With the objective of evaluating the repercussion of Lactobacillus acidophilus and Kluyveromyces fragilis L-4UCLV on the productive indicators and the health of the pigs in the different productive stages, two experiments (I and II) were carried out. 14 and 42 hybrid pigs CC21 (Yorkshire - Landrace / L35 Duroc) were used, respectively, distributed in two and three groups of 7 and 14 animals each. Control (T1); prepared-A (T2) and prepared-B (T3). T2, contained L. acidophillus and T3, L. acidophilus more K. fragilis (L-4 UCLV). A completely randomized design was used to evaluate weight gain (WG), average daily gain (ADG), feed conversion (FC), food efficiency (FE), incidence of diarrhea and mortality. WG, ADG, FC and FE were higher (p<0.05) in T2 in experiment I and in T3 in the second. The incidence of diarrhea and the percentage of mortality was lower (p <0.05) in T2 and T3. In conclusion, with the use of probiotic preparations, the productive parameters are improved and the incidence of diarrhea and mortality in all the stages studied is reduced.
