Its feeding requirements and health Received 3 December 2013 status must be determined in order to optimize its culture conditions. The present study looked at the Received in revised form effects of different dietary protein levels (47 or 52%) in combination with 3 lipid levels (10,15 or 20%) on the 14 January 2014 immune system of juvenile shi drums. Most immune parameters assessed were affected by the dietary Accepted 9 February 2014 treatment. The ceruloplasmin activity, the whole blood respiratory burst activity, the serum myeloper- Available online 20 February 2014 oxidase activity, the antibacterial activity of serum lysozyme and the serum antiprotease activity all varied with the dietary protein/lipid ratio. In view of these results, the lowest
