Among feeding behavior traits, strong negative genetic correlations were estimated between TPD and FR (–0.79 ± 0.03 in YY to –0.88 ± 0.05 in LL), between NVD and TPV (–0.91 ± 0.03 in LL to –0.94 ± 0.01 in DD), and between NVD and FPV (–0.83 ± 0.05 in LL to –0.91 ± 0.02 in YY) in all 3 breeds.Among feeding behavior traits, strong negative genetic correlations were estimated between TPD and FR (–0.79 ± 0.03 in YY to –0.88 ± 0.05 in LL), between NVD and TPV (–0.91 ± 0.03 in LL to –0.94 ± 0.01 in DD), and between NVD and FPV (–0.83 ± 0.05 in LL to –0.91 ± 0.02 in YY) in all 3 breeds.
