Depth of backfat and KPH percentage were not affected (P = 0.44
and 0.80, respectively) by vitamin A restriction.
// Carcass weight, composition of edible carcass, and yield grade were similar among treatments (P > 0.10).
// Liver retinol (LR = 6.1, SR = 6.5, and control = 44.7 g/g; P < 0.01) was reduced in LR and SR vs.
// control steers.
// On d 243, LR and SR steers had similar serum retinol concentrations, and these were lower (P < 0.01) than those of control steers (LR = 21.2, SR = 25.2, and control = 36.9 g/dL).
// Intramuscular adipose cellularity (adipocytes/mm2 and mean adipocyte diameter) on d 112 and 243 was not affected (P > 0.10) by vitamin A restriction.
// Restricting vitamin A intake for 243 d increased i.m. fat percentage without affecting s.c. or visceral fat deposition, feedlot performance, or carcass weight.
// Restricting vitamin A intake for 131 d at the end of the finishing period appears to be insufficient to affect the site of fat deposition in Holstein steers
