Alfalfa does not like frequent mowing (only 2-4 times a year depending on the zone) It is hardy with a heck of a root system and, nutritious for foragers and grazers.
I wouldn't use it for a yard but, for a forage and grazing area, yes, it can be good for that.
White clover is better for a mowed lawn. Mine is a mix of grasses, white clover and dandelions (those yellow flowered things are very nutritious for human and animal alike and, are easy to grow.
Okay so some might think you have a very weed filled lawn, oh well, you know it's good food for anything that will eat it.
