G85-748 Prevention And Control Of Swine Dysentery, Gerald E. Duhamel, Alex Hogg, Barbara E. Straw

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the causes and symptoms of swine dysentery and offers management recommendations and treatment procedures for its prevention and control.

Swine dysentery is a highly contagious disease of growing and finishing pigs. First described in Indiana in 1921, it has been called black scours, bloody scours, and vibrionic dysentery.

Swine dysentery causes important financial losses because of reduced feed efficiency and lower weight gain, costs of medication and additional animal care, and death. Substantial costs may result from loss of sales of breeding stock, or depopulation when necessary. Serpula (Treponema) hyodysenteriae, a spiral bacterium, is the cause …

A series of seven short term experiments were conducted using SCWL laying hens to study liver and egg yolk cholesterol changes caused by dietary lipids. For all the experiments, the individually caged layers were 55 week-old or older and automated procedures were used to measure the liver and yolk cholesterol responses. In the first four experiments the diets contained olive or safflower oils at 8%, oleic or linoleic acids at 6%, all with or without cholesterol. In experiment 5, dietary levels of olive and safflower (1 and 8%) and cholesterol (0 and 1%) were factorially combined and examined. The olive …

An In Vitro Evaluation Of The Effect Of Bovine Viral Diarrhea Virus On Preimplantation Bovine Embryos., Charles Richard Looney

LSU Historical Dissertations and Theses

A total of 402 bovine embryos, non-surgically collected on day 6.5-7.5 after estrus, were utilized in evaluation of fluorescein diacetate (FDA) for estimating embryo viability in vitro and to investigate the effect of Bovine Viral Diarrhea (BVD) Virus on embryonic development during in vitro culture. Fluorescent assessment, using UV microscopy (440-480 nm) of embryos after staining in FDA (2.5 (mu)g/ml phosphate buffered saline: PBS), was found to be a rapid, non-toxic and accurate method for evaluation of viability. Embryos with highest fluorescent scores (Score = 4) prior to culture developed at the highest rate (95.7%), while embryos with no fluorescence …

LSU Historical Dissertations and Theses

Solution-phase pH, soluble salts, NH(,4)-N+NO(,3)-N, P and K were compared over a 140-day period in 1982 for five phosphatic sources (0-18-0, 0-46-0, 29-26-0, 18-48-0, 11-55-0) incoporated at three rates in a pine bark-sand medium (4:1 v/v). Treatment effects on visual quality of five ornamental species, media-bound and leaf-tissue nutrient levels (gardenia species) and shoot dry weights (gardenia species) were also investigated. Compared to the check, media amended with each of the P sources were generally lower in pH. Solution-phase nitrogen (NH(,4)-N+NO(,3)-N) levels for the 0-18-0 or 0-46-0 sources were significantly lower than that of the other P sources and the …

G84-723 Maximizing The Use Of Farm Strip Plots, John Havlin, Roger Wesley Elmore

University of Nebraska-Lincoln Extension: Historical Materials

Strip plots are an effective means of comparing soil and crop management practices. Guidelines are given for establishing strip plots and evaluating the results. Farmers, extension and industry personnel, and researchers have a common interest in strip plots set out on farm fields to study various soil and crop management practices. Strip plots or tests are usually designed to compare differences between tillage methods, herbicide treatments, varieties, fertilizer sources or rates, methods of chemical application, and many other crop production inputs. Strip tests established in farmer fields could satisfy wider interests, and conceivably yield more useful information, if the planners …

Virginia—Major Force In World Trade, R. Clifton Poole

Robins School of Business White Paper Series, 1980-2022

The importance of world trade has long been recognized in the Commonwealth of Virginia (VA). Indeed, one of the major reasons for establishing the original colony at Jamestown was to provide a base from which the New World "treasures" could be shipped to the mother country—England. As a result, since colonial days VA has been one of the world's major exporters of tobacco. Even today the volume of VA's tobacco exports is second only to her exports of bituminous coal.

This world trade orientation so deeply imprinted in the thinking of the early leaders of the infant colony still prevails …

Effect Of Isolated Soy Protein On The Bioavailability Of Copper In Ground Beef., James L. Smith

LSU Historical Dissertations and Theses

Test diets containing ground beef extended with 0, 10, 20 and 30% ISP were fed to Single Comb White Leghorn chicks and 28 days to determine the effect of isolated soy protein (ISP) on the availability of copper naturally present in meat. Copper content of the test diets decreased with increasing levels of ISP, ranging from 6.89 (+OR-) 0.17 ppm to 2.09 (+OR-) 0.12 ppm. Mean feed consumption per diet also decreased with increasing ISP levels as did the amount of copper consumed per bird. Although the mg copper consumed per bird decreased from diet I to diet IV, the …

Nitrification At The Rice Root., Chayong Nammuang

LSU Historical Dissertations and Theses

Nitrification at the rice root was investigated. Nitrifiers were found in the rice rhizoplane, rhizosphere and non-rhizosphere soils under flooded conditions. They were greater in the rhizoplane than in the rhizosphere soil and greatest at the heading stage of rice growth. Ammonium-sulfate or NaNO(,2) injected into the flooded soils with growing rice plants did not increase the activities of nitrifiers in the rice rhizoplane. Incubation of the flooded soil with (NH(,4))(,2)SO(,4) or NaNO(,2) did not increase the activities of NH(,4)('+)- or NO(,2)('-)-oxidizers in soils without rice. The (NH(,4))(,2)SO(,4) did not increase denitrifiers, but incubation with NaNO(,2) caused an early increase …

Bioavailability Of Iron In Beef And Beef-Soybean Mixtures., Felipe Diez

LSU Historical Dissertations and Theses

In-vivo and in-vitro studies were conducted to measure bioavailability of iron from beef and beef-soy mixtures. The effects of cooking temperature and method of cooking were investigated. Animals absorbed non-heme iron better than heme forms and utilized iron contained in beef-soy diets as efficiently as that contained in beef diets. Colorimetric iron values of 17.18, 6.0, and 9.02% were obtained in raw, broiled and microwaved beef samples, respectively. A similar trend was observed in beef-soy mixtures when analyzed raw (11.03), broiled (6.32) or microwaved (2.21). Iron contained in beef-soy flour mixtures was dialyzed in a larger proportion (16.60%) as compared …
