Conteúdo: | Skin folds were recorded and evaluated on 760 rams and 915 ewes of the Rambouillet breed. The records were taken on freshly shorn yearlings The males had significantly greater skin-fold values than the females. The skin-fold values of all body regions were highly and significantly correlated with each other, with total skin folds and with total mines the part correlated. Regression coefficients for estimating the total skin folds from the record of a part differed by one in each case from those using total minus the part. Either may be used, but that using total skin folds is simpler. The neck regions, top and bottom, may be used either separately or together with a fairly high degree of reliability to replace the record of the entire animal. Analysis of variance and covariance of parent-offspring groups was made with the progeny of 29 sires. This showed a significant influence of sires.
