The Taxonomy And Relationships Of The Northern Swans, Paul A. Johnsgard

Paul Johnsgard Collection

The recent (1972) publication of the Wildfowl Trust's book The Swans has brought together an unprecedented array of information on all of the swans of the world, and makes it desirable to raise once again the question: how many species of northern swans are there, and what are their evolutionary relationships to one another? Delacour (1954) suggested the comprehensive vernacular name 'northern swans' to distinguish 'the various knobless white swans which breed in or near the Arctic parts of the northern hemisphere' from the Mute Swan (Cygnus olor) and the three southern hemisphere swans. The northern swans have …

Diurnal Rhythm In Serum Testosterone Levels And Thymidine Uptake By Testes In The Domestic Fowl, B. D. Schanbacher, W. R. Gomes, N. L. Vandemark

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

Serum testosterone levels were measured by radioimmunoassay at 3-hr. intervals in a total of 80 mature Dwarf Leghorn cocks, and incorporation of thymidine-³H in testes was measured by radioautography in an additional 24 birds. Serum testosterone was higher at night (P< 0.02), averaging 7.14 ± 0.55 ng/ml during light hours (0900-1800 hr.), and 9.42 ± 0.73 ng/ml (P < 0.02) during darkness (2100-0600 hr.). In a second experiment to determine the rate of incorporation of thymidine into testes, birds were inadvertently subject to continuous artificial light during the 24-hr. study period; uptake of thyrnidine-³H did not differ between day and nighttime periods, averaging 174 ± 5 and 177 ± 4 tritium-labeled cells per mm², respectively. These data suggest that, during the Ohio spring season, testosterone production is favored at night. Spermatogenic DNA production may not vary diurnally, but the unusual lighting scheme involved may have altered the …

Influence Of Nutritional Regime On Age At Puberty In Gilts, P. J. Cunningham, C. H. Nabor, Dwane R. Zimmerman, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Age at puberty was determined for 205 Gene Pool gilts; 68 fed a 10% protein diet (HLC) consisting of high-lysine corn, minerals and vitamins and 137 fed a 14% protein corn soybeam meal diet (CS). Gilts fed the CS diet reached puberty 18.7 days earlier than gilts fed the HLC diet. Use of post-weaning daily gain as a covariable reduced the difference between diets to 9 days. The pooled within diet regression of age at puberty on post-weaning gain was -22.75 days per kilogram. The correlation between pubertal age and daily gain was significantly higher on the HLC diet (-.30 …

G74-189 Growing Dahlias, Don Steinegger, John E. Watkins, Frederick P. Baxendale

University of Nebraska-Lincoln Extension: Historical Materials

Propagation, culture, diseases, and insects of dahlias are covered here.

The dahlia is a versatile flowering plant, providing a wide array of sizes, forms and colors. Flowers range from half-inch pompons to giants. Flower forms vary from daisy-shaped singles to fully double types with intermediate forms, such as anemone.

Dahlia cultivars which flower the first year from seed are referred to as annuals. Many of these annuals form tuberous roots the first year. These tuberous roots can be saved for use next year.

G74-142 Harvesting And Preserving Hay Crop Silage, Rick Grant, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes principles of successful hay crop harvest, silage preservation, management techniques to obtain high quality hay crop silage, and proper use of silage storage facilities.

Most hay (legume and grass) crops can be ensiled, or made into silage, successfully. For best feeding value and preservation, consider the special requirements for ensiling each crop.

Hays to be ensiled should be selected on the basis of economics. Which are the most profitable for supplying nutrients? For example, legumes have a relatively higher value for dairy herds than for beef finishing operations because of dairy cows' higher requirement for protein.

G74-149 Bloat Prevention And Treatment (Revised July 1996), Dale Grotelueschen, Richard J. Rasby, Don Hudson, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Bloat is a form of indigestion marked by an excessive accumulation of gas in the rumen. Immediately after cattle consume a meal, the digestive process creates gases in the rumen. Most of the gases are eliminated by eructation (belching). Any interruption of this normal gas elimination results in gas accumulation or bloat.

This NebGuide discusses the types of bloat which may occur in cattle and methods to prevent and treat bloat.

G74-125 Oats In Swine Diets (Revised December 1981), Ernest R. Peo, Donald B. Hudman, Mike Brumm

University of Nebraska-Lincoln Extension: Historical Materials

Oats are not considered a standard feed grain in swine diets in Nebraska because of the small acreage planted. However, oats can be used by all ages of swine with some limitations. The feeding value of oats is 80 percent that of corn. With proper formulation, limiting the amount of oats in diets will cause no reduction in swine performance. The nutritive content of a feed grain is the primary factor in determining its use. This NebGuide discusses the processing of oats for swine diets, gestation diets, lactating diets, starter diets, and growing-finishing diet.

G74-154 Mosquito Control Guide (Revised 1974), John B. Campbell, David L. Keith, W. Kramer

University of Nebraska-Lincoln Extension: Historical Materials

Mosquitoes are insects belonging to the order Diptera. Although there are some 50 species of mosquitoes in Nebraska, fewer than a dozen are important.

This NebGuide discusses the life cycle, control and impact of mosquitoes common to Nebraska.

Blood And Tissue Identification Of Selected Birds And Mammals, Part 1, David W. Oates, Craig W. Brown, Debra L. Weigel

Other Publications in Wildlife Management

Identification of blood and tissue samples for law enforcement purposes was initiated in 1968 by Carl Wolfe, Senior Biologist, Research Division, Nebraska Game and Parks Commission. At that time and up to the present, a great deal of assistance, time and advice has been received from Carl R. Jolliff, Director of the Clinical Laboratory of Lincoln; Dr. Connell L. Marsh, Professor of Biochemistry, University of Nebraska, and Dr. Leonard W. Staudinger, Chairman of Biology Department, Nebraska Wesleyan University. Grateful appreciation is extended to Dr. Stan Cassel DVM and all Game Commission personnel of Nebraska and South Dakota who aided in …

G74-100 Feeding High Moisture Corn, Terry L. Mader, Paul Q. Guyer, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

In recent years the use of high moisture grain has become more popular due to the increased costs of handling and dry feed grains. For cattle feeders in particular, storing grains as high moisture is one practice that can improve their competitive position and reduce costs. Using high moisture grains allows greater opportunity to design a system that will minimize harvest, storage and feed processing costs.

Grains such as sorghum and wheat have been stored as high moisture, but corn is the principal high moisture grain stored. High moisture corn can be processed and stored as whole shelled corn, ground …

G74-149 Bloat Prevention And Treatment, Rick Stock, Richard J. Rasby, Duane Rice

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the types of bloat which may occur in cattle and methods to prevent and treat bloat.

Bloat is a form of indigestion marked by an excessive accumulation of gas in the rumen. Immediately after cattle consume a meal, the digestive process creates gases in the rumen. Most of the gases are eliminated by eructation (belching). Gases that are trapped and not eructated may form a foam or froth in the rumen which further prevents their elimination. Froth formation can be caused by many factors resulting from interactions between the animal, rumen microorganisms, and differences in plant biochemistry.

G74-136 Grain Sorghum Processing For Beef Cattle, Rick Stock, Terry L. Mader

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the feeding value of grain sorghum relative to corn and various grain processing methods for grain sorghum.

It has been widely recognized that grain sorghum (milo) must be processed to be efficiently used by finishing cattle. Grain sorghum shows more improved utilization from processing than corn, wheat and barley. Dry ground or rolled grain sorghum has a relative feeding value of 85% to 95% (avg 90%) of dry rolled corn. Processing grain sorghum by more sophisticated methods (early harvesting, steam-flaking, etc.) greatly enhances its feeding value.

Chemical composition suggests that there should be less difference in the …

G74-170 Nitrates In Livestock Feeding, Richard J. Rasby, Rick Stock, Bruce Anderson, Norman R. Schneider

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes symptoms, causes, prevention and treatment of nitrate poisoning in livestock.

Nitrate poisoning in cattle occurred long before the use of nitrogen fertilizers. In the late 1800s there were reports of cornstalk poisoning in Nebraska, and nitrate poisoning from oat hay in North and South Dakota and from weeds in the high-organic matter soils in Florida and Wisconsin.

Nitrate concentrations in feeds for livestock depends more on plant species and environmental conditions prior to harvest than on the amount of available nitrogen in the soil.

Effect Of Dietary Calcium And Phosphorus Level Upon Calcium, Phosphorus And Nitrogen Balance In Swine, P. E. Vipperman, Jr., E. R. Peo, Jr., P. J. Cunningham

Department of Animal Science: Faculty Publications

Three metabolism trials were conducted to determine the effects of dietary calcium and phosphorus level upon calcium, phosphorus and nitrogen balance in growing swine. The nine pigs in each trial averaged 22.6, 25.2 and 26.5 kg initially for trials 1, 2 and 3, respectively. The diets contained three levels of calcium and three levels of phosphorus and were rotated among the pigs in the three trials. Feed intake was adjusted to metabolic size.

Comparative Studies Of Socialization, Patricia Draper

Department of Anthropology: Faculty Publications

This paper will not attempt a comprehensive review of the recent literature on socialization. Rather, it will deal with four areas of the comparative study of childhood which have particular interest to this writer: systematic ethnographic reports on child life in non-Western societies; education and anthropology; cognitive style and socialization; and socialization for sex role. As a further means of narrowing the potential range of this review, the author will exclude most reports of infant, adolescent, and adult socialization.

Advantages In Mathematically Weighting Waterfowl Food Habits Data, George A. Swanson, Gary L. Krapu, James C. Bartonek, Jerome R. Serie, Douglas H. Johnson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The relative importance of various foods occurring in the diet of blue-winged teal (Anas discors), pintail (A. acuta), and gadwall (A. strepera) breeding in south-central North Dakota and lesser scaup (Aythya affinis) breeding in the vicinity of Great Slave Lake, Northwest Territories, are com- pared by the aggregate volume and aggregate percent methods. Advantages of the aggregate percent method are discussed in relation to the information presented.

Survival Mechanisms Of Phytopathogenic Bacteria, M. L. Schuster, D. P. Coyne

Department of Plant Pathology: Faculty Publications

Natural habitats usually do not provide bacteria the continuity of agricultural crops. With continuous culture. perpetuation of pathogen is no problem. Although agricul­ tural practices provide some discontinuity between crops. it is less than that in nature. Uniformity of crop germ plasm also favors inoculum buildup and perhaps perpetuation of the pathogens.

Developmental Changes In Spermatogenesis, Testicular Carnitine Acetyltransferase Activity And Serum Testosterone In The Ram, B. D. Schanbacher, W. R. Gomes, N. L. Vandemark

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

Total of 73 crossbred rams was used to determine spermatogenic and steroidogenic changes in the testis of the growing animal. Testicular weight increased slowly until 80 days of age, then increased tenfold during the following 3 months. Spermatogenesis began in rams at 60 to 70 days of age and was qualitatively complete by 120 days. Although testicular levels of the enzyme carnitine acetyltransferase (CAT) increased in growing rams, CAT did not appear to be uniquely associated with any particular cell type. Therefore, this enzyme was judged to be unsatisfactory as a cell "marker" in studying spermatogenesis in this species. Serum …

Recollections, George W. Beadle

Department of Biochemistry: Faculty Publications

In these exciting times when elementary and high schools teach modern biology, including many of the intricacies of biochemical genetics, the long slow process by which our present knowledge in this area was gained is not often fully appreciated. A third of a century elapsed before Mendel’s work was "rediscovered" and properly appreciated. Archibald E. Garrod’s (1) prophetic appreciation of the relation genetics and biochemistry, beginning soon after the so-called rediscovery of Mendel, lay fallow for more than forty years despite the fact that he published widely and relatively voluminously. As late as a quarter of a century after the …

The Effect Of Simultaneous And Sequential Presentation Of Stimulus Dimensions On Absolute Judgment Accuracy, John H. Flowers

Department of Psychology: Faculty Publications

The effects of spatial stimulus repetition, sequential stimulus repetition, spatially separated dimensional redundancy, and sequentially presented dimensional redundancy on absolute judgment accuracy of hue and brightness were compared. Two exposure durations, 0.1 and 2.0 sec, were used. While spatial repetition did not improve accuracy for either dimension, the sequential repetition of brightness produced a small increase in accuracy. The spatial presentation of correlated values of both dimensions increased accuracy only at the 2.0-sec duration. The sequential presentation of both dimensions increased accuracy, but only at the 2.0-sec duration was this gain substantial and greater than that provided by the sequential …
