Abstract
Study on nutrition metabolic rates breast muscle leg muscle and fatty acid of Saibei silkies from different Nutrition Energy (NE) levels in diet. The result showed: Nitrogen metabolic Rates of female was 56.08% when ME was 11.51 MJ kg–1 but male was 49.31% when ME was 12.34 MJ kg–1; energy were highest both female and male when ME was 12.98 MJ kg–1, metabolism energy was highest. There were significant differences in the gizzard weight proventriculus weight duodenal length jejunum length ileum length cecal length duodenal weight jejunum weight ileum weight cecal weight gizzard relative weight duodenal relative weight jejunum relative weight ileum relative weight ileum relative weight cecal relative weight between LN and HN p<0.01 LN slaughter percentage and the whole net carcass rate was high, breast muscle percentage of both and leg muscle percentage of male were increased by increasing ME but leg muscle percentage of female was not. HN crude protein contents of leg muscle of both were increased (p<0.05). ALA LA AA EPA DHA were highest when NE was 12.34 and 12.96 MJ kg–1. Essential fatty acid of leg muscle were higher than its in breast muscle. So, muscle of Saibei silkies can change ration balance of unsaturated fatty acids in body.
