DATA & FILE OVERVIEW File List: “Study 1_Data_full”, “Study 1_Dishabituation”, “Study 1_Data_sniffing_overtime”, “Study 2_Data_full_RubRoll”, “Study 2_Individual_data_RubRoll”. METHODOLOGICAL INFORMATION Description of methods used for collection/generation of data: All behaviour included in the data files were extracted from digital video recordings made using GoPros (Hero 9). Behavioural recoding methods used can be found in the affiliated publication: https://doi.org/10.3389/fnbeh.2023.1173298. Methods for processing the data from Study 1: Behavioural recoding methods used can be found in the affiliated publication: https://doi.org/10.3389/fnbeh.2023.1173298. Methods for processing the data from Study 2: Submitted manuscript titled “Rub ‘n’ roll – pigs, Sus scrofa domesticus, display rubbing and rolling behaviour when exposed to odours” People involved with sample collection, processing, analysis and/or submission: Johanna Stenfelt, Rebecca Grut, and Maria Vilain Rørvang, Swedish University of Agricultural Sciences, Dept. Biosystems and technology, Alnarp, Sweden. DATA-SPECIFIC INFORMATION FOR: [Study 1_Data_full] Number of variables: 20 Number of cases/rows: 829 Variable List: Each row represents one pig pair (i.e., 2 pigs), hence this data is at pair level. Specific odor and odor type (essential oil (=E)or synthetic perfume (=P)) is given. Odour sequence refers to the different sequences of the triads of odors tested A-Y. Trial represents the odor presentation: 1st, 2nd, and 3rd. All behaviours are measured in seconds, a part from the "No approach" column which is a 1/0 variable = no approach or not. Missing data codes: Missing data is represented by “na”/”NA”. DATA-SPECIFIC INFORMATION FOR: [Study 1_Dishabituation] Number of variables: 8 Number of cases/rows: 369 Variable List: The response variable "Sniff" is the same as in Data_full but data is arranged differently in order to investigate 3rd vs 1st presentations. Odor and odor type is given as in Study 1_Data_full, and odor comparison is given. Trial refers to the presentation as in Study 1_Data_full, with only the 3rd and 1st presentations included. Comparison number a or b refers to which of the two comparisons within each pig pair, a being the first transition from the 3rd presentation of the first odor to the 1st presentation of the new (second) odor, whereas b refers to the 3rd presentation of the second odor, compared with the subsequent 1st presentation of the new odour (third). The order column illustrates the order of each variable. Missing data codes: Missing data is represented by “na”/”NA”. DATA-SPECIFIC INFORMATION FOR: [Study 1_Data_sniffing_overtime] Number of variables: 6 Number of cases/rows: 829 Variable List: Study 1_Data_sniffing_overtime contains the variable sniffing of the odor, but with odors anonymised, and only odor number represented: odor 1, 2 and 3. Missing data codes: Missing data is represented by “na”/”NA”. DATA-SPECIFIC INFORMATION FOR: [Study 2_Data_full_RubRoll] Number of variables: 10 Number of cases/rows: 829 Variable List: The full data "Study 2_Data_full_RubRoll" contains all variables described above, split by odor vs control. This data contains 10 columns, and 829 rows. Each row represents one pig pair (i.e., sum of 2 pigs), hence this data is at pair level (pig pair is given in the first column). Specific odour and odour type (essential oil (=E)or synthetic perfume (=P)) is given. Presentation refers to the presentation number within one odour i.e., 1st, 2nd or 3rd presentation of the same odour. Order refers to which odour in the order of total three odours presented i.e., odour 1, odour 2, or odour 3. All behaviour durations are measured in seconds, and frequencies are measures as total occurrence for the pig pair, per presentation. Missing data codes: Missing data is represented by “na”/”NA”. DATA-SPECIFIC INFORMATION FOR: [Study 2_Individual_data_RubRoll] Number of variables: 14 Number of cases/rows: 140 Variable List: The "Study 2_Individual_data_RubRoll" data sheet contains data used to investigate the behaviours at individual level. The data sheet contains 14 columns and 140 rows. This number of rows are lower due to exclusion of the many individuals not expressing the focus behaviours (rubbing or rolling or rolling attempt). Odour and odour type is given as in Study 2_Data_full_RubRoll, and odour number refers to which odour out the total three (1, 2 or 3). Presentation refers to the same as for Study 2_Data_full_RubRoll, the presentation number within one odour i.e., 1st, 2nd or 3rd presentation of the same odour. Weight is given in kilograms (kg), and breed abbreviation is as follows: Z=Dutch Yorshire, Y=Swedish Yorkshire, H=Hampshire, D=Duroc, and L=Lantrace, the combinations of letters thus indicate the cross with the dam shire listed first, and the number of letter indicating the level of the breed (ZZ=more Dutch Yorkshire than Z). Age of the pig given in days, and breed (cross breeds), and sex (female or male) is also given. Missing data codes: Missing data is represented by “na”/”NA”.
