The objective of this study was to evaluate the utility of a digital Brix refractometer for estimating serum immunoglobulin concentration in neonatal goats.


Blood was collected from 30 Alpine goat kids at 0-12 hours of age prior to receiving any colostrum, at 24-48 hours of age after receiving colostrum, and at 7-14 days of age. Serum was harvested and the protein measured using a digital Brix refractometer, an optical refractometer, and the Beckman colorimetric method at a commercial laboratory. Linear regression and correlation coefficient analysis was performed for all two-way results: Brix x optical, Brix x laboratory colorimetric, and optical x laboratory colorimetric.


There was significant relationship between the three serum protein analysis methods with a high degree of positive correlation between the digital Brix and optical refractometer (P < 0.0001; r = 0.87), and a moderate positive correlation between the laboratory colorimetric measurements and the digital Brix (P < 0.0001; r = 0.50) and optical refractometer (P < 0.0001; r = 0.62). Regression analysis showed a digital Brix percentage of 8.4% could be used to predict a serum protein of 5.4 g/dl and thus adequate passive transfer of maternal immunoglobulin.


The digital Brix refractometer demonstrated utility for point-of-care estimation of serum immunoglobulin to assess passive transfer status in goat kids.
