Dietary supplementation with carbamoyl aspartate at 800 milligrams per kilogram significantly reduces hepatic lipid accumulation and abdominal fat deposition in broilers fed a high-fat diet. The intervention targets lipid metabolic disturbances linked to intensive farming and obesity in poultry.
Translational Medical Insights for Clinical Practice
- Mechanism of Action: Carbamoyl aspartate acts as a pyrimidine biosynthesis intermediate, modulating metabolic pathways associated with lipid storage.
- Metabolic Targets: Network pharmacology screens have identified phosphodiesterase 4B (PDE4B) as having the most favorable predicted docking interaction among twenty-two candidate targets.
- Tissue Impact: Supplementation successfully decreases liver weight, hepatic triglyceride and total cholesterol levels, while simultaneously improving meat color and muscle yield.
Reducing High-Fat Diet Lipid Accumulation in Broilers
Obesity presents significant physiological challenges across both human and agricultural health sectors. Intensive farming practices frequently exacerbate metabolic disorders, notably fatty liver disease in poultry, where safe and effective nutritional interventions remain severely limited. To address this gap, recent experimental evaluations investigated the administration of carbamoyl aspartate (CA).
In both in vitro assays utilizing HepG2 cells and in vivo trials involving broilers, CA demonstrated a measurable capacity to reduce hepatic triglyceride accumulation. Broilers subjected to a high-fat diet supplemented with 800 mg/kg of CA exhibited significant reductions in overall liver weight, hepatic triglyceride and total cholesterol levels, and abdominal fat deposition, with statistical significance established at $P < 0.05$. The nutritional intervention also improved meat color and muscle yield.
Carbamoyl Aspartate Targets PDE4B to Regulate Lipid Metabolism
To uncover the biological pathways driving these metabolic improvements, network pharmacology was employed to map compound-target-pathway-disease associations. Researchers identified 22 candidate targets directly linking carbamoyl aspartate to lipid metabolism regulation.
Among these screened candidates, PDE4B showed the most favorable predicted docking interaction with the compound. While these network models suggest a multi-target molecular association, researchers emphasize that these predicted mechanisms require comprehensive further validation before broader translational applications can be fully realized.
