Dear Partners, Industry Colleagues, Valued New and Existing Customers,

The new spring begins, and all things are renewed! Having celebrated a harmonious and happy Spring Festival, Shandong Efine Pharmaceutical Co., Ltd. has now officially sounded the clarion call for forging ahead in 2026. The company's production base, located at the Linyi Economic Development Zone, Dezhou City, Shandong Province, has completed comprehensive equipment maintenance and disinfection. All employees have returned to their posts with high spirits and full energy, marking the full resumption of work and production from today onwards. Normalized production and delivery of all orders have resumed.

2026 is a critical year for the deep transformation of the aquaculture industry towards green, efficient, and sustainable development. As a professional domestic supplier of aquatic feed attractants and anti-stress raw materials, we are always committed to helping farming partners meet the challenges of high-density aquaculture and improve feed efficiency through innovative functional additives. In the new year, we will focus our efforts on promoting the following four core products, providing customers with more competitive solutions.

2026 Main Promotional Core Product Matrix:

1.DMPT (Dimethyl-β-propiothetin) – The "Fast-Acting Feeding Signal"
As a fast-acting attractant recognized for its outstanding efficacy, our high-purity DMPT can strongly stimulate the olfactory and gustatory nerves of aquatic animals. Especially in feeds for special aquatic species like shrimp, snakehead fish, and California bass, it significantly shortens feeding time and reduces residual bait. It is an ideal choice to address decreased feed intake during periods of high temperature or disease.

2. DMT (Dimethylthetin) – The "Stable Growth Booster"
Aimed at pellet feeds and slow-sinking feeds that require long-lasting attractant effects, DMT offers better processing tolerance and dissolution stability in water. While increasing feed intake, it synergistically promotes the secretion of digestive enzymes, facilitating the full absorption and utilization of feed nutrients.

3. TMAO (Trimethylamine Oxide) – The "Osmotic Pressure Regulator" & "Debittering Agent"
Facing environmental changes in marine and freshwater aquaculture, TMAO effectively regulates the cellular osmotic pressure of fish and shrimp, reducing stress-related mortality caused by water changes or transport. Simultaneously, it significantly removes bitter tastes from feed, improving the flavor of fish meat, making it a secret weapon for creating high-end, quality aquatic products.

4. BETAINE (Compound Betaine) – The Classic "Nutrient Carrier"
As a methyl donor, our high-purity betaine not only aids in attracting feed but also effectively helps prevent fatty liver and promotes amino acid synthesis. In 2026, we are launching customized compound betaine, which can be used synergistically with DMPT/DMT to achieve the dual effects of "attractant + liver protection."

Sincerely Inviting Cooperation, Creating the Future Together

Starting work means taking action; the beginning is the sprint. Currently, our company has ample raw material inventory and all production lines are operating at full capacity. We can provide a full-chain service chain for feed enterprises, animal health companies, and aquaculture groups, including small-sample testing, pilot-scale production, and large-scale stable supply.

Whether you are seeking a cost-reduction solution to replace existing attractants, or hoping to create high-end feed with differentiated functions, Shandong Yifei Pharmaceutical Co., Ltd. will be a trustworthy partner for you.

In 2026, we look forward to joining hands with you:

• With the swiftness of DMPT, overcome feeding challenges;
• With the stability of DMT, enhance breeding efficiency;
• With the precision of TMAO, optimize aquatic product quality;
• With the purity of BETAINE, protect liver health.

We welcome calls and inquiries from new and old friends for samples or to discuss annual cooperation. Wishing you prosperous business. We look forward to your inquiry!
