The degree of dehydration is divided into three grades: mild, moderate and severe. The amount of rehydration is calculated from 30 to 100 ml/kg body weight. The dehydration nature of the disease is salt-deficient dehydration. The infusion is mainly composed of compound saline, and then appropriate input of five percent glucose or ten percent glucose solution. If the dehydration property cannot be determined, it can be supplemented by isotonic dehydration. Usually, five percent glucose physiological saline or physiological saline and five percent glucose are used.
Newborn calves have a poor resistance, viral diarrhea or diarrhea is a common disease of newborn calves, and dehydration is also caused by diarrhea. If not treated in time, the calf will dehydrate, lose weight, and even die.
Severe dehydrated calves are generally associated with metabolic acidosis. When the calf is lying and exhausted, especially if the water loss is 8% of the body weight, immediately transfer sodium bicarbonate solution, two to seven ml / kg body weight (diluted to five percent with five percent sugar) 1.5% concentration). In severe acidosis, the body is in a state of hyperkalemia. At this time, it is not appropriate to supplement potassium to avoid cardiac arrest. Slight acidosis, supplemental ion solution (saline) can improve the amount of kidney perfusion, when the kidney function is restored, the kidney can regulate the acid-base balance, no need to transfer sodium bicarbonate.
To prevent the dehydration of yak diarrhea, it is necessary to strengthen the management of beef cattle breeding and strict disinfection; the yak is fed with enough colostrum, and the disinfection during the midwifery is strict; the virus vaccine that is frequently diagnosed locally can be injected regularly. In order to prevent the epidemic of this disease, measures such as quarantine, isolation, purification, and prevention must be taken. Regular vaccinations can produce locally suitable vaccines based on local prevalence. For the cause of yak dehydration, the most common are diarrhea, diarrhea dehydration type: treatment method, multiple oral electrolyte; 5% sugar brine 500 ml + amika star 2 mm * 3 + An Nai nearly 10 ml *1 + dexamethasone 2 ml * 5, one intravenous injection.
