Effect Of Mineral Deficiency On The Growth Of The Salt Marsh Rush Juncus Roemerianus, Lionel N. Eleuterius, John D. Caldwell Jan 1981

Effect Of Mineral Deficiency On The Growth Of The Salt Marsh Rush Juncus Roemerianus, Lionel N. Eleuterius, John D. Caldwell

Gulf and Caribbean Research

Plants of the salt marsh rush Juncus roemerianus were grown in deficient and complete nutrient solutions, and the growth responses were compared qualitatively and quantitatively. Plants grown in solutions deficient in K, S, P, and Mg were similar in appearance, which exemplified severe growth retardation. Plants grown in solutions deficient in Ca, N, and Fe also were very similar in total growth response, but had much longer leaves, more shoots, and greater biomass than those grown in the K, S, P, and Mg deficient solutions. Plants grown in complete nutrient solutions, with various sources of Fe, were very robust. Growth …


Silica And Ash In Several Marsh Plants, F.C. Lanning, Lionel N. Eleuterius Jan 1981

Silica And Ash In Several Marsh Plants, F.C. Lanning, Lionel N. Eleuterius

Gulf and Caribbean Research

Ash and silica content and their depositional patterns in tissues of Spartina alterniflora Loisel., Distichlis spicata (L.) Greene, Scirpus validus Vahl., Zizania aquatica L., and Limonium carolinianum (Walt.) Britt. were determined. Zizania aquatica leaves had the highest silica content (6.0%) of any of the plant parts tested; silica making up over half of the ash. Silica in the plants was opaline in character. Limonium carolinianum did not accumulate silica in any great amount. However, ash content was very high in Limonium carolinianum and Scirpus validus making up over 17% of the dry weight of the leaves. X-ray diffraction showed the …


Preliminary Observations Of The Effect Of Eimeria Funduli (Protozoa: Eimeriidae) On The Gulf Killifish Fundulus Grandis And Its Potential Impact On The Killifish Bait Industry, Mobashir A. Solangi, John T. Ogle Jan 1981

Preliminary Observations Of The Effect Of Eimeria Funduli (Protozoa: Eimeriidae) On The Gulf Killifish Fundulus Grandis And Its Potential Impact On The Killifish Bait Industry, Mobashir A. Solangi, John T. Ogle

Gulf and Caribbean Research

Liver infections of Eimeria funduli, a pathogenic coccidium, greatly affected growth of Fundulus grandis (Gulf killifish) maintained in an aquaculture facility for 55 days. At termination of the experiment, average weight gained by uninfected killifish was 877.5% compared to 308.0% in diseased fish. There appeared to be no correlation between mortality and disease in this study.


G81-574 Reproductive Diseases In Cattle, Duane Rice Jan 1981

G81-574 Reproductive Diseases In Cattle, Duane Rice

University of Nebraska-Lincoln Extension: Historical Materials

The reproductive diseases mentioned in this NebGuide comprise some of the more common problems confronting the cattle industry today.

Although many advances have been made in controlling reproductive diseases in cattle, serious losses are still common. These losses can be reduced by recognizing the diseases and following the proper management recommendations that are available today. Nearly 50 percent of reproductive failure in cattle is due to infectious diseases, and there are vaccines available that can prevent some of these. Management recommendations may include: 1) vaccines, 2) general sanitation, 3) artificial insemination (AI) or, if a problem is already present, 4) …

Heg81-145 The Cut Up Chicken, Part I, Daniel E. Bigbee

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide shows how to cut a chicken carcass into breast with ribs, wings, thighs with back, and drumsticks. You can save from 5 to 10 cents per pound if you cut up your own broiler-fryer chickens. There are two basic ways of cutting the chicken carcass. This guide shows how to cut the carcass into breast with ribs, wings, thighs with back, and drumsticks. The Cut Up Chicken, Part II, HEG 81-146, shows how to cut these parts with the ribs and back as separate pieces.


Bacterial Gill Disease Of Freshwater Fishes, S. F. Snieszko Jan 1981

Bacterial Gill Disease Of Freshwater Fishes, S. F. Snieszko

United States Fish and Wildlife Service: Publications

Bacterial gill disease (BGD) was first described by Davis (1926, 1927), who observed it in fry and fingerling brook trout (Salvelinus fontinalis) and rainbow trout (Salmo gairdneri) in hatcheries in Vermont. The affected trout were kept in dirt-bottom ponds and were not crowded; , daily mortalities were very low. Mortalities rapidly increased when the water temperature increased and diminished when the temperature decreased. Examination of the diseased trout revealed clubbing of gill filaments. In microscopic examination of wet mounts of the filaments" Davis found that the gill surface was covered with closely adhering strands of long, …


Heat Tolerance Of Kentucky Bluegrasses, Perennial Ryegrasses, And Annual Bluegrass, David J. Wehner, T. L. Watschke Jan 1981

Heat Tolerance Of Kentucky Bluegrasses, Perennial Ryegrasses, And Annual Bluegrass, David J. Wehner, T. L. Watschke

Office of the Dean (CAFES) Scholarship

Use of cool-season turfgrasses in transitional environments is limited, in part, by their heat tolerance. Development of a rapid heat tolerance screening technique would be of value in determining the potential of turf•grasses for use in warmer areas.

The heat tolerance of 22 Kentucky bluegrass (Poa pratensis L.) cultivars, Poa annua L., and four perennial ryegrass cultivars (Lolium perenne L.) was evaluated by exposing plants for 30 min to temperatures ranging from 41 to 49 C in single degree intervals. Ten-week-old plants, which had been grown under a low level of N fertilization and watered infrequently to maximize …


Influence Of Phosphate Source On Vesicular-Arbuscular Mycorrhizae Of Bouteloua Gracilis, Michael F. Allen, James C. Sexton, Thomas S. Moore Jr., Martha Christensen Jan 1981

Influence Of Phosphate Source On Vesicular-Arbuscular Mycorrhizae Of Bouteloua Gracilis, Michael F. Allen, James C. Sexton, Thomas S. Moore Jr., Martha Christensen

Department of Plant Pathology: Faculty Publications

Non-mycorrhizal and vesicular-arbuscular mycorrhizal Bouteloua gracilis infected with Glomus fasciculatus were grown in defined media containing different phosphate sources and compared with respect to phosphate content and form, biomass, chlorophyll concentration, and root phosphatase activity. The phosphate sources were sodium monobasic phosphate, a mixture of sodium monobasic phosphate and calcium phytate, and calcium phytate. Inositol and inositol plus calcium were added to the sodium phosphate medium as additional treatments. Mycorrhizal infection was highest in roots of plants grown in the presence of phytate (75%). Lower root infection levels were noted in plants from the sodium phosphate (19%) and mixed phosphate …


Breeding And Use Of Nonhuman Primates In The Usa, Joe R. Held Jan 1981

Breeding And Use Of Nonhuman Primates In The Usa, Joe R. Held

International Journal for the Study of Animal Problems

Several species of nonhuman primates, each possessing specific characteristics of particular value, are used by the United States biomedical community in various health-related activities. These animals are man's closest relatives and are indispensable in understanding and controlling human health problems. The destruction of primate habitats and embargoes on the export of primates from source countries have decreased the supply of these animals. The inadequate and erratic supply of these resources threatens the continuation of many ongoing and new activities contributing to improving human health. In the U.S., a program has been developed to meet the health needs of primates:

The Buller-Steer Syndrome, Richarad Ulbrich Jan 1981

The Buller-Steer Syndrome, Richarad Ulbrich

International Journal for the Study of Animal Problems

Bulling among steers is an abnormal behavioral trait and is a common health and economic problem in feedlot operations. Factors associated with the buller-steer syndrome are hormonal implantation, seasonality and environmental conditions, stress, overcrowding, and social interaction between individuals. Research has examined relationships between these and other factors and buller occurrence. Boredom of feedlot cattle may contribute more to buller occurrence and other undesirable behavior than we might suspect. Research is needed to determine the feasibility of enriching the environment of penned livestock in general, the goal of which would be, in theory, eliminating undesirable behavior and increasing performance.


Productivity And Farm Animal Welfare, Michael W. Fox Jan 1981

Productivity And Farm Animal Welfare, Michael W. Fox

International Journal for the Study of Animal Problems

In the search for and debate over objective indices of farm animal welfare, productivity Is regarded by many animal scientists and others in the livestock industry as the most reliable measure of an animal's overall well-being and adaptability. On the surface, this would seem so, as productivity, in terms of growth rate, milk yield, feed conversion, and egg production, can be easily quantified. However, there are flaws in this assumption.

Equine Behavior Problems In Relation To Humane Management, Katherine A. Houpt Jan 1981

Equine Behavior Problems In Relation To Humane Management, Katherine A. Houpt

Equines Collection

The behavior problems of horses are frequently related to management practices. Behaviors that are termed stall vices appear to be either stereotyped behaviors that occur in reaction to stress, or patterns that emerge when natural behaviors such as grazing are prevented. The behavior cases presented to the New York State College of Veterinary Medicine, Cornell University, were tabulated: 27% were stall vices and 27% were some form of aggression. The stall vices were circling, digging, kicking the stall, chewing wood, swallowing air or self-mutilation. Management of horses on pasture rather than in stalls prevents the development of many of these …


The Role And Responsibility Of Zoos: An Animal Protection Viewpoint, John E. Cooper Jan 1981

The Role And Responsibility Of Zoos: An Animal Protection Viewpoint, John E. Cooper

Zoos and Aquariums Collection

The aim of this paper is to look at zoological collections from the viewpoint of the animal and, in particular, to draw attention to areas where welfare considerations should be paramount. I do not intend to cover the capture and transportation of zoo animals, although this is obviously of great importance and must be included in any overall consideration of the welfare of zoo animals. In this paper, however, I shall concentrate upon the care of the animal within the zoo environment.

Ec81-1869 Guide To The Identification Of Physiological Disorders Of Landscape Plants, John E. Watkins, Donald H. Steinegger Jan 1981

Ec81-1869 Guide To The Identification Of Physiological Disorders Of Landscape Plants, John E. Watkins, Donald H. Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Physiological disorders are plant diseases caused by non-living agents. Other terms for this group of disorders are abiotic diseases or noninfectious diseases.

Physiological disorders are often confused with pathogen-caused diseases but they do not spread from plant to plant as do diseases caused by living organisms. Landscape plants are often exposed to toxic materials, mechanical damage, nutritional stress, homeowner neglect and other stress factors in the urban environment.

This 4-color extension publication highlights the following physiological disorders of landscape plants: sun scald, drought, lightning injury, winter injury, root girdling, iron chlorosis, salt injury, herbicide injury and air pollution.

The Membrane Polypeptides Of The Vacuolar System: Composition And Recycling, William A. Muller Jan 1981

The Membrane Polypeptides Of The Vacuolar System: Composition And Recycling, William A. Muller

Student Theses and Dissertations

A method has been developed to deliver an iodinating system into the confines of the phagolysosome, allowing us to study the nature of the phagolysosomal membrane. Lactoperoxidase (LPO) is covalently coupled to carboxylated latex spheres (LPO-latex) in a stable enzymatically active form. The addition of LPO-Iatex to cultured macrophages leads to their rapid attachment, ingestion, and enclosure in a plasma membranederived phagocytic vacuole. These organelles rapidly fuse with preexisting lysosomes and are converted to phagolysosomes (PL) that demonstrate both acid phosphatase and lactoperoxidase activities. The exposure of LPO-Iatex containing cells to 125I- and an extracellular peroxide-generating system, glucose …

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.
