OK, here are some of my medical supplies. The tool box makes a great container for the smaller stuff. The goats get the Apple cider vinegar in their water every day. Iodine, vitamin C, probiotics, biohazard container for used needles, bagbalm for utters, bloodstop - be sure to read the following post and comments about why one needs bloodstop by OFG (http://adventuresinthegoodland.blogspot.com/2010/05/how-not-to-trim-hooves-and-then-what-to.html), molasses, Karo syrup, and more.
You need prescriptions to get most of these as they are reserved for registered farms and/or breeders. Make sure to keep them refrigerated. These are mostly injectables, so if you are afraid of needles they won't be of much help to you. Pictured you will find; Penicillin, Oxytocin, CD/T toxoid, epinephrine (don't give your animals shots without having this on hand), and Banamine (anti-inflammatory).
Inside the box I have a stethoscope, triple antibiotic cream, large syringes, alcohol swabs, scissors, kid colostrum, and a brown paper bag (this is for me for when I hyperventilate after using this stuff).
Finally, needles, more syringes, vet wrap (works great on broken tree branches as well), pill splitter, pill crusher, thermometer, medicine dropper, and two oral antibiotics.
Whew, If we are missing something important please let us know!
