Artificial Breeding Of Large Ruminant Production : Based On Experiences In Thailand, Maneewan Kamonpatana

The Thai Journal of Veterinary Medicine

The author has been much concentrating on biological regulation for enhancing fertility and growth with co-incidentally better health care. The three aspects of achievement of fertility, growth and health within one injection may be called “Three in One that is Mato-Matid technology”. However, Mato-Matid technology did provide a great deal of prime biological responses positively to several reproductive technologies in which some of them may be regarded as artificial breeding like IVM/IVF/IVC/ET/Cloning.

Efflux Of Osmolyte Amino Acids During Isovolumic Regulation In Hippocampal Slices, Rodrigo Franco, Octavio Quesada, Herminia Pasantes-Morales

School of Veterinary and Biomedical Sciences: Faculty Publications

The efflux of potassium (K⁺) and amino acids from hippocampal slices was measured after sudden exposure to 10% (270 mOsm), 25% (225 mOsm) or 50% (150 mOsm) hyposmotic solutions or after gradual decrease (22.5 mOsm/min) in external osmolarity. In slices suddenly exposed to 50% hyposmotic solutions, swelling was followed by partial (74%) cell volume recovery, suggesting regulatory volume decrease (RVD). With gradual hyposmotic changes, no increase in cell water content was observed even when the solution at the end of the experiment was 50% hyposmotic, showing the occurrence of isovolumic regulation (IVR). The gradual decrease in osmolarity elicited …

Equine Laminitis Reviewed, Jocelyn Nelson

Undergraduate Honors Capstone Projects

Laminitis, also known as founder, is one of the most devastating and crippling conditions affecting horses throughout the world today. Traditionally defined as the inflammation of the laminae within the hoof, laminitis actually presents itself as a complicated, multi-system disease, that, through a series of interrelated events, leads to a characteristic lameness. This lameness has serious economic and humane consequences because affected horses are often seen in pain, and frequently must be destroyed due to permanent damages within the hoof.

Zoonotics and Wildlife Disease: Publications

Background
The emergence of resistance to antimicrobial agents within the salmonellae is a worldwide problem that has been associated with the use of antibiotics in livestock. Resistance to ceftriaxone and the fluoroquinolones, which are used to treat invasive salmonella infections, is rare in the United States. We analyzed the molecular characteristics of a ceftriaxone-resistant strain of Salmonella enterica serotype typhimurium isolated from a 12-year-old boy with fever, abdominal pain, and diarrhea.
Methods
We used pulsed-field gel electrophoresis and analysis of plasmids and β-lactamases to compare the ceftriaxone-resistant S. enterica serotype typhimurium from the child with four isolates of this strain …

Genetic Resistance To Experimental Infection With In Red Deer (Cervus Elaphus), Colin G. Mackintosh, Tariq Qureshi, Ken Waldrup, Robert E. Labes, Ken G. Dodds, J. Frank T. Griffin

Michigan Bovine Tuberculosis Bibliography and Database

Tuberculosis (Tb) caused by Mycobacterium bovis is a worldwide threat to livestock and humans. One control strategy is to breed livestock that are more resistant to Mycobacterium bovis. In a 3-year heritability study 6 farmed red deer stags were selected from 39 on the basis of their differing responses to experimental challenge via the tonsillar sac with approximately 500 CFU of M. bovis. Two stags remained uninfected, two were moderately affected, and two developed serious spreading Tb. Seventy offspring, bred from these six stags by artificial insemination using stored semen, were similarly challenged with M. bovis …

The Thai Journal of Veterinary Medicine

Six-day embryos were recovered from 25 swamp buffalo cows treated with pregnant mare serum gonadotropin (2,500 iu PMSG, n=9) and follicle stimulating hormone (280 mg, n=12 and 400 mg FSH, n=4). Two techniques, non surgical collection from live animals and direct flushing after slaughter were compared. The oocytes were collected from ovaries immediately after slaughter by aspiration with or without ovarian chopping. The studies showed that 0.44+0.59 embryos were collected from PMSG group, while 1.38+1.31 embryos were collected in FSH group. Fifty percent to 60% of recovered embryos were transferable. The non surgical technique gave a low recovery rate (14.40%) …

The objective of the study was to investigate the possibility of collecting oocytes using transvaginal ultrasound-guidance, in swamp buffalo heifers, after gonadotropin stimulation. Five swamp buffalo heifers were given a single dose of 3,000 IU of Pregnant Mare Serum Gonadotropin (PMSG) intramuscularly in order to stimulate the ovaries. Examination of the ovarian responses were carried out 48h after stimulation, the follicles were subsequently punctured and the oocytes examine under a stereomicroscope. The results of the ovarian response were 6.6 ± 1.1 follicles per animal with an average diameter of 7.1 ± 4.1 mm. The mean number of oocytes collected per …

The Subdural Sinus Of The Freshwater Crocodile (Crocodylus Siamensis), Wimon Pothiwong, Pakorn Prachammuang, Weerapong Koykul

The Thai Journal of Veterinary Medicine

A blood sinus suitable for the collection of blood was studied in four freshwater crocodiles (Crocodylus siamensis). The sinus was located in the neck between the dura mater and the archnoid, which gave it its name "the subdural sinus". The procedure of blood collection in crocodiles is discussed in terms of possible injury to the spinal cord and the chance of getting cerebrospinal fluid mixed into the blood sample.

The Expression Of P53, C-Erbb-2 And C-Yes In Canine Skin Tumors, Anudep Rungsipipat, Susumu Tateyama, Yuichi Murakami, Kazuyuki Uchida

The Thai Journal of Veterinary Medicine

The exact role of the p53 tumor suppressor gene, c-erbB-2 and c-yes oncogenes in the development of canine skin tumors is still debatable. To elucidate the involvement of these oncogenes in canine skin carcinogenesis, we examined the expression of the protein in 60 skin tumor samples using avidin-biotin complex immunohistochemistry, with polyclonal antibodies directed against each protein, on formalinfixed, paraffin-embedded sections. Positive nuclear staining for p53 protein was observed in 12/60 cases (20%) which included, 6/15(40%) squamous cell carcinomas (SCC) and 4/8(50%) perianal gland tumors (PGT). Out of all the tumors examined, mixed membrane/ cytoplasmic staining of c-erbB-2 protein was …

The Thai Journal of Veterinary Medicine

Artificial Insemination (AI) in pigs has been well developed especially in the area of instrument design and semen preservation. AI techniques normally practiced as a routine, work well in Thailand swine breeding farms. Current research for the development of AI in pigs at the Department of Obstetrics Gynaecology and Reproduction, Faculty of Veterinary Science, Chulalongkorn University consists of: fractionated insemination, semen evaluation testing the ability of sperms to penetration oocytes and fertilise and the economic evaluation of AI boars raised in evaporative cooling systems. These researches have been reviewed in this report.

Virus-Induced Neuronal Apoptosis Blocked By The Herpes Simplex Virus Latency-Associated Transcript, Guey-Chuen Perng, Clinton J. Jones, Janice Ciacci-Zanella, Melissa Stone, Gail A. Henderson, Ada Yukht, Susan M. Slanina, Florence M. Hofman, Homayon Ghiasi, Anthony B. Nesburn, Steven L. Wechsler

School of Veterinary and Biomedical Sciences: Faculty Publications

Latent infections with periodic reactivation are a common outcome after acute infection with many viruses. The latency-associated transcript (LAT) gene is required for wild-type reactivation of herpes simplex virus (HSV). However, the underlying mechanisms remain unclear. In rabbit trigeminal ganglia, extensive apoptosis occurred with LAT^- virus but not with LAT⁺ viruses. In addition, a plasmid expressing LAT blocked apoptosis in cultured cells. Thus, LAT promotes neuronal survival after HSV-1 infection by reducing apoptosis.

Agonistic Behaviour And Biogenic Amines In Shore Crabs Carcinus Maenas, Lynne U. Sneddon, Alan C. Taylor, Felicity A. Huntingford, David G. Watson

Sentience Collection

To investigate the role of certain neurohormones in agonistic behaviour, fights were staged between pairs of size-matched male shore crabs Carcinus maenas, and blood samples were taken immediately after the contests had been resolved. Samples were also taken from these crabs at rest (before and after fighting) and after walking on a treadmill. A control group of crabs also had samples taken on each experimental day. Concentrations of tyramine, dopamine, octopamine, serotonin (5-HT) and norepinephrine were determined in each blood sample using a gas chromatography/mass spectrometry (GC-MS) system. Norepinephrine was not detectable in any of the samples, but the standards …

Bulletin 4394 - Exotic Diseases - Sheep And Goats, Agriculture Western Australia

Bulletins 4000 -

An exotic disease is a disease which does not occur in Australia.

If an exotic disease did occur in Australia it would cause production losses, stock deaths and stop exports of primary production. When export markets are lost they can only be re-established once it is proven the disease is eradicated. Some exotic diseases may be transmitted to humans

Prevalence Of Antibody To Hepatitis E Virus Among Rodents In The United States, Michael O. Favorov, Michael Y. Kosoy, Sergei A. Tsarev, James E. Childs, Harold S. Margolis

Zoonotics and Wildlife Disease: Publications

The recent identification of antibody to hepatitis E virus (HEV) in pigs, sheep, and cattle and characterization of an HEV isolated from domestic pigs suggest animal reservoirs for this virus. To investigate whether rodents might be a natural reservoir of HEV, the prevalence of anti-HEV was determined among a variety of species throughout the United States. Serum samples were obtained from 806 rodents of 26 species in 15 genera. Anti-HEV prevalence was assessed by 2 EIAs (mosaic protein- and 55-kDa protein-based), which gave concordant results. The highest prevalence of antibody was found in the genus Rattus (59.7%; 66/278). Overall, rodents …
