Animal feed supplement for livestock is chelated by DL-methionine and zinc sulphate 1. Resulting from the reaction of a mole of zinc ion to a moles of methionine, high chelate percentage ,the greatest stability. 2. High bioavailability , better nutrition of zinc,is a kind of better feed additive 3. Don't be affected by pH value, inorganic ions and organic macromolecules in digestive tract. Higher utilization ratio [Product function] 1. The bioavailability of animal feed supplement for livestock significantly better than other organic zinc. 2.

Increase feed intake effectively , can improve animal growth and the resistance of disease.promote more nutrition 6.This zinc methionine can suplement animals nore nutrition healthy,can make the animals growth Specification of DL-Methionine: Items Specification(AJI92) Appearance White crystals or crystalline powder Assay(%) 99.0%~101.0% Heavy metal(Pb%) =0.002 Transmittance(%) =98.0 PH 5.6~6.1 Loss on drying(%) =0.3 Residue on ignition(%) =0.1 Chloride(Cl%) =0.02 Sulfate(SO4%) =0.02 Iron(Fe%) =0.001 Arsenic(As2O3%) =0.0001 Ammonium(NH4%) =0.02 Package:25kg Bag Or as requirement Usage: DL-Methionine is one of the basic units for composing the protein, is the only sulfur bearing amino acid among the essential amino acids, it participated in the transmethylation interior the animal body, the phosphorus metabolism and the adrenalin, choline and creatine synthesis, it also is the raw material of the protein and cystine synthesis. Methionine is unable to synthesize in the animal body, must take in from food. Adds it in the feed, can promote the poultry to grow, increase lean meat quantity and reduce the feeding cycle. 1, Service we can provide: 1.
