We have Red Angus (fairly large, fairly docile, excellent quality beef) Hereford (extremely docile, very good quality beef) my neighbour has Simmental (very high headed but good mothers) Limousin (quite aggressive but excellent parents) I have one Murray Grey (extremely docile but very very large animals that eat alot, and excellent quality beef). I find the Herefords the toughest in inclement weather, the Murray Grey hates poor weather.
