Domestic rhinoceros (SciiFii)

The domestic rhinoceros (Ceratotherium tauros) is a species of rhinoceros that originally did not exist, but has since been created by SciiFii and sold throughout a world as a common livestock/farm animal, which is farmed for its ivory horn, to help combat poaching. The closest living relative of the domestic rhinoceros is the white rhinoceros (Ceratotherium simum). Compared with its closest relative, the domestic rhinoceros is much more adapted at feeding on a wider range of grasses and shrubs, and is much more tolerant to captivity-related stresses unlike most rhinoceroses. The domestic rhinoceros is one of the only species of rhinoceros that is completely docile and tame around sapient species along with other domesticated species, most likely due to SciiFii's scientists who tampered with the aggression-related genes, to make the domestic rhinoceros suitable for farming. The domestic rhinoceros comes in more than 125 breeds worldwide, ranging from the smallest breeds that are about the size of a medium-sized pig to the largest breeds that are about the size of a white rhinoceros, and all breeds have a single horn, either short or long, due to the demand for ivory. Thankfully for the rhinoceroses, the rhinoceros' horns are sheared off without harming the animal, and the horns grow back around 3-4 months later. The domestic rhinoceros is also a very fast and frequent breeder, with its reproduction about as fast, frequent, and easy to breed as a domestic cattle's reproduction, to make the species favorable for captive breeding. The domestic rhinoceros is one of the most popular of the genetically-engineered livestock, being found in almost every single farmland, rural areas, and, for the small breeds, is even common as backyard pets, due to the rhino's tameness, docile nature, and its readiness in captivity.
