Who is Going to Lamb and When? Ultrasounds

For the last few years I’ve asked the UC Davis vets to come here and do ultrasounds. It is certainly useful to know ahead of time the ewes that are not pregnant and, hopefully, the number of lambs to expect from those that are.

I told the Dr. Smith the dates the ewes were with rams and December 20 was chosen as the optimal time for ultrasounds. (Never mind that a few ewes went in with the new ram, Eli, right at Thanksgiving. This ultrasound date was scheduled before Eli came here. It won’t be hard when the time comes to know if those few ewes will lamb.

I purposely did not breed as many ewes this year because of the limited space with our pasture being off limits for most, if not all, of the next grazing season. If you read this blog regularly then you know about the Pasture and Irrigation Renovation going on. Look back over the last few months for those blog posts.

Farm Club members came and, since I was otherwise preoccupied with an overlapping visit by my son and DIL and Matt’s offer to help me with some loom/computer issues, they did all the work of getting the sheep organized and in pens, ready for the vets.

There were four from UC Davis. I lose track of the titles, but I think one person was an intern and/or student and maybe a couple were in residency. They took turns doing the scans and reading the results, with Dr. Smith overseeing it all.

Don’t ask me what we’re seeing. I’m good when I see a ribcage go by as they move the probe around, but I have a hard time with the rest of it unless it’s pointed out. They judge size of the lamb’s head and, therefore, its gestational age. Amount of fluid and relative position of the lambs are other factors they consider.

Trading places in scanning.

Meanwhile, one reason Matt came was to climb the weeping willow and cut a couple of large branches that had broken during the summer. FIY, he is using safety gear to prevent falling in case of slips.

It’s amazing how quickly this tree has grown. Matt cut the problem branches, but then cleaned out a lot more where it overhangs the pasture and the fence.

Back at the barn they are still scanning, but we could used last year’s lambing list on the white board (to be erased at the beginning of the next lambing) to pick out which ewes had triplets last year.

Here are the stats:
Fetuses counted: 51
Sets of triplets: 2
Sets of twins: 17
Singles: 5
Sets of 2+ (twins, but not ruling out a 3rd): 3
Ewes pregnant: 27
Ewes open who were with a ram: 3
Ewes maybe pregnant, bred late by Eli: 4
Ewes not with.a ram: 7
Ewe lambs not bred: 8

Stay tuned for March 9, the first due date based on when I put rams in with ewes.
