Prevention and treatment of dyspepsia in calves with diarrhea, weakness, drowsiness and coma

Digestive dysfunction in calves is collectively referred to as dyspepsia. Dyspepsia is one of the common gastrointestinal diseases in lactating calves, which is characterized by diarrhea. The disease does great harm to the growth and development of calves. In order to be cured in time, it is necessary to find out the cause of the disease and take comprehensive prevention and control measures to be effective.

Calf

1. Etiology:

1. Improper feeding and management of cows and calves: most of them get sick shortly after sucking breast milk or after 1-2 days. Calves can not eat colostrum or lack of colostrum, which leads to the lack of immunoglobulins that form antibodies in the body, resulting in low disease resistance of calves. If the nipple or breast feeder is not sold, the artificial milk is insufficient, the milk temperature is too high and too low, and the transition from lactation to feeding is not good, all can cause the disease.

2. The incomplete nutrition of pregnant cows, especially the deficiency of protein, vitamins and minerals, can disorder the nutritional metabolism of cows, affect the normal development of fetus, and the calves have dysplasia, weak physique and low resistance. For example, lack of VA in breast milk can cause keratosis of digestive tract mucosa of calves; deficiency of VB can cause disturbance of gastrointestinal peristaltic motility; when lack of VC, it can weaken the secretory function of calf stomach.

3. Bad environment: such as too low temperature, damp enclosure, lack of sunshine, stuffy and crowded, poor ventilation and so on.

Second, clinical symptoms:

The disease is characterized by diarrhea, the initial calves, the spirit is still good, with the aggravation of the disease, there are corresponding symptoms. Diarrhea stool is porridge-like, watery, yellow or dark green, intestinal sound high and bright, with symptoms of dysphoria and abdominal pain. When dehydrated, the heart beats faster, the skin is inelastic, the eyeballs are sunken, weak, and stand unsteadily. When the intestinal contents ferment spoilage, toxin absorption, the emergence of self-poisoning, there can be neurological symptoms, such as excitement, spasm, severe drowsiness, coma.

3. Prevention:

To strengthen the feeding and management of cows during pregnancy, especially in the later stage of pregnancy, adequate nutrition should be given to ensure the supply of protein, vitamins and minerals; improve sanitary conditions and feeding and nursing measures; after calves are born, colostrum should be eaten as soon as possible. The enclosure should not only protect against cold and warmth, but also be ventilated and transparent. Regular cleaning and disinfection, replacement of bedding grass, etc.

4. Treatment:

1. Starvation therapy: the milk was banned for 8 hours for 10 hours, during which oral rehydration salts were given, that is, 3.5 g sodium chloride, 1.5 g potassium chloride, 2.5 g sodium bicarbonate, 20 g glucose, add water to 11, and replenish them according to the 50~100ml/kg standard.

2. Excluding gastrointestinal contents: using laxative or warm water enema to remove gastrointestinal contents of calves to promote digestion, can supplement pepsin and appropriate amount of VB, VC.

3. Taking antibiotics: in order to prevent calf intestinal infection, you can take kanamycin 0.005~0.01g/kg body weight. In order to prevent intestinal spoilage and fermentation, antiseptic yeast drugs such as keliolin, fish stone fat and potassium permanganate can also be used appropriately.
