摘要
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.

为了评估对生产性能和放牧犊牛健康使用Sorbial®益生菌，这项研究是在EEPF“印第安人哈土依”，在一年（雨季和旱季）进行。两种处理进行评价：a）浓缩的商业加100克益生菌，和B）的商业浓缩物（对照处理）。该bromatological组成，活重，平均日增重（MDG），胃肠线虫和血液学轮廓的粪便卵数（FEC）进行了分析。配合使用对动物健康的益生菌既不消极行动，也不胃肠疾病（腹泻），进行观察。活重表明显著差异（P 0.05），有利于实验组的动物相比，对照。同样，（克/ ANI-MAL /天758）雨季的动物，吃益生菌期间观察到显著的影响（P 0.05）。另一方面，将FEC没有显示显著的差异;血液学指标有类似的性能，组之间，作为对这种动物类的允许范围内。为了进一步研究这个课题在今后的研究建议。
