With response to that I don't know their supposed to be able to detect heat, & abnormalities in that, so it could indicate infection & it keeps a computerised track record of every cows health data - e.g how much she yields, breeds, what sort of progeny she throws, how healthy it is ect. So thats got to be good for record keeping of our overall herd health both individual & nationwide, to help with health problems & selective breeding. I know they all clean the teats ect, but I think some robots are also designed to scan & measure the teats for defects ect, I may be wrong but for 2-3 people milking 200+ animals in a shed thats even well lit, there are somethings that we may not be able to detect as early as robots but also vice versa.
Don't get me wrong I'm old fashioned too & prefer to put my notes on pen to paper, but I'm of a younger generation, & I've hand milked & my parents / grandparents - milked with both machines & by hand. I agree that there are limits that technology can be taken, & it should never be fully trusted like humans & animals alike & a good farmer will always trust their human instincts. So old methods & techniques must never be forgotten or not used, but they should coincide with the new. There is stuff that is out there that makes stuff farming easier, more traceable for things like rural crime & diseases that can be helped to prevent it. So why shouldn't I do something that would result in me knowing where I can improve on my farm work & help my income & that would have taken me twice as long to do in my grandfathers day & where we relied purely on instincts which are always good to trust but even we make mistakes.
