An adaptation of the nonhuman animal observation section of the 2003 Swine
\nWelfare Assurance program (SWAP) was utilized to evaluate the behavior of
\nweaned pigs following vaccination with Ingelvac MycoFLEX\u00ae (Boehringer
\nIngelheim Vetmedica, Inc., St. Joseph, MO) and Respisure\u00ae-One (Pfizer Animal
\nHealth, Exton, PA). The objective was to determine if field observations of
\nmarkedly reduced pig activity following vaccination with certain Mycoplasma
\nhyopneumoniae vaccines could be confirmed and quantified by observing postvaccinal
\npig behavior and feed disappearance. A total of 1,832 weaned pigs
\n17\u201323 days of age were allocated across 72 nursery pens (36 pens per treatment
\ngroup), resulting in approximately 25 pigs\/pen with pen as the experimental
\nunit.
\nPigs were evaluated to determine willingness to approach and feed disappearance
\nbehavior pre- and postvaccination with each population of pigs serving as
\nits own prevaccination baseline for postvaccination behavior observations. After
\nentering and crouching down in a pen, the blinded observer counted all pigs who
\napproached him during a 15-s period. The pigs approaching the observer were
\ndesignated as willing to approach. The difference in pre- and postvaccination
\nvalues is reported here as a decrease in percentage approachability.
\nA significant decrease in postvaccination willingness to approach was observed
\nwithin both groups of pigs (p < .0001). However, the decrease in
\nwillingness to approach was significantly less for the Ingelvac MycoFLEX\u00ae
\nvaccinated pigs compared with the Respisure-One vaccinated pigs (11.38% vs.
\n27.05%, p < .0001). The Ingelvac MycoFLEX\u00ae vaccinated pigs consumed
\nsignificantly more feed through 24 and 48 hr postvaccination (p < .0001 and
\np D .0001, respectively). These findings suggest that willingness to approach and feed consumption may be useful parameters for assessing vaccine reactivity
\n(side effects) in pigs.<\/p>\n","protected":false},"excerpt":{"rendered":"
