Piglets with yellow and white dysenteryIt refers to piglet yellow dysentery and piglet white dysentery, with high morbidity and mortality, which is one of the main diseases that affect the efficiency of the pig industry and cause the low rate of piglet rearing. Yellow and white dysentery is caused by Escherichia coli in pigs. Generally speaking, yellow dysentery usually occurs about 3-10 days after the birth of piglets, and white dysentery often occurs more than 10 days after birth, as for yellow dysentery or white dysentery, we can judge by observing the color of the feces, both are an acute infectious disease caused by pathogenic Escherichia coli newborn piglets, once it occurs, grasp the **, it is necessary to control the disease in a short period of time, so as not to cause greater losses.
Piglets with dysenterySick pigs mainly have diarrhea, the feces are white, gray-white, light yellow-green or gray-brown, porridge-like, fishy-smelling, sometimes mixed with bubbles in the feces. The body temperature of the sick pig is not high, the spirit is still good, and there is an appetite.
Piglet of yellow dysenteryThe main symptom is diarrhea, the feces are mostly yellow and watery, containing small pieces of curd, flowing down the **, and there are no fecal traces around it, which is easy to be ignored. When caught, the piglets struggled and chirped, and fecal water emerged from the **.
Management measures
According to many years of experience in the diagnosis and treatment of grassroots level, the following comprehensive prevention and control measures for piglet yellow and white dysentery are for reference only. 1. Improper sanitation and feeding management of pig farms is the main cause of this disease, and it is necessary to strengthen the breeding management and environmental disinfection of breeding pigs to prevent it. In summer, ensure that the enclosure is ventilated to prevent heat stroke and cool, and reduce the heat stress of pigsIn winter, it is necessary to pay attention to keeping warm and warm, changing the bedding frequently, and preventing stress factors such as cool breeze from causing piglets to catch colds, thereby inducing yellow diarrhea in piglets. Disinfect at all times.
2. Strengthen the management of sow feeding, and the feeding of sows during pregnancy should be nutritious and comprehensive, and mildew feed should not be fed. In order to prevent the sow from having too high milk concentration, it is necessary to pay attention to reducing the concentrate feeding by about 15% 7 days before giving birth to avoid indigestion of piglets. In addition, the pens should be disinfected 5 days before farrowing, and the sow's udders and ** should be cleaned to remove bacteria and dirt from the nipple holes to minimize the infection caused by piglets**.
3. Strengthen the management of piglet feeding, and the key measures to prevent the occurrence of yellow diarrhea in piglets are to first do a good job in the insulation measures of piglets, and adjust the corresponding temperature according to different ages. Newborn piglets must be fed colostrum so that they can obtain maternal antibodies;It can be properly fed for about a week to exercise its gastrointestinal function.
Vaccine prophylaxis
1. If conditions permit, pregnant sows should be injected intramuscularly with Escherichia coli trivalent inactivated vaccine in piglets 40 days and 15 days before giving birth, 2ml each time.
Long-acting oxytetracycline 05 ml, castration followed by injection 05 ml cephalosporin.
Measures
1. Once you find that you are sick, isolate immediately**. 15 mg enrofloxacin, 5 10 mg kg of eplofloxacin per kilogram of body weight, 2 times a day, 3 to 5 days.
2. Probiotic products beneficial to intestinal function are fed with microecological preparations before piglets, which have good results.
3. During the course of the disease, electrolytic multivitamin and haloperic acid should be added to the drinking water, and glucose normal saline can also be fed, and electrolytes should be supplemented at the same time to prevent dehydration.
