Abstract

Forty-four holstein dairy cows were randomly enrolled in the treatment group (group 1, n=19) or control group (group 2, n=25) at calving. Group 1 received prophylactic propylene glycol treatment (PPGT) (300 ml/cow, beginning at calving, total 3 days). The group 2 remained untreated. All animals were tested on blood and milk beta-hydroxybutyric acid (BHBA) at postpartum week 2 and 4 (PW2 and 4), body condition scores (BCS), average daily milk production (ADMP) and postpartum health disorders were monitored in 90 days in milk (90 DIM). The incidence of subclinical ketosis (SCK) was 8% and 4% in blood test (BHBA≥1.2 mmol/L) and by 12% and 24% in milk test (BHBA≥200 µmol/L) in group 2 at PW2 and PW4 respectively. SCK was not detected in group 1. The study cows lost BCS on postpartum days 30 and 60. ADMP was significantly different (P
