Abstract:

Gene editing is a kind of genetic engineering technology that can modify the genome. In recent years, with the rapid development of molecular biotechnology, the clustered regularly interspaced short palindromic repeats associated protein system has been widely used as a powerful gene editing tool due to its high efficiency, accuracy and flexibility. The CRISPR-Cas system makes a significant contribution to different aspects of livestock production by introducing site-specific modifications such as insertions, deletions or single base replacements at specific genomic sites. In terms of sheep production applications, by establishing animal models that improve production economic traits and disease resistance, the function of key genes can be studied to accelerate the improvement of traits, thereby accelerating the improvement of traits. In this review, we summarize the mechanism and function of CRISPR-Cas system and its application in the production of reproductive traits, meat use traits, wool production traits, lactation traits and disease resistance traits of sheep and the establishment of sheep animal models.

Key words: CRISPR-Cas system, gene editing technology, sheep, goats, production research
