Table 2 Growth performance data, skeletal muscle weights, muscle protein concentrations and muscle triglyceride concentrations of rats fed diets without (Control) or with supplemented carnitine (Carnitine)

From: Supplementation of carnitine leads to an activation of the IGF-1/PI3K/Akt signalling pathway and down regulates the E3 ligase MuRF1 in skeletal muscle of rats

  Control Carnitine
Food intake (g/d) 26.3 ± 2.4 25.8 ± 2.1
Final body weight (g) 353 ± 31 334 ± 28
Feed conversion ratio (g feed/g BWG) 3.11 ± 0.54 3.20 ± 0.44
Muscle weights (g)   
M. quadriceps femoris 1.08 ± 0.08 1.09 ± 0.07
M. EDL 0.51 ± 0.07 0.52 ± 0.09
M. gastrocnemius 1.86 ± 0.09 1.90 ± 0.08
M. soleus 0.15 ± 0.01 0.15 ± 0.02
Muscle protein concentration (mg/g wet tissue)
M. quadriceps femoris 108 ± 10 111± 11
M. EDL 102 ± 9 113± 10*
M. gastrocnemius 108 ± 15 111± 15
Muscle triglyceride concentration (mg/g wet tissue)
M. quadriceps femoris 1.42 ± 0.66 1.28 ± 0.46
M. EDL 1.06 ± 0.43 0.84 ± 0.17
M. gastrocnemius 1.29 ± 0.32 1.24 ± 0.33
  1. Values are means ± SD (n = 12/group). * indicates a significant difference to the control group (P < 0.05). BWG: body weight gain; M: musculus; EDL: extensor digitorum longus.
