We investigated the effect of cellooligosaccharide (CE) or a combination of dextran and Lactobacillus casei ssp. casei strain JCM1134 T (synbiotic; SB) feeding on growth performance, fecal condition and hormone concentrations in Holstein calves. Fifty-two female Holstein calves were randomly assigned to three treatment groups: CE feeding group (n=16), SB feeding group (n=18), and control group (n=18). Body weight at 90days of age, as well as daily body weight gain (DG) and feed efficiency after weaning to 90days of age were greater (P<0.05) in the CE feeding group than in the control group. The total fecal score tended to be lower (P<0.1) in the SB feeding group than in the control group. Plasma insulin concentration was higher (P<0.05) in the CE feeding group than in the control group at 90days of age. Our results indicate that CE feeding improved DG and feed efficiency in calves. On the other hand, there was less effect on growth performance and fecal Escherichia coli counts in calves fed SB.
