I would think there is a tremendous opportunity in South
Africa for crossing Beefmasters with commercial Bonsmara
cattle which, while developed with similar goals in mind,
are composed from different gene pool and have been
Meeting selected differently of since their creation. minds The result would be
a tremendous bang of heterosis.

In summary, cross-breeding
the
is an ideal way to inexpensively
improve production efficiency in a Beef cattle operation. And
Beefmasters are the best choice to maximize this advantage
because they bring so many excellent traits to the table.

An interesting side note, many U.S. purebred Beefmaster
breeders came into the business through BBU’s upgrading
program. They initially used a Beefmaster bull on their
commercial cows of whatever type and loved the resulting
calves, so they stayed with it. In BBU, the third cross, or 7/8
Beefmaster, can be registered as a purebred. This allowed

side using cattle they had already invested time and genetic

effort in. This helped fuel the tremendous growth of the
Beefmaster breed in the 1970’s and 80’s.
It is also important to note that the Beefmaster advantage
from cross-breeding works both ways, meaning that
you can use an outside bull on Beefmaster cows and also
yield tremendous results. I have run a large number of
E6 Beefmaster cows (certified by BBU as 50% or more
Beefmaster) and bred them to Charolais bulls I raised. The
results were fantastic! The Charolais brought the continental
look that US buyers like, but the cattle were easier keeping,
more maternal and, in general, better “ranch” cattle.

Everyone talks about the performance of
their bulls—Isa Cattle Co. has gone to great
lengths to prove it. The top herd sires in our
program have gone through the Progeny and
Carcass Test at Texas A&M. Below are the
results of over 100 calves.
