【Product performance】:
DL-Methionine Feed Grade is approved for use in all animal species. Particularly used in monogastric, it ensures an adequate supply of sulfur amino acids, especially of the essential methionine. Additionally, diets for piglets and growing pigs can show a considerable deficiency in methionine, especially when formulated to achieve low nitrogen excretion for ecological reasons. Increasing the utilization of feed resources decreases the cost of feed. Such a deficiency can be conveniently compensated by using Feed Grade DL-Methionine.

FAQ
Q1: What is the difference between DL-methionine and L-methionine?
A1: DL-methionine and L-methionine are two different forms of methionine. The difference mainly lies in their structure and biological activity.
Structure: L-methionine is a left-handed form of methionine, the form naturally found in organisms. DL-methionine is synthesized from L-methionine and contains both left- and right-handed configurations, that is, a mixture.
Bioactivity: Since L-methionine is in its natural form, it has higher bioavailability and bioactivity to organisms. In contrast, DL-methionine has low biological activity, and its right-handed configuration usually has no obvious impact on the physiological functions of animals.
Q2: Can the addition of DL-methionine improve the feed utilization of animals?
A2: Yes, the addition of DL-methionine can improve the feed utilization of animals, but this depends on the combined influence of multiple factors.
Protein Synthesis: Methionine is an essential amino acid that is essential for protein synthesis. By providing an appropriate amount of DL-methionine, methionine that may be insufficient in animal feed can be supplemented, thereby promoting protein synthesis.
Feed formulation: The addition of DL-methionine needs to be considered in conjunction with a comprehensive feed formulation. Properly proportioned feed can maximize the role of DL-methionine and improve feed utilization.
Animal breeds and growth stages: Different animal breeds and growth stages have different requirements for DL-methionine. Therefore, feed formulations need to be adjusted on a case-by-case basis to ensure optimal utilization of DL-methionine.
