The vitamin A concentration was determined in 89 Australian brands of commercial foods for dogs and cats. It was found that 8% of the dog foods and 14% of the cat foods had concentrations of vitamin A below the minimum recommended 1.1 mg/kg dry matter (dm) for dogs and 1.8 mg/kg dm for pregnant or lactating cats. Canned and fish-labelled cat foods were the only varieties with less than the minimum recommended concentration of Vitamin A, of which 71% were the same brand. The minimum recommended concentration of vitamin A was exceeded in all canned dog food tested. Concentrations of vitamin A in dry (ca. 6% moisture) dog and cat foods and semi-moist dog foods (ca. 23% moisture) never exceeded 10 mg vitamin A/kg dm. In contrast, canned pet foods stated to contain liver or kidney showed vitamin A concentrations from 13 to 284 mg/kg dm.
对89个澳大利亚品牌的猫狗商业食品中的维生素A浓度进行了测定。结果发现，8%的狗粮和14%的猫粮中维生素A浓度低于犬类最低推荐的1.1毫克/千克干物质（dm）以及怀孕或哺乳期猫的1.8毫克/千克干物质。罐装和标有鱼类的猫粮是仅有的维生素A浓度低于最低推荐浓度的品种，其中71%为同一品牌。所有测试的罐装狗粮中维生素A浓度均超过了最低推荐浓度。干制（约含6%水分）的狗粮和猫粮以及半湿狗粮（约含23%水分）中的维生素A浓度从未超过10毫克维生素A/千克干物质。相比之下，标明含有肝脏或肾脏的罐装宠物食品中维生素A浓度为13至284毫克/千克干物质。
