The conflicting problems involving the herds of mule deer (Odocoileus hemionus) are of major interest throughout Utah. Individuals who are affected the most are sportsmen, ranchers, fruitgrowers, sanitation engineers, home owners, federal administrators, and big game managers. Mainly, the problems arise as a result of insufficient forage, especially on the winter range. Here, factors such as increased deer numbers, decreased range productivity, severe winters, and expanded agricultural activity make more acute the problem of a naturally critical season.
Restoration of forage by artificial measures may be necessary as a management solution for certain areas. Range rehabilitation, rather than …

Mule deer provide recreational bunting to a large number of sportsmen in Utah, and also have a high aesthetic value.
Prior to settlement, deer are believed to have wintered in the valleys and lower foothill areas. However, in northern Utah agricultural development bas removed many valleys and lower foothill areas from the available winter range. The winter deer range in this area has therefore been restricted to a relatively small area of foothill country, and low elevation mountain slopes and benches.
The Use Of Lactic Acid In The Manufacture Of Cheddar Cheese From Milk Containing An Antibiotic, Elmer George Jr.
The Use Of Lactic Acid In The Manufacture Of Cheddar Cheese From Milk Containing An Antibiotic, Elmer George Jr.

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.
Lactation Curves Of Holstein Cows As Influenced By Age, Gestation, And Season Of Freshening, George Edward Patterson
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.
Factors In The Development And Restoration Of Waterfowl Habitat At Ogden Bay Refuge Weber County, Utah, Noland F. Nelson
Factors In The Development And Restoration Of Waterfowl Habitat At Ogden Bay Refuge Weber County, Utah, Noland F. Nelson

Millions of acres of marshland have been destroyed by the industrial and agricultural development of this continent. Drainage, water diversion, land leveling, and some other factors which destroyed waterfowl habitat were in most instances essential steps in man's progress; but water pollution, unwise drainage, and other soil and water abuses were tragic and unessential steps in our history of land exploitation that have destroyed vast acreages of habitat. The future of waterfowl on this continent hinges upon the success of restoration or new marsh development to replace this destroyed habitat.

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 …
Evaluation Of Stream Bottom Fauna Sampling Techniques As Used In The Logan River, Donald C. Hales
Evaluation Of Stream Bottom Fauna Sampling Techniques As Used In The Logan River, Donald C. Hales
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Since the square-foot bottom sampler was described by Surber (1937) it has been the principle instrument used for quantitative studies of the bottom fauna in riffle areas of streams. However, little has been written concerning the actual number of square-foot samples necessary to describe stream bottom fauna in terms of the number or volume of organisms.
