This preliminary study quantified the size and number of adipocytes within Longissimus lumborum intramuscular fat across 5 postnatal stages of growth and 2 post-weaning forage-based feeding systems in Bos taurus genotypes selected to differ in their fat distribution. No differences (P>0.05) in size or number of adipocytes due to feeding system were evident. Adipocyte size was lower (P<0.05) for Hereford than Angus and Wagyu × Angus steers. Overall, number of adipocytes for Hereford was lower than for the other genotypes, although did not differ significantly (P>0.05) within each stage of growth. Stage of growth affected size and number of adipocytes (P<0.05).
