Short summary
Short summary
The effect of adding propolis to high-energy feed for laying hens on performance values and ratio of liver fat was investigated. High-energy feed adversely affected egg production and liver fat ratio, but the addition of 100 or 200 mg kg-1 of propolis improved egg production and decreased liver fat ratio.

Short summary
Short summary
The addition of 1 mL kg−1 pomegranate seed oil (PSO) to feeds improved performance. The addition of PSO had a positive effect on shelf life, and it increased punicic acid and conjugated linoleic acid (CLA) levels without reducing egg quality.

Short summary
This study evaluated the effects of pomegranate peel supplementation (0, 50, 100, and 150 mg kg-1) in high-energy diets for laying hens. The results indicated that 150 mg kg-1 supplementation improved egg production, feed conversion ratio, shell strength, and yolk color while reducing triglyceride and very-low-density lipoprotein (VLDL) cholesterol levels. Additionally, the liver fat ratio was decreased with 100 and 150 mg kg-1 supplementation. Further research is needed for more detailed findings.
