 note = {application/pdf, Dairy cattle management lacks consideration of fetal breed, the effect of which on fetal growth and nutrition are unclear. We investigated blood parameters in 12 late- pregnant Holstein heifers with similar (Holstein, n= 5) or different (Japanese Black [n= 4] or F1 cross [n= 3]; Holstein × Japanese Black) fetus breeds and in their um-bilical  cords  and  calves.  Samples  were  obtained  from  dams  1  week  before  calving  (−1  week)    and   immediately after    calving, from   the  umbilical vein   at  calving, and   from   calves immediately after birth. Dams with beef fetuses had higher serum glucose lev-els   (−1   week; p< .05) than those with Holstein fetuses. Plasma total amino acid, total essential amino acid, total nonessential amino acid, and other amino acid concentra-tions were lower in the umbilical veins of dams with calves of the beef breeds than in those of the Holstein breeds (p< .05). Furthermore, serum glucose and plasma amino acid levels were lower in the beef calves than in the Holstein calves (p< .05). Overall, nutrient supply from dams to beef fetuses was lower than that to Holstein fetuses. Our findings may facilitate feeding management of dairy cattle pregnant with beef breeds for ppropriate fetal growth and nutrition.},
