Researchers at the Federal University of Parana in Brazil have initiated a project to synthesize donkey collagen in a laboratory setting, aiming to replicate the molecular structure of the protein currently extracted from the hides of slaughtered animals. This scientific effort seeks to address the supply chain pressures created by the international trade in ejiao, a traditional Chinese medicine valued for its purported anti-ageing and health-restorative properties.
The Scientific and Commercial Objective
The project, led by Carla Molento, a professor of animal welfare and head of the university’s Cellular Animal Science laboratory, focuses on developing a scalable method for producing collagen that matches the properties of the traditional product. By shifting production to a cellular level, the team aims to provide an alternative to the current industry reliance on donkey skins, which requires the processing of live animals.
The primary technical challenge involves ensuring the laboratory-grown collagen maintains the purity required for medicinal applications. Beyond the potential for animal welfare improvements, the researchers contend that a synthetic alternative could reduce the risk of biological contamination, a persistent concern in the unregulated or clandestine processing of animal hides. The initiative is positioned as a potential solution to the supply-demand imbalance that has led to a significant decline in global donkey populations, particularly in regions where the animals are sourced for export to the Chinese market.
Market Dynamics and Industry Impact
The global demand for ejiao has historically driven a market where donkey skins are treated as a high-value commodity. This demand has incentivized large-scale slaughter operations, often outstripping the natural reproduction rates of donkey populations in several countries. The resulting scarcity has driven up prices and spurred reports of widespread theft and illegal trade in regions where donkeys serve as essential working animals for local agriculture and transportation.
While the Brazilian research team views the project as a way to decouple the medicine’s production from the live animal trade, the transition from experimental laboratory synthesis to industrial-scale manufacturing remains a significant hurdle. The process requires navigating complex regulatory landscapes regarding the certification of synthetic animal products intended for human consumption or pharmaceutical use.
Institutional and Regulatory Landscape
The development of lab-grown collagen occurs as international organizations and agricultural ministries continue to evaluate the impact of the hide trade on rural livelihoods. In various jurisdictions, the trade has prompted debates over whether to classify donkey skins as essential trade goods or to implement strict export bans to protect domestic animal stocks. The Federal University of Parana’s work is currently undergoing internal quality assurance testing to determine if the synthesized collagen can achieve bio-equivalence with traditional sources.
The laboratory has scheduled a series of peer-reviewed assessments to evaluate the molecular stability of the collagen prototypes over the next fiscal quarter. Following these assessments, the researchers intend to present their findings to international food and drug safety authorities to determine the feasibility of a commercial pilot program.
