Interpretive Summary:

Technical Abstract: For the mature cow with low body condition scores (BCS), being too thin can accompany health issues, reduced pregnancy rates, more days to rebreeding, and lower milk production resulting in lighter calves at weaning. In addition, lower fat insulation in low BCS cows during the winter equates to additional feed requirements for warmth. The hypothesis of this study was that stress and immune factors contribute to low BCS in mature cows. The objective of this study was to determine whether there were differences in hematology parameters, hair cortisol levels, and plasma cytokine levels among animals with low body condition (BCS
