What is the gestation length for cattle?

• A. 300 days
• B. 260 days
• C. 283 days
• D. 290 days

Answer: (C)

Gestation length is the period from conception to calving, and for cattle the typical length is about 283 days. This value is the standard average used in veterinary and animal science texts, sitting in the middle of the usual range and reflecting common breeding outcomes. While individual pregnancies can fall a bit shorter or longer (roughly 270 to 290 days depending on factors like breed, parity, and calf sex), 283 days best represents the commonly cited average, making it the most accurate single figure among the options. The other numbers are outside the typical average: they either fall noticeably short or beyond the usual range.
