Fat-free body (FFBM) and body-fat masses measured at study end (d 42) by chemical carcass analysis and partitioning of fat between the TAT and non-TAT compartments of chow-fed intact (CH-Intact; n = 6) and ovariectomized rats (CH-OVX; n = 7). FFBM is body mass - body fat. Fat content of TAT was calculated using the factor of 84% determined in the present study. Data (mean ± SEM) are absolute levels and, for fat data, are also normalized to FFBM. Data were analyzed by t-tests.
