A total ofeight 11-wk trials were conducted to evaluate the productivity and aggression at
\ngrouping ofgrower-f inisher pigs [initial body weight (BW)= 31.8 \u00b1 5.4 kg (mean \u00b1 SD), n=2304] in two group size
\ntreatments (18 and 108 pigs pen-1). Pigs were housed on fully-slatted floors, provided one wet\/dry feeder space for every
\nnine pigs, and a floor space allowance of 0.76 m2 pig-1 in both group sizes. The level ofaggression at grouping was
\nrecorded for 2 h starting 0, 24 and 48 h following grouping into small and large groups. Pigs were weighed on weeks 0, 2, 5,
\n7 and 11, and average daily gain (ADG) was obtained. Average daily feed intake (ADFI) was recorded during two periods
\n(weeks 2 to 5 and 7 to 11). There was no difference in percentage of time spent on aggression between two group sizes up to
\n48 h following grouping. ADG for the entire 11-wk trial was affected (2 %) by large group size (0.971 and 0.955 kg d-1 for
\ngroups of 18 and 108, respectively; P<0.05). However, the greatest effect on ADG was observed during the first 2 wk\nfollowing grouping (0.919 and 0.833 kg d-1 for groups of 18 and 108, respectively; P<0.001). There were no significant\neffects due to group size on ADFI, feed efficiency, variability in final BW within a pen, carcass traits or mortality and\nmorbidity (P>0.05). In summary, the overall productivity and aggression at grouping did not differ substantially between
\ngroup sizes of 18 and 108 pigs pen-1.<\/p>\n","protected":false},"excerpt":{"rendered":"
