چکیده

This experiment was conducted to evaluate the effects of different levels of dried aerial parts powderand extract of pennyroyal­ (Mentha pulegium) medicinal plant on performance, egg traits, blood biochemical and immunity parameters of laying hens. Two-hundred-fifty-two Hi-line (W36 strain) laying hens from 46 until 58 weeks of age were used in a completely randomized design in 7 treatments and 3 replicates (12 birds per replicate). The treatment groups consisted of a control group (1) with no dried aerial parts powder or extract of pennyroyal­ supplementation, and experimental groups 2, 3 and 4 contained 0.5%, 1% and 1.5% of pennyroyal­ powder respectively, whereas experimental groups 5, 6 and 7 contained 0.1%, 0.2% and 0.3% of pennyroyal­ extract, respectively. Using different levels and forms of pennyroyal­ significantly affected the performance, egg traits, blood biochemical and immunity parameters of laying hens (P<0.05). By increasing the level of pennyroyal­ extract to 0.2% and 0.3% of rations, the performance of laying hens significantly decreased, whereas pennyroyal­ powder improved the performance of laying hens, consequently the best feed conversion ratio (2.46) was achieved by using 1.5% pennyroyal­ powder. The highest specific gravity (1.092) and Haugh unit (89.22) were resulted in groups 5 and 6, respectively. The lowest amount of blood triglyceride (270.4 mg/dL) and the highest amounts of albumin (3.05 mg/dL), total protein (5.40 mg/dL) and uric acid (5.39 mg/dL) were observed in group 7. The lowest percent of hetrophil (9.67%) and the highest percent of lymphocyte (90%) were observed in group 2 and the highest amount of white blood cells (266601/mm³) was resulted in group 5. The overall results showed that the use until 1.5% of dried aerial parts powder and 0.1% of pennyroyal­ (Mentha pulegium) extractcompared with control group had positive effects on performance of laying hens. Using different levels of pennyroyal­ powder and extract could change the egg traits, blood biochemical parameters and immunity levels of laying hens.
