Nonesterified fatty acids during the dry-off period and their association with peripartum diseases in dairy cows

This observational study found that elevated nonesterified fatty acids (≥ 160 µmol/L) 22 to 35 days before calving are strongly associated with postpartum metabolic and infectious disorders in dairy cows. This threshold could be used by veterinarians as an early monitoring tool to identify at-risk cows and implement preventive measures before calving.

Herd-level associations between the proportion of elevated prepartum nonesterified fatty acid concentrations and postpartum diseases, reproduction, or culling on dairy farms

Dairy herds with more cows showing high blood levels of nonesterified fatty acid before calving were more likely to have cows develop reproductive diseases and to have poor success at first insemination.

Randomized controlled trial assessing the impact of a combined treatment of insulin glargine and propylene glycol on the resolution of hyperketonemia and milk production in postpartum dairy cows

Overall, the combined treatment of insulin and glycol didn’t speed up recovery of dairy cows with low blood sugar and high ketone. However, first lactation cows treated with this combination recovered faster and produced more milk compared to those given the standard treatment alone (glycol).
