Table 5 Studies assessing the impact of the presence of pleurisy on average daily gain (ADG) in pigs.
From: Review on the methodology to assess respiratory tract lesions in pigs and their production impact
Reference | Study population | Impact on ADG | Comment |
|---|---|---|---|
[79] | 9592 pigs from 78 farms; examined in 4 slaughterhouses |  | Fattening period + 8 days |
[51] | 4 studies | −34% | Feed conversion ratio + 26% |
[29] | 4800 pigs, selected on specific days in one slaughterhouse | Lower carcass weight | Effect was shown in multivariable logistic model with carcass weight being negatively associated with pleurisy lesions |
[36] | 2 farms (578 pigs) | Farm A: no effect Farm B: -28 g /−42 g | Effects in farm B were depending on localization of pleurisy: dorsocaudal pleurisy: no effect; parietal pleurisy: −28 g; antero-ventral pleurisy: −42 g |
[54] | 14 farms (6997 pigs) | −39 g (−5.2%) | Large differences between farms (range: -19.9% to +4.6%) Severity of pleurisy: score 1: −54 g; score 2: −37 g Fattening duration +6 days Pleurisy and CVPC: ADG −15% (synergistic effect) |
[69] | 39 farms (one batch per farm) | No effect | No effect on feed conversion ratio Performance data were analysed at farm level; lung lesions were assessed on one subgroup (35 pigs) at slaughter |
[8] | 1 farm (108 pigs) | −11% |  |
