Chemical Defleecing of Sheep under Two Divergent Diet^{1, 2,}

Texas Tech University, Lubbock 79409³

Abstract

Trial I. Fifty-one mature white-face ewes were randomly assigned within three dosage levels of cyclophosphamide (CPA); 6.8, 9.0 and 11.4 mg/lb. of body weight, (15, 20 and 25 mg/kg body weight). These ewes were fed a limited allowance, (1.5 lb./day) (0.68 kg/day) of an all-concentrate ration. Least-squares means for days elapsing between dosing and defleecing for the 6.8, 9.0 and 11.4 mg/lb. (15, 20 and 25 mg/kg) groups were 18.7, 15.8 and 14.3 days, respectively, with the 6.8 mg/lb. (15 mg/kg) treatment being significantly different (P< .01) from the other two. The 6.8 mg/lb. (15 mg/kg) group had a minor (P< .05) advantage in regrowth at time of defleecing, but this was not evident when .24 in. (0.6 cm) wool regrowth interval was measured. All treatment groups were characterized by a high feverish state at time of defleecing, which persisted for 7 to 10 days thereafter. Defleecing was easily accomplished over all body areas.
