Summary
Researchers identified 8 key lipid species in rooster semen that can predict fertility potential. These biomarkers, detected early in semen production, could help screen for fertility in broiler breeders.
Area of Science:
- Animal Science
- Reproductive Biology
- Lipidomics
Background:
- Sperm mobility is crucial for fertilization potential in broiler breeders.
- Identifying reliable biomarkers for fertility screening is economically important for the poultry industry.
- The lipid composition of semen is linked to sperm function and fertility.
Purpose of the Study:
- To characterize the lipidome of seminal plasma, sperm cells, and whole semen in broiler breeder roosters.
- To identify lipid biomarkers associated with different sperm mobility phenotypes.
- To investigate the impact of semen production cycle timepoints on semen lipid profiles.
Main Methods:
- Collected whole semen samples from high and low mobility roosters at different production stages.
- Utilized multiple reaction monitoring (MRM) profiling to identify and quantify lipid species.
- Analyzed lipid data using Metaboanalyst 6.0 for statistical and biomarker analysis.
Main Results:
- Identified 3241 lipid species across ten lipid classes in rooster semen.
- Found significant differences in lipid profiles between high and low mobility roosters across sample types and timepoints.
- Discovered 8 specific lipid species as excellent biomarkers for sperm mobility, detectable early in semen production.
Conclusions:
- The study provides the first comprehensive characterization of the poultry semen lipidome using MRM profiling.
- Identified lipid biomarkers can potentially be used for early screening of fertility potential in broiler breeders.
- Understanding semen lipid profiles offers insights into sperm health, storage, and productivity.

01:15Sperm Transport
5.5K
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.

16.5K
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...
