Effect of different levels of wild pistachio leaves (Pistacia atlantica), on liver enzymes, blood parameters and performance indicators of broiler chickens

To evaluate the effect of different levels of wild pistachio leaves on liver enzymes, bloodparameters and performance indicators of broiler chickens, 192 one-day old Ross 308 broiler chickens in the completely randomized design, including 4 treatments, 4 replicates and 12 chicks (both sexes), per experimentalunits were used. The experimental treatments includedrationscontaining levelsofzero (control), 1, 2, and 3 percent of wild pistachio leaf powder. The results of this experiment showed that effect of wild pistachio leaf on feed intake and daily gain significantly reduced compared to control treatment in the initial period (P˂0.05), but feed intake and daily gain were not significant in the growth period and total period.The feedconversion ratio was not significantly affected (P > 0.05). The effect of experimental treatments was not significant on AST and ALT, but the ALP enzyme was significantly reduced by the experimental treatments (P˂0.05). The amount of glucose, total cholesterol and HDL cholesterol of serum were not significantly affected. The effect of experimental treatments on triglyceride and LDL cholesterol serum reduction was significant (P˂0.05). According to the results, wild pistachio leaf can be used as an additive plant with reducing feature on liver enzymes and triglyceride and LDL cholesterol in poultry diets.
