How To Use A Calf Puller.
In most cases of dystocia, the calf can be pulled by hand. There are some instances, however, when a mechanical calf puller is needed during calving. Producers should have three goals when providing calving assistance, says Matt Miesner, Kansas State University DVM: 1) A live, viable beef calf. 2) The welfare of the cow. 3) Preservation of the dam’s reproductive soundness and her ability to breed back. In most cases of dystocia during calving, the calf can be pulled by hand after correcting any abnormality of position. There are some instances, however, when a mechanical calf puller, or calf jack, is needed to pull a calf. Once it’s determined that a calf can be safely pulled, Mark Alley, DVM, a clinical assistant instructor in the North Carolina State University College of Veterinary Medicine, says a calf jack is an excellent tool when used appropriately. Most experts say you should not apply more force than that of two strong men pulling by hand. But, if you’re alone in assisting a difficult birth, a calf jack can help generate the necessary force. The criteria Alley uses for predicting ease of birth during calving is if he can get the calf’s head and front legs into the pelvis without traction and can get his hand between the calf’s forehead and the cow. “This usually means it can be a vaginal delivery,” Alley says. If the calf’s head is hitting the cow’s pelvis, it may not come through and delivery by C-section may be necessary.more
