Why these sources

Nutrilock Hydroxy Copper: Hydroxy source — low solubility in rumen, high absorption at the gut. NASEM 2021 lactating target; watch Mo/S antagonism.

Zinc Sulfate Monohydrate: Highly consistent commodity source, every lot assayed. Hoof integrity and SCC support.

Nutrilock SelenoSure: Uniform 2.1% dilution keeps blend CV under 4%. FDA regulatory max 0.3 ppm.

Manganese Sulfate (Chemlock): Third-party assayed against The Chemlock Standard. Reproduction and skeletal support.

Cobalt Carbonate (Chemlock): Micro-inclusion; premix carrier recommended. Rumen B12 synthesis.
