Mastitis Testing – Reliable Dairy Herd Health Essentials

Finding reliable mastitis testing equipment helps you identify changes in udder health quickly and make informed decisions before milk quality or herd performance is affected. Our range brings together practical mastitis test kits, CMT testing equipment and paddles for straightforward on-farm screening of individual udder quarters.

Selected for dependable everyday use in British dairy and livestock systems, these mastitis testing essentials make routine monitoring simple. Shop trusted equipment for regular herd health checks, investigating suspected subclinical mastitis and supporting effective udder management, with practical solutions suitable for the parlour, dairy or smallholding.

Choosing the Right Mastitis Testing Equipment

California Mastitis Testing (CMT) provides a quick, practical way to assess milk from individual quarters for changes associated with elevated somatic cell counts. Rather than relying solely on visible abnormalities in the milk or udder, CMT can help identify potential subclinical problems that may otherwise be difficult to spot.

When selecting your equipment, consider how frequently you test and whether you need a complete kit or replacement components:

• Choose a complete mastitis testing kit if you are starting routine screening and require both a testing paddle and suitable reagent.
• Keep sufficient CMT test liquid available for regular herd testing, particularly where somatic cell count or udder health is being monitored closely.
• Use a four-compartment paddle to keep milk from each udder quarter separate. Comparing quarters can help highlight differences that warrant further investigation.
• Support testing with good milking hygiene, including appropriate dairy wipes and teat preparation products.

For fast, controlled quarter testing, the Shoof X-Spurt Mastitis Test Paddle features an integrated 300ml reagent bottle and simultaneously dispenses equal quantities into all four sample wells, helping improve consistency during routine CMT testing.

Technical Specifications and Care

CMT works by mixing a milk sample with mastitis test reagent. The reagent reacts with somatic cells in the milk, with increased thickening or gel formation indicating a higher cell concentration and a result that may require further investigation.

Consistency is important when comparing results. Use comparable quantities of milk and reagent for each quarter and follow the instructions supplied with your chosen test. Read the reaction within the manufacturer's recommended time rather than allowing the mixture to stand for an extended period.

Always begin with clean testing equipment and avoid transferring milk between the individual paddle compartments. After testing, empty and thoroughly clean reusable equipment according to the manufacturer's instructions and allow it to dry before storage.

Good mastitis management should also form part of a wider dairy hygiene routine. Browse our animal husbandry supplies for complementary dairy, cattle health and husbandry equipment.

Pro tip: use the same testing technique every time. Keeping milk volume, reagent quantity, swirling action and reading time consistent makes quarter-to-quarter and repeat comparisons considerably more meaningful.

A CMT result is a screening aid rather than a diagnosis of the organism responsible for mastitis. Where results remain abnormal, clinical mastitis is suspected or an animal appears unwell, seek veterinary advice. Further investigation may include individual somatic cell count testing, aseptic milk sampling or bacterial culture before treatment decisions are made.

Frequently Asked Questions

What is a mastitis test used for?

Mastitis testing helps identify milk with elevated somatic cell levels that may indicate inflammation within the udder. CMT testing is particularly useful for rapid on-farm screening and identifying possible subclinical mastitis where obvious signs may be absent.

How does a California Mastitis Test work?

Milk from each udder quarter is mixed separately with CMT reagent. The reagent reacts with somatic cells, producing increasing viscosity or gel formation as cell levels rise. Comparing the four reactions helps identify quarters requiring closer investigation.

Does a positive mastitis test mean a cow needs antibiotics?

No. A CMT is a screening tool and does not identify the pathogen responsible or determine treatment. Abnormal results should be considered alongside clinical signs, history and, where appropriate, veterinary examination, somatic cell count data or milk culture.
