I use a calander and also keep a breeding page (bred on this date will kid on that date or come back into heat on another date. I keep everything on it.
Say Mary kids May 1st, I write it down with the number of kids, then count ahead 10 days an write, worm Mary. For the kids I count ahead 6 weeks and 9 weeks and write down vaccinate Mary's kids #1, and #2. Also doing corid day 1, 2, 3, 4 and 5 starting at 3 weeks and also worm...they get checked off as they are done. The first of each month I trim feet, so alot of space is taken up with weights of kids, fecal numbers, poundage of milk if I am weighing milk on Mondays etc. And info on my bucks since my friend trims their feet once a month.
In my showbook, where all my pedigrees and super important things are kept, the only things kept forever on thier health sheets behind their pedigrees are..who they are bred to, tattoo numbers of kids, how many in the litter, and illness and true disease or other vet things, like CAE tests, stitches etc...which are copied off my calender onto their records if it is something I want to remember or may be of interest to someone if they buy her. There is less an less of this information forwarded as you realize it's meaningless
I can tell you the milker you are buying didn't have anything important happen in her kiddings, because nothing is written down
My paper in goatkeeping 101 could be a start for you, but it's so overkill with how north you live, we are all about parasites of all kinds, everything has to be about prevention to succeed. It would be just a good start and nothing more. Vicki
