Although a commensal, M. hyorhinis may cause serious systemic disease through mechanisms that are not fully understood.
One month after the beginning of the outbreak of reproductive failure in sows, acute respiratory disorder and diarrhoea that was non-responsive to antibiotics started in weaned pigs aged 6-8 weeks...
Control of outbreaks on problem farms in Asia remains an attempt to raise herd immunity by use of live virus feedback material. However, the current outbreaks have shown only transient herd immunity with these programs.
The efficacy of PCV2 vaccines to control PCV2 associated diseases has been clearly demonstrated not only in piglets but also in sows. Moreover, it is also feasible to vaccinate sows and their offspring without hampering its growth during the rearing period.
The total cost of productivity losses to US producers is estimated at US$664 million annually but productivity losses are shifting from the growing pig herd to the sow herd.
There was a sudden increase in mortality in a site 2 farm with the loss of the "biggest piglets" in the group.No particular symptomatology was seen but every day some dead piglets were found.
The prevalence of pleurisy is surprisingly high among pigs at slaughter. A recent review of available data ranged from 12.5% in the UK, 26% in Spain, to 41% of individual pigs slaughtered in one Norwegian study.
Experimental Mhyo and PCV2 co-inoculations have resulted in somewhat divergent results.
A sudden death of animals, with no prior symptoms of disease, and clinical symptoms such as massive facial, ears and forechest oedema, as well as an increase of body temperature to 41.5ºC, were observed.
A cough outbreak appeared in 8-9 weeks old piglets. It apparently was a "normal" outbreak that could be solved with a few days of antibiotic but the pigs did not respond to the treatment.
This study demonstrates the added profitability that air filtration can give to sow farms located in highly dense swine regions. However, it is important to point out that these figures are long term averages and not necessarily predictors for individual herds.
More than half of the pig population is housed in only one region with a very high pig density and it is very likely that elimination would only be possible with the help of a mandatory national program supported by the EU.
Genomic changes can be associated with increased virulence or decreased immunogenicity.
The desired result of the strategic management of replacement gilts at a company level is to minimize the economical losses potentially caused by PRRS.
The litter size of the recent and the last farrowing batches was significantly reduced, and the suckling pigs showed an obvious varying weight, condition and viability.
The PCV2 has been associated, in an ongoing way and throughout time, with more pathologies called, collectively, diseases associated with the PCV2 (PCVDs): PCV2 systemic disease, PCV2 lung disease, PCV2 enteric disease, PCV2 reproductive disease,PCV2 subclinical infection and porcine dermatitis and nephropaty syndrome.
