In ancient times, such as during the period of Ancient Greece and Ancient Rome, full-grown cows were significantly smaller than modern cattle. Based on archaeological evidence (bones and remains), historians and archaeozoologists estimate the following sizes: • Height: Approximately 100–120 cm (3.3–4 feet) at the shoulder. • Weight: Between 200–400 kg (440–880 lbs), depending on the breed, sex, and regional conditions.

For comparison: • Modern cattle like Holsteins (dairy cows) stand around 140–150 cm at the shoulder and weigh 700–900 kg. • Some smaller modern breeds, like Dexter cattle, resemble ancient cattle in stature, with a height of 90–120 cm and weight of 300–450 kg.

Factors Influencing Smaller Size in Ancient Cattle 1. Nutritional Limitations: Grazing conditions were less controlled, and fodder quality was inconsistent. 2. Genetics: Ancient cattle were not selectively bred for size like modern cattle. 3. Purpose: Cattle were primarily used for labor (draught animals) and small-scale milk production, rather than for meat.

Ancient cattle were functional animals suited to the agricultural practices and available resources of their time, so their size reflected these limitations.
