Abstract: | Growth relationships between spleen and liver weights and body weight and CR length as well as between weights of liver and spleen in fetuses (145 males, 141 females) of black-white cattle. According to their body weights, the fetuses were divided into 4 growth groups: I, to 1000 g; IIa, 1000-3490 g; IIb, 3500-7990 g; III, over 8000 g. The relationships were described using appropriate allometric growth equations (log Y = b log X + A) derived both for individual groups and for the entire fetal period. Relative weights of the organs studied and the liver-spleen coefficient (L/S) were determined as well. The results are presented in equations, tables, and graphs. |
