Table 6 Differences between adjusted weaning weights of twin-born, twin-reared and triplet-born, triplet-reared lambs (expressed as twin – triplet) in high- versus low-performance flocks from the TBR = 33 dataset by applying different adjustment protocols

From: Effects of birth-rearing type on weaning weights in meat sheep are systematically associated with differences in mean performance among flocks

Adjustment protocol Flock performance level Difference (low – high)
Low High
Simple additive 0.18 ± 0.55 0.03 ± 0.58 0.15 ± 0.80
Simple multiplicative 0.97 ± 0.52 −0.85 ± 0.55 1.82 ± 0.76*
Flock-specific multiplicative −0.03 ± 0.69 0.71 ± 0.73 −0.74 ± 1.00
Simple multiplicative with interaction 0.97 ± 0.52 −0.84 ± 0.55 1.81 ± 0.76*
Flock-specific multiplicative with interaction −0.03 ± 0.69 0.71 ± 0.73 −0.74 ± 1.00
  1. Based on five (of 20) flocks with the lowest flock means and five flocks with the highest flock means for weaning weight in the TBR = 33 dataset (Table 1); , *: P < 0.10 and 0.05, respectively
