Study on Mechanical vs. Manual Cervical Dislocation

[BantyChooks]

I thought this paper might be of some interest to members on here, particularly as I have seen a few discussions recently on devices similar to that used in the study. The link to the full paper is free and available at the link below. Also of interest to me were the discrepancies in the time to cessation of vital signs among different age groups and the difference in reflexive behaviours between anesthetized and unanesthetized birds.

Edit: here is a good link on the proper application of manual CD.

An interesting study. I was surprised that manual CD had better outcomes. Of course technique and skill of the dispatcher have the greatest effect on outcomes overall. Perhaps a link to a YouTube video would be in order to accompany this post for anyone who visits.

A video of what?

A video of proper manual cervical dislocation. I suspect many people do it improperly causing more suffering than necessary.

YouTube seems to have taken down all the good videos, but I will get an article link and edit it in.

I'm curious as to what makes you think this? I'm not trying to argue against the idea, so I apologize if I sound that way, but I haven't seen many people other than me use it so my knowledge is limited as to how proficient most backyarders are in their technique. If you have more information I'd love to hear it.

Being a small person I find the larger birds ie. ducks, turkeys, roosters and the larger chickens are hard to use this method as my hands and arms are just not strong enough. I use a razor knife and cut the vessels for butchering but often actually cut the spinal cord in the same swipe of the knife.

*Graphic photo warning*
I processed a couple birds today via manual CD and figured this had some relevance to this thread. I believe this is an image of a dislocation between the skull and C1; I could find no jointed areas and felt only skull bone from there on out. I will be processing more next week with the broomstick method of CD and I will compare results. Perhaps I will do half manually and half with the broomstick.

I have to say I have a difficult time discerning what the photo depicts. I am interested in this method, since it is new to me.

It is a photo of a bird's head from the bottom as removed after CD was done manually. The bit in the middle is where the spinal column attached when it was alive.
