Swine 5 disease refers to swine foot-and-mouth disease, infected with foot-and-mouth disease virus will get this disease. So how to prevent and treat foot-and-mouth disease in pigs? Let's take a look at what experts say. 1. Viewpoint: Many pig farms have a headache when it comes to disease 5. The main reason is that the harm of this disease has long been the most troublesome problem in pig farms. At present, the mainstream preventive measures are immune prevention. However, there are still many pig farms. Although vaccines are not omnipotent, it is absolutely impossible not to use vaccines. After all, for the 5th disease, the effectiveness of vaccine prevention is still recognized. 2. Cognition: Leaving aside the issue of vaccines, let's focus on the 5th disease stream.

Core tip: nutritional diarrhea is mainly caused by improper feeding and management, damp pig house, poor ventilation, no heat preservation in winter, no cooling in summer, sudden change of feed, lack of copper, iron, zinc, selenium in feed, etc., causing digestion and absorption disorders and diarrhea. Distinct the cause and treat the cause. 1 weaned piglets nutritional diarrhea etiology weaned piglets nutritional diarrhea etiology is very complex, a large number of studies have shown that the main factors of nutritional diarrhea are: vitamin deficiency, lack of mineral elements, feed crude protein content is too high, electrolyte imbalance. 1.1 vitamin deficiency Vitamin is one of the important nutrients for pigs, it

In pig production, it is often seen that there are a large number of even systemic bleeding points in the skin of pigs at various stages after the onset of the disease, which are more common in the neck, back and under the abdomen, medial thigh and medial axillary of pigs. So what is the reason for the emergence of these subcutaneous bleeding points in pigs? Here I write a personal point of view, hoping to provide some reference for the majority of pig people: a: mycotoxin poisoning mycotoxin poisoning has the characteristics of chronic poisoning! Can directly cause skin bleeding mycotoxins are mainly black grape ear mycotoxin (S-toxin). Bleeding spots appear on glabrous or less hairy skin sites. Another common clinical occurrence of skin bleeding

Blue-ear disease was first discovered in the United States in the 1980 s and had spread to some European countries in the 1990 s. An outbreak of blue ear disease in China in 2006 was followed by the isolation of highly pathogenic strains. Blue ear disease has a great impact on pig farms. The main symptoms are reproductive disorders, respiratory diseases, slow growth and increased mortality. At present, the origin of blue ear disease is unknown, endemic in most parts of the world and difficult to control. Transmission of infected animals through saliva, nasal secretions, urine, semen discharge virus, occasionally by fecal detoxification, late pregnancy infected sows can be excreted virus through milk. Pigs mainly through the nasal cavity, oral cavity

Swine stool dry knot (also known as intestinal constipation, intestinal obstruction, Chinese medicine called knot disease), mostly due to improper feeding and management or other diseases secondary to cause, to refuse to eat, thirst, stool dry hard, defecation difficult as the main characteristics of internal diseases. Pigs of all ages can occur, especially just weaned piglets, rural areas due to the lack of scientific feeding and management of large pigs and pregnant sows also often occur this disease. 1 the cause of 1.1 pigs eat a large number of dry hard, containing more debris, not easy to digest the roughage. Such as peanut shell, bean straw, sweet potato seedlings and other feed caused. 1.2 pigs are fed too high concentrated feed, insufficient drinking water, lack of exercise or sudden change of feed, change

Since autumn, many pig farms in the suburbs of Luohe City, Henan Province have distributed an infectious disease with elevated body temperature, anorexia, blood stasis under the limbs, ear tips and abdomen, skin cyanosis, dyspnea, neurological symptoms in piglets, and reduced reproductive performance in sows. After epidemiological investigation, combined with clinical symptoms, pathological examination and laboratory tests, it was diagnosed as Toxoplasma gondii complicated with eperythrozoonosis. The relevant diagnosis and comprehensive prevention and control are introduced as follows. 1 Epidemic and Incidence Situation Since mid-September, 320 pigs have been infected in more than 20 pig farms, with an incidence rate of 20% ~ 50%. The body temperature suddenly increased and was missed.

Porcine colibacillosis is a group of intestinal infectious diseases of piglets caused by pathogenic Escherichia coli. Clinically, it is characterized by enteritis and enterotoxemia. Swine colibacillosis is prevalent all over the world and is the most common infectious disease of piglets. Due to different serotypes and age of sick pigs and different clinical manifestations of the disease, it is clinically divided into three types of piglet yellow scour, piglet white scour and piglet edema disease. ① yellow dysentery of piglets-also known as early-onset colibacillosis of pigs. It is an acute highly lethal intestinal infectious disease that occurs within a few hours to a week after the birth of piglets. Clinically, it is characterized by severe diarrhea, yellow or yellow-white watery feces

The current epidemic of swine disease presents some new features. In the clinical aspect, mixed infection, atypical and bacterial diseases of swine disease increased. Some views on some new features and control methods of swine disease are presented. 1. the current new characteristics of swine diseases 1. old diseases such as porcine infectious pleuropneumonia and swine breathing disease. Although these diseases are distributed in a punctate pattern and the incidence is limited to a pig farm or a pig house, they are still the main infectious diseases that endanger the pig industry. 2. New diseases continue to increase in recent years, due to the introduction of new varieties, increased market flow, village and town trading markets and small pig farms epidemic prevention conditions are poor and other reasons, making pigs.

Blue-ear disease is one of the most serious diseases in pigs in recent years, and we must pay attention to its prevention and control. The main points of the diagnosis of the disease: the disease mainly occurs in pregnant sows and piglets. Sows show abortion, weak litter, stillbirth, mummified fetus, placenta difficult to peel off; limb ends, tail, nipple, ear tip cyanosis. Piglets appear elevated body temperature, shortness of breath, cough, movement disorders, joint swelling, ear tip to ear root cyanosis. At autopsy, the lung tissue showed diffuse interstitial pneumonia, swelling and sclerosing. Hemorrhage of hilar lymph nodes, marble-like change. Kidney swelling, there is a point. Prevention and control measures of this disease: First, adhere to self-reproduction and self-support. introduction

Corynebacterium causes inflammation of the pig's urinary system. The symptoms are purulent secretions from the sow's vulva and hematuria from time to time. According to the study of more than 80% of the boar foreskin with porcine Corynebacterium but the sow's vagina is rare. However, coryneobacteriosis occurs only in sows and usually develops symptoms 1 to 3 weeks after breeding or delivery, so it is likely to be caused by infection of the urethral orifice during breeding. Breeding boars, especially strong foreign breeds of boars, are cleaned regularly before mating or before prepuce and prepuce diverticulum to prevent transmission of germs to sows. Boar infected sows should arouse the attention of farmers. 1. pathogen characteristics rod

Toxoplasmosis (also known as toxoplasmosis) is a parasitic disease caused by Toxoplasma gondii of the genus Toxoplasma gondii, Toxoplasma gondii and a variety of animals and humans. The main clinical features are fever, constipation, dyspnea and central nervous system diseases, white foam in the nostrils, abortion of pregnant sows, stillbirth, pathological examination is characterized by severe pulmonary interstitial edema, lung, liver, stomach, lymph node enlargement. Mainly weaned piglets and adult sows with multiple infections. The general occurrence and prevalence are not seasonal, and typical lesions can be examined according to clinical characteristics and pathological examination combined with laboratory tests (ascitic fluid and pericardial fluid smear staining of sick pigs,

In addition to swine fever, swine flu, piglet paratyphoid fever, Haemophilus disease, diarrhea, in recent years, there are also epidemics of streptococcal disease, eperythrozoonosis and toxoplasmosis, which have produced some new diseases in summer. The changes and characteristics of the disease, so the diagnosis and prevention should be distinguished and paid attention. Here are several effective prevention and control measures: 1. pig eperythrozoonosis. Pigs of different breeds and ages were susceptible, and the morbidity and mortality of piglets were higher. The disease occurs in the summer, spread and blood sucking insects, especially pig lice. In addition, injection needles, surgical instruments, mating, etc. can also spread. Stress factors such as poor feeding tube, gas

Spring back to the earth, the recovery of all things, parasites are no exception, especially pig scabies, very difficult to eradicate. Scabies scabies is a common and frequently-occurring disease in pigs. The infection rate of pigs in large-scale pig farms is high, and there is an increasing trend year by year. Scabies mites parasitize in the tunnel dug by the insect body in the deep layer of the skin epidermis of pigs, causing red spots, pustules, scabs, cracks and other lesions on the affected skin. Due to the intense itching of the parasitic part of the mites, the affected pigs rub the corners and railings from time to time, causing skin blood flow, affecting appetite, slow growth, reduced disease resistance, and discounted feed remuneration.

The first option is to immunize the blue ear inactivated vaccine. After a large number of experiments show that the inactivated vaccine on the protection of blue ear disease is not strong, in the wild virus infection pressure or the body immunity decline when the epidemic is prone to occur, this immune method of pigs basically no protective effect. The second scheme is not immune blue ear vaccine, but with antibiotics to control mycoplasma and bacterial secondary infection, this method in the pig body immunity is normal, feed nutrition balance or short-term can control the outbreak of blue ear. However, once the pig herd is subjected to environmental pressure or stress, it may explode and spread at any time. The third option is to immunize the blue ear attenuated vaccine

Based on the current experience in controlling the disease around the world, the prevention and control measures include: appropriate active and passive immunization against co-infection sources, selective preventive dosing and treatment, and changes in production management measures. Because the pathogens and mechanisms of PCV-2-related swine diseases are not yet fully understood, specific control measures cannot be fully relied on. Only by carrying out effective comprehensive prevention and control measures at the same time can we achieve better results. 1, known co-infection source of immunity (1)PRRSV attenuated vaccine PRRSV inactivated vaccine antibody titer and maintenance time are not as good as attenuated vaccine, but the biological safety of attenuated vaccine
