Possibilities of the application of supplemental and nonconventional methods in prevention and health care in calves
RAABOVÁ, Marcela
Diarrhoeas in calves pose one of the most serious risks of calf management and cause economic losses. This is the reason why the objective of this paper was to evaluate in operation conditions the effect of selected dietary supplements on the frequency of diarrhoea occurrence in calves in the first stages of the period after weaning for milk nutrition. An agricultural enterprise where the workers were willing to cooperate and provide the biological material was selected: ZEFA Volary. In 2005 {--} 2008 calves were examined from 3 to 6 weeks of age on average. After filling the facility, the calves were divided into a control and experimental group. Blood and faeces samples were taken in selected calves of both groups and subsequently they were evaluated. The calves were treated with dietary supplements and their effect on the frequency of diarrhoeas was subsequently evaluated on the basis of the results of blood examination and recorded data (diarrhoea occurrence, diarrhoea duration, length of treatment, method and length of treatment, date of filling the facility and date of calf load-out, weight at the time of filling and load-out). The results were summarised and evaluated by a statistical programme (STATISTICA 7.0.). No statistically significant difference was proved between the particular calves of the control and experimental group. Based on our observations the effects of the treatment with dietary supplements on the frequency of diarrhoea occurrence in calves were not satisfactory in the first stages of the period after weaning for milk nutrition. But it is to state that some tendencies to reach a higher average weight gain were observed in calves of the experimental group in applied dietary supplements even though these results were statistically insignificant.

Lactobacillus casei DN 114 001 belongs to one of the most studied probiotics today. The aim of this study was to determine whether this fraction isolated from probiotics can alleviate the course of intestinal inflammation
