Our future efforts will be directed toward (1) improving assay sensitivity through alternate sample preparation approaches (i.e., supported-liquid extraction for plasma) and analytical platforms such as LC-MS/MS (2) a broader exploration of the factors that influence EC levels in distillers grains co-products (3) quantification of EC from beef muscle and other tissues destined for human consumption and (4) exploration of the role EC may play in development of AIP and liver disease in cattle. observations, these livestock facilities adhere to the Ag-Guide, the BQA™ Guide, and federal and state animal welfare regulations and guidelines for the handling, housing, nutrition, and health of the animals under their care.
