Abstract
The objective of the study was to compare the effect of a probiotic and an antibiotic as additives in the productive behavior of pigs in the growth phase. 20 pigs were used, male and female, Landrace-Belgian, Pietrain, Yorkshire and Duroc-Jersey crossbreed, 60 days old, distributed in two experimental groups. The probiotic Lacto-Sacc® and the antibiotic Avoporcin were used. The group that was given the Lacto-Sacc® probiotic was the one that obtained the highest final live weight, the best total and daily weight gain, the best feed conversion, and the benefit-cost ratio. It is concluded that probiotic additives improve the productive and sanitary behavior of pigs in the growth phase.
