Influence of Jerusalem artichoke tuber as a prebiotic on the nutrient utilization, weaning stress indicators and immunocompetence of crossbred calves during the pre- and post-weaning phases
This study explored the potential prebiotic properties of pulverized Jerusalem artichoke tuber (JAP) in pre- and post-weaned calves. Accordingly, 24 fifteen-day-old calves were randomly assigned to four groups (n = 6). The groups received JAP supplementation at levels of 0 (CON), 1 (JAP1), 2 (JAP2),...

Zusammenfassung: | This study explored the potential prebiotic properties of pulverized Jerusalem artichoke tuber (JAP) in pre- and post-weaned calves. Accordingly, 24 fifteen-day-old calves were randomly assigned to four groups (n = 6). The groups received JAP supplementation at levels of 0 (CON), 1 (JAP1), 2 (JAP2), and 3 (JAP3) percent of dry matter intake (DMI) during the first 60 days of the 120-day experiment. Two 6-days digestion trials were conducted: one during the 4th week of the experiment (pre-wean), and the second during the tenth week (post-wean). Additionally, serum concentrations of cortisol and epinephrine were measured in both the pre- and post-weaning phases to assess the stress levels. Immunocompetence of the calves during both the stages was evaluated through lymphocyte proliferation response. In the pre-weaning phase, the calves supplemented with JAP had better (P |
