Industry application specifications and key points for purchasing
Feed regulatory agencies in various countries have listed lysine as a safe additive, allowing the addition of 0.5-3.5% in compound feed. When purchasing, you should focus on:
1. Hydrochloride or sulfate form with a purity of ≥98.5%
2. Meet the fluidity and stability standards of GB/T 12496-2019
3. The supplier has ISO22000 certified large-scale production capabilities
Formula design principles and precautions
Lysine requirements vary among different animal species:
1. The recommended addition amount for broiler feed is 1.2-1.8%
2. The suitable range for piglet feed is 1.0-1.5%
3. Aquatic feed needs to be used with methionine, and the ratio is maintained at 2:1
