Extract

The energy requirements of beef cows depend on their body size and milk production. Consequently, the optimum cow genotype will depend on the capability of the farming environment to produce forage if undue feeding of purchased supplements is to be avoided. In this study cows of two genotypes with differing genetic potentials for body size and milk production were each offered two levels of annual energy intake.
