  1. Body and muscle weight of female piglets used for the study (NBW: n = 18, LBW: n = 18). LBW piglets showed significantly lower body weight at birth and at cell isolation (day 4 of life) and also reduced percentage weight gain during this time. The mass of SM and LD muscles was reduced in LBW piglets. For statistical analysis one tailed paired t-test was performed.
