This document summarizes research on PCV2 vaccination protocols used in British pig production. Two field trials found that vaccinating sows with Circovac and piglets with either Circovac or Circoflex showed no significant differences in growth rates or mortality. Numerical advantages were seen in pigs vaccinated with Circovac in both trials. The document concludes that under field conditions, Circovac and Circoflex perform similarly as PCV2 vaccines for piglets.

1) A field survey of PCV2 antibody levels in gilts from 30 nucleus farms supplying 4 large French pig companies found wide variation in average titers, indicating different levels of exposure to PCV2 antigen during growth.
2) An example farm expanded from 450 to 800 sows. Vaccinating incoming gilts with CIRCOVAC upon arrival improved PCV2 antibody homogeneity and levels. Reproductive performance was good with high farrowing and weaning rates.
3) Maintaining high and homogeneous PCV2 antibody levels in replacement gilts through vaccination in quarantine is recommended to improve their ability to resist new PCV2 exposure when introduced to commercial farms.

This document discusses subclinical infections of porcine circovirus type 2 (PCVD). It notes that subclinical infections, which do not produce evident clinical signs, are much more common than clinical infections associated with the virus. The document explores ways to diagnose and measure the impact of subclinical PCVD infections, including through experimental infections, vaccination studies, and analyzing effects on mortality, average daily gain, and viral load in natural infections. While challenges exist, results consistently show that subclinical PCVD infections cause detrimental effects on pig production parameters that can be quantified through vaccination studies.

1) The study assessed the pathological consequences of PCV2 infection in conventional sows through artificial insemination with PCV2-infected semen.
2) Three of the six infected sows were not pregnant, while the other three were pregnant. All three sows in the uninfected control group were pregnant.
3) PCV2 was detected in at least one organ of the six infected sows. The sow with the lowest anti-PCV2 antibody levels showed the highest number of positive tissues and fetuses.
02 henry too
Henry Too presented on pig production in Asia and experiences with Circovac®. Pig farming ranges from small backyard operations to commercial farms. Circovac® is registered for use in several Asian countries and has been shown in trials to significantly reduce mortality and PCVD-specific mortality, improve growth rates, reduce time to slaughter, and decrease viral shedding compared to non-vaccinated pigs. The results demonstrate Circovac® is effective at controlling PCV2 infections across the whole herd through sow or piglet vaccination.

1) The study evaluated the impact of vaccination with Circovac on PCV2 shedding and tissue viral load in sows experimentally infected with PCV2.
2) The vaccinated group (VI) had lower virus shedding in samples collected and lower viral tissue loads compared to the unvaccinated (NVI) and control (C) groups.
3) Specifically, the VI group had fewer positive placentas and no positive fetuses, while the NVI and C groups did have some positive samples. This suggests vaccination reduced vertical transmission of the virus.

- The document discusses pig production in Spain and the author's experience vaccinating piglets against PCV2 (porcine circovirus type 2) using the Circovac vaccine.
- Problems with poor performance and increased mortality led the author to test for PCV2, finding it present. Vaccinating piglets resulted in reduced mortality, improved growth and feed efficiency, and economic benefits.
- However, the vaccine's effects can be limited if PRRS (porcine reproductive and respiratory syndrome) is also present, and both PCV2 and mycoplasma vaccines may be needed in some farms. Ongoing monitoring and adaptation is important.

1) This case report describes a 120-sow farm in Japan that implemented PCV2 vaccination of sows in 2008 and saw a reduction in post-weaning mortality without vaccinating piglets.
2) After sow vaccination, the farm's post-weaning mortality rate decreased substantially from around 20% to an average of 5.2% in 2012, though it fluctuated due to other disease issues.
3) Testing showed that PCV2 viral loads decreased after sow vaccination such that the virus was not detected in pigs of any age three years after vaccination began. Continued sow vaccination provided strong immunity and global protection across the farm.
Chapat et al.-orf1 et orf2 cmi with CIRCOVAC vaccination in sows
This study assessed the cell-mediated immune response against PCV2 ORF1 and ORF2 proteins in pigs vaccinated with an inactivated PCV2 vaccine. The results showed that vaccination induced gamma interferon production against both ORF1 and ORF2, primed pigs for interleukin-2 secretion after challenge, and stimulated antibody responses. In contrast, unvaccinated pigs only developed immune responses after challenge. The cellular immune response detected is expected to contribute to reduced PCV2 replication in vaccinated pigs. This highlights the importance of including both ORF1 and ORF2 in PCV2 vaccine design.

This study reviewed literature on the effects of vaccinating piglets against porcine circovirus type 2 (PCV2) with CIRCOVAC®. Mortality rates from weaning to slaughter were consistently lower in vaccinated piglets compared to unvaccinated piglets. A linear regression model found a strong correlation between the reduction in mortality after vaccination and the baseline mortality rate in unvaccinated pigs. The regression estimated a basic mortality rate of 4.57% and that vaccination can be expected to reduce mortality by 88% above this basic rate.
Apvs2013 10 lee et al.-trypanosomiasis in pigs in malaysia
This document summarizes an outbreak of trypanosomiasis in pigs in Malaysia. Nearly 40-50% of sows and boars on a 1,000 sow farm showed symptoms of pyrexia, anorexia, abortions and skin hemorrhages. Laboratory testing found trypanosomes in the pigs' blood and confirmed the presence of Trypanosoma evansi via PCR testing. Treatment with diminazine aceturate and isometamidium chloride resulted in clinical improvement and reduced mortality. The outbreak was likely caused by transmission of T. evansi from cattle and buffalo in nearby palm oil plantations by tabanid flies present on the pig farm.

Mortality rates from weaning to slaughter were consistently lower in vaccinated piglets compared to unvaccinated piglets. A linear regression model found a strong correlation between the reduction in mortality after vaccination and the baseline mortality rate in unvaccinated pigs. The regression estimated a basic mortality rate of 4.57% and that vaccination can be expected to reduce mortality by 88% above this basic rate.
Apvs2013 10 lee et al.-trypanosomiasis in pigs in malaysia
This document summarizes an outbreak of trypanosomiasis in pigs in Malaysia. Nearly 40-50% of sows and boars on a 1,000 sow farm showed symptoms of pyrexia, anorexia, abortions and skin hemorrhages. Laboratory testing found trypanosomes in the pigs' blood and confirmed the presence of Trypanosoma evansi via PCR testing. Treatment with diminazine aceturate and isometamidium chloride resulted in clinical improvement and reduced mortality. The outbreak was likely caused by transmission of T. evansi from cattle and buffalo in nearby palm oil plantations by tabanid flies present on the pig farm.
Apvs2013 08 tee et al.-csf test kit comparison
This study evaluated 4 commercial ELISA test kits for detecting antibodies to classical swine fever (CSF) by testing them on 6 standard serum samples. Test kit B detected antibodies in all samples, including those from pigs infected less than 21 days. Test kits S and I failed to detect antibodies in samples from pigs infected less than 21 days. The sensitivities of the test kits ranged from 60% to 100%. The performance of the test kits may depend on factors like the antigen used and the cut-off points designed for screening versus detection of true positives. More studies are needed to evaluate the test kits' ability to detect antibodies in pigs vaccinated for CSF.

This document summarizes a serological survey of Aujeszky's disease vaccination in an Italian pig herd. The herd vaccinated gilts, sows, growers, and fatteners using a vaccine called AKIPOR 6.3 mixed with another vaccine. Blood samples from gilts, sows, and fatteners showed high antibody levels against Aujeszky's disease, indicating the mixed vaccination program was effective at maintaining immunity. The survey results demonstrated that mixing AKIPOR 6.3 with an influenza vaccine did not negatively impact the potency of the Aujeszky's disease component of the vaccine.

This document summarizes a case report on the effects of introducing PRSSv vaccination with Progressis in addition to existing PCV2 vaccination with Circovac in an Italian pig farm. Key results included an improvement in the farrowing rate from 82.8% to over 90% after introducing Progressis vaccination for gilts and sows. Other positive impacts were a steady increase in litter size from 13.26 to 15.01 piglets born alive per litter between 2010-2012, and an increase in piglets weaned per sow from 24.87 to 27.42 over the same period despite lengthening the reproductive cycle. The case report concluded that PRSSv vaccination with Progressis was an effective tool to help improve
Apvs2013 06 castellan et al.-clinical case report of h1 n1pdm in italy
This document summarizes a clinical case report of an outbreak of pandemic H1N1 influenza virus (H1N1pdm) in an Italian pig farm between July 2012 and March 2013. The farm experienced increased respiratory disease and mortality in post-weaned pigs, testing confirmed the presence of H1N1pdm virus. A vaccination program was implemented using an inactivated trivalent swine influenza vaccine. Following vaccination of sows and piglets, clinical signs reduced and virus detection decreased, controlling the H1N1pdm outbreak.
Vila et al. Improvement of herd performance parameters after sow and piglet v...
This document summarizes the results of a case study conducted on a 2,700 sow farm in Bulgaria that implemented a full herd vaccination program against PCV2 using CIRCOVAC. The program involved vaccinating piglets at 28-30 days and sows. Results showed improvements in herd performance parameters, including increased litter size from 13 to 17.8 total born piglets, decreased days to 100kg by 5.3 days, improved daily weight gain, and stabilized health status by decreasing gastric ulcers and respiratory signs. The owner considers CIRCOVAC vaccination as a key tool for farm management and competitiveness.
Aasv2014 daresta et al. comparative pcv2 fetal protection-poster
This study evaluated the protective effects of two PCV2 vaccines (Vaccine A and Vaccine B) against fetal PCV2 infection in pigs. Gilts were vaccinated with one of the vaccines or unvaccinated as controls. After artificial insemination with PCV2-spiked semen, fetuses, placentas, and amniotic fluid were tested for PCV2. Vaccine A significantly reduced PCV2 positivity in fetuses compared to unvaccinated controls, but Vaccine B increased PCV2 positivity in placentas and amniotic fluid. The results suggest Vaccine A may better protect against subclinical fetal PCV2 infection than Vaccine B.
Aasv2014 callen et al. vaccination compliance to pcv2 using a dth test
This document describes two trials that tested a delayed type hypersensitivity (DTH) test to detect compliance with PCV2 vaccination. In the first trial, vaccinated pigs all showed a significant skin reaction to antigen injection, while 50% of unvaccinated pigs reacted. The reaction was strongest 20-24 hours after injection. Histology confirmed a type IV DTH response. The second trial found nearly all pigs vaccinated with CIRCOVAC reacted, while only 25% of those vaccinated with another PCV2 vaccine reacted. The DTH test shows potential as a practical way to check compliance with CIRCOVAC vaccination. Further studies are needed to improve specificity and standardize the technique in field conditions.
ESPHM2014 MERIAL Momentum
This document contains an abstract from a conference on Porcine Circovirus diseases. The abstract describes a field study comparing the effectiveness of three different PCV2 piglet vaccines (CIRCOVAC, Vaccine A, and Vaccine B) on a large Russian farm. Over 4,000 piglets were randomly assigned to receive one of the three vaccines and were monitored for average daily weight gain and mortality in the post-weaning and finisher stages. The results showed CIRCOVAC and Vaccine A performed similarly in terms of weight gain and mortality, while Vaccine B results were slightly lower. The study demonstrates the ability of CIRCOVAC to control PCV2 under field conditions in Russia comparable to another leading

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Promoting Wellbeing - Applied Social Psychology - Psychology SuperNotes
