Summary: | This study was performed to development the alternative farrowing pen (AFP) and
to investigate performance and behavior of lactating sows and their litter. A
total of 64 multiparous sows were randomly divided into two groups and were
allocated to farrowing crates (FCs) and AFPs. The AFPs contained a crate and
support bars that could be folded to provide the sows with extra space on day 5
postpartum. Behavior was recorded by charge-coupled device cameras and digital
video recorders, and the data were scanned every 2 min to obtain an
instantaneous behavioral sample. Farrowing systems did not affect feed intake,
back-fat thickness, litter size and piglet weight at birth and weaning
(p > 0.05). In addition, there were no differences in
the number of crushed piglets between the two farrowing systems
(p > 0.05). However, the weaning-to-estrus interval was
shorter in the sows of the AFPs than in thous of the FCs (p
< 0.05). The sows spent most of their time lying down during the lactating
period, at about 80% lateral recumbency and 10%–15% ventral recumbency.
The only significant differences were in the feeding and drinking behavior
between sows in the two farrowing systems (p < 0.05). The FC
sows displayed more feeding and drinking behavior than the AFP sows, especially
in the late lactating period (p < 0.05). Piglets in the FCs
tended to spend more time walking than piglets in the AFPs (p
< 0.05), whereas there were no differences in suckling and lying behavior
between piglets in the two farrowing systems (p > 0.05). It
is concluded that the AFPs with temporary crating until day 4 postpartum did not
negatively affect performance and crushed piglet compared with the FCs. It also
may improve animal welfare by allowing sows to move and turn around during the
lactating period. Further research is needed to find suitable housing designs to
enhance productivity and animal welfare. |
