Hypothesis
Does dietary supplementation of bile acids improve production performance and lipid metabolism in late-phase laying hens?
Conclusion
Dietary bile acids improved egg quality and reduced liver fat deposition without negatively affecting laying performance in hens.
Supporting Evidence
- Bile acids increased the total number of follicles in hens.
- Eggshell weight and yolk color improved with bile acid supplementation.
- Liver triglyceride levels decreased with dietary bile acids.
Takeaway
Feeding hens bile acids helps them lay better eggs and keeps their livers healthy.
Methodology
144 hens were divided into three groups and fed different levels of bile acids to assess their effects on egg production and liver health.
Potential Biases
Potential bias in the selection of hens and the controlled feeding environment.
Limitations
The study only evaluated short-term effects and did not explore long-term impacts of bile acid supplementation.
Participant Demographics
70-week-old Hy-line Brown layers.
