1Disinfection is not a joke

The correct disinfection behavior is“One cleaning, two washing and three disinfection”. That is, through the cleaning of feces and urine and the flushing of pollutants,99.9%It is correct to disinfect after the removal of harmful dirt. Otherwise, no matter what kind of disinfectant you choose, no matter how strong its penetration, or frequent replacement of disinfection drugs, it is wrong and ineffective. Because in addition to strong alkali, general disinfectants, even in contact with a small amount of organic matter (such as dirt, dust or feces, etc.) will quickly lose their bactericidal power. Such as: infectious gastroenteritis, epidemic diarrhea after the occurrence of pig feces containing high toxicity, when the piglets come into contact with feces, easily lead to the outbreak of the disease. Another example: piglets by sucking and licking sow skin and ingestion of E. coli in the feces is also an important cause of diarrhea in piglets. Therefore, the site should be kept clean before disinfection. Staff access, it is recommended to wear protective clothing, wearing a foot cover, to avoid the spread of bacteria.

2Ensure that the temperature is the lifeblood

For piglet diarrhea, the most important external pathogenic factors are cold, damp and unsanitary, and low temperature is the most important factor. For a successful pig-raising enterprise, it is necessary to have a good delivery room and its supporting nursery, and the ambient temperature is18℃~30℃between and can be regulated. Generally, piglets are afraid of cold and big pigs are afraid of heat. The enclosure should avoid high temperature and humidity, low temperature and high humidity. The temperature of the incubator is controlled30℃Above, the temperature in the newly weaned piglet house should be28℃Around, especially in the cold winter, it is necessary to strictly block the wind tunnel to prevent“Thief wind”To enter, set up heating, ceiling shed and other cold warm, so that the temperature is kept in a constant range; And to proper ventilation, exhaust odor, to ensure that piglets in a warm and comfortable environment.

3Air freshness is a condition

Ventilation is the core of air quality control in piggery. Most pig farms use natural ventilation, but it should be noted that the window hook should be well hooked to avoid“The window closes when the wind comes.”; The skylight of the closed pig house should be opened in time; in winter, it should be prevented“Through the hall wind”, four seasons to prevent“Thief wind”Wait. Mechanical ventilation is best taken”Longitudinal ventilation“This will help eliminate the dead angle of ventilation and reduce the number of fans. In addition, ventilation should be arranged in the most vigorous pig eating activities, usually timing switch exhaust fan ventilation.

4Basic immunity is the guarantee

Vaccination of pigs is an important way to reduce the occurrence of diseases.In the prevention of piglet diarrhea, we must ensure that the effective prevention of swine fever, foot and mouth disease, pseudorabies, mycoplasma, infectious pleuropneumonia and so on. Classical swine fever, foot-and-mouth disease, and pseudorabies are the foundations of the foundation. Other vaccines such as blue ear disease, vice pigs, stomach flow, Escherichia coli, etc. are reasonably selected according to the situation of the field, and there is no need to force them. In addition, attention should be paid to the correctness of the injection method, the type of vaccine, the effectiveness, the scope of use and the dose. To achieve the unity of vaccination and emergency vaccination, random and planned unity, so as to effectively prevent biological diarrhea,It is best to use before vaccination.ProbioticsReduce emergency response and enhance vaccine effectiveness.

5The management of sows is the premise

Sow postpartum in1Take a small number of meals during the week, the principle is from less to more, so that the possibility of indigestion is very small. The specific plan is: sow postpartum12～24In principle, no feeding or limited feeding within hours1Within kg, only warm bran salt soup is provided to promote appetite, accelerate the removal of placenta, and then add quantitatively every day. In short, lactating sows should be given full-price high-quality feed to ensure that their nutrition is comprehensive and balanced, so that piglets can obtain sufficient and nutritious milk. If the sow milk is too thick, milk fat and protein content is too high, piglets after eating indigestion; sow milk thin, nutritional insufficiency, lack of vitamins and minerals; can cause yellow and white scour piglets.

6Piglet nutrition is the foundation

According to the digestive physiological characteristics of weaned piglets, the key to prevent diarrhea is to select feed materials that are easy to digest and absorb, design scientific and reasonable formula, and prepare diets that are balanced in nutrients and easy to digest and absorb. The content of protein in the diet should be adapted to the growth stage of the pig.

Before and after weaning piglet feed appropriate supplement minerals, trace elements, vitamins, organic acids, compound enzyme preparations and probiotics, etc., can prevent the lack of nutritional factors of piglets, and can make up for the lack of endogenous digestive enzymes, maintain gastric acidity, improve the activity of pepsin, improve the digestibility of feed protein, promote the digestion and absorption of nutrients.

7,Prevention of diarrheais the key

Probiotics are recommended for piglets 6-12 hours after birth and are effective for up to 24 hours. prevention of piglet diarrhea,ProbioticsQuickly occupy the space, regulate intestinal health, increase feed intake, improve feed conversion rate, activate the animal's own immunity, reduce the use of antibiotics, and reduce mortality.

In essence, piglet diarrhea is also an adaptive response to the stimulation of intestinal infection and other intestinal stress factors. Of course, severe severe diarrhea will lead to dehydration, acidosis and electrolyte balance is destroyed, the physiological function of pigs will cause great damage. Therefore, the general principle for the treatment of diarrhea is“It should be dredged, avoid astringent blockage, replenish water, salt and resist infection.”That is to say, for mild diarrhea, diarrhea, clean up the stomach, antibacterial anti-inflammatory. For more severe diarrhea, drugs that inhibit gastrointestinal smooth muscle motility are considered, but emphasis is placed on fluid replacement, electrolyte replacement, and correction of acidosis, if necessary, intravenous or intraperitoneal injection. In short, in the course of the treatment of diarrhea, scientific medication, symptomatic and organic combination of treatment is very necessary, adhere to laxative, antibacterial anti-inflammatory, convergence, rehydration, strong heart, nutrition, heat preservation, stomach, anti-pressure and other comprehensive measures, the treatment of piglet diarrhea can achieve satisfactory results.

To sum up, the control of piglet diarrhea should have a long-term vision. In addition to sow health care, we should further refine the prevention and control measures. In addition to doing a good job in cold prevention and heat preservation of piggery and vaccine epidemic prevention, we should also take disinfection as a top priority. Details determine success or failure. Each employee of the pig farm should define his or her job responsibilities and achieve100%The implementation in place in order to effectively control the prevalence and occurrence of diarrhoeal diseases.
