Diarrheal diseases of calves are one of the most serious risks of rearing calves and cause economic losses. For this reason, the objective of this work was to assess the influence of means of support in operating conditions for the incidence of diarrheal disease in calves in the early post-weaning stages. A company was chosen for this work in which both the company employees and an external veterinarian were willing to collaborate and provide not only information about the breed in question, but also biological material. This company was JINOS - AGRO Veselí nad Lužnicí. The calves were observed in the period of April - June 2009. The calves were housed in separate boxes the second day after birth until the average age of 56 days. After storage, they were divided into 5 groups: 4 based on the chosen means of support, and a single control group. Faeces samples were collected from the calves and subsequently evaluated. The calves to whom were administered means of support were then evaluated to assess the effect thereof on the incidence of diarrhea, the duration of diarrhea, the method of treatment, and the duration of treatment. The results were summarized and analyzed using a statistical program (STATISTICA 7.0.). There was no statistically significant difference found between the individual groups and the experimental group. An evident and statistically significant difference was found only in the case of a difference between the drugs of the 2 experimental groups, specifically between Lactovita and Homeopatika. Based on this observation, it can be stated that there was no evidence supporting the effectiveness of administered means of support for the incidence of diarrheal disease in calves in the early post-weaning stages.
