Physiological Reactions Of Poultry To Heat Stress And Methods To Reduce Its Effects On Poultry Production, Narongsak Chaiyabutr Jun 2004

Physiological Reactions Of Poultry To Heat Stress And Methods To Reduce Its Effects On Poultry Production, Narongsak Chaiyabutr

The Thai Journal of Veterinary Medicine

Thermal environment is regarded as the prime factor governing the production because, both the feed consumption and heat production are related closely to the thermal environment. Therefore, heat stress is caused by a combination of environmental and animal factors that result in reduced performance as the animal attempts to cool itself. In this review, the physiological reactions of bodily functions during heat exposure in poultry are described. Thermal panting, the marked response of poultry to heat stress, is compensatory behavior to permit a high rate of evaporative cooling from the respiratory tract. Cardiorespiratory responses to thermal stress show different patterns …

The Estimation Of Glomerular Filtration Rates Using Endogenous Creatinine Clearance In Nine Dogs, Chollada Buranakarl, Wanchai Yenpetch, Siram Suvarnavibhaja Jun 2004

The Estimation Of Glomerular Filtration Rates Using Endogenous Creatinine Clearance In Nine Dogs, Chollada Buranakarl, Wanchai Yenpetch, Siram Suvarnavibhaja

The Thai Journal of Veterinary Medicine

The objective of this study was to estimate the glomerular filtration rates of normal dogs using the clearance of endogenous creatinine, and comparing it to the clearance of exogenous creatinine. Nine healthy dogs, of both sexes, were used in this study. The results showed a significant relationship, with a correlation coefficient = 0.714 (p<0.05). The regression line was an endogenous creatinine clearance = (-0.803 + 0.677) x exogenous creatinine clearance. The use of endogenous creatinine clearance is a simple and convenient method without the need to administer any substances and can be used to evaluate renal function in clinical practice.

The Function Of The Oviduct In Relation To Sperm Transport And Capacitation In Swine, Paisan Tienthai Jun 2004

The Function Of The Oviduct In Relation To Sperm Transport And Capacitation In Swine, Paisan Tienthai

The Thai Journal of Veterinary Medicine

In the pig, sperm transport is regulated, to facilitate normal fertilization of the ovulated oocytes, by the oviduct which contains a particular segment, the sperm reservoir. The main function of the sperm reservoir is to ensure that stored spermatozoa have maintained viability and fertilizing capacity. The process of sperm capacitation is delayed in the sperm reservoir, during the lengthy pre-ovulatory estrus by interactions between the spermatozoa, the oviduct epithelium and secretion products. Sperm capacitation seems to be facilitated by the tubal fluid in the upper segment of the oviduct releasing sperm from the reservoir in relation to the time of …

Rabies In Newfoundland & Labrador May 2004

Rabies In Newfoundland & Labrador

Zoonotics and Wildlife Disease: Publications

Rabies is a deadly viral disease of the brain spread by the bite of infected mammals. It is most commonly seen in red or arctic foxes in this province though other wild animals such as bats may carry the disease. Sick foxes can bite other foxes, dogs, cats, wolves, caribou, other animals and people and make them sick. Once bitten by an animal with rabies it can take from two weeks to six months before the animal shows signs of the disease. Though uncommon, this period can be as short as 4 days or as long as a year or …

Identification Of A Novel Bovine Herpesvirus 1 Transcript Containing A Small Open Reading Frame That Is Expressed In Trigeminal Ganglia Of Latently Infected Cattle, Melissa Inman, Joe Zhou, Heather Webb, Clinton J. Jones May 2004

Identification Of A Novel Bovine Herpesvirus 1 Transcript Containing A Small Open Reading Frame That Is Expressed In Trigeminal Ganglia Of Latently Infected Cattle, Melissa Inman, Joe Zhou, Heather Webb, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine herpesvirus 1 (BHV-1), like other Alphaherpesvirinae subfamily members, establishes latency in sensory neurons. The latency-related (LR) RNA is abundantly expressed during latency, and expression of an LR protein is required for the latency reactivation cycle in cattle. Within LR promoter sequences, a 135-aminoacid open reading frame (ORF) was identified, ORF-E, that is antisense to the LR RNA. ORF-E is also downstream of the gene encoding the major viral transcriptional activator, bICP0. Strand-specific reverse transcription-PCR demonstrated that a transcript containing ORF-E was consistently expressed in trigeminal ganglia (TG) of latently infected calves, productively infected cultured cells, and acutely infected calves. …

“French Heartworm” Infection Of Dogs & Foxes In Newfoundland Apr 2004

“French Heartworm” Infection Of Dogs & Foxes In Newfoundland

Zoonotics and Wildlife Disease: Publications

French Heartworm is the common name for a parasitic disease affecting foxes, dogs, and other members of the dog family. Caused by the nematode (worm) Angiostrongylus vasorum, this disease was first thought to exist in France in the mid 1800's. It is now considered to exist generally in Europe but has not been reported in North America other than on the Island of Newfoundland, with the exception of infected animals imported from Europe but diagnosed in North America. The first case recorded in Newfoundland was in Aquaforte (Avalon Peninsula) in 1973.

Chronic Wasting Disease—Prion Disease In The Wild, Steve Bunk Apr 2004

Chronic Wasting Disease—Prion Disease In The Wild, Steve Bunk

Zoonotics and Wildlife Disease: Publications

In 1967, mule deer in a research facility near Fort Collins, Colorado, in the United States apparently began to react badly to their captivity. At least, that was the guess of researchers working on the natural history and nutrition of the deer, which became listless and showed signs of depressed mood, hanging their heads and lowering their ears. They lost appetite and weight. Then they died—of emaciation, pneumonia, and other complications—or were euthanized. The scientists dubbed it chronic wasting disease (CWD), and for years they thought it might be caused by stress, nutritional deficiencies, or poisoning. A decade later, CWD …

Genomically Intact Endogenous Feline Leukemia Viruses Of Recent Origin, Alfred L. Roca, Jill Pecon-Slattery, Stephen J. O'Brien Apr 2004

Genomically Intact Endogenous Feline Leukemia Viruses Of Recent Origin, Alfred L. Roca, Jill Pecon-Slattery, Stephen J. O'Brien

Biology Faculty Articles

We isolated and sequenced two complete endogenous feline leukemia viruses (enFeLVs), designated enFeLV-AGTT and enFeLV-GGAG. In enFeLV-AGTT, the open reading frames are reminiscent of a functioning FeLV genome, and the 5′ and 3′ long terminal repeat sequences are identical. Neither endogenous provirus is genetically fixed in cats but polymorphic, with 8.9 and 15.2% prevalence for enFeLV-AGTT and enFeLV-GGAG, respectively, among a survey of domestic cats. Neither provirus was found in the genomes of related species of the Felis genus, previously shown to harbor enFeLVs. The absence of mutational divergence, polymorphic incidence in cats, and absence in related species suggest that …
