- Causes reproductive disorders in sows, slow or stagnant growth of piglets, formation of stagnant pigs, death of all kinds of pigs, and huge economic losses;

- Make the general morbidity rate of pigs in 30% to 70%, and the morbidity and mortality rate in 10% to 30%, or even higher;

- Causing pigs to prolong the time to slaughter for 10-30 days, the decline in production performance, the elimination rate increases, or a large number of deaths;

- And if there is a mixed infection, the death rate increases and is easy to repeat.

Secondly, analysis of pig respiratory disease repetition

1、Complex and variable disease condition

It is common that multiple pathogens are mixed infection, such as virus and bacteria mixed infection, virus and virus mixed infection, bacteria and bacteria mixed infection. At the same time, in addition to respiratory morbidity, the digestive system, immune system and other systemic multi-system also morbidity. The disease spreads quickly in the group, and there exists cross transmission from sows to piglets and from fat pigs to nursery.

2、Pathogenesis

2.1 Blue ear disease is the main factor of pig respiratory disease.

Respiratory diseases are mostly mixed infections, including porcine blue ear disease, circovirus type II, Mycoplasma hyopneumoniae and contagious pleuropneumonia are the main diseases, and blue ear disease is one of the core factors. Although the symptoms of blue ear disease alone are not very serious, and the lethality is not very high, but the persistent infection and immunosuppression caused by blue ear disease, leading to other disease infections will bring serious consequences.

2.2 Immunosuppression is a key factor in the frequent incidence of respiratory disease

The key factor in the high frequency of respiratory diseases is immunosuppression. On the one hand, immunosuppression leads to low immune function, lack of immune response, slow production of antibodies after vaccine immunization or inability to produce enough antibodies, resulting in low antibody levels and inability to resist viral (e.g., swine fever, blue ear disease, pseudorabies, etc.) infections. On the other hand, the poor overall resistance of the organism causes the development of conditionally pathogenic bacteria, such as Mycoplasma, Haemophilus parvovirus, Pasteurella, Streptococcus and so on.

So, once these situations (hazards of respiratory diseases) occur in pig farms, how should we carry out timely and effective treatment and therapy? First of all, let's make a full understanding of swine respiratory diseases, which will help to provide a reference for timely diagnosis and prevention of the disease.

3.Thirdly, how much do you know about pig respiratory diseases?

1、 The epidemic characteristics of the disease

Pig respiratory disease is a kind of mass disease, mostly mixed infection, with the characteristics of fierce, fast infection, wide popularity, great harm, easy to repeat. Sometimes it’s local epidemics, and more frequent during cold season, the incidence of winter can reach 30% ~ 80%, mortality rate of 5% ~ 3 0% or more, mainly in the late nursery and growth and fattening period, especially in the 13 ~ 15 weeks of age and 18 ~ 20 weeks of age.

2.Pig respiratory disease determination in winter

Sick pigs are depressed, love to pile up, reduced appetite, slow growth, wasting, rough fur, abdominal breathing, shortness of breath, dyspnea, coughing and so on. Some sick pigs continuous coughing and even prolapse of the anus, acute onset of pig body temperature individually appeared temperature rise above 40 ℃, conjunctiva redness, increased secretions, Cyanosis of the skin of the ears and abdomen in the later stages, heart failure, the above can be initially determined as winter respiratory diseases.

At the same time, according to relevant statistics, 60% of the disease loss for pig farms come from respiratory diseases, as the saying goes, “outside does not cure ringworm, inside does not cure asthma”, indicating that respiratory diseases have been the difficult point of disease prevention and control in pig farms. And through the above characteristics of disease prevalence shows that pig respiratory disease mainly occurs in the late nursery and growth of fattening period, and fattening pigs is the main body of the economic benefits of pig farms, at the same time, fattening stage of the breeding cost accounted for a larger proportion. Therefore, to reduce the infection rate of respiratory diseases in winter fattening pigs, and to improve the management of fattening pigs is to increase the efficiency of pig farms “icing on the cake”.

The following is the winter fattening respiratory disease control program for you to organize, we hope to help you solve the winter pig farm respiratory disease problems

4.Fourthly, do a good job of winter pig farms fatten, in order to be less likely to relapse

On the winter fattening pig respiratory disease control methods, we prepare a video explanation, click on the video below to watch directly.

Detailed prevention and control recommendations, please browse the text below↓↓

Establishment of a rational prevention and treatment program to prevent secondary diseases

★ Product effect

1.Miarom: pure natural plant essential oil additives imported from Germany McElwee, which can effectively strengthen the lung function of livestock and poultry organism and reduce the occurrence of respiratory diseases in livestock and poultry.

2.Circolin: Germany McElwee original imported special swine “health care products”, can be a very good prevention and treatment of swine viral infections, and comprehensively improve the immune health of animals to promote the performance of reproduction and growth to play. Repair immunity, body antioxidant, protect the liver and kidney, strengthen metabolism, at the same time can eliminate immunosuppression in pig farms, rapid rehabilitation of blue ear, round ring and other diseases.

3、Sporezyme-Plus: Korea imported composite heat-resistant micro-ecological animal additive preparation, can significantly improve the intestinal health of fattening pigs, increase feed intake, reduce the feed-to-meat ratio, and shorten farrowing time.

2、Comprehensive prevention and control measures

◆Strengthen the feeding management of pigs to improve the resistance of the body.

According to the nutritional needs of different herds, rationally supply comprehensive and balanced nutritional feed to ensure the growth and development of pigs.

At the same time, in the management of pigs, different groups of pigs should be reasonably divided into groups, and reduce the feeding density of pigs as much as possible; often keep the pig house dry, clean, hygienic, pig house, utensils and the environment disinfection on a regular basis, pay attention to the heat preservation of the pig house and ventilation, in order to improve the quality of air in the pig house. The implementation of the pig production of various stages of the whole and whole out of the rearing mode, so as to reduce or avoid the opportunity of infection of pig respiratory diseases.

◆ Adhere to selfpropagation and selffeeding to prevent hidden infected pigs from bringing in pathogenic bacteriaAdhering to selfpropagation is the key measure to prevent the hidden infected pigs from bringing in pathogenic bacteria of swine respiratory diseases.

When pig farms need to introduce breeding, they should go to the breeding farms without infected areas, and carry out immunization in strict accordance with the procedures. After the introduction of breeding pigs, they should be isolated from the production area for more than one month, and after the quarantine is determined to be negative, they can only be fed into the farms and establish a strict veterinary hygiene and disinfection system, and often keep the pig sheds clean, hygienic and dry, and they should choose the new type of disinfectant drugs to do a good job in disinfecting the pig sheds and the surrounding environment.

◆ Immunize pigs well in advance. Prevention of pathogenic swine respiratory diseases

Adopting scientific and reasonable immunization program and monitoring the effect of vaccine immunization, detecting and eliminating the hidden strong virus carried by pigs, and doing a good job of disinfection are important measures for preventing and purifying swine respiratory diseases.

Reasonably formulate the immunization procedures of swine herds, immunize and vaccinate the swine herds with swine pseudorabies, swine blue ear disease, swine infectious pleuropneumonia, swine circovirus disease, swine atrophic rhinitis, swine pneumonic disease, swine paratyphoid fever, parvovirus, swine streptococcus weakly virulent bacterial or inactivated vaccine, inactivated swine mycotoxin vaccine and swine mycotoxin pneumonia rabbiting weakly virulent vaccine at an appropriate time, in order to control the pathogenic factors that cause the swine respiratory tract diseases.

◆ Prevent swine mycotoxin poisoning induced swine respiratory diseases

Control the humidity and storage temperature of feed to prevent mold and deterioration of feed and find the moldy feed in time; if the feed fed to pigs is contaminated by mycotoxin, the moldy feed should be stopped immediately.

For the occurrence of different degrees of feed mold, can be fed to the pigs before the sieve, and the toxin is the most concentrated grains, worm erosion particles removed, but also in the feed to add mycotoxin adsorbent (such as MiaBond) to help adsorption of feed and pigs in the body of the accumulation of a variety of toxins, in order to reduce the chances of mycotoxicosis and other diseases caused by mycotoxins in swine herds.

◆ Timely deworming for pigs to prevent parasites from causing swine respiratory diseases

General piglets at about 45 days of age, frame pigs at about 90 days of age and fattening pigs at about 135 days of age, these three stages are susceptible to swine parasites, can be mixed in the feed deworming of pigs. Sows can be mixed in the feed deworming 4 weeks before delivery or 2 weeks before delivery to block the vertical infection of parasites in the fetus. Reserve sows can be mixed in the feed deworming one month before breeding to effectively prevent parasitic diseases caused by swine respiratory tract diseases. Preventing parasites from causing swine respiratory diseases.

In the high incidence stage of disease, besides doing the above work, pigs should be observed every day. Once the pigs are found abnormal, deal with them in time. Starting from the feeding management of pig farms, timely “check and fill in the gaps”, adhere to the principle of prevention and control! It can effectively reduce the chance of avoiding or lowering the occurrence of diseases.
