There are two kinds: digital and optical. The aim of this study was to evaluate the diagnostic test sensitivity and specificity of a digital refractometer (Brix refractometer) at different cut-offs in Brix% for detection of colostrum of high quality (> 50 g/L) defined by the gold standard single radial immunodiffusion (IgG g/L). There are many more applications where OPTi digital refractometers can help you measure and control, and as such Bellingham + Stanley has developed over 40 different scales to support your business. The amount of IgGs is very important in colostrum as that is the main component in colostrum that provides immunity to your calves and helps them to grow to their full potential. Blood samples must be spun in a centrifuge, or allowed to sit undisturbed for 24 hours, to separate the plasma from the whole blood before testing on the refractometer. Numerous tools are available to measure on farm colostrum quality; these include hydrometer/colostometer, digital refractometer, and optical refractometers. temperature using 2 different digital Brix refractometers (Lab A: Misco Palm Abbe PA203, MISCO Refractometer, Solon, Ohio; Labs B and C: PAL-1, Atago Co Ltd, Bellevue, Washington) with a detection range of 0% to 53%. The aims of this study were to evaluate both optical and digital Brix refractometer instruments for the measurement of Ig concentration of colostrum as compared with the gold standard radial immunodiffusion assay laboratory assessment and to determine the correlation between Ig measurements taken from fresh and frozen colostrum samples for both Brix refractometer … The Brix refractometer measures sucrose concentrations in liquids like wine and fruit juice. It is equipped with scale suitable for measuring of refractive index in degrees Brix in the range from 0 do 56 °Bx and the precision 0.1 °Bx. A commercial digital refractometer (digital hand-held pocket refractometer; Atago, Tokyo, Japan) was used with a range of 0 to 53% Brix.

The Brix scores ranged from 13.5 to 32.0% and 13.6 to 37.0% for the optical and digital Brix refractometers, respectively. It uses the Brix % scale to measure the quality of Colostrum (First Milk), which has a correlation with the immunoglobulin (IgG) value contained in Colostrum. Serum total protein was also positively correlated with %Brix (r = 1.00) and IgG (r = 0.93). Digital refractometers are more expensive, but they are more convenient and easier to use and give an exact number reading. Brix refractometry and zinc sulphate turbidity (ZST) test. A 0.3 ml of freshly drawn colostrum sample was used for the on-farm measurement of Brix percentages using a digital refractometer shortly after collection. When comparing Brix values for fresh, as well as frozen, colostrum samples between the optical and digital Brix refractometer instruments, both were found to have a strong correlation (R2= 0.96 and R2= 0.95, respectively).
