Abstract:This article systematically discusses the application of traditional Chinese medicine in lamb fattening. Through combing and analyzing relevant literature, we summarized the effects and mechanisms of traditional Chinese medicine in increasing lamb weight, promoting muscle growth, and improving immunity. We also explored the synergistic effect of the combined application of traditional Chinese medicine and trace elements such as selenium and zinc on lamb fattening. This not only provides new ideas and methods for improving the efficiency of lamb breeding, but also helps promote the application of traditional Chinese medicine in animal husbandry.
