What are the common diseases of meat sheep? A full analysis of prevention and treatment methods
In recent years, as market demand has grown, the sheep farming industry has also continued to develop, but along with it comes the occurrence of sheep diseases, especially highly infectious diseases, which are extremely contagious. Once an outbreak occurs, it rapidly spreads through the entire flock, and the mortality rate is extremely high, causing huge economic losses to sheep farmers. Below, Qinnong Network brings you the characteristics and prevention and treatment methods of several common diseases of meat sheep. Let's take a look.
1. Sheep braxy
Sheep braxy is an acute infectious disease caused by a pathogen entering the digestive system. Its onset is extremely rapid and the course of the disease is short. Affected sheep often die before showing any clinical symptoms, which is also the origin of its name. If the course of the disease is somewhat slower, the specific manifestations are reduced activity, unwillingness to walk, diarrhea, teeth grinding and convulsions, etc. After these symptoms appear, death can occur within a few minutes to a few hours. After the diseased sheep dies, the carcass rapidly decomposes and bloats. When opened, multiple necrotic areas are found in the stomach and intestines, with multiple areas of congestion and edema, and the intestinal tract is filled with gas.
Prevention and treatment methods: Its course of disease is extremely short, and after onset there is simply no time for treatment, so prevention is the main approach. Normally, strengthen epidemic prevention measures and vaccinate in a timely manner. In low-temperature cold weather, do a good job of cold protection and warmth preservation, avoid catching cold, avoid feeding frozen feed, and do not graze too early in the morning.
2. Pneumonia
Pneumonia is also an infectious disease. It is extremely contagious. Under conditions of low temperature, rainy weather, and a densely crowded flock, it is conducive to airborne transmission, and both its morbidity and mortality rates are high. After infection, the clinical manifestations in diseased sheep are high body temperature and fever, coughing, and fibrinous inflammation of the lungs and pleura
. It can occur in all four seasons, especially in the low-temperature seasons of spring and winter. Even after diseased sheep are cured, there are extremely strong aftereffects, and lung damage leads to extremely slow growth, causing economic losses.
Prevention and treatment methods: Adhere to self-breeding and self-raising. Strengthen management of introduced sheep and improve [quality]. Resolutely do not introduce sheep from epidemic areas. Sheep introduced from other places must first undergo isolation and quarantine, and only after ensuring they are disease-free can they be mixed into the flock for raising. Vaccinate in a timely manner. After disease is discovered, promptly isolate and treat, clean the pen sanitation, and promptly disinfect feeding utensils, then treat with drugs such as oxytetracycline and tylosin.
3. Sheep pox
Sheep pox is a febrile, contact infectious disease caused by viral infection. It can likewise occur in all four seasons, but is more likely to occur in cold seasons, and both morbidity and mortality are relatively high. The clinical manifestations of diseased sheep are body fever and pox all over the body, damaging the epidermal tissue of the sheep and destroying the body's protective barrier, making it easier for other pathogens to invade the sheep's body, and it often causes cross-mixed infections with other diseases.
Prevention and treatment methods: At present there is no complete treatment method. The main approach is prevention, supplemented by treatment. After onset, promptly isolate and carry out disinfection properly, and urgently vaccinate.
4. Foot-and-mouth disease
Foot-and-mouth disease is a common disease of many livestock. It is likewise an acute, febrile infectious disease. At onset, the sheep's body temperature can reach 40-41 degrees, and blisters appear in the oral cavity, tongue, and hoof areas. After the blisters rupture, the surrounding epidermal tissue sloughs off, forming erosions.
Prevention and treatment methods: Vaccinate regularly. When disease occurs, promptly isolate, carry out disinfection measures properly, and report to the relevant departments and handle according to relevant regulations.
