The effects of CT on  sheep production were assessed by  twice daily oral  administration of polyethylene glycol (PEG;   Molecular weight  4,000) to half of the lambs on each sward combination.  aCOMPORTAMIENTO ANIMAL  aCONDICION CORPORAL  aDIETA  aHOLCUS LANATUS  aINGESTION DE PIENSOS  aOVINOS  aPASTOREO  aTANINOS  aTRIFOLIUM REPENS  aANIMAL PERFORMANCE  aCONDENSED TANNINS  aDIET SELECTION  aGRAZING BEHAVIOUR  aHERBAGE INTAKE  aPERENNIAL RYEGRASS (LOLIUM PERENNE)  aWHITE CLOVER (TRIFOLIUM REPENS)  aYORKSHIRE FOG (HOLCUS LANATUS)
