Wow, thought it would’ve been a little more complicated then that. I can’t help but imagine what the recruiting and hiring process is like for that job. I assume they use a pretty vague description when they post an ad for the job, but at some point during the interview they've gotta explain the job responsibilities and duties of a professional piss catcher.
Have to believe that since estrus in deer is based on photo period, does in stalls with light manipulation and catheters to cleanly capture the urine. That is how they do it with horses used to produce birth control hormones.
Clean stalls with a stainless steel drop pan sytem, access to plenty of water . Just pull the pan periodically. or having it strain and drop into a collection vessel. The thing about estrus urine is the scent is developed in the vaginal area through mucus. The does bladder hangs under the vaginal area and exits through the vaginal area picking up that hormone loaded mucus.
saw a video many years ago, deer were lined up in stalls I a barn, cement floor, all droppings and pee flowed downhill into a trough collecting all, then debris was filtered from the liquid, WALLA ! You had pee
I kind of prefer the guy with a 7-11 cup collection system. I bet he gets a hoof to the face on a pretty regular basis.
