a few months back we took our heifer to rendezvous with a bull.
we had calculated her cycles and made sure that she'd be with the bull during our best guess at standing-heat. she stayed for over a week to be sure. we are really good at second guessing ourselves in these matters. so for the past two months we have had the question looming "is jocelyn pregnant?"
we use a method called bio-tracking to check for cattle pregnancy. this method can test for for pregnancy in goats, sheep, elk, horses, bison, and deer as well. you have to take blood from the animal but that is only mildly traumatic. they send a kit of vacutainers and some double sided needles. don't use the vacutainer part of the method described unless you are a trained vet or phlebotomist.
we used the tail vein. there are instructions that anyone can follow on their site. after a small trial we learned that a simple syringe can be used to draw the blood, instead of directly using the vacutainer and double needle. this is easier for the novice since you get more than one shot at the vein. the syringe can then transfer the blood to the vacutainer and ready for shipping. this is a real trick and should be marked if you might attempt to use bio-tracking.
after a few more days of wringing our hands the results came in last night by email on a saturday. she is pregnant. hooray we are so happy. but the numbers seemed a little high. well, really quite high. tabitha did some further reading and discovered that she is likely with twins. we are tentative about this to say the least. so back to my original question, can a person be too well informed?
what should have been a joyous sigh of relief still presents a looming question. "will she have complications delivering twins?"
