Grass-efficient cattle: judge performance on the pasture you have

Grass efficiency is a practical description, not a single standardized breed label. For a grazing cow herd, useful questions include whether cows maintain suitable body condition, rebreed and wean calves on the available pasture. For finishing cattle, growth rate and time to finish matter too. These are different production goals.

Pasture quality changes with species, maturity, rainfall and season. Record grazing days, stocking rate, supplements and body condition when comparing cattle. An animal receiving substantial supplementation cannot fairly be compared with one relying on pasture alone without accounting for that difference.

Ask for results from a grazing environment similar to yours, including difficult seasons. Select cattle and manage stocking pressure together: genetics cannot make inadequate forage supply meet an animal's requirements. Use forage tests and local extension advice to plan nutritional gaps rather than withholding needed feed to prove an animal is grass adapted.
