Bottom Line: 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 DFA group (12 h) than in the CONT group (48 h), but the differences were not significant.Dry matter (DM) intake did not differ between the groups.

ABSTRACT
Requirements to control the large decrease in serum calcium (Ca) due to parturition and to increase the feed intake soon after parturition have been well accepted in dairy cows. This study was aimed to investigate the feed intake affected by serum Ca concentration with difructose anhydride (DFA) III supplement in dairy cows soon after parturition. Fourteen transition Holstein cows were divided into DFA and control (CONT) groups within 1 to 5 parity variations in each group. Measurement schedule for an individual cow was from 14 d before parturition to 7 d following parturition. The cows in DFA group were supplied 0.2 kg/head/d of DFA III feed containing 40 g of pure DFA III while the cows in CONT group received no DFA III. Other feeding procedures were the same for all cows 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 DFA group (12 h) than in the CONT group (48 h), but the differences were not significant. Active ruminal contraction was observed in DFA group at following parturition of d 1 (p<0.05), d 3 (p<0.05), and d 5 (p<0.01). Dry matter (DM) 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 DM intake (p<0.001) during following parturition. According to multiple regression analysis (R(2) = 0.824, p<0.001), the DM intake was positively affected by serum Ca concentration and ruminal contraction. These results suggest that feed intake soon after parturition in dairy cows can be increased by improvement of serum Ca concentration and active ruminal contraction, but DFA III supplementation in this study did not improve the lower serum Ca concentration due to parturition.

Mentions: Ruminal contraction was auscultated from upper left flank of the cow using stethoscope connected sound recorder (ICR-S340RM, Sanyo Electric Co., Ltd, Osaka, Japan). Recording was performed for 5 min in each auscultation at d 14, and 7 before parturition and at d 0, 0.25, 0.5, 1, 2, 3, 4, 5, and 7 following parturition. Recording before parturition (d 14 and 7) and after parturition (d 4, 5, and 7) were almost completed at 05:30 h before morning feeding (soon after blood sampling), but sampling for d 0, 0.25, 0.5, 1, 2, and 3 following parturition was performed counting from parturition hour. The number of ruminal contraction (time/min) was determined by dividing the number of contract frequencies within 5 min recording by 5 from both of direct auscultation and checking the sound waves processed by Sound it! 5.0 for windows (SIT50W, Internet Co., Ltd, Osaka, Japan) (Figure 1).
