RESULTS
Performance of lactating sows is shown in Table 4. At
birth, due to the practice of cross-fostering, litter size
did not differ among treatments and averaged at
10.37 ± 0.74. Likewise, no difference was observed in
individual weight and litter weight among treatments
at parturition. Weaning weight of nursing piglets
was numerically increased by 5.83% (5.99 ± 0.59 vs.
5.66 ± 1.09 kg) in the FMA group as compared to the
CON group. Furthermore, litter weight gain tended to
be heavier in the FMA group than those in the FM
group (P = 0.05). During lactation, sow ADFI tended
to increase (+5.5%, P = 0.093) in the FMA group in contrast to the CON group. Compared with sows fed
FM flavor and sodium butyrate, ADFI was significantly increased by 13.2% (4.93 ± 0.34 vs. 5.58 ± 0.30 kg/
day) and 10.7% (5.04 ± 0.54 vs. 5.58 ± 0.30 kg/day)
in sows fed FMA flavor during lactation (P < 0.05),
respectively. FMA flavor also improved ADFI of
sucking pigs among treatments (P < 0.05).
