| Abstract: | This experiment was conducted to investigate the effects of different nutritional levels on muscle histological characteristics of lambs.Eighty castrated Mongolian lambs were randomly divided into four equal groups.Lambs in the control group(group C) were fed a diet(ME 10.88 MJ/kg,CP 15.00%) ad libitum;lambs in the moderate restriction groups(groups R1 and R2) were fed restriction diets(ME 10.88 MJ/kg,CP 10.00% and ME 9.41 MJ/kg,CP 10.00%,respectively);lambs in the severe restriction group(group R3) were fe... |
