From the Paper:

"The conclusions of this study state that the quantity of usable zinc is differential in casine-gelatin and soybean protein. When the chicks were fed nonfat milk, the growth rate of the chicks was slowed likely due to the imbalance of amino acid. The study notes that there was more availability of zinc in soybean meal than sesame meal believed to be due to the soluble factor present in soybean meal but not in sesame meals. Dried oysters caused too large of a weight gain and fishmeal zinc value is low accredited to be due to the presence of calcium in the fish meal with interferes with zinc absorption."
