Parasuram was a kshatriya in a brahmin's body. A potion mix up with Parashuram's grandmother, Brahmin wife, and her brother's wife,Kshatriya, caused a brahmin to be born to her brother's wife and a kshatriya to be born toPArashuram's grandmother. She prayed to a rishi and the birth of the kshatriya was averted until the next generation. Thus Jamadagni's son with Renuka was a kshatriya in a Brahmin's body. Parashurama adhered to brahmin principles and vegetarianism is a big part of Brahmins. Killing animals for carnal pleasures is considered sinful and Brahmins who are expected to be the most sinless and do not require meat unlike the other castes(kshatriyas need meat to fight wars), are not expected to eat meat (Though today, some stupid brahmins do). So the answer to your question is a confident YES, assuming Parasuram existed! :)
