The Effects Of Acute Ammonia Toxicity On Certain Homogram Parameters In Sheep, William C. Kirkpatrick

Electronic Theses and Dissertations

Due to the rapidly expanding human population, one of the greatest problems facing agricultural scientists is the development of adequate food resources to meet the growing demand for quality protein. The development of more economical and higher quality feed for ruminant animals is essential since they are one of man's primary sources of animal protein. Microorganisms in the ruminant stomach convert relatively cheap non-protein nitrogen compounds into bacterial proteins, which are digested, absorbed, and utilized by the host animal. Urea, a common non-protein nitrogen compound, is hydrolyzed into ammonia and carbon dioxide by bacterial urease. When urea is hydrolyzed faster …

The Use Of Iodine And Chlormadinone Acetate To Suppress Sexual Maturity In Chickens, Curtis Eldon Holmquist

Electronic Theses and Dissertations

Researchers, for several years, have tried various methods of retarding the onset of egg production in chickens. Some reports have shown that a delay in sexual maturity is beneficial. When comparing restricted pullets to unrestricted control groups, these reports reveal economic advantages of restriction in that restricted pullets have lower total feed costs, improved egg size, improved total egg production and a lower percentage of mortality during the production cycle. Other research has accomplished restriction with no resulting advantages. These discrepancies may be due, in part, to inaccurate means by which the results of restriction have been measured. Confinement rearing …

Various Forms Of Dehydrated Alfalfa In High-Concentrate Cattle Finishing Diets, Jerry D. Burkhardt

Electronic Theses and Dissertations

Even though growing and finishing beef cattle have been fed satisfactorily on all-concentrate diets, in many instances weight gains have been improved and management problems reduced by including some conventional form of roughage in the diet. The most efficient level of roughage will likely be a variable factor depending upon a number of things including weight and condition of the cattle and. nature of the roughages and concentrates. It is a well-established fact that .as the energy content of the diet increases the rate of gain increases and the feed required per unit of gain decreases. In addition to rate …

The Effects Of Erythropoietin, Dibenzyline, And Iron Dextran On The Hemogram Of Doe And Fetal Rabbits, Eugene Austin Gardner

Electronic Theses and Dissertations

The iron deficiency anemia found particularly in swine has a high incidence in the newborn. The nutrition of the sow inversely affects progression of the anemia. Newborn nutritional status, also, inversely augments the anemic condition. The anemia does not become apparent in the newborn until a few days following parturition. There is a drastic decrease in iron availability with succeeding decreases in normal hemoglobin formation and mature red blood cell formation. An important factor along with these conditions is susceptibility to disease leading to death. A gradual return to normal follows if the newborn survives the anemic period. This condition …

Partial Cooling Of The Environment In Free Stalls For Sows During Farrowing And Lactation, Thomas R. Gannon

Electronic Theses and Dissertations

Many of the technological advances in the swine industry have resulted in increased capital requirements for buildings and equipment. This has made multiple farrowing, including summer farrowing, a near necessity. Hog farmers recognize the problem of sow mortality due to severe heat stress during periods of high ambient temperatures, and hog producers utilizing the free stall farrowing system recognize yet another problem, that of poor stall occupancy. Sows in this type of system tend to seek relief by leaving their stalls and lying in moist or breezy areas. This decreased stall occupancy has resulted in pigs being severely neglected, reduced …

Effects Of An Appetite Suppressant And Exercise Upon Selected Physiological And Anthropometric Measurements In Overweight College Women, Jo Ann Krause

One individualized program is for the overweight and the complications both physical and emotional which result from it should be of immediate concern in the planning of the physical education curriculum. However, there is evidence that the best interests of the overweight student have for the most part been overlooked, Programs to combat overweight should be constructed to include physical exercise …

Prediction Of Beef Palatability Factors And Relationships Between Live And Carcass Traits, Richard J. Berns

Electronic Theses and Dissertations

The agricultural industry or South Dakota is primarily based on the beer cow and her products. Cattle feeders had 275, 000 head of cattle and calves on feed on July 1, 1970, a 2 percent increase over July 1, 1969. South Dakota has about 1, 719, 000 beef cows which is 38 percent more than a decade ago. The state can continue to increase beef production in many ways such as retaining mare cows to produce feeders, increasing calving percentage, using crossbreeding, or feeding cattle to heavier weights. Increased carrying capacity through irrigation and management may be another avenue to …

The Effect Of Age, Preparation Method, Storage Time, And Storage Temperature On The Palatability And Fatty Acids Of Freeze-Dried Pheasant, Shirley J. Mittan

Electronic Theses and Dissertations

Freeze-dehydration is a relatively new method being used in food preservation. Dehydration of food is an ancient procedure, but the freezing of food has come into common use since the turn of the century. The combined procedure of freezing and dehydration is a new innovation. Most of the work on freeze-dehydration has been done within the last two decades. Freeze-dehydration is a process in which the foodstuff is frozen; while still in the frozen state, the moisture is withdrawn under vacuum. An advantage of this method of processing is that the moisture content of the foodstuff can be reduced to …

Review Of Research Of The Value Of High Moisture Corn For Growing And Finishing Swine, L. J. Kortan

South Dakota Swine Field Day Proceedings and Research Reports, 1970

Work at South Dakota State University during the 10 year period 1942-1951 with soft corn for growing-finishing pigs showed that hogs are well adapted to utilize soft corn. In all six trials during this period, pigs fed soft corn showed a lower rate of gain per day than the pigs fed hard corn. However, when the soft corn was dried and fed, the pigs made practically the same rate of gain as the pigs fed hard corn. Compared on a dry matter basis, the value of soft corn was practically equal to hard corn for growing pigs. However, the pigs …

The Effect Of Gestation Energy Levels On Reproductive Performance Of Sows And Gilts, George W. Libal, Richard C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1970

Restricting energy on total feed intake has been accepted as a desirable management pract ice for gestating sows and gilts. The advantages are reduced feed costs during gestation and larger and stronger litters resulting from more proper nutrition of the gestating sow. The common practice of reducing total feed level quite of ten reduces daily intake of energy protein and many of the other nutrients required by the sow. The experiment reported herein is an attempt to establish minimum required levels of metabolize energy for gestating sows and gilts under both summer and winter conditions. These sows will be maintained …

Can Selenium Increase Egg Production?, R. L. Arnold, C. W. Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1970

Selenium is a mineral element which is found as a natural substance in soil, plants and animals. Although it occurs in relatively small quantities it has frequently been found in toxic amounts in some parts of South Dakota. Recent studies have shown it to be essential and it is being regarded in animal nutrition as a valuable trace element. Other trace elements such as copper and iodine have been shown to be beneficial in animal diets and are routinely added to feeds. In order to study what effects added selenium would have in chicken diets we conducted the following experiment.
