The objective of this study was to evaluate the relationship between hair coat shedding ability, apparent forage digestibility, and mineral status in Angus cattle. Fecal samples were collected on fall calving Angus cows for one week in March, May, and July from 2019-2022. Liver and plasma samples were collected in March and July each year. Fecal samples were analyzed for DM, ash, NDF, and ADF while liver and plasma were analyzed for mineral concentration. Data were analyzed using MIXED procedure of SAS with significance declared at P0.05. Interactions were detected for DM, NDF, ADF, and liver Fe concentration. The model included MFS, month, and MFS by month interaction for each response variable. Interpretation of results showed no clear trends or associations between hair coat shedding ability, apparent forage digestibility, and mineral status, but further investigation is needed to understand cow performance due to relationships between genes and environment.
