Clinical and laboratory findings, treatment and outcome in 145 cows with type-2 abomasal ulcer.

摘要: This study involved 145 cows with type-2 abomasal ulcer. The most common clinical signs were, in decreasing order of frequency, depressed demeanour (100%), partial or complete anorexia (93%), rumen atony (91%), tachycardia (90%), dark black manure (80%), prolonged capillary refill time (71%), pale mucous membranes (69%) and tachypnoea (62%). abnormal laboratory findings were azotaemia (89%), low haematocrit (82%), hypokalaemia (81%), hypoproteinaemia (74%) metabolic acidosis (61%). Ten euthanased immediately after, died during, the initial examination, treatment was started (day 0) 135 cows. Treatment included blood transfusion, sodium chloride/glucose solution, calcium borogluconate, vitamin C metamizole. Fourteen also underwent right-flank laparotomy because displaced abomasum (n = 7) to rule out other causes gastrointestinal haemorrhage (n = 7). mean heart rate decreased significantly from 108 bpm on day 0 88 bpm 3. that did not receive increased transfused during this period. plasma protein concentration Ninety-one (67%) treated recovered discharged after a hospitalisation period nine days, 44 (33%) failed respond died. Aggressive treatment, which should include transfusion when indicated, is warranted valuable >50% can be expected return full production long term.
