Alsop shares some of her tips for treating cows at dry-o :  Make sure the teats are clean.  Wear gloves.  Strip quarters for any remaining milk.  Place the tube with only one-quarter of the tip in the teat to reduce damage to the teat canals.  With teat sealant, block o the top of the teat at the udder prior to inserting the tube tip. Insert the tube contents into the teat and continue to hold so they’re stuck in the teat canal for 10 seconds. We don’t want this going up into the quarter like antibiotic treatment.  Post-dip cows a er you’re done. As more data is collected on farms and more information is shared about mastitis risk, selective dry cow therapy may be an opportunity for producers to reduce antibiotic use on their farm. Selective dry cow therapy As the dairy industry aims to reduce antibiotic use on-farm, many producers have been making the shi to selective dry cow therapy. e implementation of this practice requires assessment of mastitis risk at the herd and individual cow level. “I have a few producers who have worked away from blanket treatment and it works well for them, but I’m picky on which farms start doing that,” says Alsop. “I have a list of standards before they start selective treatment.” Paibomesai says, “Working with your vet to make a plan on how to make that switch is the best way – they know what’s going on with your herd currently and can help you make those changes.” Somatic cell count (SCC) should be assessed at the herd level rst to determine if the farm is a good candidate to start selective therapy. Alsop recommends an annual average bulk tank SCC of less than 250,000 cells per millilitre, with no month where the bulk tank SCC is over 300,000 cells per millilitre. Paibomesai suggests that those who don’t meet the standards at the herd level should maintain blanket dry cow treatment and focus on reducing SCC by other means before attempting selective treatments. On a cow level, it is recommended by Alsop that SCC is less than 150,000 cells per millilitre for rst lactation animals, and less than 200,000 cells per millilitre for multiparous animals. ese benchmarks may vary between farms and should be determined in consultation with a vet. e use of teat sealant in selective dry cow therapy programs is also farm dependent. While it is recommended by Alsop to continue using teat sealants on every cow, some farms may be able to maintain udder health in a Livestock Visit your local ECHO Dealer for more information: Ancaster, Crossroads Equipment.................... 905-648-8001 Ayr, Ayr Turf & Trac ............................................ 519-632-9901 Barrie, McGill Equipment ................................. 705-503-7732 Blenheim, Southwest Small Engine Sales...... 519-676-8938 Brant County, Town & Country Sales & Service.. 519-484-2901 Brantford, Antler Services Inc ......................... 519-753-6433 Brodhagen, B&K Tire and Battery ................... 519-345-2248 Cambridge, Vincent Lawn & Garden Equip..... 519-621-7805 Castleton, Doug’s Small Engines .................... 905-349-3027 Chesley, Robert’s Farm Equipment ................. 519-363-3192 Dundas, WPE Landscape Equipment .............. 905-628-3055 Grimsby, Ag & Turf Power Service................... 905-945-4848 Hamilton, Outdoor Supplies & Equipment ...... 905-578-2411 Ingersoll, Ken’s Small Engines ....................... 519-425-4466 Meaford, Robert’s Farm Equipment................ 519-538-1660 Millbank, Zehr’s Sales & Manufacturing.......... 519-595-7579 Mississauga, WPE Landscape Equipment ..... 905-569-2055 New Dundee, Coleman Equipment ................. 519-696-2213 North Bay, Hamelin’s Outdoor Power Equipment .. 705-497-8676 Orillia, Allan Byers Equipment ......................... 705-325-2746 Owen Sound, Bobcat of Grey Bruce ............... 519-372-9100 Pembroke, AJ’s Power Products .................... 613-735-6788 Rockwood, Connect Equipment ..................... 519-856-9512 Stirling, McIntosh Motors ................................ 613-395-3757 Vars, M.R.
