All Current Publications
Most of us have felt that injections given to a calf early in its life would be of little problem by the time it went to slaughter. We were WRONG!!! Colorado State University has provided the data and the pictures to prove it. In fact, 90% of the lesions found at slaughter originated during the cow-calf, stocker or early feeding periods. And, injections given while the calf is young caused greater lesions than those given when it was older. The study followed calves injected at branding or weaning and found a high incidence of lesions and blemishes when they went …
Copper Deficiency In Utah, Clell Bagley, Norris Stenquist, Dennis Worwood
Copper Deficiency In Utah, Clell Bagley, Norris Stenquist, Dennis Worwood
All Current Publications
Copper deficiency has been diagnosed in a number of Utah cattle herds, yet few producers use copper supplements. Cattle deficient in the element can suffer significant production losses. Producers need to balance both the effects and the costs of copper supplements. Too much copper can cause copper toxicity or poisoning. And adding copper may not be economical if animals are only marginally deficient. Further, the deficiency may occur only on specific feeds or pastures, correcting itself when cattle are moved.

Halogeton Toxicity In Cattle, Clell Bagley
All Current Publications
“Everyone” knows that halogeton is toxic to sheep, but sometimes we forget that it is also toxic for cattle. If cattle eat enough of it, it will kill them. One autumn incident resulted in the death of over 40 head of cows in a multiple owner grazing herd.

Controlling Internal Parasites In Utah Cattle, Clell Bagley
All Current Publications
Most cattle harbor some internal parasites (worms) and Utah cattle are no exception. The varied geographic and climatic conditions of Utah allow for tremendous variation in the parasite burden of different cattle herds. The numbers of parasites varies from very few to so numerous as to cause severe weakness and even death of cattle.
Disease Resistance In Cattle, Clell Bagley
Disease Resistance In Cattle, Clell Bagley
All Current Publications
The ability of cattle to resist the many disease processes to which they are exposed is truly amazing. And yet, when several adverse factors combine, this resistance can be overcome and result in a herd disaster which is just as amazing. This discussion will be broken down into four major areas. But it is the combined functioning of all four areas that actually provides disease resistance.

Infectious Cattle Diseases And Vaccines, Clell Bagley
All Current Publications
Vaccines are available for 20 to 30 infectious diseases of cattle. With the various brand names and different combinations available, the choice of vaccines can become very complicated. Calves vaccinated under 6 months of age should generally be re-vaccinated again after that age to provide a longer lasting immunity.

Weak Calf Syndrome Or Bvd Fetal Infection, Clell Bagley
All Current Publications
A serious health problem of newborn calves was recognized 20 years ago and termed “weak calf syndrome”(WCS). The Bovine Virus Diarrhea (BVD) virus was often isolated from affected calves and from these herds. In recent years, veterinarians have again been looking at the effects of the BVD virus on the fetus.

A great deal of money and effort have been expended over the years to find methods for control of mastitis in dairy cows. Both European and U.S. workers have developed programs of prevention that are very similar. These preventive programs require implementation of the seven basic procedures outlined below. It has been shown repeatedly that this programs works.

If the flock is lambed on the range, assistance is not given to individual ewes. Catching those needing help causes so much disruption of ewes with normal lambs and results in so many orphans, it is detrimental. One of the primary advantages of shed lambing a range flock is being able to better assist during birth and those first crucial hours of life.

Validation Study Of A Novel Neonatal Pneumotach, Scott A. Kofoed
Utah Space Grant Consortium
We have developed a pneumotach for measuring respiratory gas flows in humans and or animals. The pneumotach enables the monitoring of respiratory and metabolic function in human subjects over extended periods of time. A bench study was conducted to validate the new pneumotach system against other predicate devices. The pneumotach under test compared well to the predicate devices used.

The Role Of Alfalfa Weevil Larvae As Prey In Adult Maintenance And Reproduction By Two Ladybird Beetle Species, Douglas R. Richards
The Role Of Alfalfa Weevil Larvae As Prey In Adult Maintenance And Reproduction By Two Ladybird Beetle Species, Douglas R. Richards
Biology
Ladybird beetles (Coccinella spp.) are important predators of pea aphids (Acyrthosiphon pisum) in alfalfa. Adult ladybird beetles also consume alternative foods such as alfalfa weevil larvae (Hypera postica) and nectar. I compared egg production and ovariole condition of Coccinella septempunctata (an Old World species introduced to North America) and Coccinella transversoguttata (an indigenous North American species) that were maintained on diets of pea aphids, alfalfa weevil larvae, sugar water ("artificial nectar"), or various combinations of these foods. In the first experiment, gravid females of both species continued to lay many eggs and had large ovarioles …
Discovery, Identification, And Evaluation Of Antifungal Compounds Produced By Pseudomonas Syringae, Kevin N. Sorensen
Discovery, Identification, And Evaluation Of Antifungal Compounds Produced By Pseudomonas Syringae, Kevin N. Sorensen
Biology
New antifungal agents are needed to combat the increasing incidence of fungal diseases. Strains of Pseudomonas syringae produce cyclic lipodepsinonapeptides (CLPs) such as syringomycin, syringostatin, and syringotoxin, which could be developed as therapeutic antifungal agents. Of these CLPs, syringostatin has been difficult to produce in vitro. Syringostatin production was achieved using syringomycin minimal medium supplemented with arbutin and D-fructose, and a high cell density. Syringostatin A (SS-A) was purified in quantities sufficient to evaluate its antifungal activities. The antifungal activities and erythrocyte toxicities of syringomycin E (SR-E), SS-A, and syringotoxin B (ST-B) were evaluated. All showed fungicidal activities against most …
Wildfire Case Study: Butte City Fire, Southeastern Idaho, July 1, 1994, Bret W. Butler, Timothy D. Reynolds, United States Department Of Agriculture, Forest Service, Intermountain Research Station
Wildfire Case Study: Butte City Fire, Southeastern Idaho, July 1, 1994, Bret W. Butler, Timothy D. Reynolds, United States Department Of Agriculture, Forest Service, Intermountain Research Station
All U.S. Government Documents (Utah Regional Depository)
The Butte City Fire occurred on July 1, 1994, west of Idaho Falls, ID. Ignited from a burning flat tire, the blaze was driven by high winds that caused it to cover over 20,500 acres in just over 6.5 hours. Sagebrush (Artemisia tridentata ssp. wyomingensis) is the principal shrub species of this high dese~t rangeland. With the absence of vegetation after the fire, erosion increased tremendously. Because the fire occurred on the Idaho National Engineering Laboratory, researchers were able to gather weather information from remote meteorological stations positioned on and around the site.

A Study Of The Immune Effects Of Orally Ingested Ginseng Combined With Moderate High-Intensity Exercise In Mouse And Human Subjects, Gordon Hunter Pedersen
A Study Of The Immune Effects Of Orally Ingested Ginseng Combined With Moderate High-Intensity Exercise In Mouse And Human Subjects, Gordon Hunter Pedersen
Biology
Ginseng, an extract of the Panax ginseng plant, and exercise producing a heart rate of 82.5% of maximum were studied alone and in combination for effects on certain immune parameters in mice and young adult humans, and on development of cytomegalovirus (CMV) disease in mice. A motorized treadmill was used in the mouse experiments, with a clinical pulse oximeter adapted to monitor heart rates and arterial oxygen saturation (SaO2). Compared to infected controls whose death rate was 60%, orally administered ginseng (250 mg/kg/day) beginning 48 hours pre-CMV inoculation caused a 25% survivor increase. Exercise (six repetitions of running …
Polar Distribution Of Neurofilaments In A Nonspiking Central Nervous System Neuron, David Dale Cole
Polar Distribution Of Neurofilaments In A Nonspiking Central Nervous System Neuron, David Dale Cole
Biology
Immunolabelling of phosphorylated and nonphosphorylated neurofilaments in teleost retinal horizontal cells, which are nonspiking neurons, is described. Light microscopy (postembedding immunolabelling) of retinal tissue sections revealed nonphosphorylated neurofilaments localized to regions where horizontal cell axon terminals, dendrites, and somata are located. In contrast, phosphoneurofilaments were localized to regions where axons and axon terminals of various retinal neurons, including horizontal cells, are found, as in typical spiking central nervous system neurons. Electron microscopy (preembedding immunolabelling) demonstrated that phosphoneurofilaments were localized to cone horizontal cell axons and axon terminals. Immunolabelling of primary cell cultures, however, revealed that axon-specific distribution of phosphoneurofilaments in …
Effects Of Plant Architecture On The Foraging Behavior And Prey Capture Success Of Two Generalist Predators Attacking The Russian Wheat Aphid, Teresa L. Clark
Effects Of Plant Architecture On The Foraging Behavior And Prey Capture Success Of Two Generalist Predators Attacking The Russian Wheat Aphid, Teresa L. Clark
Biology
This research investigated the effects of plant architecture on the foraging behavior and prey capture success of two generalist predators of the Russian wheat aphid, Diuraphis noxia (Mordvilko). One study examined plant architectural effects on the behavior of a native predator, the common green lacewing, Chrysoperla plorabunda Fitch; a second study examined host plant effects on larvae and adults of the fourteen-spotted ladybird beetle, Propylea quatuordecimpunctata (L.), which is native to Eurasia and has been released in the United States for potential control of D. noxia. Behavioral observations of each of these predators were conducted on two architecturally diverse …
Hnk-1 Immunoreactivity In In Situ Adult Teleost Retina, Kie Hoon Jung
Hnk-1 Immunoreactivity In In Situ Adult Teleost Retina, Kie Hoon Jung
Biology
To identify HNK-1 bearing molecules, anti-HNK-1 was used to probe adult hybrid bass retina, including mature, central retina and the circumferential germinal margin (CGM), where new cells are constantly added to the neural circuitry. The HNK-1 antigen was heavily distributed in both of the plexiform (synaptic) layers, in tufts of Müller cell microvilli at the outer limiting membrane, throughout the optic fiber layer, and in tubular processes surrounding cone horizontal cells in the inner nuclear layer. A differential fixation scheme suggested that the Müller cell microvillar and tubular process HNK-1 immunoreactivity was due primarily to glycoproteins, with the remainder possibly …
Hybrid Bass Retinal Cells In Situ And In Vitro: Structure And Immunocytochemistry, Kyeongsuk Ki
Hybrid Bass Retinal Cells In Situ And In Vitro: Structure And Immunocytochemistry, Kyeongsuk Ki
Biology
The morphologies of intact retina and acutely isolated retinal neurons are described for a relatively newcomer model for studies of visual physiology, the hybrid bass (Morone chrysops x M. saxatilus). These features are indistinguishable from the white bass (M. chrysops) at the light microscopic level. In situ immunolocalization patterns for several glial and neuronal markers also match previous work in the white bass. Carbonic anhydrase is found in retinal layers corresponding to Müller (glial) cells and horizontal cells; glial fibrillary acidic protein (GFAP) and glutamine synthetase are found in Müller cells only; and the intermediate M, …
Secondary Reproductive Strategies Of The Eastern Kingbird (Tyrannus Tyrannus), Assessed By Dna Fingerprinting And Egg Physiognomy, Diane L. Rowe
Secondary Reproductive Strategies Of The Eastern Kingbird (Tyrannus Tyrannus), Assessed By Dna Fingerprinting And Egg Physiognomy, Diane L. Rowe
Biology
Extra-pair fertilization, a secondary breeding strategy, was detected in the eastern kingbird (Tyrannus tyrannus) using multi-locus DNA fingerprinting. I assessed the genetic parentage of 20 broods in a population of kingbirds in central New York. Two DNA probes were used to test for exclusion of nestlings as true offspring of one or both social parents. Band-sharing coefficients and the number of novel bands were used to discern which parent was not a first-degree relative of the nestling in question. No cases of conspecific brood parasitism or quasi-parasitism were documented. However, extra-pair paternity was found to be very common, …
