I have this sow fattening calculator it is an excel . You will just input the date breed and it will compute the time it will farrow and days to observe for reheat. and if you input the actual date of farrowing (there are times that the sow give birth 1-3 days early or late) it will compute when you will give the specific medicine and vaccine.
Don't you have it yet?
sorry i can't remember if i have sent it to you or not.
