Effect Of Dietary Lactose On Gain, Feed Conversion, Blood, Bone And Intestinal Parameters In Postweaning Rats And Swine, R. L. Moser, E. R. Peo, Jr., T. D. Crenshaw, P. J. Cunningham

Department of Animal Science: Faculty Publications

Two trials were conducted to determine the effect of lactose on performance, bone integrity and certain blood constituents in post-weaning rats and swine. The effect of lactose on calcium and phosphorus and percentage ash content of the small intestine was also determined. In both trials, average daily gains were not influenced by the feeding of diets containing 30% lactose. Feed conversion was depressed in both rats and pigs when 30% lactose was fed.

Potential Of Utilizing Scrap Processed Cheese As A Major Ration Component For Channel Catfish, Calvin J. Haskins, Scott H. Newton

Journal of the Arkansas Academy of Science

Three cages (0.9 m³) were stocked with 200 channel catfish, Ictalurus punctatus Rafinesque, fingerlings (73.7 g avg.) in a 1.5 hectare pond. Two cheese rations were formulated and fed to the catfish; the first consisting of cheese, oil, and vitamin C (C + VC)and the second consisting of cheese, cottonseed meal, oil, trace minerals, and vitamins (CC + VM). A commercial trout ration (TC) was fed as a control. High mortalities occurred in the C + VC diet, thus resulting in premature removal of that cage from the study (after 86 days). A sample of 50 fish from the two …

Evaluation Of A Full-Fat Soybean Ration For Channel Catfish Production In Cages, Scott H. Newton, Walter R. Robison, Calvin J. Haskins

Journal of the Arkansas Academy of Science

An experimental ration consisting of 50% full-fat soybeans, heated 170°C, was compared to a commercial trout chow in a 120-day feeding trial using two stocks of channel catfish, Ictalurus punctatus Rafinesque. Catfish were reared in 0.9 m³ floating cages, with 200 fish per cage, anchored in a 1.5 hectare farm pond. A Central Arkansas stock significantly outperformed a Southeast Arkansas stock for comparisons of net production and food conversion efficiency (FCE), with 92% greater production and 41% better FCE, respectively. Survival was 90% or greater for all fish. There was no significant difference in dress-out weight between the stocks. However, …

Psychopharmacological Analysis Of Central Muscarinic And Nicotinic Receptors, Leonard T. Meltzer

Theses and Dissertations

Arecoline and nicotine are two psychoactive cholinergic alkaloids. Arecoline is primarily a muscarinic agonist while nicotine, at low doses, is a nicotinic agonist. The experiments in this dissertation investigated two major areas: (1) the role of different factors in the development of tolerance to the behavioral effects of arecoline and nicotine, and (2) the possible mechanism and site of action of the discriminative stimulus (DS) effects of arecoline and nicotine.

The role of dispositional and physiological factors comfiared to behavioral factors in the development of tolerance to the effects of arecoline and nicotine on operant behavior was assessed in Experiments …

Duration Of Antibiotic Residues In Milk From Cows Treated Via Intrauterine And Intramammary Infusion, Elias Abdurahman

Electronic Theses and Dissertations

Antibiotics have been employed by farmers and veterinarians for treatment of infectious cattle diseases for over 3 decades. The most common of these diseases in dairy cows is mastitis. Mastitis is defined by the National Mastitis Council (NMC) (49) as an inflammation of the mammary gland. It is the most prevalent and most costly disease .of dairy cattle. It is estimated that at least 50% of all cows are infected with some form of mastitis at any one time in one or more quarters; cows in the average herd contract clinical mastitis one and one-half times per yr (49) which …

Heat-Treated Soybean Proteins For Lactating Dairy Cattle, Clayton D. Mielke

Electronic Theses and Dissertations

The value of heat treatment of protein supplements to reduce protein solubility and increase protein utilization was studied in two lactation trials. Experiment I was designed to study the utilization of heat-treated soybean meal (HSBM) by cows in early lactation. An extrusion process with moist heat was used to produce HSBM - a product with lower protein solubility than regular soybean meal (SBM). Ten cows, 3 wks post-partum, were assigned to treatments of HSBM or SBM. Due to a problem in feed bag labeling the concentrate mix containing SBM and corn was not as formulated. A large amount of ground …

Feeding Value Of High Protein Oat Silage Versus Corn Silage For Dairy Cows, Tilahun Sahlu

Electronic Theses and Dissertations

Corn accounts for 80% of the total silage production in the United States while oats ranks second as a feed grain crop. Oats are a major crop in areas of the world where temperatures are cool and short growing seasons are not well suited for corn production. South Dakota is the leading oat producing state in the nation with 1. 68 million kilograms of oats produced annually. Oats play an important roll as animal feed because among common cereals in the United States it ranks highest in both protein and lysine content. Due to the wide genetic diversity of oat …

The Relationship Of Food Conversion Efficiency And Growth Potential In Juvenile Mosquitofish, Gambusia Affinis, Joseph J. Cech Jr., Michael J. Massingill, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

New information concerning respiratory metabolic rates of juvenile mosquitofish (i = 915 mg 02 kg-1 h-1 at 20° C) was applied to existing data on mosquitofish respiration and combined with findings on growth and food consumption rates to determine percentages of net ingested energy used for growth and respiration over a 10- 35° C temperature range. The energy percentage used by mosquitofish for respiration was minimized at 25-30° C while that used for growth (= food conversion efficiency) was maximized at the same temperature. A calculated growth potential index, derived from an overall energy balance equation, was also maximized at …

The Effects Of Fin Clipping And Tagging On Growth And Behavior Of The Largemouth Bass (Micropterus Salmoides), Daniel M. Daley

Masters Theses

One hundred largemouth bass, ranging in size from 148mm to 385mm, were equally divided into four treatment groups (control, tag only, tag and left pectoral fin clip, and tag and all paired fins clipped) , and placed into a 5.56 hectare pond on 22 May and 25 May 1979. Upon recovery on 28 September 1979, the increase in length from the time of most recent annulus formation was found to be significantly greater in Age I control fish (x̄ = 125mm) than in fish of the same age in the other three treatment groups (x̄ = 110mm, 103mm, and 106mm, …

The Influence Of Atrazine (2-Chloro-4-(Ethylamino)-6-(Isopropylamino-S-Triazine) On The Severity Of Gibberella Zeae-Induced Seedling Blight Of Corn, Louis A. Heaton

Masters Theses

Three corn inbreds were grown in artificially inoculated, steamed greenhouse soil amended with atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine) to determine the herbicide's effect on the severity of Gibberella zeae (Schwabe) Petch-induced seedling blight. Corn inbreds used were Gibberella-resistant (FR632), Gibberella-intermediate (FRMo17), and Gibberella-susceptible (C123^HT). Soils were amended with atrazine at rates of 2, 15, and 30 ppm.

Susceptible inbred seedlings showed no response to the herbicide with symptims equally severe in controls and all 3 concentrations of atrazine. Intermediate inbred seedlings grown in all atrazine amended soils showed significantly more severe disease symptoms than controls. Soil amended with …

A Test Of The Fertilizing Value And Inhibitory Qualities Of Sewage Sludge, Gregory D. Kugler

Masters Theses

Three sludges - aerobic, anaerobic, Milorganite, and peat moss were tested for fertilizing ability, seed inhibition, and chemical composition. Using green bean (Phaseolus sp.) and rye grass (Lolium perenne) seeds in two sludge amended soils, a greenhouse study indicated growth enhancement for the rye grass and variable results for the green beans. Algal and fungal contaminations were problems. Seeds germinated in sludge extract were inhibited, but no correlation with the chemical analyses could be established. Only Milorganite had a heavy metal content significantly higher than the soils tested.

The Effect Of Walk Or Jog Recovery From Anaerobic Work On Blood Lactate Levels And Subsequent Two-Minute Run Performance, Rick Alan Livesey

Masters Theses

The purpose of the study was to investigate the effects of a walk or jog recovery on two-minute run performances and the concentrations of blood lactate.

Eight highly trained male subjects were selected from the Eastern Illinois University Track Team. The test procedure consisted of two, maximal two-minute runs on the track for distance, separated by a 30-minute recovery. The recovery consisted of a walk at 20-minutes per mile pace or a jog at 7½ to 8 minutes per mile pace. Venous blood samples were drawn three minutes after the first run, two minutes prior to the second run, and …

Comparative Effects Of Two Avoidance Paradigms Upon Ethanol Self-Selection, Richard O. Shellenberger Ii

Twelve adult male rats were given free access to a two bottle free-selection of tap water or a 10% ethanol/tap water solution in the home cage for a period of 140 consecutive days with the alcohol consumption data in the form of mg absolute ETOH/g subject weight collected daily. This study incorporated three stages. Phase I was a 40 day period of alcohol acclimation with alcohol consumption during the second 20 days constituting the baseline consumption rate. Mean baseline alcohol consumption was used to block subjects into three groups. The second phase of the study consisted of an 80 day …

Repopulation Of Fishes In Riley Creek, Coles County, Illinois Following Nitrogen Fertilizer Pollution, Kim James Carney

Masters Theses

The repopulation of stream fishes was studied from 17 May 1979 to 25 October 1979 following a major kill (100% mortality) caused by nitrogen fertilizer pollution in Riley Creek, Coles County, Illinois. The extent of recovery was determined by comparing post-kill collections with pre-kill survey data that was collected on 25 October 1978.

Repopulation began six days after the abatement of the pollution source. It is suggested that the initial source of repopulation was from the nearest undamaged tributary. The first three reinhabitants in order of appearence were: stonerollers (Campostoma anomalum); creek chubs (Semotilus atromaculatus); and …

A Search For Lymphatic Tissue In The Mouse Pineal Gland, John B. Hutchinson

Masters Theses

There is recent evidence that the pineal gland in some species may have lymphatic qualities during early post natal life. In this study the development and structure of the pineal complex in the CDF₁ mouse is examined in fetal, neonatal, juvenile, and adult stages. The gland appears as an out growth of the dorsal wall of the third ventricle of the brain and at ten days gestation attains a mean size of 90 microns in the transverse and 35 microns in the median saggital plane. General and specific staining shows fetal and early post partum tissue to be compact …

Comparative Reproduction Of The Red-Eared Turtle, Pseudemys Scripta Elegans, In Heated And Natural Lakes, Gary Marshal Thornhill

Masters Theses

The effect of heating on aquatic ecosystems by energy producing power plants has not been fully determined. A comparative study of the reproduction of Pseudemys scripta was conducted in heated and natural lakes in southwestern Illinois from 30 March to 10 July, 1979. Lakes used were the same as those used for comparative growth studies of P. scripta by another researcher. Lake Baldwin (heated) has had a reduction in vegetation since that researcher's work. Temperatures were taken of air, water surface, and one meter deep.

Turtles were caught by hand, trammel nets, and in carp-baited hoop nets. Captured turtles were …

An Examination Of The Red Blood Cell Alloantigentic System In The Chinese Hamster, Kathryn Elliget Blashfield

Masters Theses

This research was done to determine whether any ABH-like blood group system was present in Chinese hamsters (Cricetulus griseus). The population of animals included 35 hamsters, 20 "normal" or outbred (10 males; 10 females) and 15 diabetic from The Upjohn Company's colony of inbred diabetic animals (8 males; 7 females; BE and BA lines). Animal sera and erythrocytes were compared by: hyperimmunization of rabbits (10 New Zealand White) with hamster erythrocytes; screening hamster erythrocytes and plasmas with human blood diagnostic typing antisera (Ortho Diagnostics), anti-H lectin, anti-A₁ lectin and human red cells of various types; absorption and elution of …
