Iranian PhD Student Designs Automatic Respiratory Spray for Livestock
Azin Azizi, a final-year PhD student in veterinary medicine at Islamic Azad University’s Karaj branch, won a bronze medal at the 2025 World Inventors Competition in Geneva, Switzerland, with the idea of designing an automatic respiratory spray capable of delivering a specific dose of medicine and detecting hypoxia.
Azizi told ANA that the most effective recovery process in livestock was his goal for this invention, saying, “There is no foreign model that is completely similar to this product.”
She stated that the prototype of the design is a test sample.
In a relevant development in June, an Iranian veterinary PhD student had presented the idea of a bioshield to prevent the spread of viral, bacterial, and fungal pathogens in livestock and poultry.
“The idea of a bioshield is a surface nano-biological coating designed to prevent the entry and spread of viral, bacterial, and fungal pathogens in livestock and poultry,” Zahra Azadeh Ranjbar, a veterinary PhD student at the Islamic Azad University’s Shahr-e Kord branch, told ANA.
She explained that the coating uses zeolite nanoparticles impregnated with antiviral plant extracts (like thyme and garlic) and biopolymers like chitosan and can be used as a spray or bath and is applied to the skin or feathers without the need for injection, adding, “This layer remains for five to seven days and acts as a physical and chemical barrier, preventing the penetration of pathogens.”
“Rapid response to epidemic diseases like avian influenza, foot-and-mouth disease, brucellosis and Newcastle disease, immediate effect after use - unlike vaccines that require time -, suitable for times when vaccines are not yet available or complete immunity has not been formed, usability in farms, quarantine, livestock transportation, exhibitions and emergency situations, natural, antibiotic-free, without drug residues, safe even for sensitive animals and a complement to vaccination, usable without a cold chain or expert personnel are the advantages of the bioshield,” Azadeh Ranjbar said.
