摘要: It is often argued that pigs raised under less intensive production conditions – such as organic or free-range have a higher level of animal welfare compared with conventionally pigs. To look into this, an analysis data from large Danish abattoir slaughtering organic, free-range, and finishing was undertaken. First, the requirements for each three types systems were investigated. Next, meat inspection period 1 year collected. These covered 201,160 organic/free-range 1,173,213 The prevalence individual type lesion calculated, followed by statistical comparison between prevalences in conventional Because number data, P-value significance lowered to P = 0.001, only biological associations reflecting Odds Ratios above 1.2 below 0.8 considered be significance.
