Symptoms, prevention and treatment of white dysentery in calves

Calf pullorum is an acute infectious disease caused by some pathogenic Escherichia coli, which mainly occurs in calves within two weeks of age, which does great harm to calves, causes death in serious cases, and affects the economic benefits of farmers. So what are the causes and symptoms of white dysentery? How to prevent and cure it? Let's take a look.

1. Etiological analysis.

The main causes of calves infected with white dysentery are congenital deficiency and acquired malaise. Congenital deficiency refers to the failure to strengthen the feeding and management of cows during pregnancy and the lack of adequate nutrition, resulting in the weakness of calves after birth. so that its resistance and immunity decline, so it is very easy to infect the disease. Acquired bad refers to the cow's less milk or poor colostrum, which contains low levels of albumin and globulin, so that calves cannot obtain enough antibodies, or because the breeding environment is poor and is in a dark and humid environment, calves catch cold, infected with disease, and possibly digestive tract disorders can cause the disease.

2. Clinical symptoms

According to its different symptoms, white dysentery can be divided into septic type, enterotoxic blood type and enteritis type.

Septicemia type: mainly occurs in 3-4-day-old calves, especially those that have not eaten colostrum, septicemia type is often acute, the incubation period is very short, calves develop diarrhea, feces are gray, mental depression, body temperature increases significantly, stop eating, will die in one day.

Enterotoxic blood type: enterotoxic blood type is mainly caused by the continuous reproduction of a large number of serotype Escherichia coli and the secretion of too much enterotoxin. the disease occurs very quickly, often without any symptoms, and the calves turn into heartache, followed by depression. Preferably coma death, accompanied by diarrhea.

Enteritis type: enteritis type has a longer course of disease than the former two, and the calf's body temperature can reach 40 degrees at the time of onset, followed by diarrhea, yellowish thin stools, with stench, and then light gray water stools mixed with blood filaments or blood clots. In the later stage of the disease, the calf's body temperature will become normal and will be accompanied by symptoms of dehydration. If left untreated, the calf will collapse to death within a day or two.

3. prevention and control measures

Prevention and treatment measures are divided into preventive measures and treatment methods, mainly prevention. During pregnancy, cows should strengthen feeding and management, feed nutritious feed to ensure that the demand can be met and make calves grow and develop normally. It is also necessary to maintain adequate nutrition for lactation after delivery. Do a good job in raising environmental hygiene, control the temperature at 15-20 degrees, lay thick bedding grass, keep the enclosure dry and clean, lest calves catch cold, and the enclosure should be disinfected regularly to inhibit the growth of bacteria. When you get sick, you can feed dysentery according to the instructions or veterinary instructions, which can have a quick effect, or intramuscular injection of oxytetracycline, neomycin or streptomycin, generally according to the ratio of 10-30mgjkg.
