How to Treat Pig Cold Diarrhea? Detailed Explanation of Treatment Methods

The root cause of the pig "cold diarrhea" disease has now been confirmed to be infection of pigs with transmissible gastroenteritis and epidemic diarrhea, and pigs are prone to this disease when the weather turns cold. Once a pig contracts this disease, in addition to severe diarrhea and death of pigs (the mortality rate of suckling pigs can reach as high as 100%), it also seriously affects pig growth and causes an increase in the culling rate of pigs. In order to effectively control the occurrence of this disease, the pathological characteristics and prevention and control measures of the disease are introduced as follows:

Pathological characteristics

Porcine transmissible gastroenteritis and porcine epidemic diarrhea are highly contagious viral diarrheal diseases that can infect and cause disease in pigs of all ages, especially piglets within 10 days of age, whose morbidity and mortality rates are both very high. (Huaxia@#@227@#@Network) The main symptoms of affected pigs are vomiting, severe diarrhea (watery diarrhea resembling spraying) and dehydration. In addition to affected pigs, the virus contaminates feed, drinking water, air and other media and then infects pigs through the respiratory tract and digestive tract. Other factors such as poor feeding conditions, monotonous feed, sudden changes in feed, a cold and damp environment, and long-distance transport can all promote the occurrence and spread of this disease. The course of this disease is generally 3 to 7 days.

Prevention and control measures

First, carry out measures such as isolation and disinfection of pig farms for externally purchased pigs and during epidemic seasons. According to the situation of affected pig farms over many years, most cases are caused by carelessness in introducing breeding stock or purchasing piglets. In addition, during epidemic seasons, failure to carry out disinfection and other measures on pig farms allows exogenous viruses to be introduced. The prevention and control of porcine transmissible gastroenteritis and epidemic diarrhea mainly relies on prevention.

Second, make good use of the combined vaccine for transmissible gastroenteritis and epidemic diarrhea in breeding pigs to enhance their resistance to the disease, starting use in September and October each year. In order to ensure the production of a high level of antibodies, administer a booster immunization once again 25-30 days after the first immunization. The Houhai acupoint of pigs is the best immunization site.

Third, if the disease occurs on a pig farm, the first step is to isolate the affected pigs and strictly disinfect the contaminated environment. Stop suckling or feeding the affected pigs, provide a cold-proof and warm environment that is clean and dry, give sufficient clean drinking water, and minimize various stresses as much as possible. Generally, symptomatic treatment is adopted, such as measures including fluid replacement, astringency, antidiarrheal treatment, and correction of acidosis, as well as methods to control secondary infection.
