Abstract

The objective of this experiment was to investigate the effects of different levels of Milk thistle powder and Vitamin E on Liver healthy, serum parameters and production indices in Laying hens. The 2×3 factorial experiment was managed in a randomized complete design with 72 Hy-Line (W36) Laying hens in six treatments and four replicates of three birds each. The experimental period lasted for a total of six weeks. Treatments included different levels of Milk thistle powder (0, 100 and 200 mg/kg) and Vitamin E (recommended by NRC; 5 mg/kg and more than recommended by NRC; 80 mg/kg). The effect of different levels of Milk thistle powder and Vitamin E on production indices were not significant in the throughout the experimental period. The best feed conversion ratio was observed in hens fed with rations included 80 mg/kg of Vitamin E in the sixth week of experiment (P<0. 05). Laying hens were fed with Milk thistle powder (200 mg/kg) had the best feed conversion ratio compared with the control group in the fifth week of experiment (P<0. 05). The effect of different levels of Milk thistle powder and Vitamin E on Egg quality and serum parameters were not significant. Dietary Milk thistle powder (200 mg/kg), as compared with the control, decreased serum activity of alanine aminotransferase (P<0. 05). In conclusion, diet supplementation with Milk thistle powder (100 and 200 mg/kg) and Vitamin E (more than recommended by NRC) had no positive effects on production indices and Egg quality in Laying hens.
