This correction notice addresses inaccuracies in an article about two products used in the animal breeding industry in China. The names of the products and a picture were incorrectly used, and the term "impurity" should be replaced with "trace components." The correction provides the accurate names of the products and clarifies their use as safe and effective Chinese veterinary medicine. Additionally, errors in figures and sample preparation information are corrected. The scientific conclusions of the article remain unaffected by these changes. [Extracted from the article]
