The skin of Krishna Mrigam plays an important role in Hinduism, and Brahmin boys are traditionally required to wear a strip of unleathered hide after performing Upanayanam. It used to be one of the most abundant hoofed mammal in the Indian subcontinent, so much so that as late as early 1900s, naturalist Richard Lydekker mentions herds of hundreds in his writings, though today only small herds are seen that too inside reserves, chief reason of their decline being excessive hunting . Till Indian independence in 1947, many princely states used to hunt the Indian Antelope and gazelle with cheetahs, which became extinct in 1960s. Though the royal sport had ended, growing cultivation saw it as crop-raider, further leading to its decline. Eventually, when in the 1970s several areas reported their extinction, it was enlisted as a protected animal under the Wildlife Protection Act of 1972 .
