The aim of this study was to evaluate the supplementation of Lactobacillus casei in sows and its effect on the zootechnical parameters of piglets. A total of 18 F1 Landrace x Large White sows were distributed in three completely randomized groups: control and two groups supplemented with L. casei (T1: 10 x 106 CFU [colony forming units]; T2: 10 x108 CFU). The doses were administered weekly orally 2 h after the first feeding of the day (09:00) for 180 days, covering a productive cycle. Results of zootechnical variables of each female and her piglets at the peripartum, at weaning and at the new service of the female were evauated. In the peripartum, a greater mean body weight of total births (PPNT) and average birth body weight were found (PPNV) in the supplemented animals compared to the control group (p<0.05). In the lactation phase there was a greater total weight per litter at weani...
