The objective of this study was to evaluate the increasing levels (0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6%) of black pepper in diets for laying hens on performance, egg quality and blood biochemical parameters. Hissex White hens (n=168) at 30 weeks of age were used. The experimental method was completely randomized with seven treatments with four replicates of six birds each. Estimates of black pepper levels were determined by polynomial regression. The performance showed no significant differences (p > 0.05). The eggshell percentage was significantly influenced (p < 0.05), in which the level of 0.30% inclusion impaired eggshell quality. Triglycerides level increased significantly (p < 0.05), according to increasing levels of black pepper in the diet. It can be concluded that black pepper can be used in diets for laying hens as phytogenic additive without harming the performance. However, this inclusion causes a reduction in eggshell percentage and an increase in the level of triglycerides in the bloodstream.

Although many methods have been developed in order to reduce the negative effects in laying hens reared at high cage density, researches on effects of dietary supplementation of oregano (Oreganum syriacum L., OEO) essential oil as a feed additive to the diets are extremely sparse. This study investigated the effects of OEO and caging density on performance parameters, egg quality criteria, some blood biochemical parameters, blood antioxidant capacity, and intestinal histopathology of laying hens. We used 276 white Lohmann laying hens aged 38–40 weeks in the experiment. The animals were divided to positive control (600 cm2 hen/cage, PC), negative control (360 cm2 hen/cage, NC), negative control+ 200 mg/kg OEO (NC+O2), negative control+ 400 mg/kg OEO (NC+O4), and negative control+ 600 mg/kg OEO (NC+O6). In this study, it was determined that egg weight and egg shell weight increased at higher caging density, but they did not change with dietary supplementation of OEO. In addition, the plasma calcium and phosphorus decreased with the higher caging density and dietary supplementation of OEO. Supplemented OEO to the diets of the laying hens reduced lipid peroxidation and improved antioxidant capacity and intestinal histopathology of laying hens. As a result, it was determined that OEO decreased the negative effects of high caging density. While this positive effect was found to be at a maximum dose at 400 mg/kg of OEO, it was determined that a dose of 600 mg/kg of OEO had a toxic effect, if even numerically.

The aim of this study was to evaluate the effect of milk thistle seed cakes addition in laying hens diet to performance, blood biochemical parameters and antioxidant activity. A total of 30 Bovans Brown hens were included to the experiment. The trial was performed from the age of 69 weeks to 80 weeks of hens age. The experimental group received feed mixture containing 7% milk thistle seed cakes. Control group received feed mixture without milk thistle seed cakes. After the 69th week of age, the laying hens in the experimental group reached a higher number of eggs and produced more egg mass compared to the control group. In the evaluation of the egg quality parameters, higher Haugh units, a higher millimeter height of the egg and thinner eggshell in the group receiving 7% of the seed cakes were found. When evaluating health indicators, higher antioxidant activity was found in the experimental group. Blood biochemical parameters was without any differences.
