If you want to go on a fast meat run and not run out of stam on the creature use a spino they have lots of stam and gain the stam back in like 2 seconds then upgrade weight and melee on the spino and you will get lots of meat fast without running out of stam
What I’ve found is that taking a powerful creature out and just having a little fun gets more meat than you’ll ever need. I always just put the cooked meat straight into a preserving bin with spark powder and oil to make jerky, which doesn’t spoil quickly.
For getting a mass amount of meat, I recommend using either a wolf or an allo cuz they are very fast and get quite a bit of meat. Rexs and Gigas are good but force you to stop for stam many times which is so annoying 🙄
