Relationships Between Rate Of Growth, Catheptic Enzymes And Meat Palatability In Young Bulls, Chris R. Calkins, S. C. Seideman, J. D. Crouse
Department of Animal Science: Faculty Publications
Relationships between rate of growth, endogenous muscle enzymes and meat palatability were investigated in 48 young (13 mo) Angus bulls. After backgrounding for 4 mo, bulls were placed on a high-energy diet for 30 d, at which time they were assigned randomly to one of three feeding treatments: 1) high energy (ad libitum-fed), 2) maintenance energy (restriction-fed to maintain body weight) or 3) sub-maintenance energy (restriction-fed to lose .68 kg/d). Cattle were slaughtered after 30 or 60 d on trial. Cathepsins B and H and β-glucuronidase in the longissimus muscle were quantitated at slaughter. Serum hydroxyproline, longissimus muscle collagen, taste-panel …

Influence Of Picolinic Acid On The Uptake Of Zinc-Amino Acid Complexes By The Everted Rat Gut, D. A. Hill, E. R. Peo, Jr., A. J. Lewis
Department of Animal Science: Faculty Publications
Three hundred fifty rats were used in three experiments to: 1) validate the everted gut procedure as an in vitro technique for estimating Zn absorption, 2) determine the effect of increasing ratios of picolinic acid (PA) to Zn on Zn absorption and 3) determine the effect of PA on absorption of Zn and amino acid complexes at pH 6, 7 and 8.
Importance Of Predation By Adult Trout On Mortality Rates Of Fingerling Rainbow Trout Stocked In East Canyon Reservoir, Utah, Wayne A. Wurtsbaugh
Importance Of Predation By Adult Trout On Mortality Rates Of Fingerling Rainbow Trout Stocked In East Canyon Reservoir, Utah, Wayne A. Wurtsbaugh
Watershed Sciences Faculty Publications
Personnel from Utah State University, working in cooperation with the Utah Division of Wildlife Resources and the Utah Cooperative Fish and Wildlife Research Unit, are attempting to determine various sources of mortality of fingerling rainbow trout (Salmo gairdneri) stocked into mid-elevation reservoirs in the State. Returns of planted fish are often much below desired levels. Angler surveys indicate that in East Canyon Reservoir, fishermen harvest only about 30% of the fingerling trout stocked, and this is a much higher return than in many other waters.

Effects Of Blue Tilapia/Channel Catfish Polyculture On Production, Food Conversion, Water Quality And Channel Catfish Off-Flavor, Les Torrans, Fran Lowell
Journal of the Arkansas Academy of Science
Channel catfish (Ictalurus punctatus) monoculture ponds stocked with 10,000/ha of mixed- size catfish were compared to ponds stocked additionally with blue tilapia (Tilapia aurea). Ponds stocked with 5000/ha young-of-the-year blue tilapia produced 236 kg/ha less catfish, but tilapia biomass increased by 1020 kg/ha, averaging 233 g/fish. Ponds stocked with sexually mature tilapia in Aprilto provide forage to the catfish had increased catfish production but a poorer food conversion radio. Ponds stocked with sexually mature tilapia in June or July had catfish production and FCR's similar to the controls. Dissolved oxygen was significantly lower than the controls in all polyculture treatments. …

Validation Of The Otolith Increment Aging Technique For Striped Bass, Morone Saxatilis, Larvae Reared Under Suboptimal Feeding Conditions, Cynthia Jones, Edward B. Brothers
Validation Of The Otolith Increment Aging Technique For Striped Bass, Morone Saxatilis, Larvae Reared Under Suboptimal Feeding Conditions, Cynthia Jones, Edward B. Brothers
OES Faculty Publications
Striped bass, Morone saxatilis, larvae were reared in the laboratory for 97 days to validate the otolith increment aging technique for this species. Otolith-increment deposition rates were determined under optimal laboratory conditions for growth and under three conditions of restricted feeding and using both light and scanning electron microscopy (SEM). Under optimal laboratory conditions. increments were deposited daily from the fourth day after hatching through the first 2 months of life and were discernible with the light microscope. For larvae reared under restricted feeding regimes and readings done with the light microscope, counts did not reflect true age. Counts …

Pharmacy Faculty Articles and Research
The primary structure of the hemoglobins from Jaguar (Panthera onco) are presented. Electrophoretic separations without and with a dissociating agent revealed the presence of two hemoglobin components, OL2ß\ and a2 02. The separation of the hemoglobin components was achieved by ion-exchange chromatography. The globin chains were separated by ion-exchange chromatography and also by reversed phase HPLC. The amino-acid sequences of the native chains and peptides were determined by liquid-phase and gas-phase sequencing. N-Acetylserine was detected by FAB-mass spectroscopy as N-terminal group of the ßl chain. The sequences are compared with that of human hemoglobin (Hb A).

The Computer As A Collection Management Tool, Suzanne B. Mclaren, Hugh H. Genoways, Duane A. Schlitter
University of Nebraska State Museum: Mammalogy Papers
Since the mid-1960s, discussion of computer use for information retrieval in museum collections has usually focused on research potential. Much attention has been given to the idea of networking and the ability to access data across great distances. However, the potential for collection management usage has also proven to be a legitimate rationale for computerization. Numerous aspects of collection management are discussed for which the computer may be employed. Topics include creating cross-reference files, updating taxonomic and geographic information, pinpointing mismatched specimens, locating lost and uncataloged material, controlling loan procedures, producing accession files for insurance purposes, curating all or part …
Growth And Proteolytic Activity Of Selected Psychrotrophic Bacteria In Whole Milk And Whole Milk Retentate, Ravinder Reddy
Growth And Proteolytic Activity Of Selected Psychrotrophic Bacteria In Whole Milk And Whole Milk Retentate, Ravinder Reddy
Electronic Theses and Dissertations
In the last twenty years a number of membrane separation processes have evolved from laboratory scale, through pilot plant investigation, to full scale production units. One such process, ultrafiltration, has been found particularly useful in the dairy industry. Ultrafiltration uses porous polymeric membranes to separate molecules, principally on the basis of their molecular weight. In milk, fat, protein and associated substances are retained on the membrane. Permeate, which passes through the membrane contains mainly water, lactose and other low molecular weight substances. There is interest in ultrafiltration of milk because of it is potential importance in saving costs to both …
Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr.
Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr.
Journal of the Arkansas Academy of Science
The United States government established a trading house at Arkansas Post in 1805 on the north bank of the Arkansas River in the newly purchased Louisiana Territory. The goal of this trading house was to foster good relations with the Quapaw tribe and other indigenous peoples. John B. Treat and his successors operated the post and meticulously recorded the number, value, and species of pelts traded. Tabulation of these records, which have been preserved in the National Archives, revealed that 9 or 10 species contributed a total of about 44,000 hides, worth approximately $18,000. White-tailed deer (Odocoileus virginianus) pelts comprised …

The Identification Of The Threatened Southeastern Shrew Using Multivariate Statistical Techniques, Thomas M. Padgett, Roger K. Everton, Robert K. Rose
The Identification Of The Threatened Southeastern Shrew Using Multivariate Statistical Techniques, Thomas M. Padgett, Roger K. Everton, Robert K. Rose
Biological Sciences Faculty Publications
The threatened subspecies of the southeastern shrew, Sorex longirostris fisheri, is endemic to the Great Dismal Swamp of southeastern Virginia. Previous studies based on discriminant analysis of external measurements determined that intergrades with the upland form, Sorex l. longirostris, exist along the periphery of the Swamp. To better discriminate among these populations, a study of cranial morphology was initiated. Fifteen cranial measurements were taken, using 59 specimens of Sorex collected previously form southeastern Virginia, including the Dismal Swamp. Both Principal Component and Cluster Analyses revealed no significant cranial variation or morphometric patterns within the specimens examined, but a …

Distribution And Current Status Of The Threatened Dismal Swamp Southeastern Shrew, Sorex Longirostris Fisheri, Robert K. Rose, Roger K. Everton, Thomas M. Padgett
Biological Sciences Faculty Publications
The Dismal Swamp southeastern shrew, Sorex longirostris fisheri, was given "Threatened" status by the U.S. Fish and Wildlife Service in 1986 because of its limited distribution and the potential threat of interbreeding with the nearby upland subspecies, Sorex l. longirostris. Known from about 20 specimens collected before 1980 and a few dozen taken since then, "fisheri" seems to have morphologically diverged from the smaller upland "longirostris" in association with the development of the Dismal Swamp. The detection of southeastern shrews that are intermediate in size between the two subspecies, coupled with the location of these collection sites on …
Morphological Variation, Karyology, And Systematic Relationships Of Heteromys Gaumeri (Rodentia: Heteromyidae), Mark D. Engstrom, Hugh H. Genoways, Priscilla K. Tucker
Morphological Variation, Karyology, And Systematic Relationships Of Heteromys Gaumeri (Rodentia: Heteromyidae), Mark D. Engstrom, Hugh H. Genoways, Priscilla K. Tucker
University of Nebraska State Museum: Mammalogy Papers
Morphological variation was assessed within and among populations of Heteromys gaumeri using univariate and multivariate statistical analyses of external and cranial measurements. Although patterns and amount of nongeographic variation in H. gaumeri were similar to other heteromyines, geographic variation was relatively conservative. Mean values of most characters were statistically homogeneous among localities and spatially unpatterned. Consequently, no association was found between levels of within- and among-sample variation for individual characters (the "Kluge-Kerfoot phenomenon"). Populations of H. gaumeri were chromosomally monomorphic. The lack of morphological and chromosomal variation in H. gaumeri contrasts sharply with patterns in other heteromyines. Heteromys gaumeri is …
Chickpeas As A Protein And Energy Supplement For High Producing Dairy Cows, Darryl Lynn Hadsell
Chickpeas As A Protein And Energy Supplement For High Producing Dairy Cows, Darryl Lynn Hadsell
Electronic Theses and Dissertations
Thirty lactating Holstein cows were randomly assigned to one of three diets to evaluate chickpeas as a dietary supplement from wk 4 to 16 postpartum. Diets contained chickpeas at 0, 50, and 100 % of the concentrate dry matter in place of corn and soybean meal. Total mixed diets, fed individually, contained concentrate corn silage and alfalfa hay at 52, 32, and 16 % of the dry matter. Milk yield (34.5, 35.1, 35.7 kg/d) was higher for cows fed 100 % chickpeas than 0 % chickpeas. Fat (3.06, 3.09, 3.28 %) was highest for cows fed 100 % chickpeas. Milk …
