Haddon Big Blood's Vast Influence on Queensland Sheep
A Merino Stud Stock Register shows 24 of 50 Queensland studs using Haddon Big Blood and 11,400 rams sold in 1952. With each ram sireing about 40 lambs yearly, 456,000 lambs carry the blood, and over five years about 2,280,000 sheep are influenced. At current value, wool worth £11,400,000 to Queensland. NSW losses from rainfall lower sales to £32,00,000. Haddon Rig Blood is framed as highly profitable for pastoral interests, with Sydney Ram Sales featuring 60 two-tooth selected Stud Ewes.
