Abstract

During early lactation, dairy cows undergo a phase of negative energy balance which may lead to metabolic disorders and subsequent losses in production. To help reduce this, ionophores may be administered. Administration of monensin controlled-release capsules (CRC) prior to calving improves energy balance, while choline aids in fat metabolism and transport. Choline may be a limiting nutrient in lactating dairy cows. The objective of this study was to determine whether there is an interection between these two supplements on metabolic parameters and milk production.
