对刻板印象的频率、社会互动的性质以及母猪或仔猪是否开始和终止成功哺乳进行了比较。将商业农场的母猪圈养在板条箱或围栏中，并研究一年。我们的观察表明，母猪在板条箱（14.9每母猪小时）比母猪在圈（0.3每母猪小时）显着更多的刻板印象。真空咀嚼是观察到的最普遍的刻板印象（69%）。77%的刻板印象是在喂食前记录的。频率扫描导致更少的刻板印象，每母猪小时比直接连续采样，除了狗坐的位置。这一发现表明，频率扫描是一个上级的方法比直接连续采样采样刻板行为。栏中母猪有显着更具侵略性的相互作用（0.8每母猪小时）比母猪在围栏（0.3每母猪小时）。笼舍设计不影响成功哺乳的比例。母猪开始哺乳的成功率（77%）显著高于仔猪（23%）。我们的观察证实，提供稻草和运动空间可以减少刻板印象的频率（每播种小时14.9），但不能完全抑制它们（每播种小时0.3）。所获得的结果证实了以前的报告表明，住房设计影响的频率定型和母猪之间的社会互动的性质。
The frequency of stereotypies, the nature of social interactions and whether sows or piglets initiate and terminate successful sucklings were compared. Sows on a commercial farm were housed in either crates or pens and studied for a year. Our observations indicated that sows in crates developed significantly more stereotypies (14.9 per sow-hour) than sows in pens (0.3 per sow-hour). Vacuum chewing was the most prevalent stereotypy observed (69%). Seventy-seven percent of the stereotypies were recorded before feedings. Frequency scanning resulted in fewer stereotypies per sow-hour than direct continuous sampling, with the exception of dog-sitting position. This finding suggests that frequency scanning is a superior method for sampling stereotyped behaviour than direct continuous sampling. Sows in crates had significantly more aggressive interactions (0.8 per sow-hour) than sows in pens (0.3 per sow-hour). Housing design did not influence the proportion of successful sucklings. Sows initiated significantly more often (77%) successful sucklings than piglets (23%). Our observations confirm that providing straw and space for exercise reduced the frequency of stereotypies (14.9 per sow-hour), but did not completely suppress them (0.3 per sow-hour). The results obtained confirmed previous reports indicating that housing design influences the frequency of stereotypies and the nature of social interactions between sows.
