Willingness-to-approach behavior of weaned pigs after injection with Mycoplasma hyopneumoniae vaccines

چکیده
Materials and methods: Three studies were conducted. Two weeks post nursery placement, pigs 17 to 23 days old were evaluated to determine WTA using the Swine Welfare Assurance Program behavioral protocol. Pigs were observed at 4:00 pm the day before injection and at 4:00 pm 24 hours later, 6 hours post injection. The difference between the two WTA scores is reported as a decrease in percent willing to approach. In Study One, 1832 pigs were vaccinated either with MycoFLEX (36 pens) or RespiSure-ONE (36 pens). In Study Two, 2568 pigs were injected with MycoFLEX (39 pens), RespiSure-ONE (39 pens), or saline (38 pens). In Study Three, 1750 pigs were injected with saline (35 pens) or not injected (35 pens).

Intradermal vaccination for Mycoplasma hyopneumoniae
Results: Injection site reactions were minimal for all vaccines. Pigs vaccinated ID, either by needle or needleless injector, had significantly higher M hyopneumoniae antibody titers than did pigs vaccinated by IM injection. Pigs vaccinated by needleless ID injection had lower lung lesion scores and higher IgA and IgG titers in bronchoalveolar lavage fluid than did nonvaccinates following chall...

A low-cost modified medicated-early-weaning program to eliminate Mycoplasma hyopneumoniae was tested in growing pigs from two swine operations over a 12-month period. Pigs received a series of injections of oxytetracycline on days I, 7, and 14 of age. Pigs were weaned at 14 days of age to off-site nurseries. A thorough diagnostic examination targeted towards detecting M. hyopneumoniae was emplo...

Materials and methods: Weaned pigs (n = 296) were each vaccinated with one of three M hyo bacterins or a placebo and challenged 3 and 5 weeks after the second vaccination with M hyo and PCV2, respectively. A subset of pigs, necropsied 2 or 4 weeks after PCV2 challenge, were evaluated for clinical signs, lesions, PCV2 serum levels, and M hyo in bronchial alveolar lavage fluids. Antibody titers t...

BACKGROUND A field trial was carried out with two Mycoplasma hyopneumoniae vaccines in order to investigate the benefit of vaccination under field conditions in modern Danish pig production facilities with pigs being positive for M. hyopneumoniae. The M. hyopneumoniae infection of the herd was confirmed through blood samples that were positive for antibodies against M. hyopneumoniae combined wi...

The objective of this study was to determine the effects of porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae vaccinations on disease severity in an experimental PCV2-M. hyopneumoniae dual challenge model. Vaccine effectiveness was evaluated using microbiological (PCV2 viremia and M. hyopneumoniae nasal shedding), immunological (neutralizing antibodies and interferon-γ-secreting cel...
