Enhanced Bactericidal Activity against Escherichia coli in Calves Fed Morinda citrifolia (Noni) Puree

Abstract: Background: Although adequate colostrum intake and properly used antibiotics can provide much protection for the bovine neonate, increased antibiotic scrutiny and consumer demand for organic products have prompted investigations of natural immunomodulators for enhancing calf health. One plant-based immunomodulator, Morinda citrifolia (noni) fruit, is a wellrecognized natural product that has a broad range of immunomodulatory effects.Hypothesis: Neonatal calves fed noni puree would demonstrate whole blood phago… Show more

“…In earlier findings, Brooks et al (2009) reported that supplementation of juice from M. citrifolia enhanced the activation of CD4+ and CD8+ T cells in neonatal calves. Bactericidal effect of noni was evaluated via an ex vivo whole blood bactericidal assay by Schäfer et al (2008). Result showed that noni fed group showed significantly more killing power at day 14 when compared to control calves.…”

“…Calf health was evaluated through daily physical evaluations, which were recorded as health scores as previously described (Schäfer et al, 2008). Every animal received daily physical examinations, including observations on rectal temperature, ease of cough induction by manual compression of the trachea, fecal consistency, nasal discharge and presence and severity of ocular or otic abnormalities, which were aligned with specific respiratory, gastrointestinal (GI), and pyrexic disease events and subsequent predetermined medical treatment regimens.…”

“…Blood samples were allowed to clot for 18 hr at room temperature before the serum was removed and stored at 4 C. Serum samples were analyzed by the University of Wisconsin, School of Veterinary Medicine's clinical pathology laboratory. Calves with IgG levels  1000 mg/dL (Weaver et al, 2000;Schäfer et al, 2008), and total protein levels  5.0 g/dL were considered to have adequate passive transfer, and calves with lower levels were classified as having failure of passive transfer and subsequently removed from the trial. Calves were also removed from the trial if their starting weight did not fall between 32 and 54.5 kg, or if they died within 48 hr of arrival at the calf-raising farm.…”

“…The documented effects of noni juice include anti-inflammatory, antiangiogenic, anticancer, antibacterial and antioxidant activities. Noni has been reported to modulate immune cells and has been found to enhance the adaptive immune response by activating T and B cells (9).…”
