Faecal culturable microbiota, growth and clinical parameters of calves supplemented with lactic acid bacteria and lactose prior and during experimental infection with Salmonella Dublin DSPV 595T

The aim of this study was to evaluate the probiotic inoculum + lactose effect on weight, intestinal culturable microbiota, morbidity and mortality of young calves challenged with Salmonella Dublin DSPV 595T. Twenty eight calves were used, divided in control group (CG) and probiotic group (PG). The P...

Twenty eight calves were used, divided in control group (CG) and probiotic group (PG). The PG was provided with 100 g lactose.calf-1.d-1 and 10(10) CFU.calf-1.d-1 of each strain of a probiotic inoculum composed of Lactobacillus casei DSPV 318T, Lactobacillus salivarius DSPV 315T and Pediococcus acidilactici DSPV 006T throughout the experiment. The pathogen was administered on day 11 of the experiment, at an oral dose of 10(9) CFU.calf-1. Lactobacillus and yeast populations were modified in PG because of inoculum + lactose administration.
