Which of the following feedstuffs does not contain phosphorous?
Answer Details
Limestone does not contain phosphorus.
Phosphorus is an essential mineral for animal growth and is typically found in many feedstuffs, including blood meal, fish meal, and oyster shell. However, limestone is primarily composed of calcium carbonate and does not contain significant amounts of phosphorus.
Limestone is often used as a source of calcium in animal diets, as calcium is another essential mineral for animal growth and development. In addition, limestone can also be used to adjust the pH of feed and drinking water to ensure that it is at an appropriate level for animals to digest and absorb nutrients effectively.
Therefore, out of the given options, limestone is the feedstuff that does not contain phosphorus.
