BTW, on the subject of a horse taking a dump in the mounting yard. The poop would have to weigh at least 5 kgs, maybe 8 kgs (it would be wet), so this would surely have a positive effect on the animal. I read a post recently where it said that Gai Waterhouse takes the body weight of her horses seriously, and that she has two sets of scales nearby all the time. OK, so the horse takes a dump. Think about an athlete about to run 800m and is "clogged up", for want of a better phrase, compared to a similar athlete who has just had a "cleansing". The cleansed athlete would surely run better ..... So a horse who's just taken a dump would surely be improved by that event.

I'm wondering where this fits with the weights afficionados on here, or is this just one of those impoderables that we simply cannot quantify ..... except it WILL have a positive effect on the horse.
