[QUOTE="HOSS, post: 768836, member: 1863"] I AI'd 2 head last night for a friend. A mature cow and a heifer. As usual the cow was easy for me to do...all of 45 seconds. The heifer was another story. It took me several minutes to get the gun inserted through the cervix. Most folks say heifers are easier but that is not what I am experiencing. The cervix on most of the heifers that I have bred have been very small and tight against the pelvic floor. I have a very hard time manipulating the cervix around the gun because I cannot get a good hold on the cervix. It feels like they are attached to the pelvic floor. It finally happens but only after taking way too much time than it should. On mature cows I can hold the cervix with my hand wrapped around it and manipulate it very easy but on heifers I find that I have what feels like only the ability to shift it side to side very slightly using my index finger and thumb is a slight pinching motion. I am not sure if I am describing it well but I think those that do alot of AI will know what I am talking about. I guess my question is what techniques have you found that works best on thAT small, tightly attached cervix? Is it a practice and at what point does this become easier? I have only AI'd about 40 head since AI school and it seems that I have got the hang of cows but have to work too hard on heifers. [/QUOTE]
