At what age should a calf be weaned?

• A. Two to three months
• B. Six weeks
• C. One year
• D. Eight to ten months

Answer: (D)

Calves should be weaned when they can sustain adequate growth on solid feed without relying on milk, meaning their rumen is developed enough to process forage and starter feeds. Eight to ten months is commonly recommended because, by this age, the calf’s rumen function is mature enough to handle forage, and the animal can meet its energy and protein needs from non-milk sources. A gradual transition at this age reduces stress and digestive upset. Weaning much earlier, around two to three months or six weeks, often results in slower growth and more health or stress issues, while waiting until about a year is usually unnecessary and can complicate management and pasture use.
