The first settlers in the 16th century brought the cattle from the iberian peninsula to Brazil that eventually resulted in the evolution of the Pantaneiro cattle (Bos taurus primigenius). These cattle represent many generations of natural selection in the Pantanal region and their ability to adapt to the region. Presently, conservation efforts are necessary to prevent the Pantaneiro cattle from becoming extinct. In the years from 1994 to 1997, the scrotum circumference and body weight were measured repeatedly in 47 young Pantaneiro bulls, 8 to 30 months of age. The data were used to estimate correlations between those traits. The body weight and scrotal circumference were 108 kg and 15 cm at 240 days of age; 137 kg and 18 cm at 365 days; and 181 kg and 23 cm at 550 days. Linear, quadratic and cubic regression estimates between scrotum circumference and age bulls were significant. Similary, the linear correlation between body weight and age, and between scrotal circumference and and body weight were significant. The estimates of correlations that ranged from 0.83 to 0.85 indicate selection in the Pantaneiro cattle for increased body weight should promote an increase in scrotal circumference. |
