Since lens with high focal distance are generally not that fast and they need high shutter to freeze moving animals, how do they get light without addind too much gain an grain ?

You don’t need what you think you need. I have a fast telephoto, but I hang around at f/6.3-f/9 and almost never shoot wide open if I don’t have to. Bright, sunny days mean I can go with a 1.4x attached and shoot at ISO 100. Cameras these days are way better at higher ISO in regards to noise than they were in the past. High ISO can easily be your friend here. Crank it up. You might be surprised.
