The Effects of Different Types of Feed Flavors on Feed Intake and Feeding Behaviors in Growing Pigs

The experiment was conducted to investigate the effect of different feed flavors on feed intake and intake behavior in growing pigs under auto feeding system. A total of 30 barrows (Landrace x Yorkshire) of 95 days old were selected and allocated to 1 of 5 treatments by BW for this 14 days experiment. There were 6 replicates in each treatment and 1 pig in each replicate. Diets containing: CON, the basal diet; BF, CON + 400 mg kg-1 banana flavor; MF, CON + 400 mg kg-1 sow milky flavor; SF, CON + 150 mg kg-1 sweetener and BMS, CON + 400 mg kg-1 banana flavor + 400 mg kg-1 milky flavor + 150 mg kg-1 sweetener. The ADFI in BF, MF, SF and BMS complex group was enhanced compared to the CON, respectively. The ADG and feed efficiency was respectively increased (p<0.05) related to the control treatment. The feed intake speeds and feed intake time of fruit, milky, sweetener and complex group were increased (p<0.05) than control. The results indicated that feed flavors affect feed intake behavior by elevating the feed intake speed and reducing the time of feed intake to enhance the feed intake of growing pigs and no difference was found between the three flavors.
