《淮南子·时则训》
还要命令主管祭祀的官员，巡视检查那些准备用来祭祀的牲畜，察看肥瘦是否适中，是否完好无缺，毛色是否纯正，体形大小是否符合等级类别，重量齿龄是否符合规定标准。
乃命宰祝行牺牲，案刍豢，视肥臞全粹，察物色，课比类，量小大，视少长，莫不中度。
Also, order the officials in charge of sacrifice to inspect the animals to be used for sacrifice, check whether they are fat or thin, whether they are intact, whether their fur is pure, whether their size is consistent with their grade, and whether their weight and age meet the specified standards.
