Twenty four camels were randomly divided into 3 main groups. Animals of all groups were fed either 100, 50 or 25% energy content in diet for 30 days. After 30 days, camels were received daily single injections of either 1 or 2 ug galanin/kg b.wt. into their jugular veins for 5 days. Blood samples were collected daily from jugular veins of all animals before injections on day 4 until 4 days after the last injections of galanin. Samples were assayed for plasma T3, T4, GH and insulin concentrations by double-antibody RIA. Different energy contents in diet and injections of 1 and 2 ug galanin/kg b.wt. did not change the mean plasma concentrations of T3, T4 and urea in the animals of all groups. Twenty five percent energy content in diet for 30 days significantly (p<0.01) increased the mean plasma concentrations of GH and these increases were significantly (p<0.01) elevated by injection of 1 and 2 ug galanin/kg b.wt. Plasma levels of insulin was significantly (p<0.01) lower in those animals fed 25% energy and also injections of 1 and 2 ug galanin/kg b.wt. significantly (p<0.01) suppressed these low levels of insulin. The results of this experiment indicate that galanin may increase mean plasma concentrations of GH and decrease mean plasma concentrations of insulin in the camels as a pseudo-ruminants fed low energy content in diet that cause a severe body weight lost.]]>Agricultural and Food Research Council,19952nd Edn.,Amiranoff, B., A.
