Relationship between halftime for sulfobromophthalein clearance and post-surgical prognosis in cows with abomasal

Abstract:
In 47 dairy cows with abomasal displacement, 34 (72%) cows were confirmed to have the lipid infiltration in liver by biopsy examinations. The pathological degree of the lipid infiltration was significantly higher in the cows with left abomasal displacement than in those with right one. The halftime for sulfobromophthalein clearance (BSP-T1/2) was markedly increased in nonrecovered cows with left abomasal displacement. In left abomasal displacement cases, cows with the T1/2 less than 11 min recovered regardless of the degree of liver lipid infiltration, but those with the T1/2 longer than 11 min showed a significantly lower recovery rate (44%). Therefore, it was concluded that the BSP-T1/2 was one of valuable parameters for predicting the prognosis of this disease.
