Chinook Climates And Plains Peoples, Reid A. Bryson Jan 1981

Chinook Climates And Plains Peoples, Reid A. Bryson

Great Plains Quarterly (through 2013)

Changes in climate are major factors shaping the history of human occupance in the Great Plains region. Although Americans have often acted as though climates are fixed, the record indicates that in the past the climate of the Great Plains has changed drastically over relatively short periods of time. In order to acquire some understanding of what the Great Plains climate may become in the future and how human society may prepare for it, we must first comprehend what it was at various times in the past.

CHINOOK CLIMATES

An important element in the climate of the American West is …


Rölvaag, Grove And Pioneering On The American And Canadian Plains, Dick Harrison Jan 1981

Rölvaag, Grove And Pioneering On The American And Canadian Plains, Dick Harrison

Great Plains Quarterly (through 2013)

Ole Rölvaag's Giants in the Earth and Frederick Philip Grove's Fruits of the Earth are not obvious choices with which to begin comparing the pioneer fiction of the American and Canadian plains. Giants, translated from the Norwegian, is about Helgelander fishermen settling in the wilds of Dakota Territory in 1873 and, with little more than their bare hands, trying to farm the alien prairie and establish rudimentary institutions of family, church, school, and local government. Fruits, written in English, is about an Anglo-Saxon farmer from Ontario who brings equipment and capital to the task of building an empire …


Effect Of Level Of Dietary Calcium-Phosphorus During Growth And Gestation On Calcium-Phosphorus Balance And Reproductive Performance Of First-Litter Sows, R. D. Nimmo, E. R. Peo, Jr., J. D. Crenshaw, B. D. Moser, A. J. Lewis Jan 1981

Effect Of Level Of Dietary Calcium-Phosphorus During Growth And Gestation On Calcium-Phosphorus Balance And Reproductive Performance Of First-Litter Sows, R. D. Nimmo, E. R. Peo, Jr., J. D. Crenshaw, B. D. Moser, A. J. Lewis

Department of Animal Science: Faculty Publications

Twenty-four bred gilts were used in a Ca-P metabolism trial. Twelve gilts were fed gestation treatment A (13 g Ca, 10 g/day), while the other 12 were fed gestation treatment B (19.5 g Ca, 15 g P/day). One-half of the gilts in each treatment group were fed .65% Ca, .50% P from 7 to 94 kg, and half were fed .975% Ca, .75% P for the same period. Treatment B gilts excreted more (P<.005) fecal and urinary P. Twenty-four first litter sows fed the same treatment diets during growth and gestation and given .75% Ca, .50% P during lactation were used in a Ca and P balance trial conducted from day 38 to 42 of lactation.

Influence Of Age, Sex, And Calcium And Phosphorus Levels On The Mechanical Properties Of Various Bones In Swine, T. D. Crenshaw, E. R. Peo, Jr., A. J. Lewis, B. D. Moser, D. Olson

Department of Animal Science: Faculty Publications

Seventy-two 4-week-old pigs were randomly assigned by sex (gilts, barrows, boars) to two dietary treatments and four age periods for determinations of the effects of age, sex and Ca and P levels on the mechanical properties of various bones in swine.


Comparisons Of Mating Systems With Duroc, Hampshire And Yorkshire Breeds Of Swine For Efficiency Of Swine Production, E. R. Wilson, R. K. Johnson Jan 1981

Comparisons Of Mating Systems With Duroc, Hampshire And Yorkshire Breeds Of Swine For Efficiency Of Swine Production, E. R. Wilson, R. K. Johnson

Department of Animal Science: Faculty Publications

Estimates of direct and maternal genetic and heterosis effects for purebreds and crosses among the Duroc, Hampshire and Yorkshire breeds were made from data on 1,243 litters from the Oklahoma crossbreeding experiment. The estimates were used to simulate the production efficiency of 21 mating systems. Each mating system was defined to include purebred, crossbred and commercial matings needed to maintain 10,000 farrowings. Linear programming was used to maximize the number of Yorkshire equivalent pigs foreach system. An index of economic weights for days to 100 kg, feed efficiency and probe backfat (traits expressed as a deviation from Yorkshire) was calculated …


Heg81-143 Meat Storage Guidelines, H. Dwight Loveday, Sheri Horn Jan 1981

Heg81-143 Meat Storage Guidelines, H. Dwight Loveday, Sheri Horn

University of Nebraska-Lincoln Extension: Historical Materials

Because meat is a highly perishable food item, extra care and attention are needed to ensure that a high quality, wholesome product is served.

Unwholesomeness and spoilage of meat are caused by bacteria and other microorganisms. This contamination generally occurs during cutting and processing. These bacteria require three conditions for growth:

low acidity (near neutral pH) level within the meat;

an available supply of water or other moisture, such as meat juices;

a warm temperature -- generally between 45° and 127°F.

Therefore, to prevent spoilage and the possibility of food borne illness, precautions must be taken to control these three …


G81-548 Organic Gardening In The Backyard (Revised June 1990), Dale T. Lindgren, Don Steinegger, Frederick P. Baxendale, John E. Watkins Jan 1981

G81-548 Organic Gardening In The Backyard (Revised June 1990), Dale T. Lindgren, Don Steinegger, Frederick P. Baxendale, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Successful organic gardening requires consideration of many factors, including resistant cultivars, crop rotation, sanitation, incorporation of organic matter, garden location, and insect and disease control.

Organic gardening is growing in popularity. Although this technique traditionally has been limited to backyard gardens, commercial organic farms now exist in Nebraska. The phrase "organically grown" generally refers to produce grown and processed without the use of synthetic organic chemicals in pesticides, fertilizers, preservatives, or flavorings. The main arguments for organic gardening are that food is less likely to contain potentially harmful chemicals and that fewer chemicals are released into the environment. Arguments against …

G81-538 Brooding And Rearing The Home Meat Flock, Earl W. Gleaves Jan 1981

G81-538 Brooding And Rearing The Home Meat Flock, Earl W. Gleaves

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses raising chickens for meat.

The objective of owning and raising a home flock should be to satisfy needs other than income production. For example, many people prefer fryer-type chickens of heavier weights to the lighter weight ranges available in many stores. Product freshness is the objective of some home flock owners; others are interested in the small flock in much the same way that some people are interested in a garden. A well-managed home flock can be a good source of fresh poultry meat. However, home flock producers should not plan to raise more birds than their …


G81-563 Grazing Management Of Irrigated Grass Pastures, James T. Nichols Jan 1981

G81-563 Grazing Management Of Irrigated Grass Pastures, James T. Nichols

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses factors and principles of plant growth that influence irrigated pasture production; suggests management practices that allow irrigated pastures to express their production potential; and suggests stocking rates for various levels of production and classes of cattle.

Grazing management has a major impact on the production potential from irrigated pasture. Proper management practices can maximize pasture production -- poor management ultimately results in unacceptable production levels.


The Myth Of Lesbian Impunity Capital Laws From 1270 To 1791, Louis Crompton Jan 1981

The Myth Of Lesbian Impunity Capital Laws From 1270 To 1791, Louis Crompton

Department of English: Faculty Publications

The standard history of antihomosexual legislation states that lesbian acts were not punished by medieval or later laws. This essay challenges this view by documenting capital laws since 1270 in Europe and America. A major influence was Paul's condemnation in Romans I, 26. By 1400, the lex foedissimam, an edict of the Emperors Diocletian and Maximianus, issued in 287, was interpreted to justify the death penalty. Executions took place in Germany, France, Italy, Switzerland, and Spain. A brief survey of presently known male deaths in Europe and the Americas, which number about 400, also is included. This study draws on …

Eli Lilly El-468, A New Bait Toxicant For Control Of The Red Imported Fire Ant, David F. Williams, Clifford S. Lofgren Jan 1981

Eli Lilly El-468, A New Bait Toxicant For Control Of The Red Imported Fire Ant, David F. Williams, Clifford S. Lofgren

Entomology Papers from Other Sources

Eli Lilly EL-468, a phenylenediamine, possesses the delayed-toxicity necessary for a bait toxicant to control colonies of the red imported fire ant, Solenopsis invicta Buren. In laboratory tests it gave delayed action over more than a 10-fold range of concentrations; in field tests, baits formulated on pregel defatted corn grits and applied at 20 and 40 g AI/ha produced as high as 86 and 91% control.

Thoracic Crop Formation Following Dealation By Virgin Females Of Two Species Of Solenopsis, B. M. Glancey, A. Glover, C. S. Lofgren

Entomology Papers from Other Sources

The enlargement of the esophagus following dealation to form a "thoracic" crop has been reported for Lasius queens by Janet (1907. Ducourtieux and Gout 149 p.), for queen ants of 5 genera by Petersen-Braun and Buschinger (1975. Insectes Sociaux 22: 51-66) and for mated and unmated queens of the red imported fire ant, Solenopsis invicta Buren by Glancey et al.


Comparison Of Three-Breed And Backcross Swine For Litter Productivity And Postweaning Performance , E. R. Wilson, R. K. Johnson Jan 1981

Comparison Of Three-Breed And Backcross Swine For Litter Productivity And Postweaning Performance , E. R. Wilson, R. K. Johnson

Department of Animal Science: Faculty Publications

Duroc, Hampshire and Yorkshire boars were mated with crossbred gilts of Duroc-Hampshire, Duroc-Yorkshire and Hampshire-Yorkshire breeding to produce 133 three-breed and 259 backcross litters that were farrowed during four seasons beginning in the fall of 1975. Threebreed cross litters were .31 ± .27, .57 ± .24 and .50 ± .24 pigs larger than backcross litters at birth, 21 and 42 days, respectively, and .6 ± .34, 2.3 ± 1.2 and 5.4 ± 2.4 kg heavier at these ages. The differences in average pig weight and survival percentage were small. Three-breed cross litters gained faster (.024 ± .007 kg/day) and were …


Bone Strength As A Trait For Assesing Mineralization In Swine: A Critical Review Of Techniques Involved, T. D. Crenshaw, E. R. Peo, Jr., A. J. Lewis, B. D. Moser Jan 1981

Bone Strength As A Trait For Assesing Mineralization In Swine: A Critical Review Of Techniques Involved, T. D. Crenshaw, E. R. Peo, Jr., A. J. Lewis, B. D. Moser

Department of Animal Science: Faculty Publications

Lack of standardized test procedures has resulted in considerable variation in reported values for bone strength. Such variation can be attributed in part to the type of instruments used to determine physical properties of bone, procedures used to prepare the bones for testing and equations used to calculate strength. If bone strength is to be used as a major criterion of response in mineral nutrition research, standardization of procedures for measuring and reporting bone strength is essential. Traits that describe the mechanical properties of bone as determined in the commonly used flexure test in which force is applied perpendicularly to …


Effect Of Level Of Dietary Calcium-Phosphorus During Growth And Gestation On Performance, Blood And Bone Parameters Of Swine, R. D. Nimmo, E. R. Peo, Jr., B. D. Moser, A. J. Lewis Jan 1981

Effect Of Level Of Dietary Calcium-Phosphorus During Growth And Gestation On Performance, Blood And Bone Parameters Of Swine, R. D. Nimmo, E. R. Peo, Jr., B. D. Moser, A. J. Lewis

Department of Animal Science: Faculty Publications

One-hundred and ninety-two crossbred weanling gilts (7.25 kg) were assigned to one of two treatments - (A) .65% Ca, .50% P or (B) .975% Ca, .75% P - and fed to an average weight of 92.8 kilograms. Average daily gain (.65 and .67 kg, respectively) and feed/gain were not affected by dietary treatment, but average daily feed intake was lower (P<.05) for gilts on treatment A (1.87 vs 1.95 kg).

Measures Of Racetrack Performance With Regard To Breeding Evaluation Of Trotters, M. J. Ojala, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Trotting records on the Finnish Horse were divided into two subsets: the total data set, with 13,000 race records on 554 horses by 206 sires, and the summary data set, with 1,378 records summarized annually for each horse. The purpose of the study was to determine whether these data could be utilized in a simple, yet useful way for the assessment of breeding value. A total of 24 measures of performance based on time at finish, money won and rank at finish were studied in the summary data set. The total data set included four traits compiled from records made …


Components Of Variance For Milk And Fat Yields In Dairy Goats, M. U. Iloeje, L. Dale Van Vleck, G. R. Wiggans Jan 1981

Components Of Variance For Milk And Fat Yields In Dairy Goats, M. U. Iloeje, L. Dale Van Vleck, G. R. Wiggans

Department of Animal Science: Faculty Publications

Age-season adjusted records from five breeds of dairy goats on Dairy Herd Improvement test from 1965 to 1976 were used to estimate components of variance for milk yield, fat yield, and fat percentage. The data were 6,452 Alpine, 1,730 LaMancha, 6,897 Nubian, 2,759 Saanen, and 4,007 Toggenberg lactation records. Components of variance were estimated by Henderson's Method 1 with a four-way model that included random effects of herd, year-season, sire, and doe. Herd effects accounted for 22 to 31% of the total variation in milk and fat yields and 15 to 25% of the variation in fat percentage. These effects …


Sperm Recovery From Oviducts Of Turkeys At Known Intervals After Insemination And Oviposition, M. R. Bakst Jan 1981

Sperm Recovery From Oviducts Of Turkeys At Known Intervals After Insemination And Oviposition, M. R. Bakst

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

To determine whether there is a relationship between oviposition time and the release of spermatozoa from the uterovaginal junction-sperm-host glands (UVJ-SHG),oviducal segments from turkey hens were isolated and washed immediately or 8-12 and 18-22h after oviposition on Days 1, 2, 3 and 10-13 after artificial insemination. Spermatozoa were found in nearly all segments at all times examined, indicating that sperm release from the UVJ-SHG of the turkey is probably continuous or episodic and not exclusively associated with oviposition and ovulation. Alternatively, spermatozoa may be released at specific times of the daily ovulatory cycle and ascend variable distances between the UVJ …

Mobbing Calls Of The Phainopepla, Daniel W. Leger, Laura F. Carroll Jan 1981

Mobbing Calls Of The Phainopepla, Daniel W. Leger, Laura F. Carroll

Department of Psychology: Faculty Publications

When mobbing potential predators, male Phainopeplas (Phainopepla nitens) utter smoothly upswept vocalizations, unlike the harsh, staccato mobbing calls of other birds and mammals. A Phainopepla repeats this call as it approaches the bottom of its diving arc over the predator. We suggest that these calls do not serve to attract additional mobbers to the scene. Rather, they appear to emphasize the diving attacks directed toward the predator.


Divergent Selection For In Vitro Dry Matter Digestibility In Switchgrass, K. P. Vogel, Francis A. Haskins, Herman J. Gorz Jan 1981

Divergent Selection For In Vitro Dry Matter Digestibility In Switchgrass, K. P. Vogel, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

The purposes of this study were to determine if phenotypic selection for in vitro dry matter digestibility (IVDMD) could be used to improve the IVDMD for switchgrass (Panicum virgatum L.) and to obtain heritability estimates of IVDMD in switchgrass. In 1973 a selection nursery of over 2,200 plants was established with transplanted seedlings of two similar Nebraska experimental strains. In 1974 about 800 plants that appeared to be agronomically superior were sampled for IVDMD. Single-plant selections for high and low IVDMD were made in each of the nursery rows. In 1976, ramets from 25 of the high-IVDMD selections and …


Natural And Applied Control Of Insects By Protozoa1, J.E. Henry Jan 1981

Natural And Applied Control Of Insects By Protozoa1, J.E. Henry

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Protozoa have been recognized as important factors in the natural regula­tion of the densities of certain insects. However, they have been given little consideration as applied microbial agents because entomophilic species cause chronic or debilitative infections in a narrow range of hosts. From a control standpoint, and ultimately from an economic standpoint, they could not compete with the more rapid, broad spectrum action of chemical insec­ticides or the more virulent pathogens such as bacteria, viruses, and certain fungi. Protozoa appeared useful only when low levels of pests could be tolerated, as in forests.

Gradually, interest in protozoa as potential biological …


Insecticides And Pheromones Used In The Midwest. A Short Review, Evelyn Osbourne, Paul Schwartz Jan 1981

Insecticides And Pheromones Used In The Midwest. A Short Review, Evelyn Osbourne, Paul Schwartz

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The Midwest produces most of the food and feed grains and oilseeds grown in the US. as well as a substantial proportion of a variety of other crops, but corn accounts for at least 75% of insecticide use in the region. The total amount of insecticides used on crops could be greatly reduced if economic losses from insects could be predicted accurately. We will examine the current status of chemical controls for insects of economic importance to this region, indicating some areas where new developments are needed or are likely to occur.
