Feed your performance, your savings and your peace of mind


Feed your Performance. Rhodimet AT88 has an efficacy value of 100%. It has been scientifically tested through more than 25 trials, especially by Schothorst Feed Research (2014) and Bangkok Animal Research Center (2013). This value has also been shown by zootechnical results in large integrators for more than 20 years. This methionine source increases the flexibility of feed formulation processes, lowers feed costs and attenuates variations in animal production performance. Moreover, Rhodimet® AT88 is an organic acid with a pKa of 3.40 and an effective nutritional feed additive, which can improve broiler performance and poultry producer profitability in heat-stress conditions (Willemsen et al., 2001). In a nutshell, you will enjoy many benefits when formulating animal diets with Rhodimet® AT88.



Feed your Savings. Rhodimet® AT88 is the most economical source of methionine. It brings significant savings of up to 10% when you switch from DL-Methionine to DL-HMTBA. It reduces storage space requirements, simplifies incorporation, enables extensive automation and eliminates the need to recycle packaging. Finally, Rhodimet® AT88 improves the productivity of feedmills by reducing power consumption during feed pelletization.



Feed your Peace of Mind. Using Rhodimet® AT88 simplifies production processes and enables greater automation, while complying with good manufacturing, safety and industrial hygiene practices. It provides an elegant solution to the problems associated with handling additives in feed plants, particularly when it comes to unloading storage facilities, transferring the additives from place to place, weighing, batching and mixing. Moreover, several services proposed by Adisseo to complement Rhodimet® AT88 make it a safe, easy-to-use product: performing injections for better accuracy and homogeneity in feed, tailor-made dosing equipment, and nutrition guides, to name but a few. Adisseo offers Rhodimet® DiMension, a comprehensive service and support program, to ensure a seamless conversion from DL-Methionine to Rhodimet® AT88. With Adisseo’s liquid application system and engineering know-how, you can expect the same homogeneity in feeds as in DL-methionine. Finally, Adisseo gives you access to nutritional expertise as well as scientific and technical knowledge, so that you can achieve cost-effective feed formulations that make optimum use of Rhodimet® AT88.

Benefits of Rhodimet® AT88 for poultry

Methionine is the first limiting amino acid for protein synthesis in poultry. It should be provided in feed to ensure optimum poultry performance at a competitive cost.Various studies have clearly demonstrated that Rhodimet® AT88 is equivalent to other sources of methionine to promote poultry performance.

Benefits of Rhodimet® AT88 for swine

Underestimating the importance of methionine in pig nutrition can have a huge economic impact, and the choice of Rhodimet® AT88 as a source of methionine could benefit performance.After lysine and threonine, total sulfur amino acid (TSAA) requirements in pigs are the most important. They should be valued for effect on growth and production. Research also points to the beneficial effects of Rhodimet® AT88 on lactation, weaning stress and digestibility when provided “on-top” in the feed for lactating sows and suckling piglets.
