The Utilization Of Food Elements By Growing Chicks. Iv. Meat Meal And Fish Meal Compared With Meat Meal, Fish Meal, And Soybean Meal As Protein Concentrates, C. W. Ackerson, M. J. Blish, F. E. Mussehl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. Two groups of 15 newly hatched chicks were fed rations differing in the composition of the protein concentrates. One lot received ration 2MFX, in which the concentrate was a mixture of meat meal and fish meal. In ration 3MFSX one-third of the meat and fish meals was replaced by soybean meal. The protein levels of the concentrates and of the rations as fed, were identical. 2. The composition of the chicks at the end of the feeding trial was determined, and the composition of the gains calculated. 3. The gain in live weight per gram of nitrogen or dry …

Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. The effects of adding to a basal ration, protein concentrates from animal and vegetable sources were studied by means of growth and body-analysis experiments. 2. There was a small increase in the nitrogen content of the chicks fed the animal protein concentrate, but no differences appeared between lots with respect to their content of calcium and phosphorus. 3. The percentage rate of gain and the gain per gram of nitrogen fed were greater in the lot fed the animal protein concentrate. 4. The lot fed the animal protein concentrate retained more of the nitrogen fed, but less of the …
Utilization Of Proteins By The Growing Chick, F. E. Mussehl, C. W. Ackerson
Utilization Of Proteins By The Growing Chick, F. E. Mussehl, C. W. Ackerson
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. There is a marked difference in the nutritive value of the various protein-contributing concentrates when used to supplement a corn-wheat basal ration which has been made complete for known vitamin and mineral essentials. 2. There is a great difference in the biological value even of animal protein concentrates. 3. Soybean meal produced a better growth rate than any of the other plant concentrates used. Cottonseed meal proved to have a greater growth-promoting value than did linseed oil meal. 4. The supplementing values of protein concentrates, one to another, is not quite as evident as one would expect if the …
