Monitoring of an incidence of a behavioral indicators during 24 hours of observation of Belgian landrace pigs and its crossbreeds

We would like to present the results of observations during 24 hour long time period while we focused to the incidence of the behavioral indicators of the Belgian Landrace breeds and its crossbreeds with Duroc. The experiment took place in conditions of Experimental and Slaughter Facility of the Slovak Agricultural University in Nitra, Slovakia. We used the descriptive method of a direct observation, while the noticeable indicators as well as their length were recorded down to the prepared protocols. The results point at necessity to make comparable observations among various conditions, whereas to all conditions has a common validity. Among the observed groups, that were made according their weight, we detected statistically important relationships among 24 hour time period and 3 and 6 hour long segments, which began at 6 AM. At the base of achieved results we can recommend to reduce next observations just to these periods that starts at 6 AM. The shorten time period with its express value has a great influence for use of study of etologic demonstrations in practice.
