| Popis: | Two field studies were conducted to determine the efficacy of difructose anhydride III (DFA III) as a supplement in colostrum replacer (CR) for improving the general health status (judged on the basis of incidence of enteritis, bronchitis, and pneumonia) of group-housed suckling Japanese Black calves. In a preliminary study, CR supplemented with DFA III (6 g) was orally administered within 24 h of calving to eight individually reared calves fed colostrum (DFA III group) (Exp. 1). Subsequently, CR supplemented with DFA III (6 g) was orally administered twice within 2 and 12 h of calving to four calves (DFA III group) that were not fed colostrum (Exp. 2). In both experiments, the health status of the calves was assessed during the preweaning period. In Exp. 2, hematological and blood-chemistry parameters were analyzed 24 h after the second administration of CR and at 1 wk and 1 month after calving. The results were compared between the DFA III and control groups (without DFA III supplementation; Exp. 1: n = 10, Exp. 2: n = 4). In Exp. 1, the number of calves requiring medications for the treatment of enteritis, bronchitis, and pneumonia during the pre- weaning period was significantly (p |
