A newborn foal is entirely dependent on maternal antibodies, absorbed following ingestion of colostrum, from its dam in the first few hours of life for immune protection.
Failure of the passive transfer of maternal antibodies puts the foal at significant risk of infectious diseases. Monitoring the success of passive transfer by measuring levels of IgG in the blood of neonatal foals is critical if early intervention and treatment is required.
The 591a Densimeter, when loaded with the foal IgG calibration, provides a quick and accurate onsite measurement of the foal's immunoglobulin G (IgG) level.
This test utilizes a small sample of the foal's blood to determine the concentration of IgG present at the time of the test.
The 591a Densimeter display shows step-by-step prompts which guide the operator through
the IgG test. Automatic temperature stabilization of the test compartment insures maximum accuracy in low temperature environments. The entire IgG test takes approximately 15 minutes and provides an accurate numeric result
(mg/dl). There are no color change charts or need to estimate degree of agglutination with this test.
The Foal IgG Analyzer Kit includes the 591a Densimeter, foal IgG concentration calibration, and all
equipment and supplies needed for the first 20 tests. Each kit includes pre-filled measurement and dilution cuvettes which minimize onsite setup time and help insure accurate results. Additional Foal IgG Test Supply Kits are sold with all supplies needed for ten (10) tests.
ARS recommends that this test and treatment of foals with inadequate passive transfer be done under the
direction of their veterinarian. An IgG upgrade kit is available to add the IgG capability to your 591a Sperm Counter.
