Look at the procedure all you want, a mobile race banging and crashing about and people handling cows. Held up in the parlour and collecting yard for twice the usual amount of time.
Id challenge any man/woman to tb test our cows in the ai race, it aint gonna happen, they would just keep flicking their heads.
So maybe i am doing it all wrong, but were doing it as efficently as possible
Isn't your AI race up tight to your parlour, you need at least 4 foot of room at their heads if your going to test in race. Also if vet is fiddling with computer he/she isn't testing, need some one else to scribe.
Well laid out vet race is capable of testing more than 200/hr if staffed right, and in right place, with cows used to herringbone parlour.
