These data also confirmed that i.m. adipose tissue constant weight. In addition, postmortem cellularity data feeding resulted in more desirable carcass grades. The g tissue, smaller cell diameters, and smaller cell volumes have the greater influence on overall fatness. Calf-feeding higher in the s.c. and i.m. adipocytes of constant age impact of calf- versus yearling-feeding on differentiation of In Experiment 2, Brangus steers were fed as weanling calves indicating that age is a predominant factor in deteriming the Lipogenic rates and 3H-thymidine incorporation rates were possessed more cells per g tissue, and smaller cell diameters Postculture data demonstrated that there were more cells per replicate. The stromal vascular portion retained a greater resulted in higher dressing percentages. However, yearling- scores, and quality grades were lower in steers slaughtered showed that there were more cells per g of tissue, and smaller cell diameters and volumes from steers slaughtered at steers were fed as weanling calves (CF; n = 4) or as steers, further demonstrating the lack of maturity these subcutaneous and intramuscular adipocytes from nuclear The adipocytes from the CF constant weight treatment group these steers may be replicating.

The cloned steers were used Two parallel experiments were conducted to evaluate the was a later-developing depot. Intramuscular adipocytes weight of 530 kg.
