The Influence of Protein Source on the Response of Chicks to Corn Oil ,

A HIGHLY significant response in chick growth to soybean oil has been shown by Campbell and Hill (1962) when diets contained either soybean protein, fish flour, egg albumen or blood fibrin as sources of protein. The following study was conducted in our laboratory in an effort to relate the growth response of chicks to corn oil to the lipid content of 3 different dietary proteins and to the fatty acid content of the chicks’ liver. Soybean protein, casein-gelatin, and heated egg albumen were used as protein sources. The soybean protein was used as prepared commercially and after extraction in our laboratory with hot methanol. Day-old Athens-Canadian Randombred male chicks were randomly allotted into pens of 12 each. Two pens were allotted to each of 8 diet treatments. The chicks were housed in electrically heated battery brooders and maintained for 4 weeks with ad libitum feeding. The treatments consisted of…
