Students create deodorizing products for livestock farming

From practical lessons at the Faculty of Agriculture and Forestry, Quang Nam College, and his concern about the bad smell in barns in his hometown, student Vo Dinh Thi researched and successfully created a product to eliminate bad odors in livestock farming using microorganisms.

Since returning to her hometown to help her family take care of the pigs, the strong, damp smell in the barn made Thi think a lot about the surrounding living environment and the health of the animals.

With the knowledge learned at school, Thi began to research microbial preparations, experimenting with natural fermentation using easily available ingredients such as rice bran, yeast, and water. The first batches failed, but after many notes and adjustments, Thi gradually came up with a suitable formula.

Initial results show that just 1kg of the product spread on 10m2 of livestock barn floor significantly reduces odor, creates a more airy environment, and reduces the risk of respiratory diseases in livestock. For chicken coops, the product is mixed with rice husks as bedding, both to limit odor and to reduce the risk of disease spread.

Some households that have used the product say that it not only improves the environment of their barns, but also reduces the incidence of African swine fever. Although there has not been comprehensive scientific verification, the product has proven to be effective, creating trust among users.

The special feature of this product is its versatility. In addition to treating odors, the product has also been tested to compost food, supplement beneficial microorganisms for the intestines, help keep pets healthy, and significantly reduce veterinary drug costs.

Compared to expensive commercial products, Thi's products have the advantage of being much cheaper, easy to use, and suitable for small-scale farming households. From an initial capital of only 5 million VND to buy tools and materials, after a few months of testing, Thi has proven that the product is feasible and can be replicated.

MSc. Nguyen Thi My Linh, lecturer of the Faculty of Agriculture and Forestry, who directly guided the project on producing deodorizing products for livestock farming, shared: “I and many lecturers in the faculty highly appreciate Thi's initiative and enthusiasm. The product has been tested for quality and tested in many different livestock farming models to ensure practicality. The initial results are positive. If further improved, this will be a useful product, helping farmers reduce environmental burden and save costs.”

At the 7th National Student Startup Festival held in Ho Chi Minh City in April 2025, the project to produce deodorizing products for livestock farming won third prize in the category of students of vocational training institutions in the fields of agriculture, forestry and fisheries. This is the motivation for Thi to bring the product to consumers in the future, after optimizing the product.

“My bigger goal is to improve the fermentation process, enhance quality, and register a trademark so that the product has a long-term position in the market,” Thi said.
