Abstract :
To evaluate the effect of different levels of zinc glycine and zinc hydroxide on blood and immunity parameters, and enzyme activity in broilers in a compeletely randomize design with 9 treatments and 4 replications and 15 chickens in each experimental unit by 3 × 3 factorial method was performed on 540 one- day- old broiler chickens on top of 308. Experimental diets included different levels of 0, 50 and 100 mg/kg from each of the two sources of zinc hydroxide and zinc glycine. Experimental results showed that the effect of different levels of zinc hydroxide on performance, cholesterol, triglyceride, HDL, LDL, VLDL, SRBC antibody titer (immunoglobulin M first and G second), Newcastle antibody titer and influenza were significant in both turns, white blood cells number, percentage of heterophiles and lymphocytes, immune organs,, Enzymes alanine transaminase(ALT), aspartate transaminase(AST), alkaline phosphatase(ALP), lactate dehydrogenase(LDH) and superoxide dismutase(SOD) were significant (P<0.05). The effect of different levels of zinc glycine on glucose, liver enzymes, immunoglobuline G second time, thymus,(P<0.05).The overall results showed that feeding broilers with the diet including 100 mg/kg of zinc hydroxide had the appropriate effect on broilers.
