An Experiment to Determine the Relative Growth and Productivity of Rams and Wethers Under Identical Field Conditions

The effects of castration on meat production in cattle, sheep and pigs

“…Skin, fleece and feet were not separated in these sheep and no effect of treatment was apparent: however, it is likely that a similarity in fleece weight would mask any difference in skin weight. Riches & Johnstone (1949) compared the fleece weights of rams and wethers and found no difference in the first clip taken at 9 months of age though rams yielded 1-65 and 1-0 lb. more wool per head at 18 and 28 months of age.…”
