Cervid: mule deer,whitetail,elk,goats,bighorn & stone sheep


I found a interesting article that might help us get through the cervix on our deer.* Sheep are the hardest animals in my opinion to do transcervical AI on.* I have not been able to get many threaded.* My conception rate was only 10 to 20 % on sheep so I went to LAP AI and we have been able to reach 90% conception..Here is the article aim.* Anyone who wants the whole article email me cause I can't get this on the site..* If I was doing cervical AI I would try this for sure.* This would be easy to do when we AI our deer.* I don't see what this could hurt.* I didn't check the dose for oxytocin but think I would use 100 IU on does.


The aim of this study was to evaluate the effectiveness of oxytocin in facilitation of transcervical A I technique in Barbados blackbelly sheep.


*


Thirty sheep were divided into two groups and one group was threated with 200IU of oxytocin immediately prior to artificial insemination.* The group treated with oxytocin had 100% penetration while the other group only had 20 % penetration.


The group treated with Oxytocin had a 73% conception rate which is good for sheep as anything around 50% is good.


*


Jonathan I also believe sedation does*put the semen to sleep just like it did on the doe which is why this industry needs to pack straws at 40/50 K and not this 5 to 10 K they are doing now.* I really feel semen is our problem with lack of conception because of the amount of semen per straw.* Splitting straws at low amounts of semen to start with will cause less conception.*

Heck I hit the delete button when I wanted to edit so will start all over.


I have sheep and have done cervical A.I. on them.* It is a known fact they are almost imposable to thread them.* When I used to try I would get 10 out of a hundred to thread.* I came across a article that was about sheep being bred cervical with the use of oxytocin.* They were able to thread all the sheep in the program that had been given 200IU which I thought was a lot.* They had a conception rate of 73% which is very good for sheep.* I now use LAP AI and the best we have gotten so far is 90% conception which we got last year.* I use domestic sheep LAP AI guys.


I checked the bottle of oxytocin I have here and that 200*IU dose is very high for the animal and will hurt the reproductive tract in my opinion.* I think if I did cervical A I I would try this on whitetail myself.* I would feel comfortable at a dose of 50 IU for a start to see if you would need more oxytocin to open the cervix.


If anyone wants to see the article email me and I can forward it to you.*


This might be the information we need to get through the cervix without any problems.* Oxytocin will open the cervix and make it more able to be threaded this I know for sure.*

Rick,


I would try it on some of the does.* If sheep will respond to it why wouldn't deer?

Has anyone ever found their does in estrous when they put in CIDRs?* We put in ours a couple days ago and roughly 1/3 of our does appeared to be in estrous already.* If you've had this experience do you think it positively or negatively effected AI?*

I am guessing they were sedated. What led you to believe some were cycling?
