Hypothesis
Does Landrace sperm improve fertilization rates and embryo development compared to Duroc sperm in Yorkshire × Landrace × Duroc oocytes?
Conclusion
Landrace sperm enhances blastocyst formation and gene expression related to embryo development compared to Duroc sperm.
Supporting Evidence
- Blastocyst formation was significantly higher in the LS group compared to the DS group.
- Gene expression related to pluripotency and antioxidative capacity was enhanced in embryos fertilized with LS.
- ROS levels were significantly lower in embryos fertilized with LS than those fertilized with DS.
Takeaway
This study found that using Landrace sperm helps baby pigs grow better than using Duroc sperm.
Methodology
Sperm from Duroc and Landrace pigs was analyzed for characteristics and used to fertilize Yorkshire × Landrace × Duroc oocytes in vitro.
Limitations
The study focused on sperm factors without considering oocyte quality and environmental variables.
Participant Demographics
Sperm collected from 10 Duroc and 10 Landrace boars.
