The production of bone powder is not suitable for domestic workshop because the processing of fresh bones requires innocuous, timely sterilization production in certain scale. The workshop processing only relies on sun curing, no automatic temperature control and sterilizing installations, low in production cost but vulnerable to cross contamination and serious in noxious germ count. So, it is not suitable for feedstuff manufacturers to use it.
