Feeder (below right)
CFTEP Activities in FY 2010
• New equipment--- deer feeding, vehicles, computers,
tractors, portable dip vats, spray boxes, etc.
• New staff--- targeted to areas of need– deer feeding,
epidemiologists, MPI’s in Starr County, IT support
• New management --- borrowed from other successful
programs--- written Herd plans, emphasis on
epidemiology, mapping, RFID / MIMS in each
quarantined herd
• More interaction/consultation with wildlife biologists
Treated Corn Delivery to Deer
•USDA begins bulk feeding
of Ivomec-treated corn
•Bulk mixing equipment
purchased
•Large trucks to deliver
•More personnel assigned
to affected counties
CFTEP Activities (continued)
• Database development
• custom software or utilize TAHC mgt. software
• deer feeding program 1st
• Infested pasture management 2nd (CFTEP info
management is identical to 1943)
• Increased accountability program results
• Increased ability for public to analyze success
• Quarterly management reviews
• Monthly Information dissemination
Future Tools
• Vaccines?
• Gavac under ARS evaluation in Texas – field trial in 2011
• Australian
• Autogenous?
• Ivermectin Treated Molasses Tubs
• MUMS approval process by FDA underway by Postive Feed -TX
• Advantage
• self-treat cattle on infested or adjacent pastures
• minimize the expense of gathering the cattle
• Field trial in 2011 – final approval time uncertain
