Developing a Calving Season Protocol for Your Cow/Calf Operation- OSU's Glenn Selk Explains How
Dr. Glenn Selk offers herd health advice as part of the weekly series known as the "Cow Calf Corner" published electronically by Dr. Peel and Dr. Glenn Selk. Today, Dr. Selk offers tips on how to go about developing a cavling protocol for your cow/calf operation.
 
"Before the spring calving season commences, now is the time to put together and post a protocol for family members and hired employees to follow when they find a cow or heifer starting in the process of 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. Older 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. Research data from Oklahoma State University and the USDA experiment station at Miles City, Montana clearly show that Stage II is much shorter, lasting approximately 60 minutes in first calf heifers, and 30 minutes in mature cows.
