Prenatal growth and asymmetry of thyroid gland in the cattle (Bos primigenius f. taurus).

Growth and bilateral asymmetry of thyroid gland were studied in 291 fetuses (from 219 to 31,300 g) of the black-white cattle divided into 4 groups according to body weight. Relation between body weight (X) and thyroid weight (Y) was described using allometric equation Y = aXb. Allometric coefficient b was different in each of the four groups (1.198; 1.179; 1.314; 0.941) and amounted to 1.076 for the entire fetal period. The coefficient of fluctuating asymmetry of the thyroid gland decreased with increased fetal weight in the following way: 0.16; 0.10; 0.09; 0.07; this coefficient amounted to 0.02 for all the fetuses examined.

[Heart weight of the cattle (Bos taurus L.) in the middle and late periods of fetal development].

The weight heart Y-weight body relationship was studied on 219 Black-White cattle fetuses (107 females and 112 males; weight range of 1000-31,300 g). 1. The relationship in the consecutive growth periods are described by the following regression equations: middle fetal period (IIa and IIb)--IIa (n = 88, weight range 1000-3490 g) logY = 0.97 logX -- 2.05, r = 0.96; IIb (n = 68, weight range 3500-7990 g) logY = 1.04logX -- 2.29, r = 0.89; -- late fetal period III (n = 63, weight range 8000-31,300 g) logY = 1.07logX -- 2.39, r = 0.98. 2. The relationship for all fetuses, together with I prenatal period (earlier work of these authors) examined is described by the regression equation (n = 287, weight range 80-31,300 g) logY = logX -- 2.13, r = 0.99 (r -- correlations coefficient). 3. The relative heart weights are attained: IIa -- 0.72%, IIb -- 0.71%, III -- 0.77%.

[Cardiac weight in cattle (Bos taurus L.) during early fetal development].

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).
