It's not Lamb milk. It's an all purpose suitable for all animals although the instructions give the same quantities for goat kids and lambs. My plan was to give 50:50 if I have enough milk. I might be able to buy goats' milk from other local goatkeepers and cut down the amount of powder.
I only went to get the bottle but thought, as the Countrywide store is miles from us, it made sense to get some milk as well.
