Examine the age of piglets to identify the cause of diarrhea

Diarrhea is one of the most common symptoms of diarrhea in piglets. Diarrhea caused by different diseases often has a certain age specificity. Understanding the age stage of diarrhea symptoms is very helpful to determine the etiology of diarrhea and scientific treatment. 1-3 days old: red dysentery occurred frequently, which was caused by Clostridium welchii type C. After a sudden, sometimes do not show clinical symptoms that is death, the main symptom is the discharge of reddish brown bloody feces, fishy smell, the mortality rate is very high. Prevention: injection of red dysentery vaccine 5~10ml on 30 days and 15 days before delivery. Prevention and treatment: because the course of the disease is too urgent, drug treatment is often ineffective, and antibiotics and sulfonamides can be used if necessary. Oral administration of penicillin 100000 units and streptomycin 500mg 2-3 times a day at birth can be used as an emergency drug prophylaxis. 2-3 days old: after infection with reproductive and respiratory syndrome, abortion, premature delivery, stillbirth, weak fetus, mummified fetus, premature delivery died immediately or a few days later, normal delivery occurred diarrhea at 2-3 days old, premature piglets were more serious, piglets with elevated body temperature, dyspnea, paste dysentery, some excreted gray or black tar-like sparse feces, a few with blood. Prevention: sows were immunized with inactivated vaccine twice a year, each time at an interval of 21 days. Attenuated vaccine was only used in piglets aged 3-18 weeks. At present, there are no effective therapeutic drugs. The feeding management of sick piglets should be strengthened, and antibiotics should be injected into piglets combined with supportive therapy to prevent secondary infection and improve the survival rate of piglets. 1-7 days old: multiple yellow dysentery, caused by pathogenic Escherichia coli. The diseased discharge is yellow, smelly, thin feces, severely diseased pig feces, dehydration, rapid emaciation, and red anus and vagina. The disease mainly occurs in piglets within a few hours after birth to 7 days old, and it is most common at the age of 1-3 days. Piglets over 7 days rarely develop the disease, and its morbidity and mortality are extremely high, up to 90%. Prevention: E. coli genetically engineered vaccine (such as K88K99987P) was injected once every 40 days and 15 days before delivery. Treatment: 2ml of dysentery and 10~20mg/ kg body weight of norfloxacin lactate were injected intramuscularly. 1-10 days old: the incidence and mortality of transmissible gastroenteritis and epidemic diarrhea were high. The epidemic characteristics and clinical symptoms of these two diseases were very similar, and most of them occurred in cold season. First sudden vomiting, followed by sharp watery diarrhea, faeces are yellowish green or gray, sometimes white, and contain milk clots, sick pigs are rapidly dehydrated, weight loss is significant, mental malaise, food intake is reduced or stopped, and the mortality rate is as high as 50% to 100%. Even if the disease is cured, the weight gain of piglets is slow, and their growth and development is hindered and even become stiff pigs. Prevention: the babies born in winter and spring were injected with 3ml 30 days before delivery with the inactivated vaccine of porcine epidemic diarrhea-transmissible gastroenteritis. Treatment: the drug treatment effect is not obvious, can use 5% glucose and sodium chloride injection 20~30ml, plus vitamin C250 mg, vitamin B6 250mg intravenous injection, twice a day, while oral norfloxacin 30mg, phenylethidine tablets 10mg. 8-15 days old: coccidia often occur, at this time the infection after the emergence of typical diarrhea symptoms, some people also call it "ten-day-old diarrhea". The main clinical symptoms are diarrhea, the color of diarrhea is from white to yellow, the shape can be from atherosclerotic to watery, but there is no bloody stool, the offspring gradually lose weight, the growth rate decreases, and the growth and development of piglets in the same litter is uneven. Prevention and treatment: piglets and adult pigs should be raised in groups, keep the enclosure clean, and isolate and treat diseased pigs in time. 25~30mg/kg, a synergistic sulfonamide preparation, can be used orally or intramuscularly for 5 to 7 days. It can also be treated with drugs such as chlorobenzene guanidine, monomycin, Madumycin and coccidia powder. 10-30 days old: multiple white dysentery caused by pathogenic Escherichia coli. Discharge gray paste thin feces, fishy smell, adhere to the anus and hindlimb, loss of appetite, dehydration and emaciation, little change in body temperature. The prevention and treatment methods can refer to the yellow dysentery of piglets. 10-60 days old: rotavirus often occurs in cold seasons, often mixed with white dysentery, only in piglets within 2 months of age, and pigs are recessive infections. The sick piglets showed mental depression, loss of appetite, frequent vomiting, rapid diarrhea, watery or paste feces, yellow-white or dark black, and the longer the diarrhea, the more obvious the dehydration. At present, there is no specific drug treatment, after the onset of breast-feeding, immediately oral or intravenous injection of 5% 10% glucose saline and 3% 10% sodium bicarbonate solution, and the use of antibiotics or sulfonamides to prevent secondary bacterial infection. 15-90 days old: multiple Strongyloides, especially at 15-30 days old, and the disease was more common in hot and humid seasons. When there are a large number of Angiostrongylus parasites in the small intestine, congestion, bleeding and ulcers occur in the small intestine, emaciation, anemia, dysentery, blood or mucus in the feces, and finally die of extreme failure. Precautions should be taken to keep the enclosure and playground dry and clean. Albendazole 20mg/kg or ivermectin 0.3~0.4mg/kg can be used for treatment. After weaning: (1) miscarriages, mummified fetuses, stillbirths and weak babies infected with atypical plague, some of them show symptoms such as depression, intermittent diarrhea and dyskinesia after birth, and often die within 2 or 3 days. The piglets grew well during the lactation period. Once weaned, the piglets showed body temperature rising to about 41 ℃, anorexia and intractable diarrhea, and feces changed from brown to yellow. In the later stage, due to anal incontinence, feces flowed down the hind legs, the stench was abnormal, the pigs lost weight rapidly, the skin of the lower abdomen and ear root showed purplish red blood stasis, the treatment was ineffective, and died in about a week. Prevention: sows are protected once before mating, boars twice a year, piglets at the age of 20-25 days and 60-70 days old are immunized twice. (2) the sows infected with pseudorabies had abortions, stillbirths, mummified fetuses, and newborn piglets died in large numbers due to lethargy, vomiting, diarrhea, etc. Pseudorabies virus caused the death of weaned piglets, mainly showing neurological symptoms, diarrhea, vomiting, etc., with an incidence of 20% and a mortality rate of 10%. At present, there is no effective treatment for this disease. Prevention: piglets were immunized with porcine pseudorabies inactivated vaccine or attenuated vaccine during weaning, once after 4 weeks, and once every half a year after 4 weeks, and once in 30 days before parturition in pregnant sows. the fattening piglets were injected once at the age of 30 to 35 days. 50-90 days old: multiple dysentery (blood dysentery), originally a spirochete of pig dysentery. The most acute type often dies within hours without any symptoms; acute cases begin to excrete yellow to gray soft feces, loss of appetite, body temperature rises to 40,40.5 ℃, followed by excretion of feces containing large amounts of mucus or blood, back arch, abdominal hanging, dehydration, increased appetite, weight loss, weakness and ataxia. Chronic symptoms are mild, manifested as repeated dysentery, from time to time discharge gray-white thin feces with mucus, and mixed with black blood, anemia, weight loss, growth and development hindered, become a stiff pig. Treatment: 0.5% dysentery net solution can be injected intramuscularly according to 0.5ml/kg body weight, or erythromycin 1~3mg/kg can be injected twice a day for 2 to 3 days. Patients with severe dysentery should also be treated with fluid replacement, cardiotonic and other symptomatic treatment. 60-120 days old: multiple paratyphoid fever, caused by salmonella infection. Clinical chronic type, body temperature is elevated or normal, periodic dysentery, feces are yellowish, yellowish brown or green, stench, mixed with blood and false membrane, some cough, skin rash and so on. Prevention: 1ml was injected intramuscularly with attenuated paratyphoid virus freeze-dried vaccine of piglets over 1 month old. Treatment: enrofloxacin is injected intramuscularly according to 5mg/kg weight, twice a day; gentamicin 1-15000 units / kg, twice a day.-- Thank you for sharing! -- very good information!
