Table 1.
Breeds of Bos taurus sampled at the slaughterhouse (n = 150).

Dorsal view of the brain of a young Bos taurus.
Scale bar = 3 cm.
Table 2.
Comparisons of young (1–2 years) male (n = 10) and female (n = 17) brains sampled at the slaughterhouse.
Table 3.
Age groups of the animals sampled at the slaughterhouse (n = 150).
Fig 2.
Body and brain weight of domestic Bos taurus in the different age classes.
Light gray bars: body weight; dark gray bars: brain weight; solid line and white triangles: mean EQ. Numbers on top of the bars represent the number of specimens for each age considered.
Table 4.
Absolute and relative weights of the constituents of the encephalon of the animals sampled in the necropsy room (n = 8).
Fig 3.
Linear regression analysis between logarithm of brain weight (g) vs. logarithm of body weight (kg).
The fitted model was significant at the 5% significant level (P-value = 0.001).
Fig 4.
Graphical output from analysis of residuals of the linear regression model.
The two left-side plots refer to the normality assumption while the two right-side plots refer to the homoscedasticity and independence assumptions.
