title: [Cardiac weight in cattle (Bos taurus L.) during early fetal development].
abstract: 68 bovine fetuses of both sexes (37 males, 31 females) from early developmental stage (80-990 gm) were studied. The coefficient of the absolute heart weights (42.4%) and the relative heart weight (0.76%) were described. Body weight (125.9 gm) were given when the heart of the fetus reach 1 gm. For the relation between body and heart weight were found following equation: logY = 0.958 logX--2.009 and plotted on double logarythmic paper. The results from bovine fetuses were compared with analogical data for water buffalo and camel (Berg, Taher, Moustafa).
