Without a dought the DORPER ... anything else and it will cost you more money to raise in this day and age. Google Dorper, Dorpers for Sale, etc. and you will get a very good idea of what I mean. Proportionally they produce more meat per animal than the other types on less feed. As for wool... it will cost you more to shear than what the wool is worth. Docking is much more adventagous especially for preventing fly strike as maggots will infest the dirty back end regions and start to eat the lamb's flesh causing extream pain. Treatment is costly and labor extensive. I have raised hundreds of lambs so I just may have an inkling as to what to raise efficiently to make a profit.
