  • Thirty two Holstein female calves (initial body weight = $40{\pm}3.0$ kg) were used to investigate the effects of probiotic and prebiotic on average daily gain (ADG), fecal E. coli count, white blood cell count, plasma IgG1 level and cell-mediated immune response to injection of phytohemagglutinin in suckling female calves. Calves were assigned randomly to one of the four treatments, including whole milk without additives (control), whole milk containing probiotic, whole milk containing prebiotic and whole milk containing probiotic and prebiotic (synbiotic). Average daily gain was greater in calves fed probiotic, prebiotic and synbiotic at weeks 6, 7 and 8 (p<0.05). E. coli count was significantly lower in calves fed probiotic, prebiotic and synbiotic on d 56 (p<0.05). There was no significant difference between treatments in blood samples and cell-mediated response. This study showed that addition of probiotic, prebiotic and combination of these additives to milk enhanced ADG and reduced fecal E. coli count in preruminant calves.

  • Probiotics beneficially affect the health of the host via various mechanisms in the intestine. Recent developments in probiotic products have mainly been made to maximize probiotic effects in human. In this regard, probiotic products containing doubly coated or encapsulated cells, multi-species probiotics, or high viable cell number (1010 viable cells/gram or more) have been developed and are already available in the market. Until now, the majority of probiotics contain live cells but little attention has been paid to other alternative products such as heat-killed cell or bacteriocin-containing ones, which could have broad applications due to advantages over live cell-based probiotics, such as safety and stability. In addition, genetically engineered lactic acid bacteria could be of great importance in the field of alimentary health if they are carefully designed for biological safety. Although a number of probiotics are marketed by claiming health benefits, regulations for health claims will be more stringent. Therefore sufficient scientific and clinical evidences supporting the safety and efficacy of the potential probiotic strain will be required by the regulatory authority for a health claim, which thus may have a huge impact on the future probiotic market.
