Summary of Symposium

ABSTRACT

Breeders of meat animals have expressed their envy of the simplicity of the breeding objective for dairy cattle, i.e. milk yield. Nonetheless, you can attest that this single goal of high milk yield has not met the approval of our panel speakers or of the audience this morning.

Dr. Tyler stated that beef from dairy animals can represent an important additional source of income that has not been fully exploited. Steers and bulls of larger dairy breeds grow faster than beef steers with leaner carcasses. Eating qualities are certainly acceptable, even though marbling is somewhat less than with meat from recognized beef breeds. Present evidence does not suggest that there are strong genetic correlations between meat and milking qualities. Yet, the inclusion of beef traits in selection programs for our specialized dairy enterprises is not recommended at present. Certainly, the last chapter has not been written on this point, and further information on the heritability of growth and carcass traits and their genetic relation to milk yield is desired.
