriorate after the body temperature rises, so there will be loss of appetite. Slowly, mental problems will occur. Chronic type is mainly due to digestive function problems leading to rapid thinning of sheep, sometimes accompanied by diarrhea and vomiting symptoms, generally developed to two months away from death, we must add more prevention and management.

2. Fasciola hepatica

The temperature of the sick sheep will rise rapidly, and then gradually show diarrhea, abdominal distension and anemia, etc., and die within a few days. The acute mortality rate is very high, but the chronic one is wasting and dying after two months.

3. Front and rear disk fluke disease

The symptoms of this disease are mostly mental problems. The sick sheep have loss of appetite and general weakness. The mind is sluggish and motionless all day long. Once the worm enters the lungs, it will be life-threatening.

4. Cerebral polycephaly

The disease is a typical parasitic disease, this parasitic disease not only sheep, people will also be infected, the human body is also the parasitic object of this parasite, the worm body for a strip shape, the cyst will slowly grow larger and larger into the size of eggs.

IV. Common poisoning symptoms of sheep

1. Poisonous grass poisoning

This kind of situation is relatively rare in general large-scale farms. Generally, this kind of situation will not occur in well-managed farms. It is easy to occur in wild breeding, mainly because of eating poisonous grass or leaves of unknown plants by mistake. For example, oleander leaves are poisonous. Once eaten by mistake, they will be poisoned. It is best to check whether the breeding ground is safe before stocking to ensure that the grass is nontoxic.

2. Hydrocyanic acid poisoning

This disease is mainly caused by sheep eating flax seedlings or sorghum seedlings in large quantities. In addition, the content of hydrocyanic acid is the highest when the flax cake is squeezed by feeding machine, so the probability of poisoning is very high.

3. Cottonseed cake poisoning

Cottonseed and cotton leaves contain a substance called gossypol, which makes it poisonous. If cottonseed cake is eaten in large quantities for a long time, it is easy to be poisoned. Ruminants have better resistance to gossypol and detoxification ability, so the probability of poisoning will be smaller. Gossypol has an accumulation effect. If it accumulates in the body, it will attack.

The above are the four common diseases of large-scale captive sheep. We should keep in mind these symptoms and manifestations. At ordinary times, we should patrol the sheep pen more, observe the physical condition of the sheep, ensure that the first time to find the first time to solve the problem, and do a good job of prevention.
