Outside United States
You are asking a question about regional nutrient analysis. Each of these feed ingredients are considered protein supplements as they contain more than 20% crude protein (N x 6.25) as a component of dry matter. The amount of protein will range from approximately 60% (fish meal) to 25% for cotton oil cake. However many of these products are not commonly used in the United States so the databases of analysis are limited. You might look at feed analysis libraries for feed analysis laboratories here in the US. Two such labs that have online accessible feed composition libraries are Dairy One (www.dairyone.com) or Cumberland Valley Analytical Services (www.foragelab.com).
