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 suggests some study materials for producers to consider before calving season begins.
"Several years ago, one popular industry publication listed an Oklahoma State University Extension Bulletin as one of 6 most important pieces of equipment needed for producers during the calving season. The bulletin mentioned was Oklahoma State University
Extension Circular E-1006, '
Calving Time Management for Beef Cows and Heifers.' This circular is free to download and should be recommended reading and reviewing before each calving season. Every member of the family and hired staff that will be involved with watching cows and heifers during the calving season should read this bulletin.
“'Calving Time Management for Beef Cows and Heifers' discusses the 3 stages of a normal calving and then the causes and impacts of a difficult birth (dystocia). A thorough discussion of the signs of impending calving is followed by a description of when and how to examine a cow to determine the need for intervention. Detailed diagrams of most of the potential abnormal presentations are included with descriptions of necessary manipulations that will be required before the calf can be delivered. Proper placement of the obstetrical chains and the advantages of rotating the calf to ease passage through the pelvic opening are important sections to read.
