Pleurisy risk higher with large number of pigs
The larger the number of animals within a confined
space, the greater the risk of pleurisy.
That, in short, was concluded by the Dutch Animal Sciences Group at
Wageningen University and Research Centre in conjunction with the Veterinary
Centre Someren and Intervet in a study about pleurisy, the Dutch agricultural
newspaper Agrarisch Dagblad reports.
The study questioned
whether it was possible to reduce the number of pigs with pleurisy on the
At the swine research and information centre in
Sterksel, the Netherlands, it was investigated whether by delivering pigs in one
group from birth to the slaughterhouse, without mixing them with the other pigs,
the incidences of pleurisy could be lowered.
results of this group of pigs were compared with a group which was sorted
according to weight from the weaning stage. In the farrowing house, the
non-mixed group of piglets grew quicker and were heavier at the weaning stage
than the mixed group.
However, there were no differences between
both groups at weaning stage regarding feed intake and feed
In total, the non-mixed group grew 16 g
per day quicker and had 1.1 mm thicker muscles than their mixed counterparts.
The percentage of finished pigs with infected lungs had decreased from 10.3 to
5.9% by not mixing the animals.
The delivery weight to the
slaughterhouse was also not affected by mixing/not mixing.
