Which method is used to determine the age of goats?

• A. Bottom teeth
• B. Top teeth
• C. Horn rings
• D. Mutton joints in carcasses

Answer: (A)

Age estimation in goats is done by examining the teeth, especially the lower incisors. Kids have milk teeth, and permanent incisors on the lower jaw come in in a predictable sequence as they age: the first pair around one year, then the second around 1.5–2 years, the third around 2.5–3 years, and the fourth by about 3–4 years. How much those bottom teeth have worn also helps refine the estimate. Upper teeth aren’t used for aging because goats have a dental pad on the top jaw and no upper incisors. Horn rings can vary with growth and are not a reliable age indicator, and joints in carcasses don’t reveal precise age information.
