To lamb or not to lamb, that is the question

If it’s March, it must be time to pregnancy test. We breed the best of our Rambouillet ewes to Rambouillet rams, thereby ensuring a new crop of replacement ewe lambs, as well as their brothers/cousins. Since purebred whiteface lambs are more vulnerable at birth, especially the twins, we pregnancy check the moms so that the ewes carrying twins can lamb in the sheds. The rest of the Rambouillet ewes are bred to our Hampshire rams. Their lambs have hybrid vigor and usually do fine with drop lambing on the range. Our friend Geri Parsons from Optimal Livestock Services comes up each March at mid-pregnancy to check the ewes and call out “single”, “twins”, “open” and even “triplets”. Meghan and her crew appropriately marked the ewes with a paint dab on their heads to signify their status for later sorting. Geri usually braves chill winds and long drives for several days to accomplish this task. Here’s some photos of this year’s pregnancy checking.

This is the time of year when we decide who stays and who goes.  The rams are evaluated, intimately, by Geri Parsons and her crew (this year her one-woman crew) at Optimal Livestock Services for fertility, age, potential disease or injury, and condition. The ewes are evaluated by our crew for many of the same traits which indicate whether they will be productive for another year. We check their teeth, which affects their ability to eat the hard winter grasses on the desert. We check their udders, and their overall condition. The rams are basically judged to stay or go. The ewes are judged as keepers, good old ewes who are sold to someone who can give them an easier lifestyle, and “killers” who are culled due to age, condition, and injury to their udders.

Optimal Livestock Services and the pregnant ewes

Pregnancy testing is one of the veterinary services offered by Optimal Livestock Services–Dr. Cleon Kimberling, veterinarian, and Geri Parsons, vet technician, proprietors.  We ask them to pregnancy test our ewes who are expecting white-faced lambs.  When we know which ewes are carrying twins, we can manage them separately so that they can get extra nutrition and care.  At lambing time, we can make sure they have better shelter because the white-faced lambs are more vulnerable at birth than the cross-bred lambs which have black-faced Hampshire fathers.  You old ag majors remember the lessons about “highbred vigor” which results when different types of sheep, or cows or whatever, are mixed.  The purebreds are less hardy, but they are the lambs which grow into our replacement ewes (or at least the females do).  We need both.

Geri recently showed up to check our ewes, who currently reside on the Red Desert, north of Wamsutter, Wyoming.

Dads count too–or counting on the dads–or

Dads count too–or counting on the dads–or

Most of the year, we think about the ewes–are they eating enough?  are they pregnant?  did they lamb? did they have twins?  did they elude the coyotes and bears?

Of course, in order to have those little lambs hit the ground in May and June, we need to have dads.  In the livestock world, dads (be they bucks, bulls, or stallions) count too, and we want them to be the best most productive sires we can find.  And, since it costs money and opportunity to support them for most of the year (well, actually, for all of the year, but they only work for a couple of months), we want to make sure they are the optimal sort of dad.

Who you gonna call?  Optimal Livestock Services of course!  Each fall, retired Colorado State University vet Dr. Cleon Kimberling, and his partner and sidekick Vet Tech Geri Parsons travel throughout the Rockies to test rams.  They check rams for fertility, disease, and other factors, such as age and condition, that can influence their ability to breed ewes.

Dr. Kimberling mans a traveling lab, where he examines sperm samples from rams.  Geri, with help from our crew, collects the samples in test tubes, records information about each individual, and gives all the info to Cleon, who studies and collates it.  At the end of the process, we growers are given a computer printout that rates each ram according to fertility, health, age, and other variables.

We then mark the rams who fail to make the grade.  They get a truck ride which ends in a vacation in Mexico.  I’ve never asked Dr. Kimberling what happened to his vet students who failed to make the grade.
