Selective Dry Cow Therapy
Amelicor's Dry Cow Report will aid you in your decision to adopt an SDCT program
SDCT, also known as Selective Dry Cow Therapy, is a technique for drying out cows at the end of lactation.  Essentially, instead of giving an antimicrobial treatment to every cow in the herd at the end of every lactation, treatment is given based on an assessment of the individual cow.

Why Selective Dry Cow Therapy?

Blanket dry cow therapy has been the herd management standard dry off practice for dairies over the last several decades. However, with recent public health concerns about the overuse of antibiotics, dairy farms are being forced to look at alternative strategies for managing mammary infections. As a result, selectively drying out cows is becoming a popular substitute to BDCT (blanket dry cow therapy.)

SDCT Benefits:

  • Reduce the risk of antibiotic resistance- Antibiotics are important in the event of serious illnesses, if your cows are building up a resistance to antibiotics they will not help when/if your herd is exposed to other diseases or an epidemic.
  • Make better use of your records- You’ve already got the records, so why not put them to use?
  • Lowers risks of E. Coli Mastitis- Studies have shown that when antimicrobial treatments are given to cows with low cell counts there is an increased risk of E. Coli Mastitis. When selecting which cows to give antibiotics to, you can avoid giving them to these cows with low cell counts, reducing your risk for e. Coli.
  • Time Saving- Only treating a certain number of cows has obvious time saving benefits.
  • Cost Savings- Antibiotic treatment plus the teat seal is a costly drug. Most dairies that have been previously using BDCT will likely reduce their dry cow therapy by 50% when switching to SDCT.

Amelicor and Selective Dry Cow Therapy

Research has shown that drytube treatment may not be necessary on every single cow. In fact, cows have to meet three requirements to truly warrant needing the treatment:

  • (1) The cow had a case of mastitis during lactation
  • (2) The cow had/has a cell count greater than 250,000
  • (3) It’s a high producing cow, giving more than 80 pounds of milk.

If the cow meets all three criteria then it is at a significantly higher risk and should certainly be given treatment.

While this may seem simple enough on paper, there is a lot of information that is needed to make the right decisions when it comes to selectively drying off and treating cows. And that is where Amelicor steps in. DHI Plus provides you with a custom report that shows you which animals meet the criteria and need to dry off and which ones do not.

While Amelicor simplifies the selective dry cow therapy process, it is important to make your own herd management decision and check with your vet to make sure that SDCT is the right fit for your herd.
