Lot 12 is a true herd sire prospect that is hard to fault with his terrific phenotype, superb individual performance, and enviable heritage. Mack Donald is a well balanced, heavy muscled, and structurally sound prospect with tremendous length of body. He combines the antagonistic traits of low birthweight and high performance flawlessly. His Pathfinder dam records 4@97 BWR and 4 @ 108 WWR with a 364 day calving interval. Plus, she is a full sister to the dam of Reference Sire A, WRA Whitley. On top of all this, Mack Donald has a wonderfully quiet disposition—scratch his back and you will have a friend for life. Selling 2/3 interest and full possession.
