Phenotypic analyses of MSTN gene-edited sheep. A Expression levels of the MSTN gene in homozygous gene-edited (Mut) and wild-type (WT) lambs. **P < 0.01, Student’s t-test. B Birth weight of Mut and WT lambs; blue dots indicate WT founders and red dots indicate Mut founders. C Average daily gain (ADG) of Mut and WT lambs from day 0 to 90. D Changes in body weight in Mut and WT lambs from day 0 to 90. *P < 0.05, **P < 0.01, Student’s t-test. E Histological analysis of muscle tissues of Mut (#48) and a WT founder on day 180
