Other Scriptural References
The Bhagavad Gita, a discourse by the god Krishna in the Mahabharata, twice refers to Kamadhenu as Kamadhuk. In verse 3.10, Krishna makes a reference to Kamadhuk while conveying that for doing one's duty, one would get the milk of one's desires. In verse 10.28, when Krishna declares to the source of the universe, he proclaims that among cows, he is Kamadhuk.
In the Anushasana Parva of the Mahabharata, the god Shiva is described as having cast a curse on Surabhi. This curse is interpreted as a reference to the following legend: Once, when the gods Brahma and Vishnu were fighting over who was superior, a fiery pillar—linga (symbol of Shiva)—emerged before them. It was that decided whoever found the end of this pillar was superior. Brahma flew to the skies to try to find the top of the pillar, but failed. So Brahma forced Surabhi (in some versions, Surabhi instead suggested that Brahma should lie) to falsely testify to Vishnu that Brahma had seen the top of the linga; Shiva punished Surabhi by putting a curse on her so that her bovine offspring would have to eat unholy substances. This tale appears in the Skanda Purana.
