Frequently Asked Questions
It boosts nutrient absorption by enhancing glutathione (GSH) synthesis in the intestinal mucosa, leading to an 8.5% increase in average daily gain (ADG).
Yes, 0.05% cysteine can replace approximately 0.03% methionine equivalent, potentially saving ¥80-120 per ton of formula cost.
The active sulfhydryl (-SH) groups of L-Cysteine directly bind to AFB1 epoxides, reducing liver residues by up to 55%.
Yes, it is listed in EU No 68/2013 (Reg. No. E920) and approved for use in all animal life stages.
It serves as a sulfur source for methionine, promoting the calcification matrix and increasing shell thickness by 8-12μm.
Avoid direct mixing with strong oxidizers, such as Copper Sulfate (CuSO₄), to maintain the stability of the sulfhydryl groups.
