Livestock systems modeller investigating the effect of twinning, multiple suckling and once calved-heifer systems on whole farm production, economic, and sustainability … WebFurthermore, twin-twin intersections were more likely to occur at cryogenic temperatures due to the coexistence of multiple variants and twin types within a grain. At a strain of 20%, higher-order sequential twinning was common during rolling at cryogenic temperature, indeed, a twinning sequence of CTW→ETW→CTW→ETW by lattice rotation was observed.
