Protein Zinc Feed Additive — Crude Protein 20%, Zinc 10%–20% | High Bioavailability Organic Trace Mineral
Protein Zinc Feed Additive — Crude Protein 20%, Zinc 10%–20% | High Bioavailability Organic Trace Mineral
Product Overview
Protein Zinc is a premium organic trace mineral feed additive produced through advanced enzymatic chelation technology. By binding zinc ions to plant-derived small peptides, this product achieves a high chelation rate and superior bioavailability compared to traditional inorganic zinc sources such as zinc sulfate or zinc oxide.
With a crude protein content of ≥ 20% and zinc content of 10%–20%, this additive is widely used in swine, poultry, ruminant, and aquatic feed formulations. It supports growth performance, immune function, reproductive health, and skin/hoof integrity — while reducing environmental excretion of excess minerals.

Key Benefits
1. Higher Absorption Rate
The small-peptide chelate structure protects zinc from antagonism by calcium, iron, and phytates in the digestive tract. Zinc is absorbed via peptide transport pathways, resulting in significantly higher bioavailability than inorganic zinc salts.
2. Stable & Compatible
The chelated structure remains stable during feed processing and storage. It does not catalyze the oxidation of vitamins or fats, helping preserve the nutritional value of premixes and complete feed.
3. Supports Growth & Immunity
Zinc is essential for enzyme activation, protein synthesis, and immune cell function. Adequate organic zinc supplementation promotes feed intake, daily gain, and disease resistance.
4. Improves Skin, Hoof & Feather Condition
Helps prevent parakeratosis in pigs, hoof cracking in cattle, and feather pecking in poultry. Also supports wound healing and epithelial tissue integrity.
5. Reproductive Support
Plays a key role in hormone synthesis and reproductive organ development, improving conception rate and offspring vitality in breeding stock.
6. Environmentally Friendly
Lower inclusion rates and higher retention mean less zinc excreted into manure and water, supporting sustainable farming and environmental compliance.
