Abstract
During drying, the mammary gland undergoes active involution to return to a non-lactating state. Abrupt drying leads to engorgement of the mammary ducts and changes in the composition of breast secretion, triggering an involution process that involves programmed cell death and inflammation. Thus, the objective of this study is to evaluate gene expression of TNF-±, IL-1² and IL-6 in cows a…
