Beef Cattle And Capital, Oliver A. Hansen

South Dakota Cow-Calf Field Day Proceedings, 1972

Though some of the areas of our states vary to a great extent, I'm sure you are witnessing in a good portion of South Dakota the same situation we have in Iowa -- a change in the entire pattern and concept of beef cattle production and feeding.

Coyotes And Their Control, Cooperative Extension South Dakota State University

SDSU Extension Fact Sheets

The coyote is the official state mammal in South Dakota and the official mascot at the University of South Dakota. Despite their apparently prestigious position in the state, coyotes have been the target of an intensive control effort for many years. This campaign was initiated because of coyote depredation on poultry and livestock. Overall, however, the coyote's food habits benefit man because a large majority of its diet consists of nuisance animals and carrion.

The Effects Of Mating And Management Systems On Beed Production Angus-Charolais Crossbreeding Project, W. R. Parker, C. A. Dinkel

South Dakota Cow-Calf Field Day Proceedings, 1972

Angus and Charolais heifers purchased in 1968 as weaning calves were used to initiate a crossbreeding project at Brookings. In phase I of this project these heifers were mated by artificial insemination to either an Angus or Charolais bull to produce straightbred Angus, straightbred Charolais, Angus x Charolais and Charolais x Angus calves. (Crosses are denoted in this report with breed of sire listed first.) Three such calf crops have been produced. The heifers from these three calf crops are being used in phase II of the project which consists of a long-term comparison of straightbred and crossbred cows in …

Development Of Techniques For Distribution Of Baits To Raccoon For Chemosterilant Studies, Richard L. Nelson

Electronic Theses and Dissertations

Sudan Red IV, Sudan Black B, and demethylchlortetracycline (DMCT) were tested as physiological markers in baits for raccoon (Procyon lotor). DMCT was readily detected in the jawbone of raccoons given 50 mg when examined under an ultraviolet light at period of 7, 30, 75, and 450 days following treatment. Seven days after administering 75 mg of Sudan Red IV, it could not be detected in fat deposits. Sudan Black B, administered in similar dosage, could not be detected at 30 days. A total of 1826 chicken eggs containing 50 mg DMCT was distributed on a 25 square-mile study area between …

Food Selectivity Of The Black Bullhead (Ictalurus Melas, Rafinesque) In Lake Poinsett, South Dakota, Andrew J. Repsys

Electronic Theses and Dissertations

The food habits of young-of-the-year, subadult and adult black bullheads were studied in Lake Poinsett, South Dakota, from March, 1970, to April, 1971. Two hundred twenty young-of-the-year (37-87 mm total length) fed primarily on limnetic cladocerans and copepods. Leptodora and Diaphanosoma comprised 86.5% of the total food volume. Chironomid larvae and pupae made up 5.6% of the total. Other benthic organisms and littoral cladocerans together contributed less than 1%. Stomach contents of 608 subadult and adult black bullhead (143-304 mm total length) indicated significant seasonal vairaiton in diet. Daphnia pulex and chronomid larvae were important food items in winter. Bullheads …

Influence Of Weather On Movement And Habitat Use Of Hen Pheasants During Brood Rearing, James M. Ruth

Electronic Theses and Dissertations

Pheasants survive in a wide range of yearly weather extremes but can be limited by certain short-term weather factors (Graham and Hosterburg 1948). Study of short-term weather conditions can therefore be important in understanding pheasant survival. Many studies have been done on yearly and seasonal effects of weather on pheasant production and survival. Bemitt and Terril (1940) reported on possible temperature factors in pheasant management in the north central area of the United States. Effects of weather on pheasant reproduction were studied by Buss and Swanson (1950) and Kozieky et al. (1955). MacKullan and Eherhardt (1953) studied the tolerance of …

Food Habits Of Fish In A Multispecies Farm Pond, Thomas W. Gengerke

Electronic Theses and Dissertations

Food habits of yellow perch, bluegill, and black crappie were studied during 1970 and 1971 in Abbey Pond, South Dakota. Aquatic insects, zooplankton, mollusks, and fish were the most frequently consumed food items by the three species. Yellow perch led primarily on aquatic insects, zooplankton, and mollusks. Aquatic insects were dominant (by volume) in 40.0 and 61.5 percent of the samples respectively for the two years. Zooplankton, mollusks, aquatic insects, and bryozoans were the dominant food items by volume of adult bluegills. On an annual basis aquatic insects were the most important food item in the diet. Adult black crappies …

Gentilesse And Gentility : Moral Criticism In The Novels Of Charles Dickens, Phyllis Anderson Ballata

Electronic Theses and Dissertations

There has been a considerable revival of interest in Dickens in the last thirty years. "As Bernard Darwin said when critical interest in Dickens was just beginning to gain momentum, ‘Mr. Pickwick once took another glass of punch just to see whether there was any orange-peel in it, because orange-peel always disagreed with him; and we can now all read Dickens yet again just to see if we were wrong about him.'" Edmund Wilson's seminal essay “Dickens: The Two Scrooges" appeared first in 1940 and again in The Wound and the Bow in 1947. Humphrey House's valuable Dickens World came …

Similitude Study Of Airflow Characteristics And Evaluation Of Ridge Vent Design For An Open Front Confinement Beef Barn, Ivar R. Dybwad

Electronic Theses and Dissertations

Predictions for the future indicate that beef cattle production will continue to increase. The U. S. Department of Agriculture has estimated that the demand for red meat would increase by over 60 per cent between 1958 and 1975. Beef consumption in the United States is 80 to 85 pounds per capita per year. However, some light meat, turkey and chicken will be substituted for red meat, but due to the continuing increase in human population, the production of beef will have to increase to meet the domestic need. Following the trend of the last few years, more beef cattle production …

Carboxymethylcellulose As A Carrier For Follicle Stimulating Hormone In The Female Rat And Bovine, C. Leroy Johnson

Electronic Theses and Dissertations

A series of biological assays were conducted to compare physiological saline (PSS) and carboxymethylcellulose (CMC) as carriers for follicle stimulating hormone (FSH) and to determine the optimum ratio of FSH to CMC. Constant individual dosages of 0.5 mg FSH were injected into a total of 384 immature female rats in four experiments. Treatments included single injections of FSH in PSS, FSH in 1 percent CMC at ratios (mg FSH: ml CMC) OF 1:3, 1:2, 1:1, 2:1, 3:1, 5:1 and FSH in 2 percent CMC at a ratio of 1:1.

Evidence For The Presence Of Two Nucleases In Barley Tissue And The Influence Of Genotype On Their Properties, Clay G. Johnson

Electronic Theses and Dissertations

Several lines of evidence have shown that genetic variability exists within the barley species (Hordeum vulgare L.) with respect to the kinetics and specificity of yeast ribonucleic acid degradation. Initial efforts demonstrated that ribonuclease (RNase), in the crude soluble protein fraction from the cultivar Dicktoo, was inhibited by KC1 and phosphate. RNase activity was enhanced if heated to 60 C for short periods. In contrast, RNase in the crude soluble protein of the cultivar Tennessee Winter showed no altered response by either KC1 or phosphate. Maximal RNase activity was at pH 5.0 for extracts of both cultivars (0.16 M KC1), …

The Effect Of Allopurinol (4-Hydroxypyrazolo(3,4-D) Pyrimidine) On Uric Acrid Metabolism In Differential Grasshoppers (Melanoplus Differentialis) And Armyworms (Pseudoletia Unipuncta), Henry C. Schroeder, Jr.

Electronic Theses and Dissertations

Allopurinol, a potent inhibitor of xanthine oxidase in humans, was incorporated in the diets of differential grasshopper nymphs and adults and armyworm larvae. Uric acid contents of whole body homogenates decreased by highly significant rates. Feces uric acid decreased by highly significant rates in grasshopper nymphs and adults. Allopurinol also caused highly significant increases in mortality and inhibition of metamorphosis in study insects. These effects were not reversible by the addition of purine and pyrimidine bases, inosine, oxypurines, or uric acid. The effects were reversed by discontinuing application of allopurinol. Crude xanthine oxidase, assayed by measuring the reduction of NAD …

Urban Insurrections: A Multi-Disciplinary Approach Toward An Integrated Typology, James Russell Stewart

Electronic Theses and Dissertations

The purpose of this study is to investigate the possibility and appropriateness of employing a multi-disciplinary approach in the study of urban insurrections in an effort to construct a typology which would include all of the elements common to each disorder. The multi-disciplinary method is necessitated by the biases which are inherent in any analysis that is restricted to either a psychological, sociological, or politico-historical treatment of episodes of collective behavior. All of the disciplines make major contributions to any analysis, but it is the contention of this writer that the disciplines must be integrated before the most accurate depiction …

Effects Of Manganese Chloride On Gravid Gilts And Newborn Pigs, Dale A. Wade

Electronic Theses and Dissertations

Excessive dietary manganese in young mammals has depressed hemoglobin levels, red blood cell synthesis and growth in some investigations, while in other research these were increased. Toxic levels, mode of action and specific physiological effects are unknown although manganese, cobalt and iron appear to compete for absorption mechanisms. Manganese functions in enzyme systems and in carbohydrate and lipid metabolism, is present in red cells and plasma and may be incorporated into the hemoglobin molecule. Gravid gilts were utilized in these investigations since piglet anemia is an economic problem and manganese effects in swine have not been fully defined. Gilt rations …

Amino Acid Supplementation Of Low Protein Layer Diets, Harlal Choudhury

Electronic Theses and Dissertations

Experiments were conducted at the South Dakota State University Poultry Research Center to study the effects of amino acid supplementation of low protein diets on performance of laying type hens. Hans, housed in 8-inch cages, were fed at 24 weeks of age typical 16% protein corn-soy diets diluted with glucose to 10.8% protein and supplemented with 0.15% DL-methionine, 0.19% L-lysine and 0.04% DL-tryptophan. After about 20 weeks of depletion, supplements of 0.05 and 0.1% DL-threonine and DL-valine and 0.1% DL-isoleucine alone and in all combinations were fed for a further period of 16 weeks using a factorial design. Individual supplements …

Effects Of Polychlorinated Biphhenyls In The Ring-Necked Pheasant, Robert Bernard Dahlgren

Electronic Theses and Dissertations

In 1970 and 1971, cock pheasants (Phasianus colchicus) were given single capsules weekly containing 0 and 25 mg polychlorinated biphenyls (PCB), Aroclor 1254, and hens were given O, 12.5, and 50 mg. Egg production was reduced (P<0.01) in the hens given 50 mg PCB both years. Fertility, determined by visual inspection of incubated eggs, was unaffected by PCB. Hatchability was lowest in the group of hens given 50 mg in both years but significantly lower (P<0.01) only in 1971. PCB adversely affected the viability of the embryo both years, as the number of eggs pipped but not hatched in PCB groups was higher (P<0.05). PCB did not affect eggshell thickness. Behavior on the visual cliff shortly after hatching was affected among offspring of hens given 50 mg PCB in 1970 (P,0.01). Offspring of hens given 50 mg chose the visually-deep side of the cliff. No differences in behavior on the visual cliff were evident in 1971. Response to hand catching of offspring was affected in 1970 (P <0.01). The ability of penned pheasants to avoid hand capture was least where both parents received PCB, followed by those where hens only, cocks only and neither parent received PCB. No differences in response to hand capture among groups were found in 1971. Weights of chicks from hens on 50 mg were lower (P<0.01) at 6 weeks of age in 1970. This effect was not seen in 1971. Survival of chicks in brooders to 6 weeks of age was lower (P<0.01) in offspring of hens given 50 mg PCB weekly in 1970. No differences were found among offspring of treatment groups in 1971. Survival from 6 weeks of age to fall was similar in all groups. Overall survival from hatching to fall was less (P<.0.05) in offspring of hens given 50 mg weekly in both years combined. No differential effect was found between sexes for survival. PCB in doses varying front 10 mg to 210 mg daily caused hyper-excitability, weakness, tremoring, lack of appetite, lack of feathers, and a comatose death. Birds 11-weeks old given 10 or 20 mg PCB daily, birds 6 to 9 months old given 50 or 100 mg each 3.5 days, and adult hens given up to 50 mg once a week continued to eat. Eleven-week old birds given 210 mg daily stopped eating or those given 210 mg daily, the heaviest birds lost the greatest percentage of their weight (15 to 31 percent) before death occurred (1.3 to 4.3 days). Birds intentionally starved at the same time lost a greater percentage of weight (27 to 51 percent) before death (2.3 to 8.6 days). Some adult hens were given a single 50-mg capsule and samples of whole body, brain, liver, muscle, eggs, and feces were analyzed to determine patterns of storage and excretion. Levels of PCB were highest at 12 hours after capsule administration. Residues were highest in liver, followed by brain and muscle over 28 days following the single 50-mg capsule. From 94 to 98 percent of the administered dose was absorbed and 40.5 mg of the 50mg were in the body after 28 days. Hens were in a state of low egg production and excreted 4.2 mg in the eggs and 4.0 mg in the feces over 28 days. Excretion in the egg could be an important means of ridding the body of PCB. Four hens from the 1970 breeding experiment, given 17 capsules weekly containing 12.5 mg PCB and killed 1 week following the last capsule, had from 37 to 56 percent of the administered dose in their bodies. Four hens on the 50-mg level in 1970 had from 60 to 82 percent of the dose given. Five hens given 12.5 mg weekly for 16 weeks in 1971 had an average of 23.8 ppm PCB in their bodies 1 week after the last capsule, three hens had an average of 13.6 ppm after 3months on a clean diet, and three others had an average of 20.9 ppm after 6 months. Excretion was variable and slow. An analysis of brain, liver, and muscle tissues from dead and surviving birds fed PCB at various levels showed that brain residue levels from 300 to 400 ppm wet weight were indicative of death from FCB toxicosis. Liver and muscle levels were too variable to be useful in assessing cause of death. Administration of PCB decreased weights of heart and spleen (P <0. 01) at all levels given and increased weights of kidneys and livers in birds given 10- and 20-rng doses daily (P <0. 01) but not in birds given 210 mg daily. Splenic atrophy, where spleens were small, pale-tan color, and had wrinkled capsules resulting from depletion of lymphatic nodules, was characteristic of birds given PCB. PCB and dieldrin were given singly and jointly, and only additive, not synergistic, effects were noted. Livers of wild pheasants from Pennsylvania, Indiana, and South Dakota had no more than 2 ppm PCB. This indicates low-level contamination.
