brix refractometer colostrum

The Brix refractometer is less affected by temperature and more durable than the glass colostrometer.
Studies have reported that a value between 18% and 23% Brix is an appropriate cut point for determining good-quality colostrum (IgG >50 g/L).

What is a colostrum refractometer?

Refractometers are commonly used on farm to measure colostrum quality and work by measuring the way light bends when it passes through a solution.
We have learned that a BRIX score of 22 g/dl correlates to colostrum containing at least 50 g/L of IgG.

How do you measure colostrum quality?

Step 1 – Measurement of colostrum quality: Colostrum quality is measured by testing its specific gravity using a colostrometer or BRIX refractometer.
Good quality colostrum has a specific gravity > 1.050 (> 50 g/L of IgG antibodies) or a BRIX measurement of ≥ 22.

How do you read a Brix refractometer colostrum?

To use a Brix refractometer, a few drops of colostrum are placed on the prism and the sample cover is lowered.
The refractometer is then held up to a light source, the instrument should be held perpendicular to the light, and the Brix value is read at the line between the light and dark areas that appear on the scale._{4 jan. 2023}

Measuring colostrum quality with a Brix refractometer is a practical method to measure levels of colostral antibodies. Colostrum with a Brix value ≥ 22% should be used. Colostrum with a Brix value of < 18% should be discarded. If colostrum has a Brix value of ≥ 18% but < 22%, supplementation should be considered.
