These new techniques are in addition to the existing base of ear “toward the opposite eye” approved route of administration for all cattle, as well as the “middle third of the ear,” which is approved in beef cattle and dairy heifers less than 20 months of age.

The two new techniques are a rostral direction – or toward the eye on the same side of the head – and a ventral administration, which is similar to a normal subcutaneous injection given at the base of the ear.

“Producers should work with their veterinarian to determine which base of ear injection technique for EXCEDE works best with their herd management protocols,” says Doug Hammon, senior manager of cattle technical services, Pfizer Animal Health.
 
All approved administration locations provide the same 13-day meat withdrawal time and zero milk withholding following the last dose. EXCEDE also supports the tenets of Beef Quality Assurance and is backed by the Residue Free Guarantee.
