The Utilization Of Food Elements By Growing Chicks. V. A Comparison Of Cottonseed Meal And Linseed Oil Meal As Portions Of The Protein Concentrate, C. W. Ackerson, M. J. Blish, F. E. Mussehl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. Two lots of newly hatched chicks were fed rations differing only in five per cent of their make-up. In the ration of one lot five parts of linseed oil meal were added to 95 parts of the base, and in the other ration a mixture of 4.5 parts of cottonseed meal and 0.5 part of starch was added, to keep the protein level the same. The remaining portions of the two concentrates were made up of five parts each of meat scraps and fish meal. 2. The amounts of feed consumed by all chicks of both lots were kept …

Determining The Sex Of Day-Old Chicks, H. E. Alder
Nebraska Agricultural Experiment Station: Historical Circulars
More than 2,000 years ago people were interested in determining the sex of the embryo in hatching eggs and the sex of day-old chicks. No method of determining the sex of day-old chicks (except of course in sex-linked chicks) was of the slightest value until the Japanese method was discovered and developed. About 1925 Japanese scientists discovered the presence of a rudimentary copulatory organ located on the ventral rim of the cloaca which was present in all day-old males and only a few day-old females.
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
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 …
