Micron Results for 2011

My fleece samples sat in my pickup in the box, ready to be shipped for testing most of the summer. Since the micron testing was 200.00 or so for all the samples (100+ sent in) I never seemed to have the extra cash to do it. So i finally just made it a priority. None of the results were surprising except for one. The micron testing has helped me learn a ton about each sheep's fleece and in learning the feel/texture and reasons things test at the levels that they do.

I pastured my sheep on 50% alfalfa, and the rest of the mixture was red clover, white clover, timothy, blue grass, fescue, brome and orchard grasses. I have to graze the alfalfa when it is 2/3 bloom, so it is a more stemmy than I like but the sheep have adapted well to this in the heat of the summer. spring/fall pastures are mostly fescue/blue grass and red/white clovers. Everyone is in good condition.

I'm going to list the rams first. The rams were pastured in their own system of 4 paddocks this year and I am extremely pleased with the results. Aside from the 2 polled rams below, all rams have fleeces at least 4" long already (about 9 months of fleece growth). The two polled rams have a fleece around 3". It is extremely dense and crimpy and when stretched is around 4.5". I love the variety my fleeces give me :)

For those not in the know my goals:
AFD: Average Fiber Diameter My flock goal is somewhere between 20 and 25.
SD: Standard Deviation. I want this as close to 5 or below.
CV: Coefficient of Variation. My flock goal is around 20 give or take.
CEM: Coarse Edge Mean. My goal is under 10. The lower the better. this gives it the silky handle and makes the fiber feel finer than it is sometimes. (i.e. 30 afd ewe with a CEM of 7 will feel like a low 20s AFD)
CF: Comfort Factor. This should be as close to 100% for any sheep. Adults over 80% is a goal for me (and i'm close!)
SF: Spin Fineness. What the fiber feels like as its being spun up through the hand. Your SF should always be lower than your AFD for Shetlands.

I have a page on my website (http://www.ramsay-farms.com/understandingmicrons.htm) that explains this in more detail.

I've not had a 2 year old every micron at 18 afd before!! I"m totally shocked. He has everything in his fleece that I am after and I am not disappointed with any of these numbers from any rams. I sold Roman and Caiphas who I really liked but used both of them two years. Christian is available now that I've used him for breeding and Kiso is available as I have much of his genetics in the ram and ewe flocks.

I have several ram lambs available still from these above rams as well. Please inquire! :)

Yeah!!!!! Great numbers on your rams Garrett.
I really like the short explanation of what the values mean. It will help the folks that don't micron test understand how the testing is helpful to anyone that chooses to use that tool.
I'm all about education and learning, so when I see a continued effort to educate, I applaud the time and effort involved.

I learned even more about what the numbers mean; thank-you!

SD = standard deviation.

Nice numbers!

A breed I can't stay away from

its true I guess that I would be first known for the fine wooled Shetland Sheep that I have procured and traveled across the USA and UK to ...
