The Effect of Fermented Kefir as Functional Feed Additive in Post-Weaned Pigs

The control of the immune system pigs after weaning is important in pig farming because productivity depends on survival post-weaned pigs. Previously, antibiotics would have been administered case infectious diseases to increase rate pigs, but now, use strictly restricted order prevent other problems such as occurrence antibiotic-resistant pathogens. In this study, effect fermented kefir a functional feed additive replacement was evaluated terms microbial profile fecal samples, immunological factors blood growth performance measured average daily gain (ADG) and conversion (FCR) kefir-treated group, number lactic acid bacteria Bacillus spp. samples increased with treatments. Interestingly, coliform groups opportunistic pathogens reduced treated kefir. We found out that treatment enhanced innate immunity though reduction IL-6 proinflammatory cytokine an IgG immunoglobulin, enhancing defense against Finally, kefir, we observed ADG 135.6% FCR decreased 92.2%. Therefore, study shows can be used antibiotic alternative improve both
