Acidic Foundations Without Antibiotic Barriers: Techniques Usher in a New Chapter for Kawachi

—— nuacid’s First Vietnam Livestock Cost Reduction and Efficiency Enhancement Technology Summit

In late autumn, the humidity and heat in Hanoi gradually subside, and the sycamore leaves around Hoan Kiem Lake sway gently in the breeze. On this occasion, the innovation team of Guangdong nuacid Biotechnology Co., Ltd. … 2025 year 10 month 17 On [date], at the Long Bien Grand Hotel in Hanoi ( Long Bi ê n Palace ) Successfully held a sharing session on innovative solutions for reducing costs and increasing efficiency in feed and livestock farming. This conference brought together 40 A group of leading figures from Vietnam’s feed and livestock sectors gathered to focus on the current challenges facing the country’s animal husbandry industry—imminent restrictions on antibiotic use, heavy reliance on imported feed ingredients, frequent outbreaks of diseases such as African swine fever, and the rampant proliferation of pathogenic microorganisms in hot, humid conditions—and to explore in depth how technological innovation can help overcome these industry-wide obstacles.

At the meeting, Dr. Lin Decai, a swine husbandry technical expert from Thailand’s Charoen Pokphand Group, Mr. He Qiantai, an expert in acidifying technologies and processes, and nuacid… NIC Chief Scientist Researcher Hu Youjun, focusing on the three core themes of “Acid for Health, Acid to Reduce Costs, and Acid to Inhibit Viruses,” shared cutting-edge technologies and solutions for innovative approaches to lowering costs and improving efficiency in feed and livestock production.

Dr. Lin, a swine farming technology expert from Thailand’s Charoen Pokphand Group, traveled specially from Bangkok to share with everyone “ Acidifiers in the Healthy Breeding of Animals Application potential ” He mentioned that sourness is one of the five basic tastes, playing a role in regulating the gastrointestinal tract of humans and animals. pH play a role in the environment “ Core regulator ” The role of [the subject] directly influences digestion and absorption, immune defense, and intestinal homeostasis by precisely maintaining the acid–base balance across different segments of the gastrointestinal tract. Consequently, following the ban on antibiotic use in animal feed in the European Union and China, acidifying agents have been widely adopted in livestock and aquaculture feed.

As a global provider of acidifying agents, Guangdong nuacid Company focuses on the R&D, production, and sales of feed acidifiers. It has also introduced a three-dimensional acid-based healthy farming model encompassing acidic water, acidic feed, and an acidic environment. Based on this approach, nuacid NIC We have developed seven major acid families—preservative acids, digestive acids, intestinal acids, antiviral acids, antioxidant acids, environmental control acids, and liquid acids—to support healthy animal husbandry.

Dr. Lin also elaborated in detail on the acid‑based approach to promoting acid use, examining it from three perspectives: acidic water, acidic feed, and acidic environments, with specific products as examples. He explained that in animal husbandry, the first priority is ensuring drinking‑water health; therefore, acids should be added to drinking water to purify it. Secondly, when formulating feed, three key aspects must be addressed: first, to tackle digestive issues, we should use digestive acids to establish a solid digestive foundation in young animals; second, for intestinal health, we recommend using coated benzoic acid to effectively pass through the stomach and reach the intestines to inhibit harmful bacteria; third, to reduce susceptibility to viruses, we suggest employing antiviral compound medium‑chain fatty acids to lower viral loads in both feed and the animal’s body. Finally, we must also consider the rearing environment, where liquid acids can be used for environmental disinfection and to rapidly neutralize airborne… NH ₃、 CO ₂ Eliminate harmful gases and improve air quality in livestock housing.

In conclusion, Dr. Lin noted that, among the various types of feed additives, only acidifiers appear capable of addressing all of the aforementioned challenges at a cost acceptable to the livestock industry. He also expressed confidence that acidifiers will play an increasingly important role in promoting healthy animal husbandry in the future.

Mr. He Qiantai, an expert in acid technology and processes, gave a presentation to the Vietnamese guests in attendance. “ Comprehensive Liquid Addition Solution for Reducing Feed Costs and Improving Efficiency ” presented a report sharing insights on how to improve feed production and processing efficiency. The USDA Agricultural Office in Ho Chi Minh City noted that, as an agricultural powerhouse, Vietnam’s major feed‑crop industries—corn and soybeans—are hampered by issues related to germplasm resources and production efficiency. Domestic output has been declining year after year, leaving the country largely dependent on imports for soybeans and corn; for example, statistical data indicate that corn More than 78% Dependent on imports, while soybeans 95% The above are dependent on imports.

Therefore, improving feed processing efficiency and enhancing the utilization of nutrients such as energy and protein in feed—while integrating local by-products like bananas and coconuts—is an effective strategy for alleviating pressure from imported raw materials and rising prices, with liquid feed addition technology serving as a central component.

nuacid To address feed mills’ needs for cost reduction and efficiency gains, as well as to promote the utilization of local unconventional raw materials, we have jointly developed a comprehensive liquid‑additive solution with leading domestic equipment manufacturers. The system is characterized by high efficiency, precision, and ease of use, and has already been successfully deployed in China for the stable spray application of liquid methionine, liquid fermentation broth, liquid mold inhibitors, and liquid acidifiers.

Finally, expert He Qiantai demonstrated a feed-specific compound liquid acid preparation through examples. “ sour 5000” By incorporating schemes and real-world cases, it was found that employing a liquid acidifier addition protocol during feed processing can significantly optimize the entire feed production chain. This approach delivers six major benefits: enhancing starch gelatinization, markedly improving water retention, providing superior preservation, elevating feed processing quality (reducing fines content and increasing gloss), lowering production losses, and boosting animal performance. Finally, expert He Qiantai presented data-driven calculations demonstrating that this method can increase profit per ton of feed. 20-40 Yuan.

At this lecture tour, Researcher Hu Youjun—formerly a researcher at the Institute of Animal Science of the Guangdong Academy of Agricultural Sciences, Chief Scientist at the Innovation Center of Guangdong nuacid Company, and an off-campus graduate supervisor at Sichuan Agricultural University and South China Agricultural University—presented to the Vietnamese attendees new approaches to using acid preparations for virus control, reporting the in vivo and in vitro antiviral research results of Antiviral Acid (Tai Suan) in livestock and aquaculture species.

Researcher Hu Youjun proposed that animal husbandry health management must adhere to the “golden triangle” of antibacterial and antiviral strategies—biosecurity, vaccine immunization, and nutritional enhancement. Based on research data, he demonstrated that nutrition is the most critical component of this golden triangle. Medium-chain fatty acids offer excellent cost-effectiveness and possess direct antiviral activity, influencing viral activity in both feed and animal bodies; numerous studies in Europe, the United States, and China have confirmed their effects on PEDV Inhibitory effects against common livestock and poultry pathogens such as porcine epidemic diarrhea virus, blue ear virus, and Salmonella.

Based on the antibacterial and antiviral properties of medium-chain fatty acids, the Acid Innovation Center applies OAE Premium acid-effect technology and AEI Acid–electron interference technology, which screens specific medium-chain fatty acids and Lewis acids, has been used to develop a “feed‑borne antiviral acid formulation.” - Taisuan. This product can significantly inhibit the activity of common livestock and poultry viruses, block viral replication and proliferation, reduce viral loads in feed and animal bodies, and enhance feed and farming biosecurity.

Researcher Hu Youjun demonstrates on-site. 11 A case study from production practice demonstrates the antiviral efficacy of taurine: in collaboration with the virology research team at Sichuan Agricultural University. - Field trials conducted by Professor Xu Zhiwen’s team in collaboration with clients have shown that tiamulin is effective against the blue ear virus, PEDV , shows significant inhibitory effects on pseudorabies virus and others, and can enhance both in vivo and in vitro activity against PEDV 、 PRRSV The inhibition rate against porcine reproductive and respiratory syndrome virus; promotion of cytokine expression in the body, suppressing pro-inflammatory cytokines and enhancing anti-inflammatory cytokine secretion during field virus infection; enhancement of mucosal and microbial barrier functions in weaned piglets during the creep-feeding and nursery stages, thereby improving non-specific immunity and antiviral capacity; alleviation of PEDV 、 PRRSV It reduces pathologic damage caused by infection, lowers the incidence and mortality of viral diarrhea in piglets, and decreases viral injury to organs such as the lungs, spleen, kidneys, and brain. Relevant research findings have been published in 《 Frontiers In Veterinary Science 》《 Molecule 》and other authoritative journals.
