The research was carried out in the dairy stable ““El Milagro““, located in the district of Huanchaco, department of La Libertad, Peru, with the objective of determining the effect of the addition of probiotic strains in milk on the productive parameters of calves at weaning. To that end, 10 Holstein heifers, separated from their mothers after bi rth, these calves received colostrum for three days and milk from the fourth day of birth, randomly separated into two groups of equal number of calves that received the following treatments: SP: Milk without Probiotic strains and CP: Milk with probiotic strains; these calves received Probiotic strain by three consecutive days from the fourth day of birth. No significant statistical differences were calculated in the parameters of total weight increase, weekly and total feed intake (P> 0.05). Despite the percentage of diarrhea was 0% and 40% in with and without probiotics respectively, no statistical differences were founded (P> 0.05). It is concluded that the addition of probiotic strains in the feeding of calves for three days does not influence signi ficantly the parameters that were studied.
