In the rural stretches of Campo Largo, Chaco, the intersection of academic theory and agricultural practice recently took the form of a large-scale health intervention. At a cage-free egg production farm owned by producer Facundo Costiuk, a collaborative effort between veterinary students and agricultural experts culminated in the vaccination of 5,800 hens to prevent the spread of the avian pox virus.
The initiative serves as a critical component of the farm’s established sanitary calendar, a preventative strategy designed to shield poultry populations from viral outbreaks that can devastate local production. By integrating fifth-year Veterinary Science students from the Universidad Nacional del Chaco Austral (UNCAUS) into the process, the program bridged the gap between classroom instruction in “Bird Production” and the visceral realities of field medicine.
As a physician and medical writer, I recognize that the principles of zoonotic and animal health are often mirrors of public health strategies. The rigorous approach seen in this avian pox vaccination training—moving from theoretical pathology to precise clinical application—is the gold standard for preventing outbreaks that could otherwise ripple through the regional food supply chain.
The Mechanics of Avian Pox Prevention
The training was structured in two distinct phases to ensure that the participants—which included farm staff, producers, and students—fully understood the “why” before the “how.” The theoretical session focused on the Avipoxvirus, the agent responsible for the disease. Experts detailed the virus’s causal agent, its modes of transmission, and the clinical presentations that signal an infection.
Avian pox typically manifests in two forms: the cutaneous (dry) form, characterized by nodular lesions on unfeathered areas like the comb and wattles, and the diphtheritic (wet) form, which affects the mucous membranes of the mouth, and throat. Both can lead to significant production losses due to respiratory distress or secondary infections. For a cage-free operation, where birds have more interaction with their environment and potentially with insect vectors like mosquitoes, a strict vaccination schedule is non-negotiable.
Following the lecture, the focus shifted to the practical application of the vaccine. This stage was not merely about the administration of the medicine but about the holistic handling of the animals. Correct manipulation is essential to minimize stress in the flock, which can otherwise suppress the immune response and undermine the efficacy of the vaccine.
Under the guidance of technical experts, the students and staff organized into working groups to execute the vaccination of the 5,800 hens. This hands-on experience allowed students to master the specific technique required for the avian pox vaccine, which typically involves a precise application to the wing web of the bird.
A Collaborative Model for Rural Development
The success of the event relied on a multidisciplinary team of specialists. The technical guidance was provided by Omar Zlatanoff from the Instituto Nacional de Tecnología Agropecuaria (INTA), alongside UNCAUS faculty members Méd. Vet. Jorge Juárez, a professor and head of practical work, and Ing. Zoot. Antonela Malina, an auxiliary professor.
This partnership between the Universidad Nacional del Chaco Austral and the INTA EEA Las Breñas represents a strategic alignment of interests. While the farm receives professional health services and the birds are protected, the students gain indispensable clinical hours. This “learning-by-doing” model is vital for producing veterinarians who are comfortable in the field, not just the laboratory.
The emphasis on cage-free production further highlights a shift toward more sustainable and ethical farming practices in the Chaco province. Cage-free systems, while improving animal welfare, require more vigilant sanitary management due to the fact that the birds’ increased mobility can facilitate the spread of pathogens if preventative measures, such as the avian pox vaccine, are neglected.
Key Components of the Training Program
| Phase | Focus Area | Key Learning Objective |
|---|---|---|
| Theoretical | Viral Pathology | Understanding transmission and clinical signs of Avipoxvirus. |
| Technical | Animal Handling | Reducing bird stress during medical interventions. |
| Practical | Vaccine Administration | Executing the wing-web vaccination technique on 5,800 hens. |
| Institutional | Inter-agency Synergy | Integrating academic research with field production. |
Why Field Training Matters for Public Health
From a medical perspective, the training of future veterinarians in the field is a frontline defense for human health. Many avian diseases have the potential to mutate or coexist with other pathogens that can cross the species barrier. By ensuring that the next generation of professionals can accurately identify and prevent diseases like avian pox, the region strengthens its overall biosecurity.
the interaction between producers like Facundo Costiuk and academic institutions ensures that the latest scientific research in poultry science is applied in real-time. This prevents the reliance on outdated practices and encourages the adoption of a “One Health” approach—the recognition that the health of people is closely connected to the health of animals and our shared environment.
The coordination seen in Campo Largo underscores the importance of the sanitary calendar. In poultry management, vaccination is not a one-time event but a continuous cycle of protection. By treating the vaccination process as a teaching moment, the community transforms a routine chore into a professional development milestone.

The ongoing collaboration between INTA and UNCAUS is expected to continue through the academic year, with further field rotations scheduled to monitor the health of the flocks and evaluate the long-term efficacy of the vaccination campaign in the Chaco region.
