Zeweier: Leading the high-quality development of the feed additive industry with chelation technology
As the global feed additive market continues to expand, China, as a major livestock industry country, has a growing demand for efficient and safe trace elements. Since its establishment in 1995, Nanning Zeweier Feed Co., Ltd. (hereinafter referred to as "Zewil") has always taken "defending chelated purity" as its mission, and has become a benchmark enterprise for high-quality development in the industry by relying on technological innovation and standard setting. Recently, Zhou Jianqun, chairman of Zeweier, was interviewed by reporters, revealing how Zeweier corporate philosophy of "strong, upright, pure and refined" has promoted China's animal husbandry to move towards a green and safe direction.

Technology-based Enterprise: Innovative Practice to Fill Industry Gaps
As the only company in Guangxi that has obtained a chelate production license from the Ministry of Agriculture and Rural Affairs, Zeweier core competitiveness stems from its independently developed organic trace element technology. The company's pioneering oligosaccharide chelated zinc and chelated iron technology not only fills the gap in the domestic feed additive field, but also wins industry attention with its world-leading sucrose chelate technology. Chairman Zhou Jianqun said: "Our annual R&D investment accounts for more than 4% of sales. Through industry-university-research cooperation, we have built a full-chain innovation system from theory to production."
Products with high purity and high chelation rate as the core features have significantly improved the absorption efficiency of trace elements by animals. For example, the chelation rate of Zeweier chelated zinc products is as high as 98%, which is much higher than the 30%-40% of traditional inorganic zinc. While reducing the amount of addition, it also reduces the risk of environmental pollution. This breakthrough technology provides new ideas for the sustainable development of animal husbandry.
Standards first: leading the standardized development of the industry
Zewil is not only a practitioner of technological innovation, but also a setter of industry standards. The company took the lead in drafting the national standards for "Feed Additive Ferrous Fumarate" and "Feed Additive Calcium Citrate", among which the calcium citrate standard became the first batch of mandatory national standards in China. Zhou Jianqun emphasized: "Standards are the cornerstone of high-quality development of the industry. We hope to promote the entire industry from disorderly competition to quality priority through standardization."
From farm to table: building a healthy food industry chain
Zewil's vision is not limited to the field of feed additives. In the future, the company plans to focus on high-purity organic trace elements and extend to the upstream and downstream of the food industry chain, from the source of the farm to the consumer's table, to ensure food safety and nutrition throughout the process. Chairman Zhou Jianqun said: "Our goal is to allow every Chinese to enjoy healthy and safe food."
