Fig. 1From: Effects of birth-rearing type on weaning weights in meat sheep are systematically associated with differences in mean performance among flocksRelationship between adjustment factors and flock means for birth weight. Additive or multiplicative factors (Y) that are required to adjust birth weights of single lambs to a twin-lamb basis are plotted against flock means for birth weights of twin lambs (W). Prediction equations were derived by weighting each observation by the number of single-born lambs in the flockBack to article page
