What’s in Ewe?

Dr. Reid Redden & Dr. Ronald Pope with Texas A&M AgriLife Extension came out in mid-January & ultra sounded 447 of our ewes. This is our third year to scan ewes for pregnancy status.

Results from this year’s scans are as follows…

Scanned Ewes

Our projected lamb crop was 136.6% for 2017 & 145.9% for 2018. Our initial projected lamb crop goal was 150%. Our projected lamb crop has increased each year since we have started scanning the ewes, & we are excited to see that this year’s projected lamb crop is over 150%!

267 of our ewes have been scanned three times now {2017, 2018, & 2019}. These ewes were carrying at least one lamb each time. 21% of those ewes have been carrying twins every scan {2,2,2}, while another 16% have been carry twins for two of the three scans {1,2,2}. It’s interesting to see trends since we now have three years of scan data on some ewes. Below is a pie chart that Dr. Redden created for those 267 ewes.

Ewes with 3 Scans

By identifying which ewes have twins, we can adjust our management in accordance with the resources we have. During lambing, we can spend more time on predator management in pastures that have ewes with twins {since they have a potentially higher lamb crop value than those with singles}. Ewes with singles don’t require as high of a nutritional level to maintain themselves & to lactate supporting one lamb.

We are gradually culling our ewes based on their pregnancy status each year. Obviously, we want to keep ewes that consistently have twins & cull the ones that consistently carry singles or any ewe that is open {not pregnant}.
