[QUOTE="Lucky_P, post: 1011986, member: 12607"] The 'red' trace-mineralized salt blocks rarely contain enough Copper or Selenium to be regarded as any sort of a significant mineral supplement - particularly if you're located in an area where soil levels of Cu or Se are low - or if there are 'competing' minerals, like S, Fe, Mo, etc. present in the soil or other feeds. Those red salt blocks actually contain iron oxide as a coloring agent/filler - and even though FeO cannot be absorbed, it can block copper-absorption sites in the intestine, and may actually make copper deficiency worse than if you weren't supplementing at all. I tell folks that if they're not going to feed a good balanced loose mineral (or, I guess a complete mineral block), that they're better off just putting out white salt blocks, and not bothering with the red trace-mineralized salt blocks.
