Castration and sadistic mutilation of slaves remained standard in Spanish America.

Evidence

In Spanish America the lash, the stock, detention, and deprivation were standard means by which unruly and defiant slaves were kept in line. Some masters were known to have whipped their bondmen to death, while others continued to mutilate their dusky properties with hot branding irons even after the crown had prohibited this act. Worst of all were the vengeful sadists who made their slaves eat excrement and drink urine. — Cedric J. Robinson, Black Marxism_ The Making of the Black…, 643
