Forty Years Of Dairy Cattle Breeding At The North Platte Experiment Station, Mogens Plum, Myron G.A. Rumery

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In 1913 the Nebraska Legislature appropriated $17,500 to establish a Dairy Department at the North Platte Experiment Station. The department's herd was to be used in demonstrating management and breeding practices and as a source of breeding stock. Since the North Platte herd was started, research in the field of animal breeding has developed new concepts in many phases of dairy cattle breeding and selection. The purpose of the present study is to analyze the progress made under a system of dairy cattle breeding and selection carried out according to the principles that dominated 40 years ago. The results of …

Comparative Measurements Of Holstein, Ayrshire, Guernsey, And Jersey Females From Birth To Seven Years, H. P. Davis, I. L. Hathaway

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Body measurements are important for a proper understanding of how growth takes place in animals. Unfortunately, few growth data other than for weight have been published concerning dairy cattle. This is a report of measurements of females in the University of Nebraska dairy herd made as part of a long-time growth study. During the period 1922 to 1942 each animal born into the herd was weighed and measured at regular intervals. Presented here are the data for weight, height, length, width, depth, girth and hide thickness for females of the Holstein, Ayrshire, Guernsey, and Jersey breeds. The average body measurements …

Growth Measurements Of Holstein Females From Birth To Seven Years, H. P. Davis, I. L. Hathaway

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Measurements of growth, to be meaningful, must be taken of various parts of the body, at regular intervals, under standardized environmental conditions, from birth through the growth span of the animal. From these measurements skeletal growth standards may be prepared for the several ages. Such standards can be used to measure growth at any age period. They will serve the research worker as a guide for experimental procedure and will provide the livestock raiser a basis with which his animals may be compared. Present standards of growth for dairy cattle are based mostly upon live weight, although considerable data are …

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 Use Of Lactic Acid In The Manufacture Of Cheddar Cheese From Milk Containing An Antibiotic, Elmer George Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The manufacture of cheddar cheese is greatly dependent on bacterial growth for acid production. The quality of cheese depends upon the type and extent of microbial activity.

An important function of the lactic fermenting bacteria is the production of acid resulting from cellular metabolism. If little or no acid is production of acid resulting from cellular metabolism. If little or no acid is produced the resulting cheese will have an inferior body, flavor, and texture and may even cause the cheese to be used as grinders.

Effects On Urinary Metabolites Of Rats Fed Various Edible Fats, Cleve R. Winkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years, substitutes for butterfat have been the subject of much controversy. Their acceptance as being nutritionally equal to butterfat has often been question. The importance of this problem lies primarily in its economic and nutritional significance.

A recent study of public attitudes toward dairy products conducted by Alfred Politz Research, Inc. for the American Dairy Association, shows that 48.4 per cent of the population believed that butter is a more nutritions food than oleomargarine. Only 6 per cent thought that oleomargarine is more nutritious while 27.2 per cent believed they are about the same. The remainder, 18.4 per …

Lactation Curves Of Holstein Cows As Influenced By Age, Gestation, And Season Of Freshening, George Edward Patterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lactation curves of dairy cows have been studied by dairy scientists for many years. The effects of various hereditary end non-hereditary influences on the lactation curve have been observed. Factors have been developed to standardize production to a common basis, correcting for differences in age, length of lactation, milking per day, gestation and environment.

Use Of Corn Syrup Solids Of Different Dextrose Equivalents In The Manufacture Of Frozen Desserts, Wiggo F. Axelgard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ice cream industry continually faces the problem of improving its frozen desserts. At the present time corn syrup solids are being used to supplement milk serum solids to improve the body and texture of these products.

One of the problems is to increase the total solids content of frozen desserts without increasing sweetness or developing sandiness in the finished product. There is a limit to the amount of milk serum solids that can be used because of the danger of sandiness and the cost. The use of corn syrup solids helps to overcome these limiting factors.

The corn syrup …

Rearing Calves On Ten Gallons Of Milk, L C. Snook

Journal of the Department of Agriculture, Western Australia, Series 3

Only a limited number of calves are reared on dairy farms which sell whole milk. At current prices, it is only a very good calf which is worth more than the milk it would consume, and as a result, the heifer calves from thousands of productive cows are each year slaughtered at birth. In the past the whole milk supplier was able to obtain his herd replacements from farmers in the more distant dairying districts who, of necessity sold butterfat and could rear calves on separated milk.

Layout Of A Dairy Premise, A E. Baker

Journal of the Department of Agriculture, Western Australia, Series 3

As the average dairyman spends a large proportion of his working time in the milking shed throughout the year, careful attention to the layout of these premises will give good returns in time saved, and will enable the task of milking to be carried out efficiently and with a minimum of discomfort.

The Influence Of Amounts Of Propionibacterium Shermanii On Eye Formation And Flavor Of Swiss Cheese, Dan G. Turner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Swiss cheese has been rightly called "king of the cheeses." It has been prized the world over for its stately appearance and sweet "hazelnut" flavor. In grading Swiss cheese, these two things,appearance and flavor, are important considerations in determining the cheese score. Appearance is judges according to the number, type, and size of eyes present in the cheese, with color and body and texture also considered. Flavor is judges according to the degree of sweetness and the amount and kinds of off flavors present.

In the past, there has been considerable variation in the quality of the Swiss cheese produces. …

A Comparison Of Formulae In The Manufacture Of Ice Milk, Glen Wilford Sargent

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ice milk is not a new product in the ice cream industry. Rather it is one that has gained only little popularity, except in the preparation of "malts" and "milk shakes"; however, within the last decade the gallonage of ice milk produced has more than doubled.

Ice milk has been relatively unimportant because of the difficulty of obtaining a product with acceptable quality. In recent years progressive ice milk manufacturers and research workers have discovered new ingredients and processing procedure that seem to produce favorable results.

This low-fat product has several merits that justify its recent popularity, such as low …

A Note On Chronic Footrot Of Dairy Cattle

Journal of the Department of Agriculture, Western Australia, Series 3

With the advent of treatment with ™ sodium sulphamezathine for footrot of dairy cattle, many of the troubles associated with this condition have largely been overcome.

However, the importance of early treatment is sometimes overlooked and Fig. 1.—Chronic footrot caused the ragged growth of new bone shown in the two lower pictures. At the top are the bones of a healthy foot from an animal of similar size. some farmers are inclined to blame the drug when treatment has been commenced after the animal has been affected for some time and a cure does not result. Why treatment is not …

The Shorthorns, J A. Mallett

Journal of the Department of Agriculture, Western Australia, Series 3

Among "The Stud Farm of the World" the red, white and roan Shorthorns have always been given pride of place in the cattle section. They were the first of the popular cattle breeds existing today to be systematically improved, and at the present time approximately three-quarters of all the cattle in the British Isles carry a preponderance of Shorthorn blood.

Growth And Respiratory Studies Of Saccaromyces Cerevisiae In The Presence Of Selenium, Robert M. Pengra

Electronic Theses and Dissertations

The occurrence of selenium in certain soils of the United States and its detrimental effect upon livestock pastured on or fed forage from these areas has been well established. Selenium poisoning will not be reviewed here as several excellent reviews have been published (1, 2, 3). Studies on the metabolism of selenium by Sac-charomyces cerevisiae have been reported by Potter and Elvehjem (4), Lardy and Moxon (5), and Fels and Cheldelin (6, 7, 8). An attempt has been made in this thesis to repeat and enlarge on some of these studies. While this investigation may contribute information on the selenium …

An Open Letter To Dairyfarmers, H P. Schapper

Journal of the Department of Agriculture, Western Australia, Series 3

As dairyfarmers, you are part of one of Australia's major industries—an industry which, according to the 1947 Census employed 106,526 persons in dairyfarming alone. As dairyfarmers, you contributed to the 1,200 millions of gallons of milk produced last year which incidentally was worth something like £80,000,000 net at the farm gate. Viewed from the nutritional standpoint, you are even more important. You contributed to the supplies of butter, milk and milk products which on a per head per day basis were the source of 21% of the total calories, 16.4% total protein, 44.6% total fat, 76.5% total calcium, 49.5% vitamin …

Disease Of Dairy Cattle - Warts And Eye Cancer, J Craig

Journal of the Department of Agriculture, Western Australia, Series 3

Papilloma or warts are by no means uncommon in dairy cattle in Western Australia. In maturing cows, they usually occur on the udder, while in young stock they may be found on the head, neck, and shoulders. In bad cases, a large proportion of the body area may be covered with the warts, forming large cauliflower- like masses which often bleed easily.

Better Dairying Competition 1951-1952, H G. Elliott

Journal of the Department of Agriculture, Western Australia, Series 3

The success of the Better Dairying Competitions in previous years prompted the Western Australian Pasture Improvement Committee of the Australian Dairy Produce Board to again sponsor a similar competition during 1951-1952. The committee which receives funds from the Australian Dairy Produce Board and the Rural Credits Branch of the Commonwealth Bank, offered substantial cash prizes in the six zones as detailed below.

Mastitis, J Craig

Journal of the Department of Agriculture, Western Australia, Series 3

Mastitis, or inflammation of the udder, is responsible for tremendous losses to the dairying industry throughout the world. The disease may be caused by several different types of bacteria, the most common of which, the Streptococcus, is responsible for about 80% of all cases of mastitis. The Staphylococcus is involved in about 10% of cases and the remaining 10% are caused by other micro-organisms.

Strain 19 In Western Australia

Journal of the Department of Agriculture, Western Australia, Series 3

Since the inauguration of its brucellosis control campaign in 1946, the West Australian Department of Agriculture has inoculated nearly 72,000 dairy heifers with Strain 19 vaccine and established a remarkable degree of control throughout the dairying districts. As the success of the control measures is largely dependent upon the vaccination of each year's crop of heifers, the work is now being intensified and members of the field staff are again busy in the dairying areas.

Some Mechanical And Horomonal Methods Of Dilating The Bovine Cervix, Edmund F. Graham

Electronic Theses and Dissertations

The selection for certain inherited characteristics war practiced approximately 2000 years before the Christian Era. Jacob (Genesis 30:28-43) was given all the speckled cattle in his master’s herd for being herdsman. In a few years, by selecting for the spotting factor, only speckled cattle remained in the herd. Selection was the first tool for segregating definite characteristics. As a means of more rapid improvement artificial insemination was practiced by an Arabian chieftain as early as 1322 A. D. (35). Since 1322 these crude methods of transferring semen have been perfected until approximately four million cows were inseminated in the United …

The Improvement In Type Of South Dakota Dairy Cattle Through Artificial Breeding, Kenneth I. Gross

Electronic Theses and Dissertations

Body conformation is associated with function among all classes of livestock. Dairy cattle type deals with characteristics indicating ability to produce milk and butterfat economically along with breed character and other values of an aesthetic nature. In order to have economical milk and butterfat production, the dairy cow should possess that type of body conformation which is able to withstand the rigors of disease, reproduction and year after year milk production. A large percentage of dairy cattle sold in South Dakota and surrounding territory, whether for breeding purpose or commercial production, are evaluated primarily on the basis of their type. …

Feeding Milking Shorthorn Steers, M. L. Baker, V. H. Arthaud, C. H. Adams

Nebraska Agricultural Experiment Station: Historical Circulars

The objectives of the feeding work were to provide the producer with feed-lot data and where possible with slaughter data for Milking Shorthorn steers. As a definite breeding research program with the Milking Shorthorn herd was planned, it also was believed that information about the beef-making qualities of the steers should be of equal importance with milk and butterfat production records.

Some Economic Aspects Of The Fluid Milk Industry Of Nebraska, Kenneth E. Anderson

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Most citizens of Nebraska, especially the dairy farmers who produced milk for city consumption, are currently concerned with the problem of marketing fluid milk.In Nebraska and all over the United States, sales of wholesale milk farmers have been increasing for the past 15 years, while cream sales to creameries have been decreasing.

Production of milk in Nebraska is greatest in the eastern part of the state.Likewise, consumption is concentrated in Eastern Nebraska. This is most likely due to Eastern Nebraska’s highly concentrated population as well as the most favorable farm conditions for dairy cows.

Most of the bottled milk in …

Effects Of Aureomycin In Milk Used For The Manufacture Of Cheese, James A. Banghart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Importance of project:

In recent years many antibiotics have come to the foreground as a treatment for mastitis. Aureomycin is one of the more recent antibiotics that has been used for this purpose.

Aureomycin has been reported to be successful in curing some types of mastitis, but milk produced by cows that have been treated with Aureomycin does not act normal in the cheese manufacturing process. The most noticeable effect in milk from cows treated with Aureomycin has been slow or complete cessation of acid production by bacteria in cultured dairy products; this has been especially true in the cheese …

The Effect Of Common Contaminants On Cheese Starter, Ivan R. Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Starter is the "heart" of the cheese making industry. Only by proper handling of starter can good quality cheese be made. The economic loss from contaminated starter may prove disastrous to a cheese plant if proper corrective measures are not taken.

Milk usually contains a variety of bacteria. Under plant conditions some of these bacteria get into the mother starter or bulk starter unless extreme caution is used. Comparatively little is known about how one organism influences another when grown in milk. This problem is important in the cheese industry.
