Inclusión de lactobacillus plantarum en la alimentación de cerdas gestantes y lactantes sobre el desempeño de la camada

In order to evaluate the effect of the Lactobacillus plantarum probiotic on feeding pregnant and lactating sows on litter performance, an investigation was conducted at a commercial farm located in the Betania Sector of Canton El Carmen, province of Manabí. The variables studied were: number of piglets per litter (NPL), litter weight at birth (LWB), at 15 days (LW15) and at weaning (LW), piglet weight at birth (PWB), piglet weight 15 days (LW15 ) and at weaning (WPW), daily weight gain (DWG), piglet mortality (% M), body condition (BC) of sow before delivery (BCBF) and at weaning (BCW), the relationship was also determined cost-benefit. Were used 12 primiparous sows with 90 days in gestation. The experimental design used was completely randomized with three treatments and four repetitions: T0: control, without probiotic application; T1: 20 mL of probiotic (109UFC/ml) per kg of food and T2: 40mL of probiot (1010UFC/mL) per kg of food. Data were processed by analysis of variance. The results indicate that the use of probiotics showed no significant differences (P> 0.05) for LWB, LW15, and PW15. Showing differences (P <0.05) by the non-parametric route for: LWB, LWW and PWW. The DWG did not show significant differences (P> 0.05), however, the average DWG was higher than the T0. The statistically variable mortality showed no significant differences (P> 0.05). The BC of the sow was the same before delivery and at weaning. The benefit-cost ratio shows profitability in the three treatments, with T0 being higher.
