I looked it up since I suspected it might be cognate with “pork.”
From Proto-Slavic porsę (“piglet”), from Proto-Indo-European pórḱos. Cognate to Serbo-Croatian prase, Czech prase, Polish prosię, Slovene prašič, Bulgarian прасе́ (prasé), and Russian поросёнок (porosjónok).
I wrote 'Cows and hogs are animals' which was rated incorrect. Now Merriam-Webster lists pig and hog as synonymous: https://www.merriam-webster.com/dictionary/hog#synonyms.
