MEJIA-SILVA, Willian et al. Evaluation of two probiotics upon productive parameters in suckling piglets. Zootecnia Trop. [online]. 2007, vol.25, n.4, pp.301-306. ISSN 0798-7269.

The objective of this study was to evaluate the effect of two treatments on body weigh at weaning (BWW) and average daily gain (ADG). In this trial were used 194 Yorkshire x Pietrain and Landrace x Pietrain piglets, in a commercial farm in Zulia state, Venezuela. Experimental units were randomly and distributed in two treatment groups, control (C) and experimental treatment (E). The first of them was represented by a commercial probiotic (Lactobacillus reuferill, L. lactis, L. acidophillus, L. casei, Pediococcus acidilacti; Streptococcus termophillus, and S. faecium) with addition of vitamin B12, copper, inmunoglobulins, and triglycerides selectioneers. The experimental treatment (E) was represented by fermented milk, which number of lactic bacteria was log UCF/g of 7.48. A completely random experimental design, with one independent variable (Treatment) was used, and each sow was nested into treatments. The body weight and daily weight gain were reported as dependent variables. Data was analyzed using GLM procedures of SAS. There were no significant effects (P>0.05) between treatments. The results suggest that the use of handmade fermented milk could be a good alternative to achieve good average daily gain at weaning decreasing the diarrhea rate in sucking piglets
