Abstract

Cows with corrected left displaced abomasum (LDA) had a longer interval to first service compared with matched controls and had lower milk yield for the first few months after calving. Subsequent to the third month after calving, LDA cows produced more milk than did their matched controls. These findings support the results of other studies in indicating that use of the roll-and-toggle procedure quickly returns cows to full milk production similar to that seen following LDA correction with more expensive surgical interventions.
