Product Name Calf Serum Total Protein Tester
Product Image Handheld serum protein refractometer for calf management
Product Overview The Calf Serum Total Protein Tester is a portable digital refractometer designed for on-farm measurement of serum total protein in young calves. It provides a practical tool for monitoring passive transfer after colostrum feeding and supporting calf health management programs. Serum total protein measured by refractometry is closely associated with serum IgG in young calves and can be used as an indirect indicator of passive immunity. :contentReference[oaicite:0]{index=0}

Its compact handheld format is suitable for dairy farms, calf-rearing facilities, veterinary teams and livestock management operations where quick sample testing is required.
Key Features
  • Digital measurement of calf serum total protein.
  • Suitable for routine on-farm calf management.
  • Supports assessment of passive transfer following colostrum feeding.
  • Requires only a small sample for measurement.
  • Clear digital display for convenient reading.
  • Automatic temperature compensation available according to configuration.
  • Compact handheld construction for mobile farm use.
  • Durable sample surface designed for repeated testing.
  • Simple calibration and cleaning procedures.
Structural Components The tester consists of a compact polymer housing, optical measurement system, stainless-steel sample well, optical measuring surface, protective sample cover, digital LCD display, control buttons and battery compartment.

The sample area is designed for repeated contact with serum samples and can be cleaned between measurements to support hygienic testing procedures.
Working Principle / Structural Principle A prepared calf serum sample is placed on the optical measuring surface. The refractometer determines the sample's refractive properties and converts the result into a serum total protein reading. This provides a rapid indirect assessment of passive transfer status rather than a direct measurement of IgG. :contentReference[oaicite:1]{index=1}

For accurate testing, serum should be separated from whole blood before measurement. Farm testing protocols should be established with the farm veterinarian or animal health professional.

Applications
  • Commercial dairy farms and calf-rearing facilities.
  • Newborn calf passive immunity monitoring.
  • Colostrum management verification programs.
  • Veterinary and herd health management.
  • Large-scale dairy groups and integrated livestock operations.
  • Livestock equipment distribution and agricultural projects.
  • Calf ranches and professional animal husbandry operations.
Customization Options For B2B procurement, the tester can be configured according to project requirements. Available options may include measurement scales, display configuration, protective accessories, carrying cases, calibration services and private-label packaging.

OEM and distributor requirements can be discussed according to order quantity, target market and intended livestock management application.
Installation & Maintenance No permanent installation is required. The handheld tester can be used at a clean workstation in the calf-rearing or veterinary area.

Before testing, clean the sample surface and calibrate the instrument according to the operating instructions. Use separated serum rather than whole blood, place the required sample on the measurement surface, take the reading and clean the surface immediately after use. :contentReference[oaicite:3]{index=3}

Store the instrument in a clean, dry location and follow the selected model's calibration, battery replacement and maintenance recommendations.
Product FAQ

Q: What does the calf serum total protein tester measure?
A: It measures total protein concentration in separated calf blood serum and can support indirect assessment of passive immunity.

Q: Does it measure IgG directly?
A: No. Serum total protein is an indirect indicator associated with serum IgG in young calves. Laboratory immunoassay methods are required for direct IgG measurement. :contentReference[oaicite:4]{index=4}

Q: Can whole blood be tested?
A: The serum total protein test requires separated serum rather than whole blood. The sample should be prepared according to the testing protocol before measurement. :contentReference[oaicite:5]{index=5}

Q: When is serum testing commonly used?
A: Serum total protein testing is commonly incorporated into calf management programs during the early post-colostrum period to evaluate passive transfer at the herd level. :contentReference[oaicite:6]{index=6}

Q: Can the tester be customized for distributors?
A: Measurement scales, accessories, packaging and other configuration requirements can be customized according to project requirements.
