Abstract
by Acetoze G.; Preisinger, K.
A recent study suggests that rumen protected capsicum (RPC) is capable of decreasing blood insulin concentrations (Oh et al., 2017). This decrease could potentially lead to repartitioning of available glucose towards the mammary gland for milk production.
The objective of this study was to evaluate early lactation performance of dairy cows fed RPC during the transition period on a commercial robotic dairy in Indiana. One hundred and five (105) Holstein dairy cows were randomly assigned to two treatments as they entered the pre-fresh pen (-21 days relative to calving): Control (no additive) and Treatment (RPC at 1 g/hd/d). All cows received the same TMR’s (pre-fresh or fresh). RPC was orally administered daily in the pre-fresh pen and provided in the robot grain, manufactured by a commercial feed mill, at the dairy through 60 DIM. The study was conducted beginning in July 2020 and ended in February 2021. Measurements included blood glucose, daily milk yield and components (fat and protein). Statistical analysis was performed using the Repeated Measures model procedure of JMP16 (SAS Institute Inc., Cary, NC).
Energy corrected milk (ECM) and milk yield were significantly (P<0.01) increased (114.5 vs 124.3 lbs/hd/d for ECM and 42.1 vs 44.7 kg/hd/d, control vs treatment, respectively) through 60 DIM for RPC cows. Milk fat (kg/hd/d) was also greater (P<0.01) for RPC cows compared to control (2.04 vs 1.86, respectively). No differences were observed for blood glucose levels (P=0.94). However there was a tendency (P=0.10) for RPC treated multiparous cows to have increased blood glucose 3 days after calving. These results indicate that transition cows supplemented with RPC may have more available glucose available for milk synthesis.
