Table 2. Association between stop response and object exploration in cows that explored the bilateral balloons with their nose.

Test day	Stop position	N cows showing stop response	Side of object exploration in cows stopping in response to bilateral balloons		X2	P—value

Day 1	At a distance	15	10	5
	At objects	105	34	71	6.88	0.032
	No stop	16	7	9

Day 2	At a distance	11	6	5

	No Stop	27	16	11

Number of cows displaying a stop at distance, stop at the object or no stop in response to the bilateral balloons in association (chi-square) with side preference for exploring the bilateral balloons. Only cows that made physical contact with the objects on either side were included in data analysis.
