Abstract Eleven laboratories collaboratively studied the analysis of feeds for zinc, manganese, iron, and copper by atomic absorption spectrophotometry. Five feeds and one mineral mixture were analyzed. The feed samples were prepared by both dry ashing and wet digestion. Samples were analyzed chemically for manganese and iron. Results indicate the method is suitable for zinc, manganese, and iron. Further work is needed on the determination of copper. The method for atomic absorption analysis of feeds for calcium and magnesium (recommended too late for action in 1966) and the method for zinc, manganese, and iron are recommended for adoption as official, first action.
