MISCO Refractometer Q&A Forum

I am interested in purchasing a digital refractometer to test colostrum. I recently saw one of your models at a meeting but they didn’t tell us what model.

As you know colostrum quality is essential to calf health and IgG concentration is a direct indication of colostrum quality. It is no secret that the failure of passive transfer of IgG results in increased disease and death. Numerous studies point to the use of a refractometer as an excellent means of evaluating colostrum quality. The MISCO Palm Abbe PA201 digital refractometer is the best instrument to use for measuring bovine colostrum. It is generally accepted that a Brix reading of 22 or above is an indication that the colostrum quality is good.
