Dietary Treatments

This study examined the effects of Mentha arvensis (MA) and Geranium thunbergii (GT) extracts in drinking water on the production performance, egg quality, cholesterol content of egg yolk, proximate composition, and sensory qualities of egg and immunity parameters in laying hens. Ninety-six 28-week-old Hy-Line Brown layers were randomly divided into four dietary treatments for 16 weeks. The dietary treatments were (1) control, (2) T1 (0.01% 1 MA:1 GT), (3) T2 (0.05% 1 MA:1 GT), and (4) T3 (0.1% 1 MA:1 GT). Egg production increased significantly with increasing levels of MA and GT. The egg weight was increased in T2, and the feed intake was highest in T2 and T3 (p < 0.05). The Haugh unit and egg shape index were significantly better in T3 and the control than with other treatments (p < 0.05). The content of yolk cholesterol was significantly lower (p < 0.05) in T2 and T3. On the other hand, there were no significant differences in the egg proximate composition. A significant increase in the serum interleukin 6 (IL-6), tumor necrosis factor (TNFα) and immunoglobulins (IgG and IgA) concentration was observed in the birds fed plant extracts when compared to the control. On average, T2 and T3 showed significantly lower (p < 0.05) concentrations of NH3 gas from the feces as compared to the control. This study suggests that MA and GT supplementation could improve the laying performance, egg quality, and immunity, and decrease the egg yolk cholesterol content in a dose-dependent manner.

Abstract This study was conducted to investigate the effects of Pleurotus eryngii stalk residue (PESR) on performance, egg traits and oxidative status of laying hens. One hundred and twenty 22-week-old laying hens (Hendrix) were randomly allocated into 4 dietary groups, each containing 30 birds, including 10 replicates per group and 3 birds per replicate. In addition, they were fed diets supplemented with 0 (control group, corn-soybean meal), 0.5, 1.0, or 2.0% dried PESR groups for 8 weeks, respectively. The results indicated that the different levels of dietary supplementation produced no significant differences in production performance among the experimental groups of laying hens. The Haugh unit was significantly higher in the 1.0% and 2.0% PESR groups compared to the control group. The eggs’ cholesterol content of the 1.0% and 2.0% PESR groups was significantly lower than that of the control group at 5-8 weeks. The blood triglyceride content and cholesterol content were significantly lower in the 1.0% and 2.0% PESR groups compared to the control group at the 4th and 8th weeks. Hence, the supplemented 1.0% and 2.0% of PESR groups showed higher levels for serum trolox equivalent antioxidant capacity, catalase and superoxide dismutase during the experimental period in comparison with the control group. This study indicated that a by-product of Pleurotus eryngii, PESR, could produce lower-cholesterol eggs and improve the oxidative stability with 1.0% and 2.0% PESR supplementation in laying hens.
