Delvotest SP-NT

For individual cows

If your main requirement is to test individual cows after treatment, you should use this version of Delvotest®. Delvotest® SP-NT is the broad spectrum antibiotic test most widely used on UK dairy farms, by far.  It has a fixed incubation time of 3 hours and will detect all 6 antibiotic groups which your veterinary surgeon may prescribe.  

Always check whenever:

  • Cows calve early after dry cow therapy.
  • A cow has been treated ‘Off Label’:
    when a standard dose rate has been exceeded
    when treatments are extended
    if treatments are combined
    Off- label use renders normal withdrawal periods unreliable: extend to 7 days from last
    treatment and always test before resubmitting milk for sale.
  • If treatment records are 'lost or confused'.
  • To identify which cow is responsible for a ‘mystery’ tank failure (see blue link on the right for
    protocol)

Testing all post-treatment cows, and securing a clear result before resubmitting milk for sale, 
remains the best safeguard available to ensure the integrity of your milk.

Please call us for advice if you are uncertain about which version of the test to use (01225 460234).
