Metabolic and antioxidant status during transition is associated with changes in the granulosa cell transcriptome in the preovulatory follicle in high-producing dairy cows at the time of breeding

JOURNAL OF DAIRY SCIENCE, 105(8), 6956–6972.

By: W. Marei*, J. De Bie*, I. Xhonneux*, S. Andries*, J. Britt n & J. Leroy*
