“…Phase two, experimental design as described previously, showed that M1 and F4 had different Weaning weight differed between crossbred and purebred calves in which crossbred animals were on average 15 kg heavier in the first study and on average 27 kg heavier in the second study compared to purebred calves (Northcutt et al, 1990). While these results would show strong genotype by environment interaction, other studies have shown no significance (Tess et al, 1984). It was reported by Tess et al (1984) that no significant sire x location interactions were present for birth weight, preweaning average daily gain, and weaning weight in North Carolina among three locations (Mountain, Piedmont, and Coastal Plain regions of the Southeast).…”
