description This study was conducted to investigate the effects of different amounts of konjac flour (KF) inclusion in the gestation diet on the physio-chemical properties of diets, postprandial satiety in pregnant sows, lactation feed intake of sows and piglet performance during two successive reproductive cycles. Multiparous Landrace sows (n=140) were assigned randomly to one of four experimental diets, and four gestation diets were formulated to contain varying amounts of KF at 0%, 0.6%, 1.2% or 2.2%, respectively.

The water binding capacity (WBC) (P<0.01), swelling capacity (P<0.01) of gestation diets, the concentration of total short chain fatty acids (P<0.05) after in vitro fermentation of gestation diets increased linearly with increasing inclusion amounts of KF.

In addition, there was a linear decrease of the non-feeding oral behavior of gestating sows (P<0.01) when dietary KF increased.
