1. Three groups totaling 123 chicks were fed accurately known amounts of rations containing 0.9, 1.5, and 2.3 per cent of calcium with liberal provision of the antirachitic factor so that conditions for assimilation and deposition were favorable. 2. By means of the comparative slaughter test the retention of ingested nitrogen was found to be about 37 per cent, and that of phosphorus about 28 per cent in the three lots. 3. With 0.9 per cent calcium in the ration, 35 per cent of that ingested was retained; at a level of 1.5 per cent calcium, 24 per cent was …

The Effect Of Pregnancy And Parturition On The Weight Of Dairy Cows, R. F. Morgan, H. P. Davis
Nebraska Agricultural Experiment Station: Historical Research Bulletins
A study was made of the effect of pregnancy and parturition upon the weight cycle of dairy cows of the Ayrshire, Guernsey, Holstein, and Jersey breeds according to gestation periods from data accumulated from records for the period 1922 to 1934 of the dairy herd of the Dairy Husbandry Department of the University of Nebraska. The weights of the cows were obtained from three consecutive weighings made at the middle of each month and daily weighings beginning at the 265th day of pregnancy and continuing for 30 days after calving. A total of 656 separate gestation periods were tabulated according …

1. The nitrogen, calcium, and phosphorus content of 127 newly hatched chicks was determined. 2. Thirty newly hatched chicks were fed accurately known amounts of a good chick mash for 60 days. At the end of the period nitrogen, calcium, phosphorus, and fat were determined for each chick. 3. By means of the comparative slaughter test the retention of nitrogen was found to be 37.8 per cent, calcium 43.4 per cent, and phosphorus 27.3 per cent of the respective elements fed. 4. The average gain in live weight per gram of nitrogen fed was 12.0 grams. 5. The rate of …

Determining The Sex Of Day Old Chicks, H. E. Alder
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.

Notes On The Owls Found In Lincoln County, Nebraska, Wilson Tout
Notes On The Owls Found In Lincoln County, Nebraska, Wilson Tout
Papers in Ornithology
During more than a quarter of a century I have been making notes and collecting information about the Owls of Lincoln county and it seemed an opportune time to put this information into print that it might be available to those who are interested in birds and serve as a basis for further study and amplification. Lincoln County is not usually considered a favorable place for Owls to reside on account of the absence of heavy timber over most of its area. But the nine varieties listed will probably be extended as more observations are made by those who are …

The Vitamin E Content Of Certain Dairy Feeds, I. L. Hathaway, H. P. Davis
The Vitamin E Content Of Certain Dairy Feeds, I. L. Hathaway, H. P. Davis
Nebraska Agricultural Experiment Station: Historical Research Bulletins
A study was made of the vitamin E content of each of the ingredients of our dairy herd ration, excepting the salt, lime, and bone meal. Female rats which were able to conceive but unable to reproduce when fed a diet deficient in vitamin E were fed the various feeds as a source of vitamin E during a second breeding period. The presence of vitamin E in a feed was thus shown by the ability of the female to cast a litter. The vitamin E content of bran, shorts, linseed oil meal, hominy feed, white corn, yellow corn, cottonseed meal, …

Some Observations On Humidity And Weight Loss In The Incubation Of Turkey Eggs, F. E. Mussehl, C. W. Ackerson
Nebraska Agricultural Experiment Station: Historical Research Bulletins
1. Turkey eggs which are incubated under chicken hens lose from 11 to 13 per cent of their original weight during the first 24 days of incubation. Small turkey eggs lose relatively more weight than large eggs incubated under the same conditions. 2. Considerable variation was observed in the weight loss during the first 24 days of incubation of eggs of approximately the same size when incubated in the same environment. The range was from 7 to 24 per cent of the original weight. Differences in shell texture may account for these variations, although care was taken to select only …

Some Digenetic Trematodes From Deep-Water Fish Of Tortugas, Florida, Harold W. Manter
Some Digenetic Trematodes From Deep-Water Fish Of Tortugas, Florida, Harold W. Manter
Harold W. Manter Laboratory of Parasitology: Library Materials
Introduction (first two paragraphs)
The parasitic fauna of ocean depths is practically unknown. Although an extensive fish population occurs at all depths, very little study has yet been made on the helminths of these fish. During the summers of 1930, 1931, and 1932 excellent opportunity was offered for the collection of parasites from fish trawled from depths varying from 40 to 582 fathoms at Tortugas, Florida. A considerable number of systematic hauls by the staff and crew of the Tortugas Biological Laboratory of the Carnegie Institution of Washington yielded an abundance and considerable variety of fish, some of rare forms, …

The Vitamin A Content Of Skimmilk, Standardized Milk, And Cream From Different Breeds Of Cows, I. L. Hathaway, H. P. Davis
Nebraska Agricultural Experiment Station: Historical Research Bulletins
A study was made of the vitamin A content of skimmilk, of milk standardized by the addition of separated milk, and of cream. Rats whose body stores of vitamin A had been depleted by being fed a vitamin A deficient ration were fed either skimmilk, standardized milk, or cream as a source of vitamin A. Approximately 750 rats were used in nine experiments. From the results of these experiments the following conclusions were drawn: (1) that the vitamin A content of milk is associated largely with the butterfat and that separated milk containing a small quantity of fat contains only …

Why Some Hens Lay More Eggs Than Others, H. E. Alder
Why Some Hens Lay More Eggs Than Others, H. E. Alder
Nebraska Agricultural Experiment Station: Historical Circulars
The 1929 report of the Storrs Egg Laying Contest, which has been conducted at Storrs, Connecticut, twenty-one years, shows that the best pen of ten hens entered laid 2,802 eggs, and the poorest pen laid 829 eggs. In the best pen the average egg production per hen was 280, 2 eggs as compared with 82.9 eggs per bird in the poorest pen. Why did the one pen lay so many eggs, and the other so few? This prompts us to try to find out what factors are responsible for the number of eggs a hen lays in the course of …

The Vitamin A And The Vitamin E Content Of Field-Cured And Artificially Cured Alfalfa Hay, I. L. Hathaway, H. P. Davis, R. R. Graves
Nebraska Agricultural Experiment Station: Historical Research Bulletins
A comparative study of the vitamin A content of field-cured and artificially cured alfalfa was made by comparing the growth produced by 124 rats receiving alfalfa hay as their source of vitamin A. From the results of this study, in which the experiments were duplicated, it is concluded that under the conditions of these experiments the artificially cured alfalfa was twice as potent in vitamin A as was the field-cured alfalfa. The comparative study of the vitamin E content of these hays was made by comparing the number of litters produced by groups of female rats which received graded quantities …
