Differential diagnosis of nematode ova in cattle
… attention. For the past several years extension animal husbandmen and veterinarians have reported with increasing frequency parasitic infections in cattle in the State of Virginia. Hence, the Animal Husbandry Department in conjunction with the Animal Pathology Department of the Virginia …

The Illinois Pseudorabies Eradication Program and Factors Associated With Selection of Intervention Strategies and Success in Eradication
Positive autocorrelation was found to exist for the spatial distribution of quarantines among Illinois counties. This finding indicates that counties in close proximity tend to have similar numbers of herds under PrV quarantine. It was also found that space-time interaction or clustering was …

Cryptosporidium Parvum Microbial Adhesion: Interactions Between Sporozoites and Host Cells
… protozoal pathogen of both humans and animals worldwide. Since little is known about the mechanisms of attachment and invasion of C. parvum sporozoites to host cells, our goal was to elucidate the mechanism of sporozoite recognition of receptors on the host cell membrane. Knowledge of …

Evaluation of the Effectiveness of a Feline Toxoplasma Vaccine in Reducing the Exposure of Swine to Toxoplasma Gondii
The second study used a deterministic dynamic computer simulation model of the transmission of T. gondii in the swine farm ecosystem in a factorial experimental design to test the following hypotheses. T. gondii infection in finishing pigs decreases with (1) vaccination of susceptible cats, (2) …

Analysis of Porcine Immunity in PRRS Virus
… swine producers, veterinary practitioners, and animal health researchers have been economically and scientifically challenged by porcine reproductive and respiratory syndrome (PRRS). This disease is caused by a recently emerged virus of swine (PRRSV) that has been classified in the Arteriviridae …

Cardiovascular Toxicity Induced by Fumonisin in Pigs and Horses
… associated with corn intended for human and animal consumption. Since their isolation in the 1988, these toxic fungal metabolites have been shown to induce acute lethal pulmonary edema in pigs and leukoencephalomalacia in horses. The main purpose of these studies was to examine the …

Molecular Characterization of Fowlpox Virus Isolates and Evaluation of Recombinant Vaccines Generated for Protection Against Fowlpox and Reticuloendotheliosis
Fowlpox, an economically important disease of chickens, is prevented by routine immunization of birds in endemic areas with an attenuated live Fowlpox virus (FPV) vaccine. However, despite this precaution, outbreaks of Fowlpox still continue to occur in vaccinated chickens suggesting a lack of …

Neospora Caninum: Oocyst Production in Dogs, Infection of Pregnant Cows With Oocysts, and Transmission Between Wild and Domestic Animals
… is identical to N. caninum from domestic animals, indicating that transmission between wild and domestic animals is not rare. In addition, N. caninum antibodies were detected in 39% of gray wolves (Canis lupus ), 11% of coyotes, 26% of white-tailed deer, and 13% of moose ( Alces alces). …

Genetic Changes in Pseudorabies Virus After Passage in Captured, Wild Mus Musclulus Domesticus
… have been affirmed by PrV positive feral animals. Not addressing the problem of wildlife as carriers of PrV can be a problem in the eradication program. Virus carried by wild animals that migrate between farms are likely vectors for transmission of new, virulent strains. The spread of new, …

The Identification of Risk Factors for Mortality and Respiratory Disease in Lambs: An Evaluation of Risk Factor Based Health Management Strategies
The production simulation model evaluated two regression based strategies: decreased prevalence of poor milking ability (MLK) to <1% via culling over three years, and decreased prevalence of low birth weights (BWT) to 10% by improved gestational feeding. The comparison flock (BASE) had 15% poor …

On-Farm and Pre-Slaughter Management Approaches to Reducing Stress Response and Improving Pork Quality in Pigs
… capacity. For the next round of studies, an animal handling model was developed to simulate the stress incurred from pre-slaughter handling. The handling model was first used in a study that investigated the effects of Mg and handling intensity on blood acid-base balance and demonstrated that …

Use of Diaminopimelic Acid as an Internal Bacterial Marker for Estimation of the Proportion of Ileal and Fecal Nitrogen of Bacterial Origin in Dogs and Pigs
These experiments demonstrated that an appropriate bacteria rich sample can be isolated from canine and swine feces, but that more research is needed before this method can be used with ileal digesta samples. The standard N:DAPA ratios determined in these studies can be used in future research to …

Dry Period Nutrition and Hepatic Metabolism of Fatty Acids and Glucose in Transition Dairy Cows
In experiment 1, liver slices from multiparous Holstein cows on day -30, -14, 1, 14, and 28 relative to calving were used to determine the effects of far-off and close-up diets on palmitate metabolism in vitro. During the far-off period, d -60 to -25, cows received a low energy control diet fed ad …

Biochemical Characterization of a Partial Deficiency for Ump Synthase in Holstein Cattle (Enzyme, Genetic Disorder, Metabolic Defect, Hereditary Orotic Aciduria)
… biochemically. Activity is half normal in animals that are heterozygous for a potentially lethal gene. Hemolysates were used as the source of enzyme for these studies after verifying that the deficiency is generalized to all tissues. The protein product of the mutant allele for UMP synthase …

Immune Response of Swine to Porcine Reproductive and Respiratory Syndrome Virus: Laboratory and Field Studies
Porcine reproductive and respiratory syndrome virus (PRRSv) is an arterivirus that has had a significant economic impact on the pork industry in the past few decades. Our studies have focused on three major issues that concern alleviation of this problem. These include utilizing contact exposure to …

Diagnosis of Intramammary Infection by the Electrical Conductivity of Milk
This study consisted of two experiments. In the first, quarter samples of foremilk, primary milk, and strippings were obtained from twelve cows after 3, 6, 9, 12, and 15 h milking intervals.

Analysis of T-2 Toxin in Feed and Animal Specimens
A gas liquid chromatographic method was developed for the determination of T-2 toxin in feeds. The T-2 toxin was extracted from feeds with aqueous methanol. A zinc acetate and aluminum chloride solution was used to denature and precipitate proteinaceous compounds, plant pigments and other …
