‘饲料’ (sì liào) literally combines ‘饲’ (to feed, especially animals) and ‘料’ (material, substance, or ingredient), meaning ‘animal feed’ — the food specially formulated and provided to livestock, poultry, fish, or pets. It is a compound noun used almost exclusively in agricultural, veterinary, and aquaculture contexts, not for human food. Unlike general terms like ‘食物’ (food), ‘饲料’ implies purpose-built nutrition: often processed, nutrient-balanced, and commercially produced.

This word appears frequently in farming reports, animal husbandry guidelines, and regulatory documents about food safety and animal welfare. It may refer to dry pellets, silage, premixes, or supplementary additives. While ‘饲’ alone can be a verb (e.g., 饲养 — to raise/keep animals), ‘饲料’ functions only as a noun and never as a verb. It is neutral in register — appropriate in both technical writing and everyday farm talk — but would sound unnatural in casual conversation about pets unless discussing nutrition specifically.
