Increased Pasture Profits through South African Dorper Sheep
Superior growth and carcass quality can enhance profits from grasslands and grazing systems.
Objective: To determine economic feasibility of introducing South African Dorper Sheep genetics into a pasture-based farm flock.
Methods: The project coordinator planned to utilize Laproscopic Artificial Insemination to introduce Dorper genetics into a polypay flock and compare gain and carcass quality of pasture-finished Dorper cross lambs with purebred polypay lambs.
Results: Due to extremely dry conditions, lambs were fed 0.5 lb per day of grain for the last 60 days. However, Dorper cross lambs were 5 lbs heavier at slaughter, with 1 percent higher dressing pct, 0.01 inch lower backfat, larger loin eye and a higher leg score.
