HI!! I have a question on the longevity of frozen semen. To be more specific, I was wondering how long after its thawed its ok before you get it in the cow? Here's the reason I ask. I normally have started to AI all my girls myself, but I wanted to use a sexed semen on one of my jersey heifers. I dont have the right gun for it, but my dairy farm neighbor girl (Beth) does. She also had a straw of the bull I wanted to use, so I asked her if she would just breed my cow since she had all the stuff anyway and she has bred her herd for many years successfully. She was glad to. So this morning I noticed my jersey (Heidi) in standing heat. I called my neighbor girl and she said she'd be over this evening to AI her around 6. I wasnt exactly sure how she was going to do it, but I figured shed bring her semen tank over here and get everything ready. At about 6 I haltered Heidi and we waited. Pretty soon Beth came walking over from her farm. She already had a lubed AI glove on and the gun loaded with the semen. She had thawed and loaded the semen and everything at her place- She lives pretty much next door. We talked for a little while and then she went ahead and started AI'ing Heidi. Now I'm pretty sure this time-frame was OK for the semen, but just thought I'd ask. (I was thinking in class they said something like you have a max of 10 min once thawed maybe??) I'm guessing from the time she thawed it to when she had her arm and the gun in the cow was like 7 minutes max maybe, And 3-4 for the actual AI'ing part. I dont doubt her at all as she is very successful at her dairy and she did a great job breeding Heidi, but just curious! OH and she did have the AI gun down her shirt the whole time until she inserted it into the cow too...
Thanks so much!!
Thanks so much!!
