Fig. 3From: High nutrient intake during the early postnatal period accelerates skeletal muscle fiber growth and maturity in intrauterine growth-restricted pigsEffects of the level of nutrient intake on the percentage of MyHC in psoas major muscle of pigs with different birth weights. Values are means, with their standard errors represented by vertical bars (n = 6 for each group). Mean values with different letters (a, b) were significantly different between four groups (P < 0.05). , IUGR/ANI; , NBW/ANI; , IUGR/HNI; , NBW/HNI. ANI, adequate nutrient intake. HNI, high nutrient intake; IUGR, intrauterine growth restriction; NBW, normal birth weight; MyHC, myosin heavy chainBack to article page
