Springjack Pasture's last ability is a mana ability. The whole ability — including the life gain — doesn't use the stack and therefore can't be responded to.

You can sacrifice any Goats you control to activate the third ability, not just Goats created by Springjack Pasture.

If you sacrifice no Goats, you'll produce no mana and you'll gain no life.
