Testing dairy goats may seem overwhelming at first, but understanding what to test for and when to do it will help you establish an effective health management program. Whether you’re a small homestead farmer or running a commercial dairy operation, knowing the right testing protocols can make the difference between a thriving herd and costly health issues down the road.
Understanding the Importance of Dairy Goat Health Testing
Regular health testing for dairy goats offers three critical benefits:
Hey hey, be sure to sign up & receive fun & interesting updates…
- Disease Prevention: Early detection helps stop the spread of contagious diseases like CAE Johne’s Disease before they affect your entire herd.
- Milk Safety: Testing ensures your goats produce safe milk that meets health regulations and standards for both personal consumption and commercial sale.
- Herd Management: Health screenings help maintain breeding programs maximize milk production and protect your investment in quality dairy goats.
Testing isn’t just about meeting requirements – it’s about protecting your herd’s future and maintaining a profitable dairy operation. Key tests assess blood antibodies milk quality and reproductive health ensuring your goats stay productive and healthy.
Testing for Common Bacterial Diseases in Dairy Goats
Regular bacterial disease testing helps maintain herd health and ensures compliance with state regulations.
Brucellosis Testing Requirements
You’ll need annual brucellosis testing for your dairy goats through a blood test conducted by a licensed veterinarian. This zoonotic disease can affect both goats and humans making testing mandatory in most states. The test requires drawing blood samples from goats over 6 months old and submitting them to approved laboratories for analysis.
Tuberculosis Screening Protocols
Your dairy goats should undergo tuberculosis testing every 12-24 months using the intradermal skin test method. A veterinarian injects a small amount of tuberculin into the goat’s skin and checks for reactions after 72 hours. Positive reactors require immediate isolation and follow-up testing to confirm diagnosis.
Johne’s Disease Monitoring
Test your herd for Johne’s Disease annually using either blood or fecal samples. This bacterial infection affects the intestinal tract and can remain dormant for years before showing symptoms. Early detection through ELISA blood testing or PCR fecal testing helps prevent the spread within your herd and enables targeted management strategies.
Essential Viral Disease Testing for Dairy Goats
Regular viral disease testing helps protect your dairy goat herd from devastating infections that can impact milk production and herd health.
Caprine Arthritis Encephalitis (CAE) Testing
Test your goats annually for CAE using an ELISA blood test that detects antibodies. This incurable virus affects joints lymph nodes & mammary tissue making detection crucial for herd management. Separate positive animals immediately & implement strict prevention protocols to protect uninfected goats.
Small Ruminant Lentivirus (SRLV) Screening
SRLV testing identifies both CAE & Maedi-visna viruses through PCR blood analysis. Schedule testing every 6-12 months especially before breeding season or acquiring new animals. Early detection prevents transmission through colostrum milk & direct contact between goats.
Parasitic Disease Testing and Prevention
Regular parasite testing and prevention are crucial for maintaining healthy dairy goats and optimal milk production. Implementing a comprehensive parasite control program helps protect your herd from both internal and external threats.
Internal Parasite Testing Methods
Monitor your goats’ parasite loads through regular fecal egg counts (FEC) every 4-6 weeks. Use the FAMACHA scoring system to check for anemia caused by barber pole worms. Collect fresh fecal samples in the morning and submit them to your veterinarian for microscopic examination to identify specific parasites like coccidia strongyles and tapeworms.
External Parasite Monitoring
Check your goats weekly for signs of external parasites such as lice mites and ticks. Part the hair in multiple locations especially around the neck shoulders and tail base to spot infestations. Record any unusual scratching hair loss or skin irritation and treat affected animals promptly with appropriate medications approved for dairy goats.
Routine Blood Testing and Health Screenings
Regular blood testing provides vital insights into your dairy goats’ overall health status and helps detect potential issues before they become serious problems.
Complete Blood Count Analysis
Complete Blood Count (CBC) tests to measure key blood components including red cells white cells platelets and hemoglobin levels. Schedule CBC tests annually or when goats show signs of illness. This screening helps detect anemia infection inflammation and other health issues that can impact milk production.
Mineral and Nutrient Level Testing
Test your dairy goats’ blood twice yearly for essential minerals like selenium copper zinc and vitamin E. Track calcium and phosphorus levels during pregnancy and lactation to prevent metabolic disorders. Adjust feed supplements based on test results to maintain optimal nutrient balance for milk production.
Pregnancy and Reproductive Health Testing
Regular reproductive health monitoring ensures optimal breeding success and maintains your dairy goat herd’s productivity.
Pregnancy Testing Methods
Test your does for pregnancy using blood tests 30 days post-breeding or ultrasound after 45 days. Blood tests detect pregnancy-specific protein B (PSPB) with 98% accuracy while ultrasounds provide visual confirmation of kids and potential multiples. For experienced farmers visual observation of physical changes and return-to-heat patterns can supplement testing.
Reproductive Disease Screening
Screen your does annually for chlamydia toxoplasmosis and Q fever through blood tests. Test for brucellosis before each breeding season as it causes abortions and infertility. Monitor for signs of listeriosis which can trigger late-term pregnancy losses. Early detection prevents reproductive failures and protects your breeding program.

Milk Quality and Safety Testing
Regular milk testing ensures dairy goat milk meets safety standards and maintains optimal quality for consumption or processing.
Somatic Cell Count Testing
Monitor your goats’ udder health by testing somatic cell counts every 30-45 days. High counts (over 1,000,000 cells/mL) indicate mastitis infection requiring immediate treatment. Use California Mastitis Test (CMT) paddles for quick on-farm screening between laboratory tests to catch problems early.
Bacteria and Antibiotic Residue Screening
Test milk samples monthly for bacterial contamination including E. coli Staphylococcus aureus and Streptococcus species. Screen for antibiotic residues before releasing treated goats’ milk into your supply using rapid test kits. State regulations require bacterial counts below 100,000 CFU/mL for raw milk sales.
| Test Type | Frequency | Acceptable Range |
|---|---|---|
| Somatic Cell Count | 30-45 days | <1,000,000 cells/mL |
| Bacterial Count | Monthly | <100,000 CFU/mL |
| Antibiotic Residue | After treatment | Non-detectable |
Annual Testing Schedule and Record Keeping
Create a year-round testing calendar to track essential health screenings for your dairy goats:
- January-February: Schedule CAE ELISA blood tests and pregnancy checks for spring kidding
- March-April: Conduct fecal egg counts and FAMACHA scoring as parasites become active
- May-June: Complete TB testing and milk quality analysis for peak production season
- July-August: Perform CL screening and mineral level assessments
- September-October: Run Johne’s Disease tests and breeding soundness evaluations
- November-December: Schedule brucellosis testing and annual wellness checks
