Abstract In neonates, rapid change in diet imbalances gut health allowing colonization of opportunistic pathogens that confer harmful effects on animal health causing reduced digestion and malabsorption of nutrients. In this milieu, probiotic feeding can be a promising approach in promoting animal health and stabilization of gastrointestinal microbiota. Hence, the present study was designed to investigate the effect of Lactobacillus acidophilus NCDC15 enriched fermented milk on nutrient digestibility, faecal biomarkers and immune response in Murrah buffalo calves. Twenty-four, neonatal calves (5-7 days) were randomly allocated into four groups for 90 days. The control group (CT) was provided a basal diet of calf starter and green fodder (maize and jowar), without any probiotic fermented milk (PFM) supplementation. Basal diet was supplemented with probiotic fermented milk at 100, 200 and 300 mL/calf/day, in PFM100, PFM200 and PFM300 groups, respectively. Nutrient digestibility remained similar among the groups. Faecal acetate was higher (P<0.05) in PFM200 and PFM300, while, faecal butyrate was increased (P<0.05) with all levels of probiotic supplementation than control. Faecal Lactobacillus and Bifidobacterium count were increased (P<0.05) with a concomitant reduction in coliform population (P<0.05) among all the treatments. Cell-mediated and humoral immune response were higher (P<0.001) in PFM200 and PFM300 than CT. Overall, it can be concluded that inclusion of Lactobacillus acidophilus NCDC15 in the form of fermented milk upto 300 mL/calf/day improved immunity and faecal biomarkers in Murrah buffalo calves without any adverse effect on nutrient utilization which may positively impact growth performance in Murrah buffalo calves.
