[QUOTE="Ebenezer, post: 1798455, member: 24565"] "2. In block form. 3. Cheap and sufficient." What folks are trying to tell you is that blocks and assumed sufficiency are not parallels. And as most know, the form of mineral or vitamin has a huge impact on bioavailability. Then add in the issue of antagonists in the form of other minerals in the mix or in the forges. It is a complex issue but a proper mineral program is not just weaning weights but immune systems, hoof health, reproductions and so much more. I just read an abstract on a study that got postponed by USDA on various levels of iodine supplementation and subsequent tear concentrations to deal with pinkeye. It got sidelined due to covid but is interesting. And unless the footnotes tell differently, the units per day are for an AU of 1000 pounds so that a 1400 pound animal is 1.4 AUs to need 1.4X the recommended minimum. Continental breeds need more of some minerals than British breeds. I'd have to dig up notes to find the exact info. Not an exact science and totally soil and forage related. [/QUOTE]
