Special Co-organizer of the 2025 Heguang Forum | Guangdong nuacid Biotechnology Co., Ltd. invites you to join this grand event!

Securing the supply of pig feed ensures national stability, and the swine industry is vital to both the economy and people’s livelihoods. However, piglet mortality accounts for a significant share of losses in pig production; statistics show that piglet deaths comprise 50%–70% of total mortality in this sector. Diarrhea is the leading cause of piglet deaths, with nutritional diarrhea emerging as a critical bottleneck issue in the post‑antibiotic era.
To overcome the current challenges in the swine industry—high litter sizes accompanied by high rates of weak piglets and mortality—the theme of the 14th Lactating and Weaned Pig Nutrition and Health Conference has been further elevated for 2025. From May 16–18, 2025, the conference will bring together leading academic experts and practical technical specialists from the feed sector ahead of the Qingdao Animal Husbandry Expo. Centered on the theme “From Weaning Power to Growth Power,” the event will explore key industry issues—from a nutritional perspective—including lactating and weaned pig nutrition, post‑weaning diarrhea, rearing and management practices, and creep feed formulation. By thoroughly addressing the dietary and nutritional needs of piglets across different production stages, the conference aims to support optimal growth from weaning through finishing, helping farms enhance productivity. It seeks to establish an integrated platform for exchanging knowledge and insights into the development of the lactating and weaned pig sector, thereby accelerating the creation of new, high‑quality productive forces within China’s swine industry.

Acid can uphold the acid‑use philosophy of “acid first for antibiotic‑free feed, acid at the core of healthy farming,” remain value‑driven, and collaborate closely with customers. It has successfully launched a “Comprehensive Acidification System Solution” and established a complete portfolio of acid formulations covering four key feed‑and‑farming dimensions—digestion promotion, antibacterial action, antiviral protection, and antioxidant activity—including preservative acids, digestive acids, intestinal acids, antiviral acids, antioxidant acids, environmental‑control acids, and drinking‑water acids.
Through collaborative research with leading academic and research institutions—including the Institute of Animal Nutrition at Sichuan Agricultural University, the Subtropical Ecology Institute of the Chinese Academy of Sciences, and Jiangxi Agricultural University—nuacid has identified the optimal formulation ratio between benzoic acid and multiple functional ingredients. This resulted in the development of a next-generation controlled-release benzoic acid product, AiSuanLing 9001. Not only does it enhance controlled-release technology for benzoic acid molecules within the intestinal tract, ensuring effective antibacterial action throughout the gut for 6–12 hours, but its additive, synergistic, and permeation-enhancing effects with various functional components further reduce the required application dosage. As a result, AiSuanLing 9001 has become the preferred choice for piglet intestinal health management, delivering superior efficacy and cost-effectiveness in reducing diarrhea and promoting growth. With just 1 kg of AiSuanLing 9001 added per ton of feed, it can fully revolutionize intestinal health outcomes in the industry.
Improved controlled-release performance: By upgrading the delivery system and controlled-release technology and formulating it with fumaric acid, the product can safely pass through the stomach; after reaching the duodenum, the sustained-release matrix gradually disintegrates to release the active ingredient, which is then steadily delivered to different regions of the intestine over 6–12 hours.
Higher molecular retention rate: An optimized permeabilizer facilitates the accelerated uptake of molecular benzoic acid into pathogenic bacterial cells, thereby preventing ionization caused by the high intestinal pH that would otherwise neutralize the released benzoic acid.
Improved antibacterial performance: Permeabilization enhances both the penetration ability and quantity of molecular benzoic acid, resulting in a more pronounced antibacterial effect. Test results from NIC Microbiology Laboratory and an independent third-party testing organization show that Aisuanling 9001 inhibits Salmonella at 1000 ppm and achieves complete inhibition at 1500 ppm; it inhibits Escherichia coli and Staphylococcus aureus at 1500 ppm and achieves complete inhibition at 1800 ppm. Its performance is significantly superior to comparable products on the market.
Intestinal Acid Preparation – Aixinling 9001 has achieved a leap in proven energy efficiency: Made in China, 1 kilogram is effective.
How effective is Aisuanling 9001 in practical applications? Joint experiments conducted by the Acid Innovation Center with several leading academic institutions—including the Institute of Animal Nutrition at Sichuan Agricultural University, the Subtropical Ecology Institute of the Chinese Academy of Sciences, and Jiangxi Agricultural University—have demonstrated that:
Degree of dissociation of Aisuanling 9001 in aqueous solution: After dissolving in water, the pH of Aisuanling 9001 gradually decreases over time. Results show that after 4 hours, the pH of the aqueous solution has decreased by only 0.27, indicating that Aisuanling 9001 exhibits a low degree of dissociation and can remain in molecular form for an extended period, thereby conferring long-lasting antibacterial activity.
Aisuanling 9001 artificially simulates gastric controlled-release effects: In artificial gastric fluid, after 1 hour, the retention rate of Aisuanling 9001 was as high as 74.7%, and after 2 hours, it still retained 69.3%. In contrast, the retention rate of benzoic acid raw powder was only 21.6% after 1 hour and extremely low after 2 hours.
Aisuanling 9001 exhibits artificial intestinal-simulated controlled-release performance: In artificial intestinal fluid, benzoic acid powder was completely released by 1 hour; by 4 hours, the retention rate of Aisuanling 9001 had decreased gradually from 70.1% at 1 hour to 49.1%, and by 5 hours it had further declined to 32.5%. By 6 hours, the retention rate of Aisuanling 9001 had dropped to 10.5%, indicating that sustained antibacterial activity can be achieved in the distal intestine.
Application trial of Aisuanling 9001 in animal production: Experimental results obtained at the nuacid Innovation Center’s animal research facility and in piglets raised by a Guangdong-based group demonstrate that adding just 1 kg of Aisuanling 9001 per ton of feed significantly reduces diarrhea and improves intestinal health, with efficacy surpassing that of using 3 kg of pure benzoic acid.
Enhancing the molecular retention rate of benzoic acid in the intestinal tract is key to its precise and efficient application. Through collaborative research with leading academic and research institutions—including the Institute of Animal Nutrition at Sichuan Agricultural University, the Subtropical Ecology Institute of the Chinese Academy of Sciences, and Jiangxi Agricultural University—AcidNeng nuacid has identified the optimal formulation of benzoic acid combined with multiple functional ingredients. This resulted in the development of a next-generation controlled-release benzoic acid product, Aisuanling 9001. This product not only advances controlled-release technology for benzoic acid molecules within the animal gut, ensuring effective antibacterial action throughout the entire intestinal tract, but also leverages additive, synergistic, and permeation-enhancing effects with various functional components to further reduce the required dosage. As a result, it has become the preferred intestinal antibacterial agent for weaned piglets, promoting growth while reducing diarrhea, delivering “Made in China” innovation that achieves remarkable efficacy at just 1 kg per ton—a true industry breakthrough.
