Talcum powder is made from a soft mineral called hydrous magnesium silicate that is found throughout the world. It is crushed, dried and milled to produce powder used in cosmetic products by millions of people.
The rumen and reticulum (reticulo-rumen) is the largest compartment of the cowâs stomach. Fiber, starch, sugar, and proteins are fermented by the microbes to form volatile fatty acids and microbial protein. Rumen papillae absorb volatile fatty acids.
The interior surface of the rumen forms numerous papillae. The papillae can be long and foliated or short and pointed. They are up to 6mm in length. Animals fed on rough grass or in the dry season have longer papillae, whereas animals fed on digestible feed or in the wet season have shorter papillae (1-2mm in length).
