Is anyone aware of a good unbiased source that compares the strengths and weaknesses of different breeds of beef cattle? What we need is a ranking of all the major beef breeds from best to worst by trait. We are interested in traits such as maternal, growth, carcass, disposition, fertility, calving ease, etc. Anything of importance in a cow/calf operation. We need this information because we are looking for another breed to work into our Angus/Simmintal based program to maximize heterosis but are unwilling to sacrafice in other important areas. So far all the information I have found has either been too biased or too general to be of any help. Thank you.
