Does the scan sampling method reflect the actual behavioral frequency of pigs?

<p><strong>Animal behavior studies employ various methodologies to collect the frequency of activities during observations. </strong>The use of video recording technologies as a way to facilitate the observation of several animals at the same time, eliminate doubts among observers, and optimize the observation time contributes to proper analysis of data.<strong> </strong>The intervals between observations in behavioral studies vary according to the <strong>animal species and purpose of the study. </strong>This research aimed to study the behavior of pigs in the growth phase using different observation intervals (continuous, 5, and 10 min).<strong> </strong>In a pen with 46 animals, 14 female and male pigs were identified, which were observed using the focal <strong>animal sampling method for 5 h. </strong>The treatments were the observations intervals, namely: T1 = continuous, T2 = every 5 min, and T3 = every 10 min.<strong> </strong>It was seen that, among the behaviors analyzed during the experiment, the different observation intervals did not impact <strong> the time the animals spent in the activities.</strong><strong></strong></p>
