To evaluate the use of Sorbial® probiotics on the productive performance and health of grazing calves, this study was conducted at the EEPF "Indio Hatuey", during a year (rainy and dry seasons). Two treatments were evaluated: A) commercial concentrate plus 100 g of probiotic, and B) commercial concentrate (control treatment). The bromatological composition, live weight, mean daily gain (MDG), fecal egg count (FEC) of gastrointestinal nematodes and hematological profile were analyzed. With the use of probiotic neither negative actions on animal health, nor gastrointestinal diseases (diarrhea), were observed. The live weight showed significant differences (P<0,05), favoring the animals of the experimental group as compared to the control. Likewise, a significant effect (P<0,05) was observed during the rainy season in the animals that ate probiotics (758 g/ani-mal/day). On the other hand, the FEC did not show significant differences; the hematological indicators had a similar performance, between groups, being within the permissible ranges for this animal category. To study further this topic in future research is recommended.
