Protein Feeds for the War Period

The shortage of high-protein feeds and protein supplements for livestock is becoming more acute every day. Supplies of animal protein are not large enough to meet present needs mainly because of the increased demand for them due to (1) greater use of protein feeds by livestock producers in order to provide more milk, meat, and eggs, and (2) the need for larger amounts of casein and other animal proteins, as well as certain vegetable proteins, in war industries. It has been estimated that the shortage of protein concentrates in the United States will exceed 1,810,000 tons for 1943.\u27 Because of this shortage it is very important to the war effort that every livestock producer-farmer, rancher, and livestock feeder-do everything within his power to use existing supplies efficiently and to produce more protein feeds. He can use them best by avoiding overfeeding and other waste of feed, culling out low-producing animals and selling them, and using methods approved by authorities to control diseases and maintain sanitation
