Comparable to the body weights, the organ weights
showed a similar, continuous growth pattern from 3 to 9 mo
of gestation (Table 4). Increase of liver, lung, and heart
weights from 6 to 9 mo was 2- to 3-fold greater than the
increase from 3 to 6 mo. The kidney weight increased, in
contrast to the other organs, linearly throughout the
gestation from 3 to 9 mo. This is the first report of such data
in cattle. Richardson et al. (1991) reported Jersey fetuses
