Abstract
Animals are subjected, at the moment the sucking pig cannot produce an adequate immunological activity, to several stress types during waning, due to the fact that the passive immunity acquired at the colostrum is gradually reduced and the sucking pig has a low immunological response during post weaning. Objective. Determine the effect of probiotics (Lactobacillus acidophilus, Lactobacillus casei and Enterococcus faecium) on the populations of immune cells in the blood of weaners. Materials and methods. The experiment was made with 80 weaners with 2 days of age, fed with two diets: commercial diet with and without probiotics. For the first, different probiotics were added in the weaner ́s water. A blood sample was taken from the jugular vein at the 1, 15 and 30 post weaning days. A randomized blocks design was used, arranged with repeated measures during time. Every animal was randomized to one of 15 treatments (5 diets*3times). Results. A significant increase (P<0.01) in the number of immune blood cells and of the number of vaccine antibodies in the animals that consumed E. faecium, in comparison to those that consumed the diet with antibiotics. Conclusions.E. faecium improves the animal ́s response to stressful stimuli such as weaning, having a controlled increase of immune blood cells
