Relation Of Height At Withers And Chest Girth To Live Weight Of Dairy Cattle Of Different Breeds And Ages, H. P. Davis, R. F. Morgan, Samuel Brody, A. C. Ragsdale

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The size of a dairy cow is important from the standpoint of feed consumption and economy of production and also as an indication of the expected size of offspring. The ultimate disposal of dairy cattle is for beef, and the measure of returns is based upon size and condition. A method for the determination of the approximate weights of dairy females, where scales are not available, is needed. Measurements of dairy cattle which show development and skeletal growth by ages in relationship to weight are presented here for four different dairy breeds.

Judging Quality In Dairy Products, P. A. Downs

Nebraska Agricultural Experiment Station: Historical Circulars

In the dairy industry increasing attention is being paid to the question of quality of products. The well established system of buying and selling butter and cheese on the basis of quality by score or grade is practiced in the principal markets of the world. The other dairy products, while not marketed by score, are receiving more and more attention in this respect. As more information becomes available and the judging better standardized, other dairy products will doubtless be sold by grade.

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 …

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, …

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 …

White Scours Of Calves, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

It becomes possible to understand some of the reasons for the occurrence of disorders among the newborn of animals kept under the usual conditions imposed by domestication. Among these, the subject of this circular, White Scours in Calves, occupies a prominent place.

The Influence Of Feed And Sunshine On The Vitamin D Content Of Cow’S Milk, Ben L. Robinson

Electronic Theses and Dissertations

For the past several years there has been a growing tendency among dairymen, particularity those located near the large cities, to keep their cows in the barn much of the time. Under such a system of management the cows receive but little direct sunshine. In some localities it is also possible to find many cows which are fed the year around on dry feed receiving very little, if any, green food, either as soiling crops or as pasture. From many standpoints such practices are, of course, necessary and desirable, but from the standpoint of the nutritional value of the milk …

The Influence Of Number Of Daily Milkings On The Production Of Dairy Cows, R. F. Morgan, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

High-producing Holstein, Jersey, Ayrshire, and Guernsey cows of various ages milked three times daily produced from 39.69 to 52.26 per cent more fat and from 44.98 to 65.18 per cent more milk than cows milked twice daily. When high-producing cows of all breeds milked four times daily were compared with cows milked twice daily, the fat production for the several age classes varied from 110.19 to 127.53 per cent and the milk production from 149.08 to 160.31 per cent greater for those milked four times. Milking high-producing cows four times as compared with three times daily showed an increased fat …

The Vitamin A Content Of The Milk Of Holstein, Ayrshire, Jersey, And Guernsey Cows, H. P. Davis, I. L. Hathaway

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A comparative study of the vitamin A content of milk produced by Holstein, Ayrshire, Jersey, and Guernsey cows was made by comparing the growth produced by 560 rats receiving milk from these breeds as their only source of vitamin A. The results showed some slight irregular differences in the gains produced by the milk from the different breeds. When these differences were considered in view of the individual variation of the experimental animals, they appeared negligible. This conclusion was substantiated by a statistical examination of the data. From the results of this study in which the experiments were duplicated, it …

Economic Aspects Of Contagious Abortion In A Dairy Herd, Department Of Animal Husbandry

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of this study is to present the measurable losses due to abortion in a dairy herd of high-producing ability over a period of approximately one-third of a century. The records available provide a rather complete history of what has taken place.

A Study Of Bull Associations, Arthur J. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

"A cooperative bull association", according to the United States Department of Agri culture, is "a farmers' organization formed for the purpose of joint ownership, use, and exchange of high class, purebred dairy bulls."

The members of the association are divided into three or more groups of neighboring farmers, each group being known as a block. A block may consist of one herd or several herds and contains from 40 to 60 cows. One bull is used in each block, and in order to prevent inbreeding, each bull is moved to another block every two years. If all the bulls live …

Babcock Testing - Principles And Uses, L. K. Crowe, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

The manufacturing of dairy products on a commercial scale began about the middle of the nineteenth century and was greatly stimulated by the development of the centrifugal cream separator in the late eighties. The invention of the Babcock test in the early nineties overcame some of the difficulties that had developed in paying for milk upon its butterfat content, since it was early recognized that milk varied widely in that respect.

The Evaluation Of The Dairy Cow, George Gardner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The accurate appraisal of property is in a great many cases a difficult task. A savings account in a bank may be evaluated with high precision. A business building in a large city may bring in returns sufficiently steady and permanent so that a careful appraiser with a reasonable knowledge of depreciation losses to be anticipated might fix a value without very much error.

Selection, Breeding, Methods Means More Milk, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Milk good cows. It pays if you know how. Good dairy cows will always make money. Scrub, poor, or common cows never bring a good profit and usually cause a loss. Why waste feed and labor on inefficient producers, the kind that never make a satisfactory profit? Join a cow testing association. Let the tester keep books on your cows and let the milk scale and the milk sheet point out the money makers. Improvement comes only from selection and breeding.

Feeding The Dairy Cow, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Cows produce milk from feed and water only. Therefore feed in proper quantity and quality is usually the limiting factor governing a cow's production up to the limit of her capacity.

Dairy Calf Care And Management, H. P. Davis, R. F. Morgan

Nebraska Agricultural Experiment Station: Historical Circulars

Calf raising begins before the calf is born. A cow that is healthy and in good physical condition will, in all probability, drop a strong, vigorous calf. The feeding and care of the cow before calving is therefore of the greatest importance for the future development of the calf.

Better Sires -- Better Stock: Build Better By Breeding, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Economy and logic indicate that the most satisfactory method of obtaining higher-yielding dairy cattle is to breed them. Nebraska raises the feeds - corn, oats and alfalfa - that will grow dairy cattle and can raise them as cheaply as any region. The method is simple. Use purebred dairy sires on the present cows. By the use of good purebred dairy sires great improvement can be obtained in a single generation.

A Study Of The Effect Of The Age Of Parents On The Ability Of Dairy Cows To Produce Milk And Butterfat, J. Howard Maughan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The question of the possible effect of the age of parents on the quality of the offspring which they produce has long been a disputed one. It is held by some that the ages of both parents act together in determining the quality of offspring. There are others who maintain that the age of the dam only is a factor and still others who believe that only the age of the sire need be considered in this connection.

Bovine Tuberculosis, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

Tuberculosis affects all species of domestic mammals although with different degrees of intensity and frequency. Cattle and swine furnish the greatest number of cases.

Dairy Barn And Milk House Arrangement, J. H. Frandsen, W. B. Nevens

Nebraska Agricultural Experiment Station: Historical Circulars

From an economic point of view, as well as from the standpoint of animal comfort, it is highly desirable that adequate barn or shed facilities be provided for the dairy herd. Some farmers have developed the idea that to keep cows healthy and comfortable and to produce sanitary milk it is absolutely necessary to have expensive barns. As a matter of fact, many of the dairy barns where sanitation is the primary object are quite inexpensive. On the other hand, if the barn is conveniently arranged and made to embody the most accepted sanitary features, it is very essential that …

Purebred Sires Effect Herd Improvement, M. N. Lawritson, J. W. Hendrickson, W. B. Nevens

Nebraska Agricultural Experiment Station: Historical Circulars

The real worth of a sire for the dairy herd can be established only when production records of the progeny are available for comparison with those of the preceding generation. A study of the following three sires which have been in service in the University of Nebraska dairy herd should be of interest to the Nebraska dairyman wishing to improve his own herd. This experiment indicates that the apparently high cost of a good herd sire is more than outweighed by the increase in the value of the progeny.

Cooling Tanks And Milk Houses As Factors In Cream Improvement, J. H. Frandsen

Nebraska Agricultural Experiment Station: Historical Circulars

The dairymen of this country have suffered enormous losses due to the lower price received for poor butter. The present need is for a survey of the situation that shall result in a thoro understanding and cooperation of cream producers, creamery men, legislators, and educators.

Bulletin No. 127 - Report Of The Richmond-Lewiston Cow Testing Association, W. E. Carroll

UAES Bulletins

The function of all domestic animals is to utilize the coarse rough reeds and transform them into something useful to mankind, either food, clothing, or energy. The animal thus acts as a concentrator for low grade ores, so to speak. The class of animals which will produce most human food, clothing, or energy for man from a given amount of feel--other cost being equal--is the most economical and the one which will remain longest with us as population becomes more dense and the question of food supply becomes keener.

Experiments have shown the dairy cow to be probably the most …

Bulletin No. 96 - Care Of Milk On The Farm And The Manufacture Of Butter And Cheese, R. W. Clark

UAES Bulletins

Dairying is one of the most profitable lines of agriculture in Utah. Ever since the establishment of the dairy industry in the State, the demand for Utah butter and cheese has been strong and prices have averaged good. A good article will always sell at top price; a poor article may sell at a good price when the demand is strong, but it will not sell at a good price, if at all, when the demand is weak. High prices are undesirable at any time if they create a tendency to put out a poor article. The success of any …

Bulletin No. 57 - By-Products Of The Dairy, F. B. Linfield

UAES Bulletins

Soon after becoming connected with the Station, the writer, from observations made in various parts of the State, was impressed with the necessity for investigation looking to the profitable disposal of the by-products of the dairy, both at the factory and on the farm. The common method at the factories seemed to be to feed hogs on milk or whey alone, and where grain was fed, it was only given to finish the hog for market. This method of management did not appear to be successful, for it generally took the whole season to get one crop of hogs ready …

Bulletin No. 43 - 1. Dairy Herd Record For 1984-95. 2. Winter Feeding Experiments With Dairy Cows. 3. Some Suggestions On The Building And Equipment Of Factories., F. B. Linfield

UAES Bulletins

The Dairy Department of this Station was fully organized by June 1894. The latter part of 1893 and early part of 1894 were devoted to fitting up the dairy rooms and getting the' necessary appliances and machinery in place. As our dairy herd was too small for experimental work, it was decided during the spring of 1894 to increase the number to fifteen head. The selection and purchasing of those cows were left to the writer.

Bulletin No. 42 - Creaming Experiments, F. B. Linfield

UAES Bulletins

During the summer of 1894, before our hand separator was fitted with power attachment, the writer found it scarcely practicable to run the separator, so that most of the milk was skimmed by deep setting. Although the usual methods of procedure were practiced, it was found impossible to get results that were satisfactory, or that would approximately compare with those reported from many eastern stations. Because of this and because ' the larger proportion of our dairymen use some method of setting, it was decided to undertake a series of experiments that might throw some light upon the subject. As …
