At necropsy, the percentages of pax7+ nuclei were less (p ≤ 0.05) in the longissimus dorsi and biceps femoris and tended to be less (p = 0.08) in the semitendinosus from IUGR but not IUGR+CLEN lambs compared to controls (Figure 7A). The gene discussed is PAX7; the disease is fetal growth restriction.
