When do we intervene and assist a cow or heifer in labor?
Dr. Glenn Selk, Extension Cattle Specialist, Oklahoma State University
Fall calving season is upon the Oklahoma ranches that have fall and winter calving. An issue facing the rancher at calving time, is the amount of time heifers or cows are allowed to be in labor before assistance is given. Traditional text books, fact sheets and magazine articles stated that “Stage II” of labor lasted from 2 to 4 hours. “Stage II” is defined as that portion of the birthing process from the first appearance of the water bag until the baby calf is delivered.
