Assessment of progesterone profiles and postpartum onset of luteal activity in spring calving Hereford beef suckler cattle

Acta Veterinaria Scandinavica, 2010
Background Reproduction is the single greatest factor limiting beef cattle production. Previous research on beef suckler luteal activity has largely focused on the mechanisms, and duration, of postpartum anoestrus. However, the temporal pattern of luteal
