The pasture bonus applies to mares who are kept in the pasture. Each day they are kept in the pasture, they acquire more of a bonus, and reach the maximum pasture bonus when they have been in there for 30 days. Mares with full pasture bonus are more likely to contribute from the 'higher end' of their breeding ability.
The pasture bonus only lasts for as long as the mare is kept in the pasture. The moment you take her out, she loses it. So in order to maintain it, she must be bred in the pasture.
Stallions do not acquire pasture bonuses, you only put them in the pasture to breed.

XP is gained by breeding and creating horses. It can be lost when you sell horses back to the game, or the auction bidder (when they go through the auction with no bids). It gives you an extra stall when you earn a certain amount of XP. Losing XP doesn't have any negative affects other than it taking a bit longer to earn that extra stall. As far as I know, the amount of XP required to earn a bonus stall doesn't change regardless of how many bonus stalls you have earned. (i.e. it doesn't get harder to earn bonus stalls).

As for the pluses, it's not something I have noticed myself, so I can't shed any light on that one. Maybe someone else can?

Thank you both, that was very helpful :)

XP is not lost if you sell a horse back to the game for 1000hb. It is lost if you sell a horse any other way. (Not 100% sure about the Fantasy Gene sell back but assume you lose XP that way).

This means there is a weigh off between gaining the extra hbs for selling a horse at auction vs keeping your XP towards stalls but making fewer hbs.

I think if you sell enough of your herd, you will lose stalls.
