Effects of dipeptidyl peptidase IV inhibition via BI 14332 to dry matter intake (DMI) and milk yield of cows with subclinical ketosis (LSmeans ± SE).

aWith first occurrence of serum β-hydroxybutyrate (BHB) concentration ≥ 1.2 mM cows were treated with BI 14332 (HC-BI) or stayed untreated as control group (HC-Con). BI 14332 was applied once a day over a period of 7 days (intravenous, 0.3 mg/kg body weight). Subclinical ketosis was diagnosed during 1st and 2nd week of lactation (day +3, day +7 or day +10 after calving).
bThe first week (mean ± SD) was set as covariate, integrated in the MIXED procedure of SAS [24] with group and time as fixed factors (P ≤0.05; Tukey test).
