This study was conducted to examine the effect of brown rice grain as an alternative ingredient to corn on the weaning-to-estrus interval, and immunoglobulins in the milk and serum of lactating sows, and the growth performance of piglets. A total of 13 lactating sows were randomly assigned to receive corn-basal diet (Control) or brown rice grain-based diet (RG) from next day to 21 days after farrowing at 2nd parturition. Feed intake, body weight loss, back fat loss, and weaning-to-estrus interval of sows and growth performance of piglets were not affected by experimental diet. There was no significant change in IgA and IgG levels in milk ; however, total protein level in plasma and IgG in serum of RG pigs are higher than those of Control pigs (P < 0.05). These results indicated that dietary brown rice grain as an alternative ingredient to corn for lactating sow do not affect the growth performance and weaning-to-estrus interval but increase IgG of swine serum.
