Have been using plain mineral blocks for over a decade and put them on stumps. I know, oh the horror of a simple, cheap, cattle block. Have heard and read about how terrible a simple, cheap meant for cattle block is. But our deer use them pretty much daily from March to November. Are they as good as getting the perfect mixture of minerals, not a chance. But they are simple, cheap and work great for what I want them for, tcam observation. Minerals haven’t really been proven scientifically to do anything for antler growth through a long term research study. We all know they probably help with overall health to some degree, which over time if done regularly boost health, but genetics, geographical location, hunting pressure, management and regulations probably play a way bigger role. The hype to spend a lot of money on flavored, over priced salt is idiotic. To use a formulated bagged mineral mixture is far better than anything bought with a picture of a buck on it in a retail store.
Watched the video and all be it interesting, there wasn’t a lot of meat or protein there for guys who already fart around with management, be it plots, supplemental feeding, management practices or mineral supplementation.
