ABSTRACT
We examined the effects of sodium butyrate and flavors on feed intake of lactating sows and growth performance of
piglets. A total of 52 primiparous sows (Large White) were randomly divided into four treatments (n = 13) and received
6 g/kg sodium butyrate (SB), fruit-milk (FM) flavor and fruit-milk-anise (FMA) flavor with pair feeding to the mothers
receiving the control diet. The feeding trial lasted for 29 days, including 21 days of nursing and 8 days of post-weaning
period, respectively. The nursing and weaning piglets received creep diets with the same flavor or SB supplement as their
mother. The results showed that FMA flavor increased average daily feed intake (ADFI) of lactating sows (P < 0.01), as well
as improved litter weight gain (P = 0.05) and ADFI (P < 0.01) of nursing pigs among treatments. Indeed, greater ADFI and
average daily gain of weaning piglets for the initial 8 days after weaning was observed in the FMA group compared with
those in the control group (P < 0.01). These findings indicated that adding FMA flavor was superior to SB for increasing
feed intake of lactating sows and improving growth performance of piglets.
