FOOD ANIMAL ECONOMICS - ECONOMIC COMPARISON OF THE PYLORO-OMENTOPEXY VS THE ROLL-AND-TOGGLE PROCEDURE FOR TREATMENT OF LEFT DISPLACEMENT OFTHE ABOMASUM IN DAIRY-CATTLE

Seventy-two lactating dairy cows with left displacement of the abomasu m were blindly assigned to treatment by use of the roll-and-toggle pro cedure or right paralumbar fossa pyoro-omentopexy. All cows were from the same large dairy herd, and survival in the herd and daily milk pro duction were measured for 120 days after treatment. The mean cost was $256.50 for roll-and-toggle cases ($50 for the procedure, $95.70 in mi lk loss and $110.80 in livestock losses). The mean cost was $406.40 fo r the pyloro-omentopexy cases ($150 for the procedure, $87.80 in milk loss, and $168.60 in livestock losses). A possible interaction with me tritis was discovered, in that pyloro-omentopexy cases cost about $100 move than roll-and-toggle cases when metritis was absent (31 cases) o r moderate (32 cases), and cost several times more when metritis was s evere (9 cases). Results of the study were in agreement with those of other studies that indicated that the closed repositioning and stabili zation techniques are generally less expensive and have comparable res ults with open repositioning and stabilization techniques. Veterinaria ns may wish to consider use of this nonsurgical technique for the rout ine correction of left displacement qi the abomasum in dairy cattle.
