Probiotic liquid for piglets in different ages

Abstract

The purpose in this study was to evaluate the effect of oral administration of liquid composed by probiotic Lactobacillus reuteri (1.5 x 109 CFU/g) and Bifidobacterium pseudolongum (1.5 x 109 CFU/g), at different ages of piglets on the number of weaners, mortality rate, weight gain, consumption of feed, occurrence of diarrhea and colonization of fecal microbiotic at the stage of lactation. It was used a completely randomized design with six treatments, six repetitions. Regarding the assessment of fecal microbiotic, three repetitions were held. Treatments consisted of: negative control; administration of chemotherapy (bacteriostatic and bactericide); administration of probiotic before the intake of colostrums; administration of probiotic six hours after ingestion of colostrums; administration of probiotic three days of age; administration of probiotic ten days old. There were no significant differences among treatments on the number of weaners and mortality. The administration of probiotic before receiving the colostrum and six hours post-colostrum provided a higher consumption of diet in the first phase of lactation. In the assessment of occurrences of diarrhea and the microbiological evaluation at seven days of age, there was no significant difference between treatments. At fourteen days, the piglets who received probiotic before the colostrum and probiotic to 10 days old showed a higher concentration of Clostridium perfringens. The pigs that received the probiotic at three days of age had lower concentrations of Lactobacillus. There was no significant difference (p<0.05) among treatments in relation to the concentrations of Enterobacteriaceae and total anaerobic bacteria.
