Supplements for Cottonseed Meal in Diets for Chickens

Abstract

CONSIDERABLE information has been obtained on the dietary deficiencies of soybean meal as a source of protein for chickens, and on supplements that can be included in diets along with soybean meal as sources of its deficient nutrients, but little is known about cottonseed meal. At least two of the few available reports indicate that the same feedstuffs can be used in diets along with either cottonseed meal or soybean meal as sources of nutrients in which they are deficient.Heywang (1947) reported that 15 percent cottonseed meal and 15 percent soybean meal were of about equal value when they were supplemented by small quantities of either sardine meal or meat scraps in diets for laying chickens. Bird and coworkers (1948) found that both cottonseed meal and soybean meal are deficient in a dietary factor essential for the growth of chickens, and found in cow manure and fish meal.That .
