ISSUE FOCUS 30 FEED & ADDITIVE MAGAZINE March 2022 study, dry matter intake was not affected by RPC supplementation and milk yield tended to increase for RPC treatments compared to the control. Dry matter intake was not affected by RPC and feed efficiency was linearly increased by RPC supplementation. Meanwhile, no significant difference was observed on NEFA and BHB levels. RUMEN-PROTECTED CAPSICUM AND TRANSITION PERIOD PERFORMANCE In 2020-2021, a trial was performed to evaluate RPC supplementation from 21 days prior to calving through 60 days in milk under commercial conditions. Overall performance was improved for cows receiving RPC with an 8.6% increase in energy-corrected milk (See figure 2 daily milk yield). Plus, increased blood glucose at 3 days post calving points to a potential change in insulin response and liver gluconeogenesis. PROMOTING GLUCOSE SPARING AND GLUCONEOGENESIS Overall, these results could suggest that, by decreasing the amount of insulin secreted, RPC may have redirected glucose for milk production in lactating dairy cows.
