G92-1112 Lice Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Identifying and controlling lice on cattle both are covered here.

Cattle lice may be the most underestimated livestock insect in terms of economic losses. The USDA estimates that U.S. livestock producers lose $125 million a year to cattle lice.

Heavy louse populations cause lowered milk production, loss of flesh, stunted growth, general unthriftiness and anemia. "Chronic" or "carrier" cows may abort due to louse-induced anemia. During severe winters, louse-infested animals are more susceptible to respiratory diseases.

G92-1093 Use Of Animal Drugs In Livestock Management, Duane N. Rice, Barbara E. Straw

University of Nebraska-Lincoln Extension: Historical Materials

How to handle antibiotics and other drugs to prevent residues in meat while maintaining an effective animal health program.

Use of animal drugs in food animal production must be accepted as a responsibility rather than a right when trying to improve animal health. Drugs should be used to enhance a health program and not as a substitute for good management.

Disease prevention is based on good nutritional and environmental factors, sanitation, and the use of a complete herd health program. Use of vaccines for common diseases and in some cases segregation or culling of infected animals is important. Good management …

G92-1070 Feeding Dairy Cattle For Proper Body Condition Score, Rick Grant, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes feeding and management practices that allow the producer to control body condition throughout lactation and the dry period.

Body condition score is a critical measure of a dairy feeding system's effectiveness. Adequate body fat reserves promote milk production, reproductive efficiency, and herd longevity. Excessively fat cows or overly thin cows run much greater risks of metabolic problems, lower milk yield, poor conception rates, and dystocia (difficult calving). Failure to attain proper body condition or rapid changes in body condition score during early lactation may indicate problems in herd health or feeding management.

Nf92-73 Nutrition And The Athlete: Fueling Your Sport, Linda S. Boeckner

University of Nebraska-Lincoln Extension: Historical Materials

Increased activity brought on by participating in workouts, training or competition requires extra energy intake. Dietary plans that provide the most efficient energy sources will help to fuel the athlete for success. A diet built around high levels of complex carbohydrates protein intake is the best approach.

G92-1111 Mineral And Vitamin Nutrition Of Dairy Cattle, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide focuses on the best sources of minerals and vitamins, current requirements for production, and feeding practices to best meet these requirements and promote health and productivity of dairy cattle. Dairy cattle require at least 17 minerals and three vitamins in their diet for optimal milk production, reproductive performance, and herd health. Although classical mineral or vitamin deficiency symptoms are rare, in many cases under- and overfeeding of certain minerals and vitamins does occur. Even small imbalances or deficiencies can develop into reproductive, health, and milk production problems. As herd milk production averages in Nebraska climb, it will become …

Wobbler Syndrome In Horses, Equine Section, Department Of Animal Sciences, University Of Kentucky

Agriculture and Natural Resources Publications

Wobbler Syndrome refers to a number of disease states in the horse. The most common is termed cervical vertebral malformation (CVM) and is characterized by malformation or compression of the spinal cord which leads to spasticity, ataxia, and incoordination. These symptoms are caused by damage to or compression on the spinal cord.

Cervical vertebral instability (CVI) and cervical static stenosis (CSS) are the two distinct types of CVM. CVI causes dynamic spinal cord compression. It typically affects horses from 4-12 months of age. CSS typically affects horses between 12-36 months of age and is characterized by a closing of the …

Exogenous Progesterone And Progestins As Used In Estrous Synchrony Regimens Do Not Mimic The Corpus Luteum In Regulation Of Luteinizing Hormone And 17Β-Estradiol In Circulation Of Cows, N. Kojima, T. T. Stumpf, Andrea S. Cupp, L. A. Werth, M. S. Roberson, M. W. Wolfe, Roger J. Kittok, James E. Kinder

Department of Animal Science: Faculty Publications

Our working hypothesis was that the low concentrations of progesterone (P₄) and synthetic progestins administered in hormonal regimens to control estrous cycles of cows would have similar effects on secretion of LH and 17β-estradiol (E₂). In addition, we hypothesized that concentrations of exogenous P₄ typical of the midluteal phase of the estrous cycle and the corpus luteum (CL) would have similar effects on LH and E₂, and the effects would be different from those of synthetic progestins and low concentrations of P₄. Cows (n = 29) were randomly assigned to one …

Chloroplast Heteroplasmicity Is Stabilized By An Amber-Suppressor Tryptophan TrnaCua, Weizhu Yu, Robert J. Spreitzer

Department of Biochemistry: Faculty Publications

Photosynthesis-deficient mutants of the green alga Chlamydomonas reinhardtii were previously shown to arise from nonsense mutations within the chloroplast rbcL gene, which encodes the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (EC 4.1.1.39). Photosynthesiscompetent revertants of these nonsense mutants have often been found to be stably heteroplasmic, giving rise to both mutant and revertant cells during mitotic or meiotic divisions under nonselective growth conditions. It was proposed that the stable heteroplasmicity might arise from a balanced polymorphism of suppressor and wild-type alleles of a tRNA gene maintained within the polyploid chloroplast genome. In the present study, we have focused on determining the …

A Biosystematic Study Of Panus Conchatus (Basidiomycetes; Agaricales), James Edward Johnson

Masters Theses

As part of a biosystematic study of Panus conchatus (Bull.: Fr.) Fr., North American and European herbarium specimens from the Field Museum and the University of Michigan were examined and a description of the taxon prepared. Tissue and single spore isolates were obtained from basidiocarps collected in Illinois. Single and polyspore isolates were obtained from a collection made in Switzerland by R. H. Petersen. Culture mat analyses were completed on several media and the taxonomic value of cultural characters assessed. Based on this study, the identification of somatic cultures by cultural characteristics is unlikely. Single spore isolates from the Illinois …

Leakage Of Solutes From Imbibing Seeds Of Supersweet Corn Cultivars That Differ In Tolerance To Low Germination Temperatures, Linda Kull

Masters Theses

Supersweet types of sweet corn (Zea mays L. var rugosa) with shrunken-2 endosperm are preferred by consumers because of their extra sweetness and postharvest retention of good flavor. However, their acceptance by growers is hindered due to reduced field emergence, especially in cold soils. This reduced emergence is related to seed quality. To examine differences between supersweet corn cultivars which are tolerant and sensitive to low temperatures, two cultivars were chosen based on their emergence in the field at low temperatures (10-15 C). 'Illini Gold' was chosen as the tolerant cultivar and 'Honey'n'Pearl' as the sensitive cultivar. Seeds …

Parasitology As An Interpretive Tool In Archaeology, Karl J. Reinhard

Karl Reinhard Publications

Parasitological studies of archaeological sites can be used to interpret past behavior and living conditions. During the 1980s problem-oriented research into prehistoric- and historical-period parasitism developed and resulted in thefield of archaeoparasitology. Archaeoparasitology attempts to integrate parasite data into archaeological theory and interpretation. Within the last decade, four major archaeoparasitological laboratories emerged. They developed interpretive frameworks that apply parasitological data to a remarkable variety of prehistoric behaviors. Parasite remains can be used to reconstruct aspects of diet, health, and other behaviors such as transhumance and trade. Finally. analysis of the distribution of parasite remains can be used to interpret aspects …

Population Recovery Of The Whooping Crane With Emphasis On Reintroduction Efforts: Past And Future, David H. Ellis, James C. Lewis, George F. Gee, Dwight G. Smith

Proceedings of the North American Crane Workshop

The U.S. Fish and Wildlife Service (USFWS) began building a captive whooping crane (Grus americana) colony at Patuxent Wildlife Research Center (patuxent), Maryland, in 1966. From 1976 to 1984, 73 eggs from this colony and 216 eggs from Wood Buffalo National Park (Wood Buffalo), Canada, nests were placed in sandhill crane (G. canadensis) nests at Grays Lake National Wildlife Refuge (Grays Lake), Idaho, the site of the first whooping crane reintroduction attempt. Although 84 chicks fledged from the 289 eggs, the egg transfer program has been discontinued because of inordinately high mortality (only ca. 13 birds remain …

Food And Feeding Habits Of Released Florida Sandhill Cranes, Christine R. Rucker

Proceedings of the North American Crane Workshop

Food habits of 4 pairs of free-ranging Florida sandhill cranes (Grus canadensis pratensis) on St. Catherine's Island, Georgia, were studied from May to October 1990. Food items were identified and quantified at close range « 10 m). The 4 pairs varied in how they used plant and animal resources (P < 0.0001). Animal material in the diets averaged 19.1 % and ranged from 13.4 to 36.7%. Plant material averaged 80.9% in the pairs' diets. Major foods included subsurface bulbs, roots, and tubers of yellow star grass (Hypoxis micrantha), catbrier (Smilax glauca), and false garlic (Allium bivalva), longleaf pine seeds (Pinus palustris), and insects. Food habits shifted seasonally for all pairs (P < 0.(001). In July and August the percent occurrences of yellow star grass and false garlic in the diets were > 50 %. During September and October pine seed occurrence was > 75 % in the diets of …

The slopes ofleast squares regression lines relating EWL to Qva at different temperatures were not significantly different and averaged -0.50mg H20·m-3 ·g-2 ·h-1 (range: -0.39 to -0.61). Increased Qva restricted EWL in C. anna more than has been reported for …

Effects Of Salinity On Survival And Growth Of Postlarval Penaeus Vannamei, John T. Ogle, Kathy Beaugez, Jeffrey M. Lotz

Gulf and Caribbean Research

Eight and 22-day-old Penaeus vannamei postlarvae were exposed to several salinities for 24 hours and 120 hours by direct transfer from 32 ppt salinity to lower salinity waters. The challenge study included six experiments conducted on 8-day-old postlarvae (PL-8) and five experiments conducted on 22-day-old postlarvae (PL-22). Each experiment consisted of ten replicates of ten animals each. Shrimp were held in 1 L plastic containers with 500-ml of seawater. Lowered salinity resulted in lower survival for shrimp of both ages. Longer exposure time resulted in lower survival for shrimp of both ages. Younger shrimp exhibited lower survival than older shrimp. …
