Requirements to control the large decrease in serum @entity460 (Ca) due to parturition and to increase the feed intake soon after parturition have been well accepted in dairy @entity291 . This study was aimed to investigate the feed intake affected by serum Ca concentration with difructose anhydride ( @entity12606 ) III supplement in dairy @entity291 soon after parturition. Fourteen transition Holstein @entity291 were divided into @entity12606 and control (CONT) groups within 1 to 5 parity variations in each group. Measurement schedule for an individual @entity291 was from 14 d before parturition to 7 d following parturition. The @entity291 in @entity12606 group were supplied 0.2 kg/head/d of @entity12606 III feed containing 40 g of pure @entity12606 III while the @entity291 in CONT group received no @entity12606 III. Other feeding procedures were the same for all @entity291 in both groups. At parturition (d 0), serum Ca concentration sharply declined in both groups (p<0.05). Time interval for recovery from decreased serum Ca to its normal range (>9.0 mg/dL) tended to be faster in @entity12606 group (12 h) than in the CONT group (48 h), but the differences were not significant. Active ruminal contraction was observed in @entity12606 group at following parturition of d 1 (p<0.05), d 3 (p<0.05), and d 5 (p<0.01). @entity62 ( @entity62 ) intake did not differ between the groups. However, positive correlations were observed between serum Ca concentration and ruminal contraction (p<0.001), and between ruminal contraction and @entity62 intake (p<0.001) during following parturition. According to multiple regression analysis (R(2) = 0.824, p<0.001), the @entity62 intake was positively affected by serum Ca concentration and ruminal contraction. These results suggest that feed intake soon after parturition in dairy @entity291 can be increased by improvement of serum Ca concentration and active ruminal contraction, but @entity12606 III supplementation in this study did not improve the lower serum Ca concentration due to parturition.
