Best Snack on the Trail for Goats?

[Sanhestar]

what would be the purpose of the snacks? As you mention nutritious I imagine that you want them to replenish energy.

Aside from browse along the trail - which goats find very delicious and which can sustain them very well :-) - I would rather look into snacks that are not too heavily grain based (risk of upset rumen).

Sunflower seeds come to mind, beet pulp pellets, banana chips, hazelnuts (not too many).
