Samples & Scans

We recently took wool samples from each of the yearling ewes, yearling rams, & some older rams. This was done right before they were sheared. The older rams have had samples taken before. However, we sampled them again to make sure their wool has not become more coarse with age.

A small patch of wool was clipped from the sheep, then placed in a plastic bag & labeled with their ear tag number. These samples were then sent to The Bill Sims Wool & Mohair Research Laboratory {Texas A&M AgriLife Research} in San Angelo.

A laser scanner determines average fiber diameter of the wool. The smaller the diameter, measured in microns (1/10,000 centimeter), the finer the fleece of wool. Finer wool means higher quality & a softer feel. This data is then used as an aide in breeding selection. Having this individual data allows us to cull individuals from the herd that have undesirable fleeces.

It is important that our sheep not only produce a quality fleece, but also a quality carcass. Ultra sounding an animal allows us to put a score of muscling by weight, which would be difficult by visual observation alone.

Casey Worrell {certified by the Ultrasound Guidelines Council} came out & ultra sounded the yearling ewes & rams that we took the samples from. He then sent us the results, including loin eye area & rib fat thickness, for each ewe & ram. With this information, we can compare each animal with a ratio of square inches of loin eye muscle per 100 pounds of animal.

Both fiber & scan data are valuable tools in selecting ‘keeper’ ewes & rams. By evaluating both pieces of data for each animal, we can make educated decisions on which ones best suit our herd.
