Development of resilience indicator traits based on daily step count data for dairy cattle breeding

Table 1 Descriptive statistics of potential resilience indicators based on daily step count

Resilience indicator^a	Number of records parity 1	Number of records parity 2	Number of records parity 3	Mean	SD	Min	Max
Mean complete lactation	6877	6059	4593	10.90	769.63	− 2912.94	3518.49
Mean early lactation	3555	4712	3632	405.50	1142.96	− 3913.73	5803.58
Mean later lactation	6452	5567	4122	− 55.89	741.57	− 3133.34	3143.33
Mean prepartum	2030	4303	3336	− 97.99	1143.46	− 4650.73	4859.06
Mean negative residuals	6800	6005	4524	− 620.29	281.01	− 1876.08	− 157.27
LnVar_steps	6830	6041	4556	13.18	0.87	10.34	16.28
r_{auto_steps}	6825	6042	4555	0.32	0.19	− 0.43	0.89
Number of step count drops	6826	6042	4556	1.39	0.70	0.00	4.11
Mean residuals during step count drops	6816	6023	4534	− 685.34	429.89	− 2528.28	0.00

Step count data were adjusted for herd x month, which explains the low means
^aLnVar_steps = natural log-transformed variance of step residuals; r_{auto_steps} = lag-1 autocorrelation of step residuals; SD standard deviation
