Abstract This study aimed to investigate the effects of high and low levels energy intake during entire gestation period on skeletal muscle development, organ adipose tissue accumulation in fetuses Wagyu (Japanese Black) cows, a breed with highly marbled beef. Cows were allocated high‐nutrition ( n = 6) group (fed 120% nutritional requirement) or low‐nutrition 60% requirement). The cows artificially inseminated semen from same sire, removed by cesarean section at 260 ± 8.3 days fetal age slaughtered. whole‐body, total muscle, adipose, bone masses half‐carcasses significantly higher than p 0.0018, 0.009, 0.0004, 0.0362, respectively). Fifteen 20 individual muscles, five six fat depots, nine 17 organs, seven 12 bones that investigated had group. crude components amino acid composition longissimus differed between low‐ groups. These data indicate maternal nutrition has marked effect bone, development cattle fetuses.
