Question about Gestation Length
Posted: Sun Jun 16, 2013 1:08 pm
Hey everyone, Long time no see.
I have a breeding question. This is the third time we have bred my caramel northern. The first time, she had a ten day breeding window, and the babies were in born 120 - 130 days. She had 14 live births on June 18th and one stillbirth three days later.
Last year, she bred over an 18 day time frame, and the babies were born in 109 - 127 days. She had 17 live births on June 1st. Both pregnancies had very similar symptoms all the way through.
Then we come to this year where nothing has been normal, if there is such a thing in pregnancy. She bred over an 18 day time period from January 13th -February 3rd. She stopped eating May 18th. She started taking small gulps of air May 20th, although that did not become consistent until the end of May. She's actually breathing easier now than she was a week or do ago, which is very bizarre to me. On May 29th, she began exhibiting a lot of pacing, soaking in her water (which she normally does not do), and trying to figure out how to get out of her tank (which she only tries to do a day or two before birth).
She does not seem to be in distress other than the typical "I'm ready for this to be over with" type thing. She has been doing some wriggling and sitting with her head at a 45° angle the last couple of days. She will square off at her back end and develop a hump near her back legs only to have it flatten out again. She has periods of rest and then times where she walks and climbs on the sides of the walls for an hour or more. She has been repeating those behaviors for the last few days as well. She's not as big as she was last year, but then again, she carried SEVENTEEN that time.
Looking at these dates, I calculate that she is now between 133 and 151 days. I know there has been some discussion about blueys holding on to sperm until they are fertile. Could that be a possibility? Is it possible a baby could be hung up and she can't deliver? Perhaps we began breeding to early and only need to look at the end of the cycle, which would put her into more of an appropriate time frame. Am I just being a nervous mother? What behaviors should I be looking for if she is in distress or the babies are I trouble. Short of any obvious medical change, at what point do you think I should take her in and have her checked out?
Thanks. I appreciate any insight you can throw my way.
