Buyer: LactaPrime, a high-end dairy feed group based in Madrid, Spain. It is a leading organic lactation feed R&D enterprise in the Iberian Peninsula, supplying organic pastures across Spain and high-end infant milk source supporting pastures in the EU. It specializes in high-end antibiotic-free, low-nitrogen emission TMR total mixed rations, complying with EU Regulation 2002/32 on feed, EFSA nutritional standards and feed additive access specifications issued by the Spanish Ministry of Agriculture. The group purchases 52 tons of pharmaceutical-grade coated rumen-protected methionine annually and has long adopted coated methionine imported from Adisseo France. To cut raw material costs, it purchased domestic customized rumen-protected methionine in bulk, yet four major production and formula technical failures emerged during operation on the client’s fully automatic feed pelleting and total mixing production line: severe coating breakage during feed pelleting, unbalanced dietary amino acid ratios, substandard milk protein after pasture feeding, and caking and mildew of finished products, pushing feed scrap rate above 32% and delaying the launch plan of its new organic ration. Domestic suppliers only mastered raw material production and lacked familiarity with European dietary formula systems and pelleting processes, unable to conduct two-way troubleshooting from both raw material and terminal formula perspectives. The client entrusted HiSiaddi Foreign Trade’s technical team to deliver full-chain technical optimization and rectification.
Domestic raw materials adopted conventional high-temperature vegetable oil coating. The client’s pelleting section operated at 82~88°C, causing coating melting and shedding. Methionine was decomposed by microorganisms in the rumen, reducing small intestinal effective absorption rate from the target 65% to 29%. Milk protein failed to rise and even declined after pasture feeding. Root Cause: The melting point of the original coating oil was not matched to European high-temperature pelleting working conditions, as production only followed domestic low-temperature normal mixing standards.
Trace residual free methionine by-products in raw materials underwent acid-base reactions with calcium carbonate, calcium phosphorus mineral salts in the formula, leading to caking and rancidity after 30 days of finished product storage, reduced palatability and lower dairy cow feed intake. Root Cause: The product refining section lacked multi-stage water washing impurity removal procedures; impurity indicators only met national standards and failed to satisfy high-end EU dietary compatibility requirements.
Raw materials featured a wide range of coarse and fine particles with fine powder proportion exceeding 7%. Stratification occurred after mixing in the client’s automatic TMR premixer, resulting in excessive methionine in partial positions and insufficient methionine in others within the same batch of feed, failing Spanish feed nutrition uniformity sampling inspection standards.
The client retained the addition coefficient of French imported raw materials for formula design. The domestic raw materials had lower baseline rumen bypass rate, leading to overall insufficient methionine in rations under fixed addition ratios, unbalanced amino acid proportions and non-compliance with NRC lactating cow nutrition matching specifications.
1. Coating Formula Technical Renovation: Coordinated the factory to replace oil with low-melting-point hydrogenated plant palm oil, adjusted coating content to 17.5%±0.8%, and optimized low-temperature spray coating process. Finished products withstand short-term pelleting high temperature of 90°C, with post-pelleting rumen bypass retention rate stably ≥63%.
2. Refining and Impurity Removal Optimization: Added three-stage countercurrent pure water washing and secondary recrystallization procedures to strictly control free acidic impurities and eliminate subsequent compatibility acid-base reactions at source.
3. Particle Grading Modification: Installed double-layer precision air flow screening equipment to lock particle size within the 0.35~0.6mm range and control fine powder proportion ≤1.1%, completely resolving material mixing stratification.
1. Combining the measured bioavailability of modified domestic methionine, HiSiaddi’s technical team revised the original formula matching ratio, adjusted the dietary lysine:methionine ratio to the industry optimal standard of 3:1, reduced dietary soybean meal addition by 3.2% and lowered dietary crude protein to align with EU low-nitrogen emission reduction policies.
2. Added 0.18% food-grade hydrophobic silica as anti-caking agent into formulas to buffer acid-base reactions and improve feed storage stability.
1. Segmented temperature control in pelleting section: Reduce conditioning temperature by 5~6°C in the front section and adopt short-term high-temperature forming in the rear section to shorten raw material heating duration and reduce coating breakage.
2. Revised feeding sequence: Adopt stepwise premixing process – premix methionine with trace premix at low speed for 10 minutes first, then add bulk raw materials for full mixing to improve material mixing uniformity.
1. Accelerated storage test in laboratory: Optimized feed showed no caking or rancidity after 90 days of storage at constant 40°C.
2. Small-scale pasture feeding trial: Selected two benchmark organic pastures for small-batch feeding over 28 days. Milk protein increased by 0.19% and nitrogen excretion decreased by 16.3%, with all indicators meeting the client’s internal control standards.
3. Finalized mass production standards and issued English full-item COAs and in-vitro rumen bypass test reports recognized by Spanish authorities.
1. Spanish LactaPrime Group: Successfully completed domestic substitution of imported raw materials with overall procurement costs reduced by 31.5%. High-end organic rations were officially launched across all high-end pastures in Spain. New procurement orders were added from pastures in Portugal and Greece within half a year, expanding annual purchase volume from the original 52 tons to 68 tons.
2. Domestic Raw Material Manufacturers: Solidified the production process for high-temperature-resistant coating high-end grades of rumen-protected methionine. The export premium of the products was 39% higher than ordinary feed-grade methionine. Leveraging the benchmark client qualification in Spain, successive sample cooperation was developed with high-end feed brands in Italy and Ireland.
3. HiSiaddi Foreign Trade: Established an integrated amino acid technical service system covering "raw material process improvement + terminal dietary formula adjustment + downstream production line process optimization". Subsequent supporting methionine technical projects were delivered for multiple mid-to-high-end agriculture and animal husbandry enterprises in Germany and Finland.
Most domestic methionine manufacturers focus on mass production of general feed-grade products, with coating and refining processes designed around conventional domestic feed working conditions, lacking understanding of high-temperature pelleting and precise formula systems adopted by high-end European feed manufacturers. High-end European dairy enterprises feature rigorous dietary formulas and strict regulatory requirements; minor deviations in raw material indicators will trigger production failures and ineffective feeding. Relying on professional feed amino acid technology, HiSiaddi synchronously addresses technical pain points through two-way rectification of upstream factory processes and downstream terminal formula optimization, assisting overseas mid-to-high-end clients in achieving smooth domestic substitution of raw materials.
