Welcome to Yocom-McColl on the Web!

We have been in business since 1964 as an independently owned, commercial wool testing lab located in Denver, Colorado. We test raw wool for yield and fiber diameter and also test at various stages of the textile manufacturing process.

We also provide individual animal testing to provide selection data for breeders. We provide individual micron test reporting which is fast, accurate and affordable for sheep, alpacas, angora goats, cashmere goats and llamas.

Individual animal fiber test pricing information can be found in the following sample forms linked below. If you need a more complete list of wool testing services, please email us. Microprojection continues to be available as a manual method for measuring fiber diameter for core testing in addition to image analysis by Laserscan and OFDA100 instruments.

Yocom-McColl is equipped with state-of-the-art instrumentation technology for measuring average fiber diameter of animal fibers, CSIRO's Sirolan Laserscan and BSC Electronics' OFDA100(Optical Fibre Diameter Analyser) and for staple profile measurement, the OFDA2000.

Alpaca Owners Association Inc (EPD Program)

EPDs provide an estimate of the average difference in an individual's progeny performance as compared to the national alpaca herd OR as compared to another individual alpaca. EPDs cannot predict the outcome of a single breeding, but rather predict the progeny performance on average over a number of progeny. Utilization of EPDs for traits in breeding plans which include selection for desired traits will, over time, move the herd's performance in the desired direction.
