请翻译为了避免掺混不同豆粕产品。15日不得不仅将夜班生产45蛋白含量的豆粕的相关样品单独制作。所以样品记录中13日-15日的样品为生产45含量蛋白豆粕的相关样品。

In order to avoid confusion with different soybean meal products, we had to produce separate samples of soybean meal with a 45% protein content during the night shift on the 15th. Therefore, the samples recorded from the 13th to the 15th are related samples of soybean meal with a 45% protein content.
