Dee Henneke, Cuero, Texas, found a useful profit tip from the pages of Drovers last year, and added another element. "As a recent ranch widow suddenly in charge of a registered ranching operation,"Ms. Henneke writes, "the color-coded vaccine syringes tip published in Drovers (April 2000) has been useful for me."

That tip, submitted by Ruby and Levi Brackett, Rogerson, Idaho, was a labeling system for syringes that used tape of different colors to match syringes with vaccine bottles. It also identified whether an injection should be given subcutaneous or intramus-cular. Ms. Henneke has added her own modification to the color-coded system.

"Here in south Texas, summertime temperatures easily reach 100 degrees F, and vaccines need to be protected from the heat and sun." Ms. Henneke used Styrofoam ice chests to create a cool, dark place to store syringes. She cut holes in the ice chests large enough to slip the syringes into between injections, using some clear packing tape to help reinforce the holes. "We color-coded the holes to hold the color-coded syringes. By going down the holes in sequence, it helps eliminate confusion about whether or not an animal has already received a specific injection."
