Corn, oat hulls, solvent-extracted soybean meal, full-fat extruded soybeans, C-1 protein, casein and texturized forms of soy protein were added to the basal diet at various levels. All feedstuffs were added at two particle sizes: natural form of the feedstuff (>250 u); and ground in a ball mill (<250 >u). The effects of autoclaving for 60 minutes at 120°C were also investigated. …

Effects Of Various Levels Of Dietary Selenium And Arsenic On Chickens, Richard L. Arnold

Electronic Theses and Dissertations

Various levels of selenium and arsenic additions were made to several types of chicken diets to study their effects on growth and reproduction criteria. Three experiments were conducted. The first study involved day-old chicks and terminated at 64 weeks of age. These yearling hens were then used for the second experiments which terminated when the hens were 104 weeks old. The third study was initiated with 20 week old pullets and terminated when they were 52 weeks old. Feeding purified diets resulted in slower chick growth and lower mature body weights of hens. Selenium additions of 2.0 ppm resulted in …

The Influence Of Various Stress Conditions On Cholinesterase Levels Of Cattle Treated With An Organophosphorus Insecticide, Mitchell J. Wrich

Electronic Theses and Dissertations

Six-to 8-months-old Hereford heifers categorized as grubby or grub-free calves were used for this research. Forty calves were purchased in 1968 and also in 1969. The grubby calves were obtained from Highmore, South Dakota, an area where calves have a history of heavy grub infestations of both Hypoderma bovis (L.) and Hypoderma lineatum (de Villers). The grub-free calves were purchased in Fargo, North Dakota. Calves raised in this area seldom are infested with cattle grubs. Specified groups of calves were subjected to 30 minutes of continuous exercise or the withholding of feed and water for 24 hours prior to treatment …

Plant Analysis Of Spring Small Grains At Different Stages Of Growth, James Henry Pfeifer

Electronic Theses and Dissertations

Plant analysis has developed into a diagnostic tool for measuring the nutrient status of crops. Plant analysis promises to greatly supplement the methods now available for estimating nutrient sufficiency, and as a result, increase the yield of crops. For small grains, the sampling time recommended for plant analysis is the reproductive stage ·of growth. This period has been used to determine nutrient concentrations of N, P, K, Ca, Mg, S, Zn, Mn, and Fe. Much concern exists with regards to the accuracy of plant analysis in predicting the nutrient status of small grain plants. Concern spring wheat, and barley under …

The Relationship Of Porcine Muscle Fiber Size And Number To Management, Meatiness And Quality, Ronald J. Smith

Electronic Theses and Dissertations

For many years animal scientists have been striving to find the “foolproof” method foreseeing the desired carcass and consumer characteristics in live animals before they are slaughtered. As a result, several different live animal and carcass evaluation techniques have been developed and tested with slow but encouraging success in some areas. This “never-ending” search has been stimulated by the development of new and more sophisticated research tools and facilities as time advances. Increasing consumer demands for a muscular, trim, high quality meat product makes identification of these desired traits in the live animal and carcass necessary. Thus, the producer, feeder …

Metabolism Of Urea Nitrogen By Rumen Ciliate Protozoa, Alan Lewis Vogel

Electronic Theses and Dissertations

A Characterization Of Four Prairie Grasses, Carolyn A. Cogswell

Electronic Theses and Dissertations

Even though native range forages have been available a long time, there is little research data concerning the specific grasses characterized as native forage or browse. Little research has been done to study these forages because of their natural habitat far from research laboratories, the task of collecting enough forage for adequate sample testing, and sparse yet hardy existence and questionable known vegetative growth with each year's different climate and environmental conditions. Certainly it seems logical that at some future time the knowledge of their nutritive value will become important. Perhaps then with adequate management the rancher can improve upon …

Pasture Supplementation Of Beef Cattle Followed By Drylot Finishing With High-Concentrate Rations And Antibiotic Supplement, Cecil R. Graber

Electronic Theses and Dissertations

The objectives of the research reported in this thesis were to determine the effects of various levels of pasture grain feeding on pasture weight gains as well as on subsequent gains and feed requirements in drylot. The value of an antibiotic was tested at various levels to determine the effects in rapidly getting cattle on full feed of a high-concentrate ration. The effects of the various levels of the antibiotic were also studied when administered for five consecutive days at monthly intervals throughout the experiment.

Effects Of Delactosed Whey, Skim Milk, And Sugar On Ration Palatability And Performance Of Early Weaned Pigs, Larry A. Hauser

Electronic Theses and Dissertations

There has been much interest in the possibility and feasibility of weaning pigs at an early age with attempts to wean pigs as early as one to two hours post-partum. Most workers, however, have concentrated their studies upon weaning at two to four weeks of age. When pigs are weaned at this early age, it is important to utilize feedstuffs that will result in an economical, highly palatable, starter diet that will provide rapid and efficient pig gains. Therefore, the diet must provide all of the essential nutrients in a readily available form and at a cost which is not …

Temperature Computer Measurements, Production And Carcass Traits Of Individually Fed Weight Constant Steers, Lowell M. Anderson

Electronic Theses and Dissertations

During 1968, 29 Hereford steers were individually fed and marketed at one of seven constant weight classes from approximately 386 to 522 kg at intervals of 22.7 kg. During 1970, 21 Angus and Hereford crossbred steers were individually fed and marketed at one of four constant weight classes from approximately 386 to 522 kg at intervals of approximately 45.0 kg. The amounts of edible portion, trimmed fat, removed bone and the summation of the kidney, pelvic, and cod fat were determined on the steers of both years. In 1970 two experiments examined the usefulness of an analog computer for calculation …

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

Electronic Theses and Dissertations

Leaders in the field of physical education constantly urge that programs of physical education be based on the needs of all students. Educators have the professional obligation to develop special programs to meet the unique requirements of the individual. 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 …

Flavor Preference And Stability Of A Low-Fat Dairy Spread, James Robert Miller

Electronic Theses and Dissertations

Low-fat dairy spread has been defined as a product which contains only dairy ingredients and has a lower fat content than the commonly used spreads, butter and margarine (5). Although some low-fat spreads have contained very little fat, most of those which have been developed during the past 30 years have contained about one-third to two-thirds as much fat as the commonly used spreads and have had a higher protein content. ·The low-fat dairy spread studied in this project contained about ten times more protein and only one-half as much fat as butter and margarine. The present day justification of …

The Effect Of Sodium Hexametaphosphate On The Palatability Of The Freeze-Dried Chicken, Ngoc Hoa Giang

Electronic Theses and Dissertations

Freeze-drying has been generally regarded as the mildest method known for drying meats, but even this process has caused undesirable changes in meat quality. The texture of rehydrated freeze-dried meat has been found to be tougher and drier than untreated meats. In addition, the meat may have a "woody" texture. Apparently something has occurred during the freeze-dry process that reduced the water-holding capacity of the meat. This has been reflected in the meat's inability to become fully rehydrated. Sodium hexametaphosphate (SHNP) has been used successfully to increase the water-holding capacity of meat and fowl. No study has been conducted to …
