A Mark–Recapture Technique For Monitoring Feral Swine Populations, Matthew M. Reidy, Tyler A. Campbell, David G. Hewitt
USDA Wildlife Services: Staff Publications
Techniques to monitor populations of feral swine (Sus scrofa) relative to damage control activities are needed on rangelands. Our objectives were to describe and assess a mark–recapture technique using tetracycline hydrochloride (TH) for monitoring feral swine populations. We established bait stations at study sites in southern and central Texas. During 1 d, we replaced normal soured corn bait with bait containing TH and counted the number of feral swine that consumed bait with observers. We conducted feral swine removal using box-style traps and helicopters, at which time we collected teeth for TH analysis. In southern Texas, we estimated …

The Thai Journal of Veterinary Medicine
Forced impregnation process is normally performed under vacuum at freezing temperature which requires expensive plastination apparatus. To reduce the cost in the plastination process, forced impregnation of porcine hearts under two different environments, which are at the freezing temperature (-20oC) and at room temperature (22-25oC), was compared. Twelve porcine hearts were collected from a slaughter house, and divided into the groups, six in each, and subjected to be plastinated by S10 standard technique at the two temperatures. Although the forced impregnation at room temperature, also the curing process, was more time-consuming, all hearts from both groups produced satisfying plastinated specimens. …

Prevention And Control Of Respiratory Diseases Excluding Mycoplasma Hyopneumoniae, Stanley Done, David Burch
Prevention And Control Of Respiratory Diseases Excluding Mycoplasma Hyopneumoniae, Stanley Done, David Burch
The Thai Journal of Veterinary Medicine
Significant changes in respiratory disease have occurred over the last 20 years. There are two primary reasons for this. In the first instance, there has been the occurrence of two major worldwide plagues-PRRS and PCV2-associated diseases. The second reason has been the considerable advances in vaccination, which have become available for some of the respiratory diseases, in particular Mycoplasma hyopneumoniae. Vaccines have also become available for porcine reproductive and respiratory syndrome virus (PRRS), influenza viruses (outside UK) and probably in the near future against porcine circovirus type 2 (PCV2).
Strategies For The Control Of Respiratory Disease, Stanley Done
Strategies For The Control Of Respiratory Disease, Stanley Done
The Thai Journal of Veterinary Medicine
This is a paper about common sense and respiratory disease using information that has been known for some time i.e. historical, and which is not accessed when a literary search is supplied by a computer. Respiratory disease in pigs has its most serious effects in the finishing stages, when the sequelae to progressive atrophic rhinitis, enzootic pneumonia and Actinobacillosis are most severe. Nowadays this relatively simple position is even more complicated by the worldwide occurrence of porcine reproductive and respiratory syndrome (PRRS) and porcine circovirus type 2 (PCV-2)-associated diseases principally PMWS where no vaccination is practised. Up to 80% of …

Anti-Capsular Antibodies Activate Killing Of Escherichia Coli O8:K87 By The Alternate Complement Pathway In Porcine Serum, N. M. Clark, E. M. Berberov, M. Wang, Rodney A. Moxley
School of Veterinary and Biomedical Sciences: Faculty Publications
Enterotoxigenic Escherichia coli (ETEC) strains that produce K88 (F4) + fimbria are important causes of diarrhea and post-diarrheal septicemia in swine. ETEC O8:K87, a serotype represented by a number of these strains, is typically serum resistant. Strain-specific antibodies are known to activate alternative C pathway-mediated killing of other serum-resistant E. coli [Hill, A.W., Shears, A.L., Hibbitt, K.G., 1978. The requirement of specific antibody for the killing of E. coli by the alternate complement pathway in bovine serum. Immunology 34, 131–136], but their antigenic targets have not been determined. We tested the hypothesis that anti-K87 antibodies activate alternative pathway-mediated killing of …
Relationships Between The Immune System And Stress Reactivity In Pig: Visualizing The Immuno-Neuroendocrine Framework In Action, Sanipa Suradhat
Relationships Between The Immune System And Stress Reactivity In Pig: Visualizing The Immuno-Neuroendocrine Framework In Action, Sanipa Suradhat
The Thai Journal of Veterinary Medicine
Activation of the immune system is regulated through several mechanisms, within the system itself and by other body systems, in order to maintain disease resistance, and prevent immune-mediated disorders within the host. It is well accepted that the immunological, physiological, behavioral, and psychological state of an animal are closely linked and the factors affecting one feature of the network can influence the rest of the system.In recent years, our understanding of the interactions between the neuroendocrine network (i.e. the hypothalamicp tuitary- adrenal axis, HPA) and immune-mediated inflammatory reactions has expanded enormously. This article outlines the nature of the immuno-neuroendocrine network …

Intrauterine Artificial Insemination In The Pig: The Techniques, The Applications And The Limitations, Tuempong Wongtawan, Peerapong Samransarp, Padet Tummaruk
The Thai Journal of Veterinary Medicine
This review aims to update information on the success of intra-uterine and deep intra-uterine insemination in the pig. Three artificial insemination (AI) techniques in pigs included conventional AI (semen is deposited intra cervically), intra-uterine insemination (IUI) and deep intra-uterine insemination (DIUI). With conventional AI, it has been shown that more than 90% of spermatozoa are lose before reaching the oviducts. Therefore, new techniques for AI were developed in order to maximize the use of boar semen and to reduce semen backflow, which can reduce pregnancy rates. The advantages of intra-uterine and deep intra-uterine insemination include a reduction in the number …
Hyaluronan In The Sow’S Oviduct: Its Effect On Boar Sperm Morphology And Function, Paisan Tienthai
Hyaluronan In The Sow’S Oviduct: Its Effect On Boar Sperm Morphology And Function, Paisan Tienthai
The Thai Journal of Veterinary Medicine
During sperm transport in the female pig, a proportion of the spermatozoa is arrested at the uterotubal junction and the isthmus, where an oviductal sperm reservoir is built up. The sperm reservoir maintains sperm viability and controls the release of fertilizing spermatozoa so that only a small subpopulation reaches the site of fertilization, thus diminishing the risk of polyspermy. In vitro research has focused on sperm binding as the main mechanism of sperm storage, sperm release and modulation of capacitation, but little attention has been paid to the sperm reservoir fluid, its composition and the control of capacitation in vivo. …

Fas Ligand Expression In The Porcine Oviduct, Paisan Tienthai, Yumi Hoshino
The Thai Journal of Veterinary Medicine
The expression of Fas/Fas Ligand (FasL) is thought to be involved in the immune privileged status of the testis, cornea and the placenta. The objective of this study was to see whether FasL mRNA was expressed in the epithelium of the porcine oviduct, where spermatozoa, oocytes and developing embryos avoid elimination by the female immune system during the estrous cycle. The distribution of Fas/FasL might provide information about immune privileged sites in the pig oviduct. The gene expression of FasL was detected in the uterotubal junction (UTJ), isthmus and ampulla of the pig oviductal epithelium, during both pre- and post-ovulatory …

All oocytes were divided into four groups; immature (control group), the in vitro maturation group (control group), frozen immature and frozen mature oocytes. Electron microscopy was …
The Function Of The Oviduct In Relation To Sperm Transport And Capacitation In Swine, Paisan Tienthai
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 …

Seasonal Effects On The Reproductive Performance Of Gilts And Sows, Padet Tummaruk, Wichai Tantasuparuk, Mongkol Techakumphu, Annop Kunavongkrit
The Thai Journal of Veterinary Medicine
Although the domestic pig is not a true seasonal breeder, a seasonal effect on reproductive performance exists. A reduction in reproductive performance during some periods of the year is most pronounced in primiparous sows and is manifested in various ways such as, delayed puberty, prolonged weaning-to-first-service interval (WSI), increased number of sows returning to oestrus after mating, decreased conception rate, decreased farrowing rate (FR), decreased litter size and an increased incidence of abortion. Both high ambient temperatures and/or changes in photoperiod have been reported to be the cause of these problems. The pig is considered to be a short-day seasonal …
