LAB are present in the reproductive tract of healthy cows (Otero et al., 2000) being the first colonizers of the intestinal tract of calves, where prevent pathogen entry. Postpartum metritis and diarrhea are two of the main causes of losses in bovine heard productivity. A probiotic product could be a sustainable treatment to prevent these infectious diseases, and decrease adverse effects mainly those caused by antibiotics in breeding systems (spread of resistance and food contamination). Probiotics are ?live microorganisms administered to the host to produce a beneficial physiological effect? (Reid et al,2003). Our main objective is the design of a veterinarian vaginal product containing beneficial LAB (vaginal and intestinal strains) to restore the reproductive tract microbiome and to colonize the newborn calf mucosa. Therefore, the selected LAB should be able to maintain the viability in the formula and grow in the host conditions.
