Group Grain Feeding Versus Individual Grain Feeding Of Lactating Dairy Cows, Earl Max Sudweeks May 1962

Group Grain Feeding Versus Individual Grain Feeding Of Lactating Dairy Cows, Earl Max Sudweeks

All Graduate Theses and Dissertations

Grain feeding is an important part of a dairy feeding program. Grain supplies energy in a concentrated form and when fed as a supplement to forage permits cows to maintain high levels of production. Also, if the forage is of low quality, additional protein and other nutrients can be supplied with the grain in a concentrate mix. By feeding a balanced concentrate mix, according to individual production, each cow receives the necessary nutrients for production. Dairy cows are usually fed grain individually.

During recent years dairy herds have increased in size and milking parlors have been developed in which to ...


Influence Of Age On Milk Production Of Holstein Cows In Utah, Marvin R. Green May 1962

Influence Of Age On Milk Production Of Holstein Cows In Utah, Marvin R. Green

All Graduate Theses and Dissertations

Production of dairy cows is influenced by many factors, among which are: genetics, nutrition, management, disease and age. Most of these factors can be modified to maintain a high level of production. Age, however, is beyond the influence of mankind; therefore, it is important to understand the effect of age on milk and butter-fat production.


A Study Of The Use Of The Hydrogen Peroxide-Catalase Treatment Of Milk In The Manufacture Of A Reduced Fat, Cheddar-Like Cheese, Lamar John Johnson May 1962

A Study Of The Use Of The Hydrogen Peroxide-Catalase Treatment Of Milk In The Manufacture Of A Reduced Fat, Cheddar-Like Cheese, Lamar John Johnson

All Graduate Theses and Dissertations

Nutritionists, the medical profession, and the public in general have become increasingly interested in low fat food products. Cheddar cheese, as it is now made, has a high caloric value and therefore may be discriminated against in some diets. The production of a reduced fat cheddar-like cheese would be of importance to the cheese industry by providing a reduced fat, high protein product.

The chemical nature of the casein furnishes the foundation for the body and texture in cheese. The body and texture of typical cheddar cheese is influenced principally by its fat and moisture content.

The use of hydrogen ...


A Study Of The Effects Of Acidity On Shelf Life And Type Of Spoilage In Market Milk, Jagannath M. Kudale May 1962

A Study Of The Effects Of Acidity On Shelf Life And Type Of Spoilage In Market Milk, Jagannath M. Kudale

All Graduate Theses and Dissertations

The addition of the Streptococcus lactis culture in the pasteurized milk was studied, in an attempt to find the effects of the culture in prolonging shelf life of the milk. Various concentrations of the culture were tried to find the optimum concentration that would give favorable effect on keeping quality of the milk. It was found that the addition of Streptococcus lactis culture at the rate of 0.0001 percent has shown promising effects in prolonging shelf life of the milk at the storage temperature of 40 F.

In addition to the above study, effects of added acid in the ...


Factors Affecting The Waterfowl Hunter Utilization And The Waterfowl Kill At The Bear River Migratory Bird Refuge, 1960-61, Stephen V. Goddard May 1962

Factors Affecting The Waterfowl Hunter Utilization And The Waterfowl Kill At The Bear River Migratory Bird Refuge, 1960-61, Stephen V. Goddard

All Graduate Theses and Dissertations

With the goal of obtaining the maximum utilization of areas now open to public hunting in mind, a study was conducted at the Bear River Migratory Bird Refuge during the 1960 and 1961 waterfowl hunting seasons. The study had the following main objectives: 1) determine the level of utilization of the refuge by water fowl hunters including determining the factors which affect the utilization of various areas of the refuge, determining the factors and their influence on the kill composition in the various areas and the entire refuge, and obtaining quantitative and qualitative information on hunter population and the use ...
