Plants are located randomly to reduce the effect of external factors on diet selection, and to differentiate between discriminatory and random grazing. Consistency of discrimination among grazings and sites (Massey University, New Zealand and INIA La Estanzuela, Uruguay) was tested. The statistical design and subsequent analyses considered all sources of variation to minimize error, and to separate genetic effects from environment effects. Clonal replicates were used to enhance error-control, and hence the precision of heritability estimates, as most characters are inherited quantitatively. Post-grazing lea®ness is considered the best character to select and breed for animal preference in a red clover germplasm.  aOVINOS  aALIMENTACIÓN ANIMAL  aANIMAL FEEDING  aANIMAL PRODUCTIONS  aGENOTYPE ENVIRONMENT INTERACTION  aINTERACCIÓN GENOTIPO AMBIENTE  aMODEL STUDY  aMODELIZACIÓN  aMODELO ESTADÍSTICO  aOVINOS  aPASTOREO  aPLANTA FORRAJERA  aSELECCIÓN VARIETAL  aSTATISTICAL MODEL1 aGORDON, I.L.1 aHODGSSON, J.  tJournal of Agricultural Science, 2001gv. 136, no. 1, p. 111-117.
