The Poll Highland Society Inc. can inspect cattle for registration. We register the poll, horned, and miniature highland. According to the breed standard, the standard-sized adult highland is over 48 inches, averaging about 49 to 50 inches to the regulated hip height measurement, with bulls being a few inches taller. The midsize highland measures 42 to 48 inches and the miniature measures up to 42 inches. While miniature cattle are small, they do not have a dog-like size and are still considered a significantly-sized animal. What are miniature beef cattle breeds? How can you identify them? In this post, we aim to discuss the differences between some common beef cattle breeds.
