Livestock was last for me. I had structures, fences, pasture, water sources, and plenty of things planted before the cattle came. I got the cattle last actually. The chickens and goats came before the cattle. I thought I might need goat's milk if things went sideways with a calf. If you start with livestock, and you have nothing for them to forage and no natural source of water, then you're going to be spending loads of money on feed and water.
