Abstract:
The selection of promising specific species of lactic acid bacteria with potential probiotic characteristics is
of particular interest in producing multi species-specific probiotic adjuncts in veal calves rearing. The aim
of the present work was to select and evaluate in vitro the functional activity of lactic acid bacteria,
Bifidobacterium longum and Bacillus coagulans strains isolated from veal calves in order to assess their
potential use as multi species-specific probiotics for veal calves. For this purpose, bacterial strains isolated
from faeces collected from 40 healthy 50-day-calves, were identified by RiboPrinter and 16s rRNA
gene sequence. The most frequent strains belonged to the species B. longum, Streptococcus bovis, Lactobacillus
animalis and Streptococcus macedonicus. Among these, 7 strains were chosen for testing their
probiotic characteristics in vitro. Three strains, namely L. animalis SB310, Lactobacillus paracasei subsp.
paracasei SB137 and B. coagulans SB117 showed varying individual but promising capabilities to survive
in the gastrointestinal tract, to adhere, to produce antimicrobial compounds. These three selected
species-specific bacteria demonstrated in vitro, both singularly and mixed, the functional properties
needed for their use as potential probiotics in veal calves.
