Spring in Full Bloom at Southeast Flower City

Guangdong nuacid can assist the Fujian Provincial Feed Industry Association. 2025 The Annual Feed Conference Concluded Successfully

Though the bitter winter has arrived, a wave of enthusiasm is surging. 2025 year 12 month 18 On [date], the Southeast Flower Expo Garden in Zhangzhou, Fujian, was packed with distinguished guests and vibrant intellectual exchange—“ 2025 The “High-Quality Development Conference for Fujian’s Feed Industry” has been grandly inaugurated here. The conference is guided by the China Feed Industry Association, hosted by the Fujian Provincial Feed Industry Association, and organized by the Zhangzhou City Feed Industry Association. It receives title sponsorship from Fujian Haixin Group Co., Ltd., as well as friendly collaboration from feed associations in more than twenty provinces and cities nationwide. The conference is themed “Empowering with New Quality.” With “green development” at its core, the event brought together policymakers, academic authorities, industry leaders, and front-line experts to jointly explore pathways for high-quality development of China’s feed industry—particularly in the southeastern region—within the multifaceted context of the post-antibiotic era, carbon neutrality goals, and industrial upgrading.

The conference opened amid a solemn yet enthusiastic atmosphere. Lu Yonglin, Executive Deputy Secretary-General of the China Feed Industry Association, delivered a keynote address titled “China’s Feed and Livestock Market: Current Situation and Future Prospects.” Secretary-General Lu systematically analyzed the resource constraints, environmental pressures, and challenges posed by upgrading consumer preferences currently facing the feed industry. She noted that over the past four decades, China’s feed industry has achieved leapfrog development, with total output increasing from less than 50 Increased from ten thousand tons to 3.15 hundred million tons, strongly supporting the vigorous development of the aquaculture industry. However, the industry currently faces severe challenges: feed grain consumption now accounts for of the nation’s total grain consumption. 53.6% , the industry exhibits a high dependence on imported raw materials; it simultaneously faces “double pressure” from volatile raw material costs and weak downstream demand, resulting in pronounced market differentiation and continued increases in industry concentration ( CR8 Has reached 36.0% ), small and medium-sized enterprises are under significant pressure.

Although 2024 Total annual feed production declined slightly year on year, with the mix continuing to adjust dynamically; pig feed growth remained steady but slowed, while emerging segments such as pet food posted strong gains. Facing this new phase, Secretary-General Lu called on the industry to remain confident, embrace change, and work together to steer the sector toward a high-quality, sustainable future.

Guangdong nuacid Biotechnology Co., Ltd. was invited to participate as a special co-organizer, NIC Researcher Hu Youjun, the chief scientist, delivered a presentation titled “Regulation of Intestinal Microecological Balance in Piglets in an Antibiotic-Free Environment” at the conference.

Acid can NIC Researcher Hu Youjun began by noting that, as the ban on antibiotic growth promoters has entered a normalized phase, the industry’s challenges have evolved from the initial focus on “finding alternatives” to addressing how to systematically maintain intestinal health and stability in animals, particularly weaned piglets. As the core site of nutrient digestion and absorption, a barrier for immune defense, and a hub for microbial ecological balance, intestinal health directly determines the success or failure of livestock production.

Appropriate gastrointestinal tract pH Like for acid - bacteria - An enzyme-tailored “survival code”: it provides a stable environment for probiotic fermentation and acid production, allowing “Sour” Its regulatory function is precisely exerted; it builds a safe environment for beneficial bacteria. “Fertile ground for survival,” it inhibits harmful bacteria from occupying ecological niches, ensuring microbial balance; it also activates the catalytic activity of digestive enzymes, enabling efficient breakdown. The three work together under suitable conditions… pH Under its influence, a positive feedback loop is established: substances such as short-chain fatty acids produced by probiotic fermentation further fine-tune the gut. pH , and stable pH It also enhances enzyme activity, aiding the breakdown of nutrients, which in turn provides energy for microbial growth, ultimately achieving a dynamic balance for gut health.

Key data reveal a stark reality: the ratio of bacteria to human somatic cells in the human gut is approximately 1:1 Different, in pigs this ratio is as high as 30:1 This means that the complexity and importance of the porcine intestinal microbiome far exceed our previous understanding. Weaning stress and insufficient gastric acid secretion (within one month after weaning, nearly half of piglets experience gastric... pH>4 ), protein digestibility drops sharply (in the early post-weaning period, it can fall below 40% ) and other issues are intertwined, leading to “digestive disorders” - Abnormal fermentation in the hindgut - Microbiota imbalance - The vicious cycle of intestinal damage. Consistent with the health‑focused acid‑use philosophy that nuacid has long emphasized—namely, “acidic water, acidic environment, acidic feed”—Researcher Hu Youjun specifically pointed out that the latest edition of “Swine Diseases” … 12 The edition has listed feed acidification and drinking water acidification as one of the five key ecological measures for controlling Escherichia coli infections, marking international recognition of “acid” as a cornerstone in the antibiotic‑free era.

Researcher Hu Youjun guided everyone to move beyond conventional nutritional thinking and focus on an emerging concept—indigestible protein in the distal ileum ( IIDP ）。Undigested protein in feed enters the large intestine, where microbial fermentation produces harmful substances such as ammonia and amines, directly damaging the intestinal mucosa, triggering inflammation, and disrupting the balance of the gut microbiota. Data indicate that the protein digestibility in weaned piglets may remain lower than expected over the long term, particularly during the pre-weaning phase. 2 The weekly protein digestibility is lower than 40% This means a higher proportion of protein becomes “terminal redundant protein,” providing ample substrate for fermentation by harmful bacteria in the hindgut. To address this issue, we must tackle it at the source—by enhancing gastric digestion. The physiological deficiency of adequate gastric acid secretion must be compensated for with exogenous acidifiers.

Based on the above analysis, Teacher Hu proposed a “three-in-one” precision regulation strategy centered on acidifiers.

1.  Front-end Enhanced Digestion: Laying a Solid Foundation for Health

Remedy physiological gastric acid deficiency, and the stomach pH Drop to 3.5 Next, activate pepsin. Choose an efficient compound acidifier. Research shows that different acid sources vary significantly in their effectiveness at reducing buffer capacity and enhancing digestion, so selection should be precise based on the diet’s composition. Improving the digestibility of dietary protein in the anterior gut to fundamentally reduce substrates for harmful fermentation in the hindgut is Lowest cost, highest efficiency Health interventions.

Feed acidifying capacity is a key factor influencing the effectiveness of acidification, and different raw materials, diet formulations, and animal stages result in markedly varying requirements for acidifiers. In the past, the selection of acidifiers largely relied on experience, with a lack of scientifically quantitative tools.

Based on a deep understanding of the industry’s key challenges, Guangdong nuacid Biotechnology Co., Ltd. spent 5 In [year], we continuously collected and analyzed extensive data on feed ingredient buffering capacity, acidifier characteristics, and animal trial results, thereby establishing an industry-leading acidification database. Building on this foundation, we successfully developed and launched “...” Digestive Acid Selection Model APP ” This tool can comprehensively consider feed formulation, raw material types, cost constraints, animal stage, and objectives. pH By considering multiple variables, we provide customers with precise and efficient acidizing agent selection and dosage solutions, enabling a transition from “experience-based acidizing” to “scientific acidizing.” Currently, this model’s 1.0 The version has been officially released and put into use, offering greater intelligence and precision. 2.0 The release of the version is imminent, marking a solid step forward for nuacid in the field of digital tools for precision nutrition.

2.  Backend Targeted Antibacterial Action: Patented Encapsulation Technology for Benzoic Acid

Researcher Hu Youjun provides an in-depth analysis of “star acid,” benzoic acid. Its advantages include a broad antibacterial spectrum, low propensity for resistance development, and relative friendliness toward beneficial bacteria such as lactic acid bacteria. However, a major challenge with its traditional applications is that, under the neutral conditions of the intestinal environment, the retention rate of the molecular form is extremely low, necessitating high-dose supplementation ( 5-10kg/t ) can only take effect in the hindgut, potentially affecting palatability and metabolic burden.

The breakthrough solution for benzoic acid—encapsulation and controlled-release technology: Using patented encapsulation, benzoic acid is protected from stomach acidity and released precisely in the distal intestine (ileum and colon). Fistula experiments demonstrate that the concentration of encapsulated benzoic acid in the distal intestine is higher than that of the unencapsulated product. 5-7 times.

In field trials, 1.5 kg/t Benzoic acid coating can be substituted. 5kg/t Regular benzoic acid, and achieve an additional increase in daily weight gain 3-5% , significantly reducing the incidence of diarrhea. It effectively improves intestinal villus morphology, enhances the expression of tight junction proteins, and repairs the physical barrier. Encapsulation technology upgrades benzoic acid from a conventional “stomach-acid‑supplement‑centric” approach to a true “gut‑targeted antibacterial agent,” achieving a balance of efficacy, precision, and cost‑effectiveness.

3.  Extending the Defensive Front: Exploring the Antiviral Potential of Medium-Chain Fatty Acids

Facing the threat of viral diarrhea, Teacher Hu shared new frontiers in nutritional interventions. Research indicates that certain medium-chain fatty acids and their monoglycerides (particularly C8、C10 ) can effectively inactivate enveloped viruses (such as PEDV 、 PRRSV ) of the lipid envelope.

Molecular simulation screening: Computational models can be used to efficiently screen for acid molecules with antiviral potential. Challenge studies show that specific combinations of medium-chain fatty acids can significantly reduce enterovirus loads and increase immunoglobulin levels ( IgG 、 IgA ) levels, alleviate inflammatory responses, restore the intestinal barrier, and promote the rebalancing of dysbiotic microbiota. This provides new tools and approaches to shift feed formulations from “nutritional support” to “nutritional defense.”

4.  The Puzzle of the Future: Focusing on Emerging Concepts Such as “Amino Prebiotics”

Finally, Professor Hu forward‑lookingly identified other key components for future modulation of the gut microbiota, particularly the concept of “amino prebiotics.” With the trend toward low‑protein diets, certain non‑essential amino acids or small peptides may serve as specialized nutrients for beneficial gut bacteria or directly participate in immune regulation. Paying attention to these novel functional substances will make intestinal health strategies more comprehensive and holistic.

This presentation was not merely a sharing of technology, but also an upgrade in thinking. It clearly demonstrated that, in the post-antibiotic era, victory will belong to companies that deeply understand animal physiological nuances and can intelligently regulate through precise technologies and systematic solutions. Through this conference, Guangdong nuacid Biotechnology once again highlighted its profound dedication and leading role in the field of acid nutrition science, injecting solid technological momentum into the industry’s high-quality development. At Guangdong nuacid Bio’s exhibition booth ( 2A006 ) Before that, industry peers kept coming for consultations and exchanges, which is the best testament to its cutting-edge concepts and solid technology.

In Zhangzhou at year’s end, the fervor of ideas dispels the winter chill. This in-depth exploration centered on “acidity” serves as a key, opening the door to a new world of “precision nutrition and healthy aquaculture.” It signals that innovation in China’s feed industry is shifting from broad conceptual advocacy to a deeper focus on mechanistic insights and precise application technologies. Along this path, companies like Guangdong nuacid, backed by steadfast research commitment and keen industry insight, are leading the sector into deeper, more expansive blue oceans.
