NEW PROTEIN CHICK FEED BULLETIN OUT
WASHINGTON STATE COLLEGE, Pullman.—Information which will help poultrymen in Washington make a wiser selection of chick feeds having a high protein content is contained in a bulletin just released by the experiment station: at the State College of Washington. The efficiencies of Alaska herring fish meal, skim milk powder, high grade meat scrap, and Manchurian soybean meal were measured and compared in a study conducted by poultrymen and chemists at the college station and at the Western Washington experiment station at Puyallup.
Chick feeds popular in the Pacific Northwest were used and the amounts of protein, calcium and phosphorus were controlled by chemical analyses. Cockerels were removed from the flocks at from six to eight weeks of age so , that the final data includes only the 'pullets.
Comparisons were made between , chicks fed a straight ration of Alaska ! herring meal, and those fed the meal plus skim milk powder; between those fed soybean meal, fish meal, meat scrap, and other combinations of feeds.
It was found that the amount of protein needed by chicks steadily decreases until egg production commences, and raising the level of protein
only hastens maturity by a few days.
Copies of the bulletin, the Comparative efficiency of various Proteins for growing chicks, No. 321, may he secured by writing to E. C. Johnson, director, State College of Washington Experiment station, Pullman, Washington.
