'屠宰' (tú zǎi) is a compound word meaning 'slaughter', specifically referring to the killing and butchering of livestock such as pigs, cattle, sheep, or chickens for meat production. The first character, 屠 (tú), means 'to slaughter' or 'to butcher', often implying the act of killing animals; the second, 宰 (zǎi), means 'to slaughter' or 'to cut up', especially in preparation for food. Together, they form a formal, neutral-to-technical term used in agriculture, food safety regulations, veterinary contexts, and official reporting—not in casual speech.

This word carries no emotional connotation by itself, though it may evoke strong reactions depending on context (e.g., animal welfare discussions). It appears frequently in government documents, hygiene inspections, and factory labels—never for humans or pets. Unlike colloquial alternatives like 杀猪 (shā zhū, 'kill pigs'), 屠宰 is precise, institutional, and applies broadly across species and settings, always with an emphasis on systematic, regulated processing.
