Abstract

The objective of this study was to compare the effects of cellulase and propylene glycol on negative energy balance (NEB) related serum indexes and urine ketone (KET) concentration of postpartum dairy cows. Twenty four early perinatal dairy cows were randomly divided into 3 groups with 8 cows per group. Three groups were control group (basal diet), propylene glycol group (basal diet+0.5% propylene glycol preparation) and cellulase group (basal diet+0.1% cellulose preparation). Serum indexes related to NEB and urine KET concentration were detected respectively on days 1, 20, 40, 60 and 100 after calving. The results showed as follows: on day 1 after calving, serum glucose and insulin concentrations of propylene glycol group were significantly higher than those of the other 2 groups (P<0.05). On days 1, 20, 40 and 60 after calving, serum non-esterified fatty acid and urine KET concentrations in propylene glycol group were significantly lower than those in control group (P<0.05), moreover, propylene glycol group was significantly lower than cellulase group on day 20 after calving (P<0.05). Serum indexes related to liver fat metabolism such as triglyceride in experimental groups were better compared to control group, and propylene glycol group showed optimum effect. Taken together, diets adding with cellulase and propylene glycol have certain improvements to NEB and the addition of 0.5% propylene glycol preparation in diet showes better effects.
