| description | The present study was undertaken to investigate the effects of the plane of
nutrition (PN) for growing-finishing pigs on growth performance and meat quality
in summer. One hundred and two barrows and 102 gilts weighing approximately 44
kg were placed on a high-, medium-, or low-plane grower diet (HPG, MPG, or LPG)
with ME and lysine concentrations ranging from 3.33 to 3.40 Mcal/kg and
0.93% to 1.15%, respectively, for 29 days in 6 replicates (pens)
in total. Pigs from each grower pen were divided into two finisher pens and
provided with a high-plane finisher diet (HPF) containing 3.40 Mcal ME and 9.5 g
lysine/kg and a low-plane finisher diet (LPF; 3.25 Mcal ME and 8 g lysine/kg),
respectively, up to approximately 110 kg, and slaughtered. Growth performance of
the pigs, including average daily gain (ADG), average daily feed intake (ADFI),
and gain:feed ratio, was not influenced by the grower-phase PN during any of the
grower phase, a 31-d finisher phase I, and ensuing phase II. However, both the
ADG and gain:feed ratio were greater (p < 0.05) for the
HPF group than for the LPF group during the finisher phase I (748 vs. 653 g with
SEM = 13 g and 0.333 vs. 0.299 with SEM = 0.008, respectively).
The ADG, but not gain:feed ratio, was greater for the HPF group vs. LPF during
the finisher phase II (673 vs. 623 g with SEM = 15 g for ADG and 0.322
vs. 0.323 with SEM = 0.005 for the gain:feed ratio). The carcass backfat
thickness (BFT) was greater for the LPF group vs. HPF within the pigs which had
been placed on LPG during the grower phase, but not within the pigs from the HPG
or MPG group. Physicochemical characteristics of the longissimus
dorsi muscle (LM) and sensory quality attributes of fresh and
cooked LM were not influenced by either the grower-phase or finisher-phase PN.
In conclusion, high PN is necessary for finishing pigs during the hot season to
minimize the reduced rate of weight gain and also to prevent the increase of BFT
that could result from low PN. |
