In Argentina small framed animals are desired for the harsh environment in south country and they can walk very well on long distances to get water and food, as Patagonia is one of the worst places in world for enviroment. On north Argentina they wish a little bit taller animal to mate with indicus blood that are widely spread on cattle there with Brangus, Braford and Brahman base herd cows.
Here in southern Brazil we have also long distances with some farms with 2000 hectars to 6000 hectars too, divide on 300 to 400 hectars fields....maybe not so huge as in some parts of western north america, but isn't the backyard as well.
Our preference in frame, at least here in south, is based on grass fed base, so easy to make a finnished steers or cow. On north Brazil they yet think with "zebu" mind, where they like of legs. This is based on recent time operations where a good quality cattle make under a well planned crossbreeding program were not available. By the way many breeders are yet looking for leggy cattle, but the tendency is to change for a smaller animal.
