Uittreksel
Authorities of many countries, including Belgium, impose control measures such as culling
of contaminated fl ocks, indoor confi nement of captive birds or fencing off outdoor ranges
with nets to prevent the spread of avian infl uenza (AI) during high-risk periods. The level of
protection provided by these measures, however, may be affected by poor compliance due to
actual or perceived concerns about their effectiveness, feasibility and consequences on animal
welfare. These concerns have led to calls for alternative AI-control measures, e.g. vaccination,
reduction of bird stocking density or banning free range systems in high-risk regions. In this
study, Flemish professional egg producers (FAR, n=33, 18% of all producers) and private
keepers of several species of captive birds (PRI, n=263) were surveyed with an online survey
tool (LimeSurvey, www.LimeSurvey.org) on their opinion about current alternatives measures
against AI. The participants were recruited via e-mail and by phone (FAR), via social media,
and via specifi c organizations of poultry and other birds (PRI). The responses were presented
as percentages and were statistical analyzed using a logistic regression model. In general,
FAR reported better compliance (69% vs 49%) and greater belief in the effectiveness of
indoor confi nement (87% vs 25%) compared with PRI. Although compliance was high (69%),
FAR were less positive about the effectiveness (10% vs 73%, P<0.05) and feasibility (10%
vs 44%, P<0.05) of covering the outdoor range with nets than PRI. The most adverse animal
welfare consequences of confi nement reported by FAR were increased feather pecking (52%),
cannibalism (48%), stress and frustration (42%), and poorer condition of the feathers, wattle
and body (35%). The same was seen for PRI (stress & frustration, 60%; poorer condition of
the feathers, wattle and body, 55%). Of the various alternative control measures against AI,
vaccination and banning free-range systems were most preferred among FAR (58% and 45%).
Also vaccination was most preferred (62%) by PRI, whereas banning free-range systems
and reducing bird density in high- risk regions were less preferred (3% and 14%). Limited
compliance by PRI may compromise the effectiveness of current AI control measures in
Belgium. Considerable impairments of bird welfare due to indoor confi nement are reported by
FAR and by PRI in particular. Given the huge numbers of birds that are culled each year under
the current AI control policy, these fi ndings amplify the call for alternative or complementary
control measures such as vaccination.
