Why is a milking machine responsible for informing the farmer of medical emergencies? If the machine is indeed responsible for the health of the animal, why was it still in-use without the computer?!
75 cows is a small hobby farm. I can only speak to beef cattle, it's possible that dairy cows are much more maintenance, but for beef cattle, basically no one needs any kind of tech help to keep track of the health of 75 heifers and cows.
It depends on a ton of medical history. Did the cow have a previous cesaren for example. That can make any follow up birth a cesaren or risc a tear in the womb during birth. Then there are vaccinations or the calf may be aborted late stage due to sickness.
