The serum total protein refractometer measures the refractive index and predicts the serum total protein content of the sample. The prediction is based on the statistical relationship between total protein and refractive index.
At the time of sample analysis serum was thawed in a 20 °C water bath. The digital Brix refractometer was calibrated before each sample analysis in a similar manner to colostrum analysis, and then the serum Brix % recorded. Total serum protein was measured using a clinical refractometer. Serum total protein (STP) concentrations (%Brix) were measured using a digital Brix refractometer (PAL-1, Atago, Japan) placing a quantity of 0.3 mL on the prism surface. The instrument has a measurement range from 0 to 53%, a high accuracy of ±0.1% and is independent of ambient temperature (0–99 °C).The serum total protein refractometer measures the refractive index and predicts the serum total protein content . Predicting serum IgG, whether using a total protein refractometer, BRIX refractometer or other method, is always an on farm estimate. Therefore, the method is best used for multiple animals and to determine if .

Blood serum total protein and colostrum total solids content were determined using a Brix refractometer. Chemical analysis of colostrum was performed with Milkoscan. Univariate mixed linear models were used to estimate the heritability of calfSTP and cowSTP and their genetic and phenotypic correlations with colostrum traits.
A practical method to monitor passive immunity in newborn calves is to use the refractometer to measure a sample of serum for total protein. Early in life serum total protein (STP) is highly correlated with serum IgG, and STP is easy to measure with a refractometer. For more information on how refractometers work and the relationship between . Ewes’ colostrum and lamb blood serum samples were collected at 6, 12, 24 and 48 h postpartum to measure the total serum protein by digital Brix refractometer. The confirmation of lambs immunological status was performed by the zinc sulphate turbidity (ZST) test on blood samples collected from lambs 12 and 24 h postpartum. . Ewes’ colostrum and lamb blood serum samples were collected at 6, 12, 24 and 48 h postpartum to measure the total serum protein by digital Brix refractometer. The confirmation of lambs .
The objective of this study was to evaluate the utility of a digital Brix refractometer for the assessment of success of passive transfer of maternal immunoglobulin compared with the measurement of serum total protein (STP) by refractometry. Blood samples (n = 400) were collected from calves at 3 to 6d of age. By definition, FPT has occurred when total serum protein is below 5.2 – 5.5 g/dL or total serum IgG is below 10 mg/mL. A recent Washington State University College of Vet Medicine study evaluated use of the Brix Refractometer to determine FPT and correlated the Brix percentage reading with serum IgG levels. From the study, they determined . The Brix scale has been adapted for the dairy industry to measure the quality of colostrum, percent solids of milk, and blood total protein of newborn calves. Figure 3 shows what a Brix reading looks like on a manual refractometer, reading .

At the time of sample analysis serum was thawed in a 20 °C water bath. The digital Brix refractometer was calibrated before each sample analysis in a similar manner to colostrum analysis, and then the serum Brix % recorded. Total serum protein was measured using a clinical refractometer.
Fisherbrand™ Handheld Digital Brix Refractometers are portable, reliable and accurate. Whether you are checking sugar or sucrose concentrations you can rest assured you are getting an accurate reading. . With the ability to read Serum Protein, Specific Gravity and Refractive Index all on a single scale, it makes it the ideal choice. Pricing .
Semantic Scholar extracted view of "Use of digital Brix refractometer to estimate total protein levels in Santa Inês ewes’ colostrum and lambs’ blood serum" by M. R. Santiago et al. . data suggest that digital refractometry is an acceptable and rapid method to estimate immunoglobulin G in Jersey calf serum and validate the use of .

Comparison of refractometers and test endpoints in the measurement of serum protein concentration to assess passive transfer status in calves. J Am Vet Med Assoc 2002 .The aim of this study was to determine the diagnostic accuracy of digital serum total protein (TP) and digital Brix refractometers in estimating different passive immunity levels (<10, <18, <25 mg/mL) in dairy calves. Blood samples were collected from 260 . Measurement of serum total protein concentration using digital and optical refractometry, serum GCT, and colostrum BRIX refractometer are considered fast, inexpensive and accurate methods for the diagnosis of FTPI .The DD-3 Digital-Dairy Refractometer will provide reliable estimates of colostrum quality (Brix method), blood serum protein concentration, percent solids in waste milk, and calf hydration.

The Brix scale refractometers cover a wide range of applications from cutting fluids (0-10% brix and 0-32% brix) to fruit juice and honey. . The clinical units measure serum protein (SP), SG (specific gravity) and RI (refractive index). Optical and digital models are available. We also supply specialist gem refractometers. Blood serum total protein and colostrum total solids content were determined using a Brix refractometer. Chemical analysis of colostrum was performed with Milkoscan. Univariate mixed linear models were used to estimate the heritability of calfSTP and cowSTP and their genetic and phenotypic correlations with colostrum traits.
Additionally, agreements between Brix refractometry and optical refractometer (serum total protein, STP) and between Brix refractometry and ELISA (immunoglobulin G, IgG) were also investigated. Forty-five sows and 269 piglets from three different farms were enrolled in .OPTIKA offers a wide range of hand refractometers to ensure incredibly rapid and convenient measurement of concentration in liquid and semi-solid samples, combining accurate performance with excellent repeatability.They give a direct reading of different scales: Brix, Oechsle, Babo, serum protein, refractive index and concentration of freezing liquids or alcohol.compared with the measurement of serum total protein (STP) by refractometry.

Data are presented as mean values ± standard deviation (SD). Colostrum and serum Brix refractometer measurements expressed in %Brix units or g/dL were plotted against ELISA results (mg/mL). From these distribution . A significant increase of serum Brix, serum total protein, and IgG were found between T0 and T3 (p < 0.001), as summarized in . The objectives of this study were determining the accuracy of digital serum total protein refractometer (STP-REF) and digital Brix refractometer (BRIX-REF) in the estimating of different passive .MISCO Digital-Dairy Refractometer measures Colostrum Quality, IgG Blood Level, Waste Milk, Milk Replacer, and Calf Hydration on Dairy Farms. . Digital Dairy Refractometer – Colostrum – Serum Total Protein – Milk Solids – Hydration – MISCO DD-3 Refractometer $ 595.00. Quick View. Dairy Calf Management . Note: scale #003 (BRIX) is .The blood serum total protein test requires a sample of blood serum, not whole blood. Samples must be spun in a centrifuge, or allowed to sit undisturbed for 24 hours, to separate the serum from the whole blood before testing on the refractometer. The versatile Brix scale can be used to measure the cut-off point separating good colostrum from bad.
