摘要：
Changes in plasma cholecystokinin (CCK) levels after feeding were investigated in dairy cows. Three Holstein-Friesian lactating cows given concentrates at 06.00 and 13.00 h and hay at 16.30 h were used. Blood samples were taken from the jugular vein from 0 (before feeding, 13.00 h) to 6 h at 1-h intervals. The immunoreactivity of CCK was expressed in terms of the CCK-8 equivalent. The plasma concentration of CCK was not changed over the experimental period. This result might be reflected by the continuous flow of digesta from the rumen.
