Abstract
- L-Aspartic acid does not seem useful as a protein surrogate in conventionally formulated low-protein diets for broiler chicks. 2. Urea as a protein substitute does not enhance the value of conventional broiler diets. 3. Urea does not improve broiler diets that have been supplemented with fish meal or crystalline amino acids to satisfy requirements for all indispensable amino acids. 4. Urea is absorbed into the bloodstream, but is not assimilated into body proteins.
摘要
- 在传统配制的肉鸡低蛋白日粮中，L-天冬氨酸似乎不能作为蛋白质替代物。2. 尿素作为蛋白质替代物并不能提高传统肉鸡日粮的价值。3. 对于已添加鱼粉或结晶氨基酸以满足所有必需氨基酸需求的肉鸡日粮，尿素并无改善作用。4. 尿素可被吸收进入血液，但不会被同化为体蛋白。
